(PHYTOTHERAPY)
DIPLOMA COURSE
ASSIGNMENT ONE
HISTORY OF HERBAL MEDICINE
TUTOR TALK: The Learning Outcomes for this assignment are:
• Demonstrate how the Thalidomide tragedy changed people’s perception of
orthodox medicine.
• Summarise the contributions made to Herbalism by Culpepper and Dioscorides.
• Explain through examples what the Doctrine of Signatures means.
TUTOR TALK: This course covers herbal medicine, aromatherapy and flower essences -
all therapies that use plants in some way or another. At the end of this course you will
understand and hopefully will have learned a lot about the herbalist theories associated
with plants. You will not be qualified to stock your own herbs or to sell to the public but
you will be able to treat any client using tinctures and herbal remedies that have been
purchased from manufacturers and also to keep your own family and friends healthy, with
home grown herbs.
You will also be able to make up externally used herbal remedies like poultices for any
client. You will also understand the theory of aromatherapy but alas not the practical
massage. Flower essences do not require such a practical course and are harmless yet
potent medicines for many ailments especially emotional, mental and spiritual.
BEGINNING OF HERBAL MEDICINE
From The Earliest Times, medicinal plants have been crucial in sustaining the health and the well
being of mankind. Linseed, for example, provided its harvesters with a nutritious cooking oil, fuel, a
cosmetic balm for the skin and fibre to make fabric. Additionally it was used to treat conditions such
as bronchitis, respiratory catarrh, boils and a number of digestive problems. Given the life-enhancing
benefits that this and so many other plants provided, it is hardly surprising that most cultures
believed plants to have magical as well as medicinal properties. It is equally reasonable to assume
that for tens of thousands of years herbs were probably used as much for their ritual magical powers
as for their medicinal qualities. A 60,000-year-old burial site excavated in Iraq, for instance, was
found to contain eight different medicinal plants, including ephedrine. The inclusion of the plants in
the tomb suggests they had a supernatural significance as well as having medicinal benefits.
In some cultures, plants were considered to have souls. Even Aristotle, the 4th-century BC Greek
philosopher, thought that plants had a “psyche”, albeit of a lesser order than the human soul.

In Hinduism, which dates back to at least 1500 BC, many plants are still sacred to specific divinities.
For example, the Bael tree is said to shelter Shiva, the god of health, beneath its branches.
In medieval Europe, the Doctrine of Signatures stated that there was a connection between how a
plant reflected God’s “signature” and how it might be used medicinally. For example, the mottled
leaves of Lungwort were thought to resemble lung tissue – even today the plant is used to treat
ailments of the respiratory tract.
In a similar vein, native peoples of the Andes in South America believe that Mama Coca, a spirit
who must be respected and placated if the leaves are to be harvested and used, protects the coca
plant.
Even in Western cultures a belief in plant spirits linger. Until this century, British farm workers
would not cut down elder trees for fear of arousing the anger of the Elder Mother, the spirit who
lived in and protected the tree.
SHAMANISTIC MEDICINE
In many traditional societies today, the world is believed to be shaped by good and evil spirits. In
these societies, illness is thought to originate from malignant forces or because evil spirits have
possessed the sick person. In some societies if a member of the tribe falls ill, the shaman [the
“medicine” man or woman] is expected to intercede with the spirit world to bring about a cure.
Shamans often enter the spiritual realm with the aid of hallucinogenic plants or fungi, such as
Ayahuasca, taken by Amazonian shamans, or Fly Agaric, taken by traditional healers of the Siberian
Steppes. At the same time, the shaman provides medical treatment for the physical needs of the
patient, putting salves and compresses on wounds, boiling up decoctions and barks for internal
treatment, stimulating sweating for fevers, and so on. Such treatment is based on a wealth of acutely
observed plant lore and knowledge, handed down in an oral tradition from generation to generation.
THE DEVELOPMENT OF MEDICINAL LORE
It is generally recognized that our ancestors had a wide range of medicinal plants at their disposal,
and that they likewise possessed a profound understanding of plants’ healing powers. In fact, up until
the 20th century, every village and rural community had a wealth of herbal folklore, Tried and tested
local plants were picked for a range of common health problems and taken as teas, applied as lotions
or even mixed with lard and rubbed in as an ointment.
But what were the origins of this herbal expertise? There are no definitive answers. Clearly, acute
observation coupled with trial and error has played a predominant role. Human societies have had
many thousands of years to observe the effects – both good and bad – of eating a particular root, leaf
or berry. Watching the behaviour of animals after they have eaten or rubbed against certain plants
has also added to medicinal lore. If one watches sheep or cattle, they almost unerringly steer a path
past poisonous plants such as Ragwort or Oleander. Over and above such close observation, some
people have speculated that human beings, like grazing animals, have an instinct that recognizes
poisonous as opposed to medicinal plants.

ANCIENT CIVILIZATIONS
As civilizations developed from 3000 BC onwards in Egypt, the Middle East, India and China, so the
use of herbs became more sophisticated, and the first written accounts of medicinal plants were
made. The Egyptian Ebers papyrus of 1500 BC is the earliest surviving example. It lists dozens of
medicinal plants, their uses and related spells and incantations. The herbs include myrrh, castor oil
and garlic.
In India, the Vedas, epic poems written c. 1500 BC, also contain rich material on the herbal lore of
that time. The Charaka Samhita, written by the physician Charaka.This medical treatise includes
details of around 350 herbal medicines, followed the Vedas in about 700 BC. Amongst them are
Visnaga, an herb of Middle Eastern origin that has recently proven effective in the treatment of
asthma, and Gotu Kola, which has long been used to treat leprosy.
MEDICINE BREAKS FROM MYSTICAL ORIGINS
By about 500 BC in developed cultures, medicine began to separate itself from the magical and
spiritual world. Hippocrates [460-377 BC], the Greek “father of medicine”, considered illness to be a
natural rather than a supernatural phenomenon, and he felt that medicine should be given without
ritual ceremonies or magic.
In the earliest Chinese medical text, the Yellow Emperors Classic of Internal Medicine written in the
1st century BC, the emphasis on rational medicine is equally clear: “In treating illness, it is necessary
to examine the entire context, scrutinize the symptoms, observe the emotions and attitudes. If one
insists on the presence of ghosts and spirits one cannot speak of therapeutics.”
FOUNDATION OF MAJOR HERBAL TRADITIONS 300 BC-AD 600
Trade between Europe, the Middle East, India, and Asia was already well under way by the 2nd
century BC, and trade routes became established for many medicinal and culinary herbs. Cloves, for
example, native to the Philippines and the Molucca Islands near New Guinea, were imported into
China in the 3rd century BC, and first arrived in Egypt around AD 176. As the centuries passed,
cloves’ popularity grew and by the 8th century AD, their strong aromatic flavour and powerfully
antiseptic and analgesic properties were familiar throughout most of Europe.
As trade and interest in herbal medicines and spices flourished, various writers tried to make
systematic records of plants with a known medicinal action and record their properties.
In China, the Divine Husbandman Classic [Shen’nong Bencaojing], a Taoist text written in the 1st
century AD, [in the Han Dynasty] had 364 entries, of which 252 were recognised as being herbal
medicines, including Coltsfoot and Gan Cao. This text laid the foundations for the continuous
development and refinement of Chinese herbal medicine up to the present day. [I have referred to
this text in the herbs monograms as ‘the herbal of the first century].
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 4
In Ethiopia, a 1st-century AD Greek physician named Dioscorides wrote the first European herbal,
Materia Medica. His intention was to produce an accurate and authoritative work on herbal
medicines and in this he was dramatically successful. Amongst the many plants he mentions are
juniper, elm, peony and burdock. The text, listing about 600 herbs in all, was to have an astonishing
influence on Western medicine, being the principal reference used in Europe until the 17th century. It
was translated into languages as varied as Anglo-Saxon, Persian and Hebrew. In AD 512, the
Materia Medica became the first herbal listing to feature pictures of the plants discussed in the text.
Made for Juliana Arnicia, the daughter of the Roman emperor Flavius Avicius Olybritis, it contained
nearly 400 full-page colour illustrations.
Galen’s ‘four humours”, Galen AD 131-200, physician to the Roman emperor Marcus Aurelius, had
an equally profound influence on the development of herbal medicine. Galen drew inspiration from
Hippocrates and based his theories on the “theory of the four humours”. His ideas shaped and, some
would say, distorted medical practice for the next 1,400 years.
In India and in China, elaborate medical systems somewhat resembling the theory of the four
humours developed, they have endured to the present day.
Though European, Indian and Chinese systems differ widely, they all consider that an imbalance
within the constituent elements of the body is the cause of illness, and that the aim of the healer is to
restore balance, often with the aid of herbal remedies.
FOLK HEALING IN THE MIDDLE AGES
The theories of Galenic, Ayurvedic [Indian] and Chinese traditional medicine, however, would have
meant practically nothing to most of the world’s population. As is still the case today for some
indigenous peoples who have little access to conventional medicines, in the past most villages and
communities relied on the services of local “wise” men and women for medical treatment. These
healers were almost certainly ignorant of the conventions of scholastic medicine, yet through
apprenticeship and practice in treating illness, attending childbirth and making use of locally growing
herbs as a natural pharmacy, they developed a high level of practical medicinal knowledge.
We tend to underestimate the medical skills of apparently undeveloped communities – particularly
during the so-called Dark Ages in medieval Europe but it is evident that many people had a
surprisingly sophisticated understanding of plant medicine. For example, recent excavations at an
11th century monastic hospital in Scotland revealed that the monks were using exotic herbs such as
opium poppy and marijuana as painkillers and anaesthetics. Likewise, the herbalists in Myddfai, a
village in South Wales, obviously knew of Hippocrates’ writings in the 6th century AD and used a
wide variety of medicinal plants. The texts that have been handed down from that herbal tradition are
filled with an engaging blend of superstition and wisdom. From a 13th-century manuscript it was
recommended that, to strengthen the sight, take Eyebright and Red Fennel, a handful of each, and
half a handful of Rue, distil, and wash your eye daily.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 5
ISLAMIC & INDIAN MEDICINE AD 500-1500
Folk medicine was largely unaffected by sweeping forces of history, but Western scholastic medicine
suffered greatly with the decline of the Roman Empire.
It was thanks to the flowering of Arabic culture in 500-1300 AD that the gains of the classical Greek
and Roman period were preserved and elaborated. The spread of Islamic culture along North Africa
and into present-day Italy, Spain and Portugal led to the founding of renowned medical schools,
notably at Cordoba in Spain. The Arabs were expert pharmacists, blending and mixing herbs to
improve their medicinal effect and taste. Their contacts with both Indian and Chinese medical
traditions meant that they had a remarkable range of medical and herbal knowledge to draw on and
develop.
Though Avicenna 980-1037 AD, author of Canon of Medicine, was the most famous physician of
the day, perhaps the most unusual herbal connection had been made a century before his time by
Cordoba, an intrepid Arab seafarer, who brought ginseng root from China to Europe. This valuable
tonic herb was to be regularly imported into Europe from the 16th century onwards.
Further east, in India, the 7th century was a golden age of medicine. Thousands of students studied
Ayurveda at university, especially at Nalanda where scholars recorded the medical achievements of
the time. Their recorded advances record the development of hospitals, maternity homes and the
planting of medicinal herb gardens.
CENTRAL & SOUTH AMERICAN CURES
On the other side of the world, the ancient civilizations of Central and South America, Maya, Aztec
and Inca, all had herbal traditions with a profound understanding of local medicinal plants. One
account tells of Incas taking local herbalists from what is now Bolivia back to their capital Cuzco in
Peru because of the herbalists’ great capabilities, which reputedly included growing a form of
penicillin on green banana skins.
At the same time, medicine and religion were still closely interwoven in these cultures, possibly even
more so than in Europe. One gruesome account tells of Aztec sufferers of skin diseases who sought
to appease the god Xipe Totec by wearing the flayed skins of sacrificial victims. Fortunately, a
supernatural appeal to the gods was not the sole means to relieve this and other afflictions. Many
herbs were available as alternative treatments, including sarsaparilla, a tonic and cleansing herb that
was used in treatments for a variety of skin complaints including eczema and psoriasis.
REBIRTH OF EUROPEAN SCHOLARSHIP AD 1000-1400
As European scholars slowly started to absorb the lessons of Arabic medical learning in the early
Middle Ages, classical Greek, Roman and Egyptian texts preserved in the libraries of Constantinople
(later Istanbul) filtered back to Europe, and hospitals, medical schools and universities were founded.
Perhaps the most interesting among them was the medical school at Salerno on the west coast of
Italy. It not only allowed students from all faiths Christian, Moslem and Jewish to study medicine,
but it also allowed women to train as physicians. Trotula, a woman who wrote a book on obstetrics,
practised and taught there in about 1050. Herbs were, of course, central to the healing process.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 6
An adage from the Salerno school on sage went as follows: So/via salvatrix, natura conciliati’ix
[sage, the saviour; nature, the conciliator].
By the 12th century, trade with Asia and Africa was expanding and new herbs and spices were being
regularly imported into Europe. Hildegard of Bingen 1098-1179, the famous German mystic and
herbal authority, considered galangal used in Asia as a warming and nourishing spice for the
digestive system – to be the “spice of life”, given by God to provide health and to protect against
illness.
ASIAN UNIFICATION
Marco Polo’s travels to China in the 14th century coincided with the unification of the whole of Asia
from the Yellow Sea in China to the Black Sea in south eastern Europe by Genghis Khan and his
grandson Kublai Khan. Neither the Chinese nor Ayurvedic medical traditions were directly
threatened by this conquest. The Mongol rulers at the time were strict in banning the use of certain
toxic plants such as aconite, but their decree may have held an element of self-preservation, given
aconite’s alternative use as an arrow poison – one that could have been used against the ruling
powers. Indirectly the Mongol unification may have encouraged at the time far greater
communication between the two medical disciplines.
In other parts of Asia, such as Vietnam and Japan, Chinese culture and medicine exerted the primary
influence. While kan’ipoh – the traditional herbal medicine of Japan – is distinctive to that country
its roots stem from Chinese practices.
TRADE BETWEEN CONTINENTS 1400-1700
Trade routes had slowly expanded during the Middle Ages, bringing exotic new herbs in their wake.
From the 15th century onwards, an explosion in trade led to cornucopia of new herbs becoming
readily available in Europe. They included plants such as ginger, cardamom, nutmeg, turmeric,
cinnamon and senna.
The trade in herbs was not entirely one way. The European herb sage, for example, came into use in
China, where it was considered to be a valuable yin tonic.
The arrival of Columbus’ ships in the Caribbean in 1492 was followed by the rapid conquest and
colonization of Central and South America by the Spanish and Portuguese. Along with their booty of
plundered gold, the conquistadores returned and bought many plants and seeds with them. Garlic is
native to Asia but was readily adopted for its medicinal to the Old World with and culinary qualities
in the West previously unheard-of medicinal plants.
Many of these herbs from the Americas had highly potent medicinal actions, and they soon became
available in the apothecaries of the major European cities. Plants such as lignum vitae and cinchona
with strong medicinal actions were used with greater and lesser degrees of success as treatments for
fever, malaria, syphilis, smallpox and other serious illnesses.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 7
For most rural communities, however, the only foreign plants that were used medicinally were those
that could also be grown locally as foods. Garlic offers one of the earliest and clearest examples.
Originating in central Asia, over time it was cultivated further and further west and was grown in
Egypt around 4500 BC. In Homer’s 8th-century BC epic poem Ulysses, the hero is saved from being
changed into a pig thanks to garlic. The herb was introduced into Britain after the Roman conquest in
the 1st century AD, and by the time it reached the island its remarkable medicinal powers were well
understood. In later centuries, potatoes and maize, both native to South America, would become
common foods. These plants have clear medicinal as well as nutritional benefits. Potato juice is a
valuable remedy for the treatment of arthritis, while cornsilk makes an effective decoction for
urinary problems such as cystitis.
HEALTH & HYGIENE 1400-1700
Between the 12th and 18th centuries the influx of exotic medicinal plants added to an already large
number of useful European herbs. It is even conceivable that an overall improvement of health in
Europe might have resulted. After all, not only were new medicinal plants available, but Europeans
had the opportunity to observe the different medical practices of people in South America, China,
Japan and especially in India, where trade was well established.
In reality the reverse was the case. People living in Europe during this period probably experienced
some of the unhealthiest conditions the world has ever seen. In contrast, Native Americans before the
arrival of Columbus lived longer, healthier lives than their counterparts in Europe. This fact is
unsurprising given the cities of medieval Europe, with their open sewers, overcrowding and a
population generally ignorant of simple hygiene. Conditions such as these laid fertile ground for the
spread of plague-infested rats from the ports of the Mediterranean throughout Western Europe.
From the mid-14th century onwards, plague killed millions, in some cases close to 50 per cent of the
population. No medical treatment – herbal or mineral – was able to alter its fatal course. Epidemics
continued to decimate the cities of Europe and Asia well into the 18th century. Recently an outbreak
in India [in 1994] reawakened the terror inspired simply at the mention of the word “plague”.
European doctors had little success in combating diseases as devastating as plague. The medicine
they practised was based on the blind acceptance of Galen’s humoral principles. Perhaps if, as in
Chinese and Indian medicine, European medicine had continued to evolve, revising ancient medical
texts and reinterpreting them in the light of new discoveries, it would have had greater success. As it
was, European physicians were at least as likely to kill their patients with bloodletting and toxic
minerals in misbegotten attempts to balance the humours, as they were to cure. Indeed, the
increasingly fashionable use of mineral cures such as mercury led to the growth of chemical
formulations, culminating in scientific medicine’s ultimate break away from herbal practices.
THE INFLUENCE OF PARACELSUS
One of the key European figures of the 16th century was Paracelsus 1493-1541, a larger-than-life
character who rejected the tired repetition of Galen’s theories in favour of detailed observation in
medicine. “I have not borrowed from Hippocrates, Galen or anyone else,” he wrote, “having
acquired my knowledge from the best teacher, that is, by experience and hard work.” And again,
“What a doctor needs is not eloquence or knowledge of language and of books, but profound
knowledge of nature and her works.” He also paid great attention to the exact dosage, saying that “it
depends only on the dose whether a poison is a poison or not.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 8
As a result, Paracelsus was an influential force in the future development of chemistry, conventional
medicine, herbal medicine and homeopathy. Though he is known as the “father of chemistry”, be
also explored alchemy, which concerned itself with the transmutation of base materials to gold, and
the search for the immortal life. Paracelsus also revived interest in the Doctrine of Signatures – the
ancient theory that held that a plant’s appearance indicated the ailments it would treat – and affirmed
the value of locally grown medicinal herbs over expensive, imported specimens.
CULPEPER & PRINTED HERBALS
Paracelsus’ advocacy of local herbs was later fiercely espoused by Nicholas Culpeper 1616-1654.
Wounded during the English Civil War fighting for the Commonwealth, Culpeper championed the
needs of the ordinary people who could afford neither the services of a doctor nor the expensive
imported herbs and formulations that doctors generally prescribed. Drawing to some degree on
Dioscorides, Arabian physicians and Paracelsus, Culpeper developed a medical system that blended
astrology and sound personal experience of the therapeutic uses of local plants. His herbal became an
instant “bestseller” and appeared in many subsequent editions. The first herbal published in North
America, in 1700, was an edition of his herbal.
While the popularity of The English Physician was notable, other herbals also found a place in
households. The development of the printing press in the 15th century brought herbal medicine into
homes on a wide scale. Texts such as Dioscorides’ De Materia Medica were printed for the first time,
and throughout Europe herbals were published and ran through many editions.
DEADLY CURES 1700-1900
By the end of the 16th century, Paracelsus had become the figurehead of the new chemical medicine
movement. However, where he had insisted upon caution in the use of metallic poisons – mercury,
antimony and arsenic – the new medical thinkers were not so inhibited. Larger and larger doses of
the purgative known as calomel [mercurous chloride, Hg2C1,] were given to those suffering from
syphilis and many other diseases. The treatment was very often worse than the disease, some patients
died and many more sufferered from the long-term consequences of mercury poisoning.
Hippocrates’ saying “Desperate cases need the most desperate remedies” was taken very literally, as
is evident in the incredible excess of purging and bleeding that developed over the next three
centuries in Europe and North America. These practices reached a peak in the “heroic” medicine of
the early 19th century. Its leading proponent, Dr Benjamin Rush 1745-1813, maintained that only
bloodletting and calomel were required in medical practice. His position was obviously extreme, but
it is clear that in this new climate herbal medicines were becoming increasingly irrelevant.
THE NEW RATIONALISM
Along with the new emphasis on chemical cures, modern medicine came to look askance at the
notion of the “vital force”. Up until the end of the 16th century, nearly all medical traditions had been
based on the concept of working with nature and with the body’s healing capacities, which could be
supported and strengthened with appropriate medicinal herbs.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 9
In traditional Chinese medicine, chi is the primal energy that maintains life and health. In Ayurveda,
it is prana, and in the Western tradition, Hippocrates writes about “vis rnedicatrix naturae” or the
healing power of nature. In modern Western medicine herbalists and homeopaths use the term “vital
force”.
The importance of the vital force was diminished in the West by the philosophy of René Descartes
1596-1650. This French mathematician divided the world into body and mind, nature and ideas. His
philosophy ordained that the intangible vital force that maintains life and governs good health was
the province of religion rather than of the newly self-aware “science” of medicine. To the new
medical establishment, inching its way forward towards scientifically sound medical practices,
“supernatural” concepts such as the vital force were a reminder of the ignorance and superstition that
were part and parcel of older healing practices.
Even before Descartes’ theories, the rational approach to scientific and medical exploration was
beginning to reap rewards. Slowly medical understanding of bodily functions was gaining ground.
William Harvey 1578-1657 made a detailed study of the heart and circulation, proving for the first
time that, contrary to Galenic thought, the heart pumped blood around the body Published in 1628,
his study is a classic example of the revolution in medical science.
Since Harvey’s time, science has had astounding success in revealing how the body works on a
biochemical level and in distinguishing different disease processes. However, by comparison it has
been altogether less successful in developing effective medical treatments for the relief and cure of
diseases.
THE GAP IN THE SCIENTIFIC APPROACH
In hindsight, it seems as if the new science of medicine could only be born in separation from the
traditional arts of healing, with which it had always been intertwined. As a result, even though
traditional medicine has generally lacked scientific explanation, it has frequently been far ahead of
medical science in the way it has been applied therapeutically. In ‘American Indian Medicine’
[University of Oklahoma Press, 1970], Virgil Vogel provides a good example of “ignorant” folk
medicine outstripping scientific understanding in therapeutic application: “During the bitter cold
winter of 1535-6, the three ships of Jacques Cartier were frozen fast in the fathom-deep ice of the St
Lawrence River near the site of Montreal. Isolated by four feet of snow, the company of 110 men
subsisted on the fare stored in the holds of their ships. Soon scurvy was so rampant among them that
by mid-March, 25 men had died and the others, ‘only three or foure excepted’, were so ill that hope
for their recovery was abandoned. As the crisis deepened Cartier had the good fortune to encounter
once again the local Indian chief, Domagaia, who had cured himself of the same disease with ‘the
juice and sappe of a certain tree’. The Indian women gathered branches of the magical tree, ‘boiling
the bark and leaves for a decoction, and placing the dregs upon the legs’. All those so treated rapidly
recovered their health, and the Frenchmen marvelled at the curative skill of the natives:’
Naturally the Native Americans had not heard of vitamin C deficiency, which causes scurvy, nor
would they have been able to explain in rational terms why the treatment worked. Indeed, it was not
until 1753 that James Lind 1716-1794, a British naval surgeon, inspired partly by Cartier’s account,
published ‘A Treatise of the Scurvy’, which showed conclusively that the disease could be prevented
by eating fresh greens, vegetables and fruit, and was caused by their lack in the diet. James Lind’s
work is a marvellous example of what can be achieved by combining a systematic and scientific
approach with traditional herbal knowledge.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 10
ISOLATING CHEMICALS
The discovery of the medicinal value of foxglove is another case where traditional herbal knowledge
led to a major advance in medicine. Dr William Withering 1741-1799, a conventionally trained
doctor with a long interest in medicinal plants, started to investigate foxglove after encountering a
family recipe for curing dropsy (water retention). He found that in some regions of England,
foxglove was traditionally used to treat this condition, which is often one of the indications of a
failing heart. In 1785, he published his ‘Account of the Foxglove’, documenting dozens of carefully
recorded case histories, and showing how foxglove’s powerful and potentially dangerous active
constituents, now known as cardiac glycosides, made it a valuable plant medicine for dropsy.
Cardiac glycosides remain in common use to the present day. Yet despite this clear-cut example of
the possibilities inherent in a marriage of herbal medicine and scientific method, conventional
medicine was to take another path in the 19th century.
LABORATORY VERSUS NATURE
From the early 19th century, the chemical laboratory began to regularly supplant Mother Nature as
the source of medicines. In 1803, narcotic alkaloids were isolated from the opium poppy. A year
later, inulin was extracted from elecampane. In 1838, salicylic acid, a chemical fore-runner of
aspirin, was isolated from white willow bark, it was first synthesized in the laboratory in 1860.
From this point on, herbal medicine and biomedicine were to take separate paths. Aspirin, an entirely
new chemical formulation, was first developed in Germany in 1899. But this was still an early step.
For the time being, the influence of the universities, medical schools and laboratories of Europe
would remain limited, and herbal medicine would prevail as the predominant form of treatment for
most people around the world.
NEW FRONTIERS, NEW HERBAL MEDICINES
Wherever Europeans settled during the great migrations of the 18th and 19th centuries – North
America, South America, southern Africa or Australia – much of the European medicine familiar
from home was either unavailable or prohibitively expensive. Settlers came to learn that native
peoples were a wellspring of information about the medicinal virtues of indigenous plants. For
example, European settlers in southern Africa learned about the diuretic properties of buchu from
native peoples; and Australian settlers came to understand the remarkable antiseptic properties of tea
tree from observing the medicinal practices of the Aborigines. Mexican herbal medicine as it exists
today is a blend of Aztec, Mayan and Spanish herbs and practices.
In North America, native herbalists were particularly adept at healing external wounds and bites –
being superior in many respects to their European counterparts in this area of medicine. This is not
surprising, given the range of highly effective medicinal plants Native Americans had discovered –
including well-known herbs such as echinacea, goldenseal and lobelia.
European settlers learned much from observing native practices. Over the course of the 19th and early
20th centuries, as pioneers moved west across the frontier territory, new plants were constantly being
added to the official record of healing herbs. In addition to the three species mentioned above, about
170 native plants were listed in The Pharmacopoeia of the United States.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 11
SAMUEL THOMSON & HIS FOLLOWERS
Lobelia was one of the key herbs, along with cayenne, advocated by Samuel Thomson 1769-1843,
who was an unorthodox herbal practitioner. He developed a drastically simple approach to medicine
that was entirely at odds with the conventional practices of his time. Thomson’s approach was often
extremely effective and was well suited to the needs of people living in frontier territory. His system
of medicine that was really the earliest form of naturopathy [a form of healing in which symptoms
are treated with herbs, naturally grown food, sunlight and fresh air] became extraordinarily popular,
with millions of people across North America. Thomson’s success waned as other more sophisticated
herbal approaches were developed – those of the Eclectics and Physiomedicalists for example. The
fertile medical world of 19th-century America also saw the birth of osteopathy [a system of healing
based on the manipulation of bones] and chiropractic [a similar system primarily involving
manipulation of the spine].
WESTERN INFLUENCES ON ASIAN MEDICINE
Across the world in China, Thomson’s practices might have been looked on with a measure of
surprise, but they would have been familiar. In Chinese medicine, there has always been a debate as
to what degree illness arises from cold, and to what degree it arises from heat.
The Shanghanbun (On Cold-Induced Maladies), written in the 2nd century AD, and revised and
reinterpreted in commentaries over the last 1,800 years, Ginseng has been used as a tonic remedy in
Chinese medicine for at least 5,000 years.
Opium poppy, native to Asia, yields a resin that has long been smoked for its narcotic effect. Its main
active constituent, morphine, was first isolated in the laboratory in 1803 and is used to relieve pain.
In the 14th century Wang Lu distinguished between cold-induced illness and febrile illness, and
treated them in different ways. These differences were capitalised on by different Chinese herbalists
right up to the 19th century.
During the early 19th century, the influence of Western biomedicine was beginning to affect
traditional practices in both China and India. This was certainly beneficial in many respects. The
judicious incorporation of scientific principles and methods into traditional herbal healing offers the
possibility of greatly refining the effectiveness of treatment. But in India under British rule, Western
medicine eventually became the only alternative.
Ayurveda was seen as inferior to biomedicine. Western practice was introduced not as a complement
to traditional medicine, but rather as a means to supplant it. According to one authority, “before 1835
Western physicians and their Indian counterparts exchanged knowledge; thereafter only Western
medicine was recognised as legitimate and the Eastern systems were actively discouraged” [Robert
Svoboda, Ayurveda, Life, Health and Longevity, 1992].
In China, the influx of Western ideas was less traumatic. Increasing numbers of Chinese medical
students studied Western medicine but this did not stop the continuing development of traditional
herbal practice. By and large, each tradition was recognized as having both advantages and
disadvantages.

HERBALISM OUTLAWED 1850-1900
In Europe, conventional medicine was seeking to establish a monopoly for its own type of practice.
In 1858, the British Parliament was asked to impose legislation banning the practice of medicine by
anyone who had not been trained in a conventional medical school. Fortunately, this proposal was
rejected, but in countries such as France, Spain, Italy and the US it became illegal to practise herbal
medicine without an orthodox qualification. Herbalist’s were forced to risk fines or imprisonment
simply for providing herbal medicine to patients who had sought their help.
In Britain, concerns such as these, combined with a desire to establish Western herbal medicine as an
alternative to conventional practices, particularly in the industrial cities of the North of England, led
to the formation in 1864 of the National Institute of Medical Herbalists, the first professional body of
herbal practitioners in the world. Its history is an example of how tenacious herbal practitioners have
had to be simply to retain their right to give safe, gentle and effective herbal medicines to their
patients.
Even as late as the 1930s, around 90 per cent of medicines prescribed by doctors or sold over the
counter were herbal in origin. It is only during the last 50 years that laboratory-produced medicines
have become the norm. During the First World War 1914-1918, for example, garlic and sphagnum
moss were used by the ton in the battle trenches to dress wounds and to treat infections. Garlic is an
excellent natural antibiotic, and was the most effective antiseptic available at the time, and sphagnum
moss gathered from the moorlands, makes a natural aseptic dressing.
SCIENCE & MEDICINE
The development of new medicines in the laboratory either extracted from medicinal plants or
synthesized – stretches back to the early 19th century, when chemists first isolated morphine, from
the opium poppy, and cocaine, from coca. From that time onwards, scientists made tremendous
progress in understanding how isolated chemicals affect the body, as well as how the body works in
health and disease. From the 1860s, scientists – most notably Louis Pasteur 1822-1895 began to
identify the micro-organisms that were ultimately responsible for causing infectious diseases, such as
tuberculosis and malaria.
Naturally enough, the first aim of those engaged in medical research was to seek out medicines that
would act as “magic bullets”, directly attacking the microorganisms concerned and ridding the body
of the threat presented. This eventually led to the discovery, or, more accurately, the rediscovery of
penicillin by a number of medical researchers, most notably Alexander Fleming 1881-1955 in 1929.
However, while 20th-century scientists were the first to scientifically evaluate antibiotics as
medicines, they were not the first to employ them in healing. Antibiotic moulds had been grown and
used to combat infection in ancient Egypt, 14th-century Peru and in recent European folk medicine.
In the decades following the Second World War 1939-1945, when antibiotics first came into use, it
seemed as though a new era had dawned in which infection could be conquered, and life-threatening
diseases such as syphilis, pneumonia and tuberculosis would cease to be major causes of death in the
developed world. Modern medicine also provided other highly effective drugs such as steroid anti-
inflammatory drugs. It seemed as if it was simply a question of time until cures for most illnesses
were found.

ASCENDANCY OF BIOMEDICINE
As Americans and Europeans became accustomed to medication that led to an almost instant short-
term’ improvement in symptoms if not in underlying health, herbal medicines came to be seen by the
public as outmoded and “cranky”. Increasingly, the practice of herbal medicine was outlawed in
North America and most of Europe, while the wealthy in developing countries abandoned herbal
medicine in favour of the new treatments available.
This was in no small part due to the medical profession itself, which saw herbal medicine as a
throwback to the superstitions of the past. From the late 19th century onwards, the aim of
organizations such as the American Medical Association and the British Medical Association had
been to monopolize conventional medical practice. Herbal medicine thus neared extinction in many
countries, especially in the USA and Britain. In Britain, for example, from 1941 until 1968 it was
illegal to practise herbal medicine without a medical qualification.
THE TIDE TURNS
Although there were spectacular successes with modern chemical medicines, there were also horrific
disasters, most notably the thalidomide tragedy in 1962 in Britain and Germany, when 3,000
deformed babies were born to mothers who had taken the drug thalidomide as a sedative during
pregnancy. This event marked a turning point in the public’s opinion of chemical medicines. People
began to realize that a serious cost could accompany the so called benefits attributed to modern
pharmaceutical drugs. This, and the factors described below, have brought about a massive change in
public perceptions of the value of herbal medicine.
THE CHINESE EXAMPLE
Herbal medicine experienced a major gain in fortune in 1949 in China, when Mao Zedong and the
Communist Red Army gained control of the country. Though traditional Western medicine by that
time was well established in China most of the population had little hope of access to modern
hospitals, let alone to new drugs. Out of necessity, traditional Chinese medicine essentially herbal
medicine and acupuncture, once more began to be used alongside Western conventional medicine.
The authorities aimed to provide the best of both worlds. Five teaching hospitals for traditional
Chinese medicine were established, where it was taught on a scientific basis. In addition, great
efforts were made to improve the quality of plant medicines.
Contrary to the trend in conventional Western medicine that makes the patient ever more dependent
upon the doctor and high-tech machinery, TMC, like other forms of complementary medicine,
stresses the patient’s personal responsibility for his or her own cure, encouraging a holistic approach
to treatment.
In the 1960s, China also established a system of “barefoot doctors”. After a period of basic medical
instruction that blended herbal medicine, acupuncture and Western practices, these practitioners were
sent out to provide health care for the millions of rural Chinese too remote from cities to benefit from
the facilities available there. The barefoot doctors in the late 1960s became a model for the World
Health Organization, which created a strategy of including traditional herbal practitioners in planning
for the health care needs of developing countries.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 14
WESTERN MEDICINE & HERBAL PRACTICES
Further to the initiative by the World Health Organization, experience has shown that traditional
[usually herbal] and Western medicine can indeed work well in tandem, although the relationship is
often quite complex. M. Janzen’s The Quest for Therapy in Lower Zaire [University of California
Press, 1978] describes one such interaction in Africa:
“The people of Zaire recognize the advantages of Western medicine and seek its surgery,
drugs and hospital care, but contrary to what might have been expected, native doctors,
prophets, and traditional consultations among kinsmen do not disappear with the adoption of
Western medicine. Rather a working relationship has developed in which different forms of
therapy play complementary rather than competitive roles in the thoughts and lives of the
people.”
The high cost of Western medical treatment is another factor that has encouraged people and
governments to re-examine traditional healing. In China, Mexico, Cuba, Egypt, Ghana, India and
Mongolia, to give but a few examples, herbal medicines are being cultivated in greater quantities,
and are being used to some degree by conventional as well as traditional practitioners. Likewise,
different types of treatment have evolved to meet the variety of needs within a population. India
offers an extraordinary example of the kind of choices available in types of medical care. Alongside
physicians trained in conventional Western medicine, there are medically trained Ayurvedic
practitioners, traditional Ayurvedic practitioners, local healers and homeopaths.
CHANGING ATTITUDES
Perhaps the most important factor behind the growing interest in complementary medicine is the
poor state of health in Western societies. Conventional medicine has by and large brought serious
infectious diseases under control, although there are worrying signs that infectious organisms are
becoming resistant to antibiotic treatment, largely as a result of their indiscriminate use. Chronic
illness, however, seems to be on the increase. Probably around 50 per cent of people in Western
countries daily take one or more conventional medicines - for conditions as diverse as high blood
pressure, asthma, arthritis and depression. Many Western countries such as the US and France spend
astronomical sums on health care, yet despite this massive investment much of the population
remains demonstrably unhealthy. Even the significant increase in life expectancy in developed
countries is starting to go into reverse, perhaps as a result of environmental pollutants and toxic
accumulation within the body.
Over the years, changes in public awareness have led to a renewed interest in herbal medicine. In
fact, some herbal preparations are now so commonly used that they are accepted as a part of
everyday life. One of many possible examples is evening primrose oil, which is used by hundreds of
thousands of women in Britain to help relieve pre-menstrual tension. It is extracted from the seeds of
a North American plant. Peppermint oil, prescribed for irritable bowel syndrome and other gut
problems, is another example, while senna, a simple, effective treatment for short-term constipation,
is one of the most frequently used medicines throughout the world.
The growing awareness of how our lives as human beings are interwoven with the fate of our planet
also reinforces the value of herbal medicines. As long as care is taken to prevent over-harvesting,
herbal medicine is ecologically in tune with the environment.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 15
HERBALISM & HOLISM
The “germ theory of disease”, which holds that illness springs from contact with an infectious
organism, is still widely held in conventional medicine. Medical herbalists however believe that this
is only part of the picture. While illnesses such as cholera and typhoid are highly infectious and are
indeed likely to be caught by almost anyone, many infectious diseases are not transmitted
automatically from one person to another, The question that arises therefore is what weakness within
the patient has allowed the “seed” of infection to find fertile ground? Unlike conventional medical
practice, which focuses on eradicating the “bug” or abnormal condition, herbal medicine has a more
balanced approach, seeking to treat the weakness that gave rise to ill health, and setting this in the
context of the patient’s life as a whole. Herbalists identify a variety of factors behind the onset of
illness. While bodily signs and symptoms are the most important indicators, dietary emotional and
even spiritual factors are also taken into account.
Our bodies contain over three trillion cells, which collectively must function in harmony if good
health is to be maintained. Used wisely, herbs work in tune with our bodies, stimulating, supporting
or restraining different sets of cells in their allotted tasks within the body and encouraging a return to
normal balanced function. Remedies intended to strengthen the patient’s own resistance, improve the
vitality of weakened tissue, and encourage the body’s innate ability to return to good health.
Of course, for people with severe acute illnesses it may be too late to use a herbal approach to
treatment. In these circumstances, strong-acting conventional medicines such as heart drugs,
antibiotics and painkillers, as well as surgery can all be life—savers. However, a health—care
system that is carefully attuned to the needs of the patient might well provide herbal remedies as a
first line of treatment, with conventional medicines held in reserve to be used only when necessary
EVIDENCE IN SUPPORT OF HERBAL CURES
Many medical scientists have found it impossible to accept that natural medicines can be as good as
or better than chemical cures in treating illness. Fortunately as more and more research reveals just
how effective herbal medicines can be, this attitude is beginning to change.
St John’s Wort is a native European herb, valued for its healing properties. In his Herbal in 1597,
John Gerard commends the oil as “a most pretious remedie for deep wounds and those that are
thorow the body for the deep sinuses that are prickt, or any wound made with a venomed weapon… I
know that in the world there is not a better [italics added]”. Four centuries later, in a contemporary
trial, St John’s Wort was shown to be powerfully anti-viral, offering up hope that it may be valuable
in the treatment of many conditions, including HIV and AIDS.
St John’s Wort is also a time-honoured remedy for mild depression and nervous exhaustion. A 1993
hospital-based research study in Austria showed that it is every bit as effective as conventional
treatments, and unlike many of, them has a very low incidence of side effects.
St John’s Wort is an example of how modern research often confirms what herbal practitioners have
known for centuries. Today’s practitioners, however, have one important advantage – the method by
which the plant works within the body is now better understood, so that it is possible to be precise
about dosages, aware of possible side-effects, and confident in what form the herb should be taken as
a medicine.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 16
In addition to St John’s Wort, many other herbs are being investigated in the search for effective
treatments for HIV and AIDS. To give but two examples, the Australian Moreton Bay chestnut,
which was used by the Aborigines as an arrow poison, and the Japanese white pine are both currently
being researched. We can expect to see a dramatic increase in the number of herbs being investigated
for medicinal use in the near future.
MEDICINAL HERBS & BIG BUSINESS
The major pharmaceutical companies have realized that rainforests, grasslands and even hedgerows
and fields are sources of potentially invaluable medicines. As a result, they are investing large sums
to try to find new plant chemicals that can be marketed as medicines. Glaxo, arguably the largest
pharmaceutical company in the world, trawls 13,000 plant chemicals a week searching for
potentially useful constituents. It is in the process of automating its research in this area and will
shortly have the capacity to investigate around two million plant chemicals a week.
If this is a taste of what is to come, we can expect remarkable discoveries from the world of plant
medicine. There is, however, a key problem in the pharmaceutical industry’s approach. It is geared to
the development of isolated plant chemicals which can then be synthesized and patented. With a
patent, a company can make a profit, recouping the massive investment required to research and
develop new medicines. Herbs, however, are whole, naturally occurring remedies. They cannot and,
in the authors opinion, should not be patented or be even patentable. Even if the major
pharmaceutical companies were able to find a herb such as St John’s Wort, which proved to be more
effective and safer than conventional medicines, they would prefer to develop synthetic chemical
drugs rather than plant medicines.
HERBAL SYNERGY
One word more than any other separates herbal from conventional medicine: synergy. When the
whole plant is used rather than extracted constituents, the different parts interact, often, it is thought,
producing a greater therapeutic effect than the equivalent dosage of isolated active constituents that
are generally preferred in conventional medicine.
Increasingly research shows that herbs such as ephedra, hawthorn, ginkgo and lily of the valley have
a greater-than expected medicinal benefit thanks to the natural combination of constituents within the
whole plant. In some cases, the medicinal value of the herb may be due entirely to the combination
of substances and cannot be reproduced by one or two “active” constituents alone.
THE FUTURE OF HERBAL MEDICINE
The main issue for the future of herbal medicine is whether medicinal plants, and the traditional
knowledge that informs their use, will be valued for what they are – an immense resource of safe,
economical, ecologically balanced medicines – or whether they will be yet another area of life to be
exploited for short-term profit.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 17
Another issue is convincing sceptics in the medical world that herbal medicine is not just a poor
substitute for conventional medicine but a valuable form of treatment in its own right. In trials into
the effect of certain Chinese herbs on patients with eczema at London’s Royal Free Hospital in the
early 1990s, conventional specialists were astonished when the addition of one extra herb to a
Chinese formula containing 10 others resulted in a dramatic improvement in a previously
unresponsive patient. This story offers evidence of the skill and art involved in herbal practice. In
tailoring the remedy to suit the individual needs of the patient and in treating the underlying cause,
major improvements were made. This kind of approach is a far cry from the standard medical view
of using a single drug to treat a single disease.
In India and China, there have been university courses in herbal medicine for decades. In the West
this process has been slower, although the first undergraduate course in herbal medicine in Western
Europe started at Middlesex University in London in 1994. In its combination of traditional herbal
knowledge and the medical sciences, it parallels large-scale developments in China, and points
towards a future where patients might be able to choose between conventional and herbal approaches
when considering what medical treatment will suit them best.
THE DEVELOPMENT OF HERBAL MEDICINE
EUROPE
Despite regional variations, European herbal practices largely arose from the common root of the
classical tradition. Today, herbalism is increasingly popular in Europe, and in some countries it is
widely practised by orthodox medical practitioners as well as by qualified herbalists.
Each of the World’s major herbal traditions has developed its own framework for making sense of
illness. In Europe, the model for understanding and explaining illness was the “theory of the four
humours”, which persisted well into the 17th century. It was laid down by Galen AD 131-201,
physician to the Roman emperor Marcus Aurelius. Galen was born in Pergamuni and part of his
medical practice involved caring for the gladiators of the city; which gave him the opportunity to
learn about anatomy and the remedies best suited to healing wounds. He wrote literally hundreds of
books and his influence on European conventional and herbal medicine has been immense. To this
day, plant medicines are sometimes called Galenicals to distinguish them from synthesized drugs.
THE THEORY OF THE FOUR HUMOURS
Galen developed his ideas from the texts of Hippocrates 460-377 BC and Aristotle 384-322 BC, who
in turn had been influenced by Egyptian and Indian ideas. Hippocrates, expanding on the early belief
that the world was made up of the elements fire, air, earth and water, classified herbs as having hot,
dry, cold and moist properties. Aristotle developed and endorsed the theory of the four humours.
According to the theory, four principal fluids or humours exist within the body: blood, choler
[yellow bile], melancholy [black bile] and phlegm. The “ideal” person bore all four in equal
proportion. However, in most people, one or more humours predominate, giving rise to a particular
temperament or character. For instance, excess choler would produce a choleric-type person who
was likely to be short-tempered, sallow, ambitious and vengeful. Galen also believed that pneuma
[spirit] was taken in with each breath, and processed in the body to form the “vital spirit”. Vitality
and health depended upon the proper balance between the four humours and the four elements and
the correct mix with the inspired pueunla.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 18
INFLUENCE OF CLASSICAL HERBALISTS
Two other classical writers strongly influenced the European herbal tradition. Dioscorides AD 40-90,
a Greek-born Roman army surgeon, wrote the classical world’s most comprehensive book on herbal
medicines, De Materia Medica, based on observations of nearly 600 plants. Pliny the Elder 23-79
AD drew together writings from over 400 authors in his Natural History, recording, amongst other
things, herbal lore of the time. Much traditional European knowledge of medicinal herbs comes from
Dioscorides and Pliny. One of the most interesting herbs mentioned by both is mandrake. With a
forked root that resembles the human shape, mandrake was credited with great magical and healing
powers. It was an herb that was recommended by Dioscorides for many ailments, including
sleeplessness and inflammation of the eyes.
With the collapse of the Roman Empire in the 4th century AD, the debate about how illness arose and
how it should be treated shifted to the East. By the 9th century, Islamic physicians had translated
much of Galen’s work into Arabic, and his ideas affected the development of Arabic medicine into
the Middle Ages, influencing Avicenna 980-1037. Later in the Middle Ages, Galen’s writings were
translated back into Latin from the Arabic and, for 400 years, his ideas held sway and were diligently
applied in European medical practice. Even in the 16th and 17th centuries, students in university
medical schools were given an academic training in the principles of the humoural system, as
established by Galen. They learnt how to diagnose an imbalance of the humours, and the methods of
restoring equilibrium, primarily bloodletting and purging.
PRINTING & HERBAL MEDICINE
The invention of printing in the 15th century changed the face of herbal medicine in Europe. Before
that time, European folk medicine had been handed down from generation to generation. While some
early herbals were written in Anglo-Saxon, Icelandic and Welsh, for example, for the most part the
tradition was orally based.
During the following centuries, herbals were published throughout Europe in different languages,
making standardized catalogues of herbs and their applications accessible to the general public and
not just to those who understood Latin. As literacy rates rose, women in particular used in some
cases the printed herbals written by physicians largely reflected the writings of classical authors such
as Dioscorides. In other instances they were based directly on first-hand experience the English
herbals of John Gerard 1597 and Nicholas Culpeper 1652 being good examples.
John Gerard’s ‘The Herbal’ is clearly the work of a horticulturist, rather than of a herbal practitioner,
but is nonetheless a mine of information. The book includes many plants that had been recently
brought back to Europe by explorers and traders. Culpeper’s ‘The English Physicians’ has been
widely used as a practical reference book ever since its publication. It is a rich blend of personal and
practical experience of traditional European medicine and astrological thought. Each herb is assigned
a “temperature”, a use within the humoural system, a ruling planet and a star sign. Like Dioscorides’
De Materia Medica it has the merit of being based on close observation and extensive experience in
the use of herbal medicines.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 19
FOREIGN HERBS & SYNTHESIZED DRUGS
The growing use of foreign herbs in the 17th century prompted heated debate about the relative value
of indigenous European herbs, but for the majority of the population this was irrelevant as the
imported herbs were well out of their price range. In the end, it created a rift in herbal medicine. Poor
and rural peoples used locally available herbs, while affluent city-dwellers and aristocrats purchased
plants of foreign origin, prescribed by university-trained physicians.
By the beginning of the 18th century approximately 70 per cent of plant medicines stocked by
European apothecaries were imported. Over time, this city-based herbalism evolved into
conventional scientific medicine, which in turn rejected its herbal roots and regarded plant medicines
as inferior.
Once conventional medicine established its monopoly of practice in most European countries by the
end of the 19th century it became (and in many cases remains) illegal to practise herbalism without
medical certification. In Greece, traditional herbalists, known as komboyannites, were persecuted,
and the word itself became an insult meaning “trickster” or “quack”. In France and Italy experienced
traditional herbalists were imprisoned for providing treatment to their patients. The renaissance in
herbal medicine that has occurred in the last 25 years offers hope that official censure will change.
MODERN PRACTITIONERS
The pattern of herbal medicine across Europe today is remarkably varied, but a common thread runs
through the different traditions and practices. Most European herbalists use orthodox methods of
diagnosis, looking for signs of infection and inflammation, for example. However, most also try to
establish a broad, holistic picture, placing the illness in the context of health and what has caused the
body to become diseased. The cause is important for if the cause is taken away the body will heal
itself given a little natural help! Healers in medieval Europe frequently sought to restore physical
imbalance with bloodletting, purges and preparations that caused vomiting.
POPULAR HERBS
In European herbal medicine, native herbs are still highly popular. Alpine plants such as arnica and
pasque flower are much used in Swiss, German, Italian and French herbal medicine, while comfrey
is particularly well liked in Britain. There has also been a surge in demand for exotic herbs. The
Chinese ginkgo tree, which improves circulation of blood to the head and helps the memory, is now
cultivated in vast plantations in France, and became the best-selling medicine of all in Germany in
1992.
EUROPEAN TRADITIONS & THE FUTURE
Sales of over-the-counter herbal medicines in Europe are increasing at a dramatic rate. In the UK
between 1990 and 1995, sales climbed by 25%. Herbal medicine or “phytotherapy” is so esteemed in
Germany that conventionally trained doctors routinely prescribe herbs along with orthodox drugs. In
contrast, herbalism in the UK is practised by those who have trained in herbal rather than
conventional medical schools, providing treatment that is complementary to conventional medicine.
The picture is again different in Spain. Some doctors prescribe herbal medicines, but traditional
herbalists, still practise. They learn by apprenticeship, gathering herbs from the wild and preparing
their own medicines.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 20
How the European Union will manage to legislate the safe practice of each of these three types of
herbalism remains to be seen, but each has a significant contribution to make in a future in which
people hopefully will be free to choose the treatment that accord with their ideas and wishes. THE
LAST lesson of this course will hopefully include much of the new laws, though as it is ongoing
John Gerard’s 1597 Herbal is one of the classic texts on healing plants.
INDIA
In India and the surrounding regions, Ayurvedic medicine is the dominant herbal tradition. It is
thought to be the oldest system of healing in the world, predating even Chinese medicine. Today the
government, as an alternative to conventional medicine, actively promotes it. A lesson is devoted to
this system of medicine later in the course also the Chinese system.
The name Ayurveda derives from two Indian words: ayur, meaning life and veda, meaning
knowledge or science. Ayurvedic medicine is more than a system of healing. It is a way of life
encompassing science, religion and philosophy that enhances well-being, increases longevity and
ultimately brings self-realization. It aims to bring about a union of physical, emotional and spiritual
health, known as swasthya. This state enables the individual to enter into a harmonious relationship
with cosmic consciousness.
EARLY ORIGINS
Ayurveda evolved over 5,000 years ago in the far reaches of the Himalayas from the deep wisdom of
spiritually enlightened prophets, or rishis. Their wisdom was transmitted orally from teacher to
disciple, and eventually set down in Sanskrit poetry known as the Vedas.These writings, dating to
approximately 1500 BC, distilled the prevailing historical, religious, philosophical and medical
knowledge, and form the basis of Indian culture. The most important of these texts are the Rig Veda
and the Atharva Veda.
In about 800 BC, the first Ayurvedic medical school was founded by Punarvasu Atreya. He and his
pupils recorded medical knowledge in treatises that would in turn influence Charaka, a scholar who
lived and taught around 700 BC. His writings, the Charaka Samhita, describe 1,500 plants,
identifying 350 as valuable medicines. This major reference text is still consulted by Ayurvedic
practitioners. The second major work was the Susruta Sam hita, written a century later, which forms
the basis of modern surgery and is still consulted today.
THE INFLUENCE OF AYURVEDA
Other systems of medicine such as the Chinese, Tibetan and Islamic [Unani Tibb] traditions have
their roots in Ayurveda. For example, the Buddha [born c. 550 BC] was a follower of Ayurveda, and
the spread of Buddhism into Tibet during the following centuries was accompanied by increased
practice of Ayurveda.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 21
The ancient civilizations were linked to one another by trade routes, campaigns and wars. Arab
traders spread knowledge of Indian plants and Arab physicians studied Ayurvedic medicine, cloves
for instance are said to have been used medicinally for thousands of years in India. Ayurvedic
included Indian plants in their materia medica. The flower buds are dried in the open air. This
knowledge was passed on to the ancient Greeks and Romans, whose practices were eventually to
form the basis of European medicine.
THE FIVE ELEMENTS
Ayurveda is a unique holistic system, based on the interaction of body, mind and spirit. In Ayurveda,
the origin of all aspects of existence is pure intellect or consciousness. Energy and matter are one.
Energy is manifested in five elements – ether, air, fire, water and earth – which together form the
basis of all matter. In the body, ether is present in the cavities of the mouth, abdomen, digestive tract,
thorax and lungs. Air is manifested in the movements of the muscles, pulsations of the heart,
expansion and contraction of the lungs, and the workings of the digestive tract and the nervous
system. Fire is manifested in the digestive system, metabolism, body temperature, vision and
intelligence. Water is present in the digestive juices, salivary glands, mucous membranes, blood and
cytoplasm. Earth exists in the nails, skin and hair, as well as in the elements that hold the body
together: bones, cartilage, muscles and tendons.
The five elements manifest in the functioning of the five senses, and they are closely related to our
ability to perceive and interact with the environment in which we live. In Ayurveda, ether, air, fire,
water and earth correspond to hearing, touch, vision, taste and smell respectively.
THE DOSHAS & HEALTH
The five elements combine to form three basic forces, known as the tridoshas, which exist in
everything in the universe and influence all mental and physical processes. From ether and air, the air
principle vata is created; fire and water yield the fire principle pitta; and earth and water produce the
water principle kaplia. The principles correspond closely to the three humours of Tibetan medicine
and somewhat resemble Galen’s theory of the four humours.
According to Ayurveda, we are all born with a particular balance of dashos. The proportions are
largely determined by the balance of doshas in our parents at the time of our conception. Our body
type, temperament, and susceptibility to illnesses are largely governed by the predominant dosha. In
this way we inherit our basic constitution, called the pro ken ti, which remains unaltered throughout
our lives.
The first requirement for health in Ayurveda is a proper balance of the doshas. If the balance is upset,
illness, ryadhi, results. The disruption may be manifested in physical discomfort and pain, or in
mental and emotional suffering, including jealousy, anger, fear and sorrow. While our balance of
doshas influences vulnerability to certain kinds of illness, the principles do not work in a vacuum.
India’s medical system, Ayurveda, identifies seven energy centres, chakras, sited along the spinal
column from the head to the base of the spine. If they are blocked, illness results.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 22
THE DEVELOPMENT OF HERBAL MEDICINE
Our lifestyle has a strong effect upon overall health, and it may easily disrupt its balance. Illness may
also result if the flow of energy, prana, around the body is interrupted. The flow is relayed via the
seven chakras (psychic energy centres), which are situated at various points along the spinal column,
from the crown of the head to the tailbone. If the energy flowing between these centres is blocked,
the likelihood of ill health increases.
VISITING AN AYURVEDIC PRACTITIONER
An Ayurvedic practitioner first carefully assesses prakruti and vakruti —constitution and lifestyle.
This involves taking a detailed case history and carefully examining the patients body, paying
particular attention to the bodies build, the lines in the face, the hands, the skin and the hair type – all
of which point to more profound aspects of the patient’s condition. However, the main foundations
on which diagnosis rests are the appearance of the tongue, and the patients pulse rate. In these
respects, Ayurveda has much in common with Chinese and Tibetan medicine, in which these two
indicators are also of the greatest importance. A very complex technique for taking the patient’s
pulse has been developed by Ayurvedic practitioners, requiring many years’ experience.
When a dosha imbalance has been diagnosed, medical treatment and lifestyle advice are provided.
The first step is eliminating toxins and the main cleansing and rejuvenation programme, known as
pancho karma, includes therapeutic vomiting, purging, enemas, and nasal administration of
medication and purification of the blood.
ATTRIBUTES OF REMEDIES
Subsequent treatments fall into three main categories: medicines from natural sources, dietary
regimes, and behavioural modifications. Medicines, foods and lifestyle activities are all classified
according to their effect on the three doshas. For instance, a health problem associated with an excess
of kapha, the water principle, is characterized by catarrh, excess weight, fluid retention and lethargy.
The practitioner would prescribe the consumption of warm, dry, light foods, because the quality of
kapha is cool and damp. Avoidance of cold damp foods (such as wheat, sugar and milk products),
which increase kapha, would also be advised. Herbal remedies would include warming spices such
as ginger, cinnamon and cayenne, as well as bitters such as turmeric and aloe vera.
The specific choice of herbal remedy depends on its “quality” or “energy”, which Ayurveda
determines according to twenty attributes (vimshati guna) such as hot, cold, wet, dry, heavy or light.
Ayurveda also classifies remedies according to six tastes – sweet, sour, salty, bitter, pungent and
astringent. Sweet, sour and salty substances increase water [kapha] and decrease air [va to]; bitter,
pungent and astringent remedies increase air and decrease water; and sour, salty and pungent herbs
increase fire [pitta].
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 23
PREPARATIONS & TREATMENTS
In addition to plant extracts, Ayurvedic medicines include honey and dairy produce, and sometimes
minute doses of minerals such as salt are added. Remedies take the form of pills; powders, balms and
infusions, and most contain several different ingredients, all carefully balanced to the individuals
needs. Treatment might include washes and enemas or the application of poultices as well as
massage with warm herbal oil, burning incense, the use of precious stones and metals, and ritual
purification for imbalanced mind and emotions. The chanting of mantras [incantations based on
sacred texts], breathing and meditation exercises may be advised, due to the power of sound and the
effect of vibration and meditation on the body, mind and spirit.
THE VALUE OF AYURVEDIC MEDICINE
The importance of Ayurveda is proved in part by its timelessness, since it has existed as an unbroken
tradition for thousands of years. This is despite a number of obstacles. Following the rise of the
Mogul empire in the 16th century the dominance of Islamic medicine, Unani Tibb, led to the partial
repression of Ayurveda in India. In the 19th century, the British dismissed it as nothing more than
native superstition and in 1833 they closed all Ayurvedic schools and banned the practice. Great
centres of Indian learning thus fell apart, and Ayurvedic knowledge retreated into villages and
temples. At the turn of the century, however, some Indian physicians and enlightened Englishmen
began to re-evaluate Ayurveda, and by the time India became independent in 1947 it had regained its
reputation as a valid medical system. Today, Ayurveda flourishes side by side with Unani Tibb and
Western conventional medicine and is actively encouraged by the Indian government as an
inexpensive alternative to Western drugs. In recent years, Ayurveda has attracted increasing attention
from medical scientists in the West and in Japan, and the World Health Organization has resolved to
promote its practice in developing countries.
Ayurveda’s value lies in the fact that it is not a medical science that deals solely with the treatment of
disease. Instead, it offers practical guidelines for living, which are applicable to every facet of daily
existence. It also seeks to reconcile health and lifestyle with the universal aspects of existence, and
thus it enhances the well-being, longevity and harmony of all those who practise it. For these
reasons, Ayurveda is of lasting benefit to anyone seeking an alternative to traditional Western
practices.
CHINA
China’s ancient herbal tradition has survived intact into the 20th century and in China it is accorded
equal status with Western conventional medicine. Many Chinese universities now teach and research
herbal medicine, a factor of crucial importance in the re-emergence of herbalism worldwide.
Traditional Chinese medicine TMC and the herbal tradition that is part of it developed separately
from Chinese folk medicine. It arose from ideas recorded between 200 BC and AD 100 in the
Yellow Emperor Classic of Internal Medicine [Huang Di Nei Jing]. This text is based on detailed
observations of nature and a deep understanding of the way that all life is subject to natural laws. It
contains concepts that are fundamental to TMC, including yin and yang; the five elements (wu xing);
and the theory of the effect of nature upon health.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 24
In TMC, living in harmony with these principles is the key to good health and longevity. According
to the Yellow Emperors Classic, members of previous generations lived for a hundred years, and had
constitutions so strong that illness was cured by incantations alone. Only later, as human vitality, or
chi, declined and people became “overactive… going against the joy of life”, did herbal medicine,
acupuncture and other branches of TMC become necessary.
Unlike other herbal traditions that have a unified theory for making sense of illness and disease (for
example, the European theory of the four humours), TMC has two quite different systems the yin and
yang theory and the theory of the five elements. They developed quite separately in China and the
five elements system was only accepted and fully incorporated into Chinese medicine during the
Song dynasty.
The ancient five elements theory is used by the Chinese when writing prescriptions. It associates
herbs with the natural world, including seasons and parts of the body. In the circular movement, each
element gives rise to the next for example, winter gives rise to spring. The five-angled movement is a
control, in which each element restrains another.
960-1279 AD – To this day, differences between the ‘above discussed’ theories are reflected in
practitioners’ approaches to diagnosis and treatment.
In Chinese thought, everything in the universe is composed of yin and yang - words that were first
used to denote the dark and light side of a valley. Everything has yin and yang aspects, or
complementary opposites - such as day and night, up and down, wet and dry. Every yin or yang
category can itself also be subdivided - so that while the front of the body is yin relative to the back,
which is yang, the abdomen is yin relative to the chest, which is yang.
The five elements theory associates constituents of the natural world – wood, fire, earth, metal and
water – with other fundamentals such as the seasons, emotions and parts of the body. Each element
gives rise to the next in a perpetual fashion. For this reason, the system might be more accurately
described as the five phases, representing the process of continual movement in life. The five
elements have a central role in Chinese herbal medicine, especially in the grouping of tastes of herbs
and parts of the body.
DIAGNOSIS & TREATMENT
Instead of looking for causes of illness, Chinese practitioners seek patterns of disharmony, which are
expressions of imbalance between yin and yang. Particular attention is given to reading the pulse and
tongue, both of which are very important for an accurate diagnosis. Ill health results from a
deficiency or excess of either yin or yang. A cold, for example, is not just the result of a virus
(though this clearly is a cause), but a sign that the body is not adapting to external factors such as
“wind-heat” “wind-cold” or “summer-heat”.
DEVELOPMENT OF HERBAL MEDICINE
A high temperature denotes too much yang and shivering is the result of an excess of yin. The art of
the Chinese herbal practitioner is to restore harmony between yin and yang both within the patient’s
body and between the patient and the world at large.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 25
CHINESE HERBS
Over the centuries, the number of medicinal herbs has grown and the 1977 Encyclopaedia of
Traditional Chinese Medicinal Substances has 5,757 entries, the majority of which are herbs. The
Communist Revolution in 1949-helped swell the number of plants used in TCM, because herbs that
had previously only been employed in folk medicine were incorporated into traditional medicine.
As the herbal tradition developed within TMC, the taste and other characteristics of herbs became
closely linked with their therapeutic uses. The Divine Husbandman Classic 1st century AD lists 252
herbal medicines specifying their tastes and “temperatures”, and today, Chinese herbalists still relate
the taste and temperature of a herb directly to its therapeutic use. Sweet-tasting herbs such as ginseng
are prescribed to tone, because they harmonize and moisten, while bitter-tasting herbs such as dan
sheii are employed to drain remedy and dry excess “dampness”. Hot-tasting herbs are used for
treating “cold” conditions and vice versa. Together, a herb’s taste and temperature link it to specific
types of illness. For example, Baical skullcap that is bitter-tasting and “cold”, is a drying, cooling
herb that is recommended for conditions such as fever and irritability, brought on by patterns of
excess heat.
TAKING MEDICINES
The Chinese tradition relies heavily on formulae, which are set mixtures of herbs that have proven
effectiveness as tonics or remedies for specific illnesses. Many are available over the counter and are
used by millions of people every day in China and around the world. Chinese herbalists often take a
formula as a starting point and then add other herbs to the mixture, There are hundreds of formulae,
one of the most famous being “Four Things Soup”, a tonic given to regulate the menstrual cycle and
tone the reproductive system. It consists of Chinese angelica, rehmannia, chuang xiong and white
peony.
Chinese herbal medicine uses tinctures or alcoholic extracts of herbs, but only infrequently.
Generally, patients are given mixtures of roots and bark to take as decoctions two or three times a
day.
THE CHINESE INFLUENCE IN JAPAN & KOREA
Japan and Korea have been strongly influenced by Chinese medical ideas and practices. Traditional
Japanese medicine traces its origins back to the 5th century AD, when Buddhist monks from Korea
introduced their healing arts, largely derived from Chinese medicine into Japan. In the following
century, the Empress Suiko 592-628 AD sent envoys to China to study that country’s culture and
medicine. Direct Chinese influence on Japanese medicine, which was practised for the most part by
the monks, continued for 1,000 years. In the 16th century, Japan started to assert its cultural identity
and kampoh developed its own characteristic traits, emphasizing the Japanese ideals of simplicity
and naturalness. However, certain Chinese concepts, such as yin and yang and ki chi continued to
have a central role.
In 1868, the Japanese embraced Western conventional medicine. Formal training in traditional
Japanese medicine officially ceased in 1885, but a few committed practitioners passed their
knowledge on to younger generations, keeping the tradition alive. In the last 20 years the number of
practitioners has greatly increased, and kampoh is currently taught at Toyama University in Honsu.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 26
Korean herbal medicine is very similar to mainstream Chinese herbal medicine, and almost all the
Chinese herbs are used in Korea. Ginseng has been cultivated in Korea for home use and export
since 1300.
IMPORTANCE OF CHINESE HERBAL MEDICINE
Since 1949 when the Communists gained control, the herbal tradition has flourished in China and
today it is recognized as a valid medical system, available to the Chinese on an equal footing with
conventional Western medicine. As is often the case elsewhere, herbs seem to be used mainly for
chronic conditions, while Western medicine is more frequently employed for serious acute illness.
Chinese herbal medicine, however, is not just of significance in China and the surrounding regions.
Many Chinese universities now teach and research herbal medicine, and this development, and the
massive input of resources involved, has helped revitalize herbalism worldwide during the last 20-30
years.
Chinese herbal medicine is now practised by trained practitioners in every continent and even has
official government recognition in some countries. For example, in 1995, the French government
signed an agreement with the Chinese to establish a hospital in Paris, offering acupuncture and
traditional Chinese herbal medicine. In the same way that ephedra was discovered to be such an
excellent medicine for allergies and asthma, so increasing numbers of Chinese herbs will be found to
have major health benefits, and there is little doubt that over the next few decades Chinese herbal
medicine will continue to grow in popularity around the world.
AFRICA
In Africa there is a greater variety of herbal traditions than in any other continent. During the
colonial period, native herbal practices were largely suppressed, but today in a marked turnaround,
practitioners of conventional medicine often work closely with traditional healers.
The therapeutic use of medicinal plants in Africa dates back to the earliest times. Ancient Egyptian
writings confirm that herbal medicines have been valued in North Africa for millennia. The Ebers
papyrus [c. 1500 BC], one of the oldest surviving medical texts, includes over 870 prescriptions and
formulae, 700 medicinal herbs – including gentian, aloe and opium poppy – and covers conditions
ranging from chest complaints to crocodile bite. The medicinal arts put forward in this and other
Egyptian texts formed the intellectual foundation of classical medical practice in Greece, Rome and
the Arabic world.
TRADE & THE ARABIAN INFLUENCE
Herbal medicines have been traded between the Middle East, India and north-eastern Africa for at
least 3,000 years. Herbs widely used in the Middle East, such as myrrh for example, originally came
from Somalia and the Horn of Africa. From the 5th century AD to the 13th century, Arab physicians
were at the forefront of medical advancement and in the 8th century, the spread of Arabic culture
across northern Africa had an influence on North African medicine that lasts to this day. In the mid-
13th century, the botanist Ibn El Beitar published a Materia Medico that considerably increased the
range of North African plant medicines in common use.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 27
ANCIENT BELIEFS & INDIGENOUS HERBS
In the more remote areas of Africa, nomadic peoples, such as the Berber of Morocco and the
Topnaar of Namibia, have herbal traditions that remain largely unaffected by changes in medicine in
the world at large. For these peoples, healing is linked to a magical world in which spirits influence
illness and death. In Berber culture, possession by a djinn [spirit] is a major cause of sickness, and
herbs with “magical” properties are given to restore health. If the patient fails to recover, their
condition is likely to be attributed to a curse or to the “evil eye”.
The Topnaar formerly depended completely on their environment for medicines, using the few
medicinal plants that grow in such harsh and arid conditions. Although they are now heavily
influenced by the Western way of life and have lost much of their plant lore, they continue to employ
many indigenous plants medicinally. The stem of the seaweed, for example, is roasted, mixed with
petroleum jelly and rubbed into wounds and burns, while Hoodia currori, a low-lying cactus, is
stripped of its thorns and outer skin and eaten raw to treat coughs and colds.
Throughout Africa, thousands of different wild and locally grown medicinal plants are sold in the
markets. Some are prescribed as medicines for home use. Others, such as kanna and iboga, are
chewed to combat fatigue, and are taken as intoxicants in religious ceremonies. According to local
accounts in the Congo and Gabon, iboga’s stimulant effect was discovered when observers saw wild
boars and gorillas dig up and eat the roots, and subsequently become frenzied.
TRADITIONAL & CONVENTIONAL CARE
Conventional Western medicine is well established throughout Africa, but in rural areas, far from
medical and hospital services, traditional medicine remains the only form of health care available.
Even in urban areas conventional health care services can be limited and in this situation, traditional
providers of care such as spiritualists, herbalists and midwives are the main source of treatment
available for the majority of the population. The World Health Organization aimed to achieve a level
of health care by the year 2000 that it is hoped will permit all people to lead socially and
economically productive lives. In an attempt to meet this, African countries have pioneered training
traditional medical practitioners in simple medical techniques and basic hygiene procedures. In one
centre in Ghana, conventionally trained medical staff work hand-in-hand with traditional herbal
practitioners, encouraging the safer use of herbal medicines and researching them in detail. This
represents a remarkable change in attitude. In the 19th and much of the 20th centuries, colonial
governments and Christian missionaries viewed traditional herbalists as witch-doctors practising
black magic whose treatments and herbal remedies were best suppressed.
THE DISCOVERY OF NEW HERBAL CURES
Along with encouraging the safer use of herbal medicines, medical centres are researching their use
in detail. The benefits of pygeum have been conclusively established. This tree, which grows in
Angola, Mozambique, Cameroon and South Africa, was traditionally used in central and southern
Africa to treat urinary problems. Today, it is regularly prescribed in conventional French and Italian
medicine for prostate problems. Of the plants currently under investigation in Africa, two shrubs,
Brideliaferruginea found in eastern and western grasslands and Indigofera arrecta found in tropical
areas, show promise in the treatment of diabetes.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 28
The re-evaluation of traditional herbal medicine in Africa may result in the acceptance of additional
plant-based medicines. Today, the opportunity exists to combine the best of traditional practice with
conventional medical knowledge, for mutual gain.
AUSTRALIA
Regrettably, much of the herbal knowledge of the Australian Aborigines was lost after the arrival of
the Europeans. The predominant strains of Australian herbalism today derive from the West, China
and, increasingly from other countries on the Pacific Rim.
The cradle of the oldest continuous culture on earth, Australia is also the home of an ancient herbal
tradition. The Aborigines, believed to have settled in Australia over 60,000 years ago, developed a
sophisticated empirical understanding of indigenous plants, many of which, such as eucalyptus, are
unique to Australia. While much of this knowledge has vanished with its keepers, there is currently a
high level of interest in native herbal traditions.
ABORIGINAL HERBAL MEDICINE
The Aborigines probably had a more robust health than the early European settlers who displaced
them; they had very different ideas of health, disease and illness, in which the influence of the spirit
world played a major role. In common with other hunter-gatherer societies, the Aborigines devoted
much time to ritual, which reinforced the sense of place and purpose in the lives of each individual.
They used healing plants and the laying on of hands in a complex weave of culture and medicine.
The influx of Europeans in the 18th century was disastrous for the Aborigines. They were exploited
and driven off the land, and their population was decimated by killings and by infectious Western
diseases for which they had no immunity. Not only did the Europeans fail to discern any value in
native customs but also much of the orally-based herbal tradition was lost through death of the elders
and the dispersal of tribal groupings.
Nevertheless, a little is known of Aboriginal medicine. Aromatic herbs, such as eucalyptus, were
often crushed and inhaled to treat many common illnesses, including respiratory diseases such as flu.
Without metal technology, water could not be boiled, but decoctions were made by heating water
with hot stones. These decoctions were drunk or applied externally. It is known that skin eruptions,
such as boils and scabies, were common and that they were treated with acacia, while acute diarrhoea
was treated with eucalyptus or kino. In Queensland, fever bark, also called Australian quinine, was
used to treat fevers.
INDIGENOUS & FOREIGN HERBS
Over the last 200 years, many native Australian plants have become popular around the world.
Research into fever bark resulted in the discovery of the alkaloid reserpine, which markedly lowers
blood pressure. The substance is now prescribed by herbalists and conventional practitioners alike.
Eucalyptus and tea tree yield essential oils that are employed worldwide as antiseptics. Other native
Australian plants are now used in Australian herbalism because of their medicinal use elsewhere, for
example gotu kola and visnaga, which have a long history of medicinal use in India and the Middle
East.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 29
Early British settlers imported European medicinal plants, such as vervain, hawthorn, mullein and
dandelion, which have now all become naturalized. Native American plants have also found their
way to Australia, including prickly pear and Canadian fleabane. As Australian herbalists generally
follow the Anglo-American herbal tradition, these plants are often employed in local practice.
CHINESE INFLUENCE
Traditional Chinese medicine has substantially influenced herbalism in Australia. Following the
arrival of Chinese immigrants in the 19th century, herbal formulae gained a reputation for
effectiveness and Chinese medicine maintained a small but loyal following in all the major cities.
During the 1980s, a renaissance in all branches of herbal medicine began, and today Australia has
three colleges of traditional Chinese medicine. Chinese herbs are also quite frequently used by
Australian herbalists, and Chinese patent medicines are widely available in health food shops.
THE FUTURE
Australia is the centre of growing interest in Indonesian, New Zealand and Ayurvedic medicines.
The potential of many native herbs is also being explored – the most notable example being the
Moreton Bay chestnut tree, one of the many plant medicines with potential in treating AIDS.
Commercial cultivation of medicinal plants is expanding, with herbs such as tea tree and opium
poppy becoming major crops. In Tasmania, trials are now under way to try to grow ginseng and
goldenseal, two plants that are very difficult to cultivate.
With its ancient culture and its ties to Western herbalism and location on the Pacific Rim, Australia
is host to many herbal traditions. The next 20 years of Australian herbal medicine should be very
exciting.
THE DEVELOPMENT OF HERBAL MEDICINE NORTH AMERICA
Many ancient herbal traditions in North and Central America not only withstood the influx of
European settlers but also helped to reinvigorate western herbalism. In parts of Central America
herbal medicine is widely practised, and in the US and Canada it is slowly regaining popularity
Stretching from the arctic wild’s of Canada and Alaska to the tropical regions of Panama, North and
Central America covers diverse geographical regions and harbours an immense variety of medicinal
plants. Most of them are indigenous, but others – such as nutmeg, ginger and tamarind – were
introduced from the Old World from the 16th century onwards. Likewise, Native American medicinal
plants – such as corn, cocoa, cayenne and sunflower – were introduced to Europe, Asia and Africa.
This trade of species was an important part of the interplay between the Old and New World’s herbal
traditions.
HERBAL TRADITIONS IN CENTRAL AMERICA
Herbal medicine is commonly practised in rural areas of Central America, especially in Guatemala
and Mexico. In the Mexican tradition, loss of “balance” between hot and cold elements within the
body is thought to be the underlying cause of illness, and the healer’s art is to restore balance and
vitality.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 30
Mexican herbal medicine is not a static tradition, but has evolved from a shifting blend of Aztec,
Mayan and Spanish influence. Long before Hernando Cortez and his conquistadors came ashore in
1519, the Mayan and Aztec cultures had a well-developed understanding of plant medicines. The
Badianus Man the first American herbal written by an Aztec, Martin de la Cruz, in 1552, lists the
medicinal uses of 251 Mexican species. They include damiana, taken by the Maya as an aphrodisiac,
and mesquite, used by the Aztecs as an eye lotion. Both species are still used medicinally, alongside
European herbs such as pennyroyal and thyme. It is thought that approximately 65 per cent of the
plants used by traditional Mexican herbalists originated in Europe.
In other Central American countries efforts are being made to encourage people to use herbal
medicine as the first line of treatment for illness. Projects in the Dominican Republic and Nicaragua,
for example, are teaching women how to use local herbs within their communities while in Cuba
doctors increasingly prescribe medicinal herbs to make up for the scarcity of conventional medicines.
CARIBBEAN HERBAL MEDICINE
Throughout the Caribbean, domestic herbal medicine remains popular. Some of the widely used
herbs include fever grass or lemon grass, which, as its name suggests, is used to treat fevers, and
cerasee, a creeping vine that is prized as a “cure-all” on many of the islands. Cerasee has been shown
to have an ability to lower blood sugar levels and may help to slow down the onset of diabetes, a
relatively common illness among Afro-Caribbeans.
The medical and religious customs on each Caribbean island vary, but on many they reflect the
African traditions of transported slaves, especially of the Yotuba people shipped from West Africa,
who carried on the practices of their homelands. In some of these traditions, herbs are valued for
their magical power as well as for their medicinal properties. Tobacco for example, is used for
divination in many American cultures, including in Santeria and Voodoo religious rituals, as are
other herbs, including garlic and cayenne.
SHAMANISM
Moving north, Native American herbal medicine in what is now the United States was and is
primarily shamanistic in nature, involving herbal lore, ritual and magic. Shamanistic societies from
Siberia to the Amazon believe that, in serious illness, the soul of the sick person has been taken over
by malign forces. The shaman’s role is to heal both the physical and the spiritual dimension of the
illness. The patient cannot be truly cured until his or her soul has been freed from evil spirits.
Shamanistic ceremonies and rites to heal the sick person’s spirit include dancing, chanting,
drumming, playing games, and the stirring of ashes or sprinkling of water. By taking hallucinogens
such as peyote, the shaman is able to reach out to the spirit world and heal both the individual and
the community as a whole.
POWER OF HERBS
In all Native American cultures from Canada to Chile, herbs are thought to have spiritual energy and
many of them are invested with great magical power. The Iroquois believe that cardinal lobelia and
morning glory have the ability to heal or harm, and should be picked, stored and used with great
care. Morning glory is considered so powerful that even touching it could cause harm. The Iroquois
use the plant as a remedy for coughs, tuberculosis and other ailments, and also take it as a decoction
with sunflower seeds as a sacrament in spring and autumn rituals.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 31
Tobacco, now considered an addictive drug, was a sacred shamanistic herb for most Native
American peoples. It was smoked in pipes and “thrown into fires as an offering, cast into the wind
and water to abate storms, scattered about a fish weir to improve the catch and offered (continued) to
the air in thanksgiving for escape from danger”, according to Virgil Vogel’s American Indian
Medicine 1970.
EUROPEAN SETTLERS
The first European settlers in North America, arriving in the early 17th century, tended to dismiss
Native American medical practices as nothing more than primitive savagery. The settlers relied
largely on imported herbal medicines, or on European plants hardy enough to grow in eastern North
America.
As time went by, however, the settlers’ increased contact with indigenous peoples in the frontier
regions fostered a healthy respect for their healing skills. Sometimes settlers adopted not just the
plants but the harvesting and therapeutic methods as well. Joseph Doddridge, in Notes on the
Settlement and Indian Wars 1876, relates that butternut bark was peeled downwards if it was to be
used as a purgative (acting “downwards” by purging the bowels), and upwards for use as an emetic
(acting “upwards” by provoking vomiting).
The types of healing regimes practised by Native Americans eventually gained widespread
popularity. Towards the end of the 18th century, Samuel Thomson 1769-1843 developed a simple
therapeutic regime based on Native American herbal practice. Thomson never acknowledged the
debt, but it is clearly evident – from the use of emetics, purgatives and stimulants, to the central role
of sweating and vapour baths based in part on Native American sweat lodges, to the deep knowledge
of American medicinal plants. Thomson considered that “all disease is caused by cold” and his
system worked well for those with a robust health struck down by infection or injury. The two main
herbs in his system – cayenne, a stimulating herb, and lobelia, an emetic, relaxant and stimulant – act
to raise body temperature and dilate the blood vessels. Taking these plants helps to increase
resistance to infection and speeds the healing of wounds.
ECLECTICISM & ITS INFLUENCE
The fertile marriage between Native American and Western herbal medicine led to the establishment
of more sophisticated herbal systems, such as Eclecticism, founded by Dr Wooster Beech 1794-1868
in the 1830s. Beech studied both herbal and conventional medicine and tried to combine the new
scientific knowledge of physiology and pathology with the best of the herbal tradition. Beech
rejected Thomson’s theories as being over-simplistic, and aimed to use the lowest dosages possible
to achieve good results. His approach was so successful that at Eclecticism’s height in 1909, over
8,000 members were in practice, all with recognized medical qualifications. Another significant
medical movement inspired by Thomson’s regime and influenced by the Eclectics, was
Physiomedicalism.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 32
NORTH AMERICA
Using many herbs, these practitioners sought to harmonize “the organic tissues with the vital force”,
with the aim of restoring equilibrium within the body. Believing the stomach was the source of
disease; Physiomedicalists used herbs that induced vomiting, such as Pokeroot, to cleanse the organ.
Other herbs, such as echinacea, now recognized as an excellent immune—stimulant, and goldenseal
a tonic and anti-inflammatory, were then prescribed to aid recovery.
The second half of the 19th century was an extraordinary time for American natural medicine. In
addition to engendering osteopathy and chiropractic at the turn of the century, it also re-invigorated
herbal medicine in Britain to such a degree that Physiomedicalism became an Anglo-American
herbal tradition. To this day, British herbalists still use a far wider variety of North American
medicinal herbs than do their European counterparts.
NORTH AMERICAN HERBALISM TODAY
In the USA, herbal medicine went into steep decline after 1907 because of the government’s decision
to limit financial support for medical training to conventional medical schools. Since that time,
herbal medicine in both the USA and Canada has existed only on the fringes of conventional health
care. In much of the USA, it is illegal to practise herbal medicine without medical qualifications, but
courses in herbalism are not offered at medical schools.
Herbs are viewed primarily as a source of new pharmacologically active chemicals rather than as
medicines in their own right. The wild yam is a good example. The plant was used in Mexico from
the time of the Aztecs as a treatment for rheumatic complaints and as an analgesic. In 1942,
researchers discovered that it contains a steroid, diosgenin that mimics the effect of progesterone one
of the female sex hormones – in the body. In the 1950s, the Mexican pharmaceutical company
Syntex produced the first contraceptive pill from diosgenin, extracted from wild yam. Few people
realize the role that plants have played in the development of modern pharmaceutical drugs and
fewer still question whether the body might be better served sometimes by the use of whole plants
rather than single chemicals.
With the passing of relatively liberal legislation in 1994, herbal remedies are more readily available
in the USA, but due to regulatory restrictions, they can only be sold as food supplements. This lags
behind developments in the rest of the world, where herbs are recognized as medicines in their own
right. Nevertheless, with the growing number of herbalists in North America, and with the opening
of many schools of Western herbal medicine, herbalism is now stronger and more popular than ever
could have been dreamed of 10 years ago.
SOUTH AMERICA
Herbal medicine is a part of the struggle for survival for the indigenous peoples of South America, as
they seek to protect their culture and natural habitats. As the great rainforests disappear we are losing
thousands of plant species, some of which may have had great medicinal value.
Herbal medicine in South America conjures up images of shamanistic rituals and a collection of
thousands of as yet unclassified plants under the thick canopy of the rainforest. Distinctly different
plants and practices are found in other areas, for example on the Bolivian Andes plateau, on the
humid plains of Paraguay and in cities such as Rio de Janeiro.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 33
WEALTH of NATIVE PLANTS
Ever since the Spanish conquest in the early 16th century, European writers have remarked on the
huge variety of plant medicines used by native peoples. The most important of these was cinchona, a
traditional Andean fever remedy, which the Spaniards first discovered around 1630. Quinine,
produced from this plant, became the most effective treatment for malaria for nearly 300 years and is
still widely used as a tonic, bitter and muscle relaxant. Other important plants originating in South
America include the potato, which was cultivated in over 60 different varieties by the Inca. Its uses
are wide-ranging, but it is particularly effective as a poultice for skin conditions. Ipecacuanha now
commonly found in over-the-counter cough preparations – was taken by Brazilian native peoples to
treat amoebic dysentery. Maté, which grows in western regions of the continent, makes a stimulating
beverage that is prepared and drunk like tea. Maté has become so popular it is now cultivated in
Spain and Portugal as well as in South America.
Since the 1950s, specialist ethnobotanists have lived within native communities, particularly in the
Amazon region, where most tribes have a highly developed herbal lore. Their work has resulted in a
wealth of knowledge about Amazonian species. Pareira, a climbing vine of the rainforest, for
example, yields the poison curare used in hunting, and is taken medicinally to treat water retention,
bruising and insanity. Sadly, however, the herbal medicine of many indigenous groups is now under
threat as the rainforests disappear.
MIND-ALTERING REMEDIES
Notorious in the West as the source of cocaine, coca is an important medicine in South America for
nausea and vomiting, toothache and asthma. It is also completely interwoven into the culture of
indigenous Amazonian and Andean peoples and serves as an example of the unique relationship that
traditional peoples have with the plant world. Many different myths confirm coca’s sacred and
ancient origins in South America, Great ritual and significance is attached to the coca leaves, which,
when mixed with lime and chewed, reduce appetite and increase endurance.
Many hallucinogenic plants are used within South American shamanistic societies, notably
ayahuasca. This powerful “medicine” enables the shaman to communicate with the spirit world and
cure the patient’s ill health.
THE EUROPEAN INFLUENCE
In more westernised areas of South America, herbal medicine is often a blend of both Spanish and
local traditions (as is also the case in Central America). Large herb markets exist in some cities, such
as La Paz and Quito, which provide an astonishing variety of indigenous and European herbs. As an
example; in Ecuadorian markets, anise, a digestive remedy for colic and griping that originally came
from the Mediterranean, is sold alongside unusual native medicines such as arquitecta, a diuretic and
detoxifying herb traditionally used to treat toxicity and infections, including syphilis.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 34
RESEARCH & NEW HOPES
Research into native herbs has led to the use of certain plants in conventional medicine. Brazilian
investigation in to lapacho indicates significant therapeutic potential for its use in the treatment of
fungal infections, inflammation of the cervix, HIV and cancer. While lapacho’s effectiveness in
treating cancer is controversial, it is currently being prescribed by both local doctors and is being
used in hospitals.
Research into herbal medicine is expanding, with a hospital-based centre in Santa Fe de Bogota in
Colombia exploring indigenous herbs. Such studies are important for the world as a whole. The
locally based researchers, unlike most multinational drug companies, are willing to develop
medicines based on simple extracts, which may ultimately prove more effective than the isolated
constituents often used in conventional drugs.
Modern herbal medicine represents a complex interweaving of different cultures – a combination of
European folk tradition and Eastern influences overlaid by the introduction of New World plants and
healing practices and by more recent scientific discoveries. Over-the-counter herbal products draw
on this rich mixture with preparations clearly influenced by successive schools of thought. Some –
many of them formulated in the 1930s – concentrate on herbs traditionally used by Native
Americans, others focus on the more recently discovered healing properties of particular plants, such
as circulatory remedies using ginkgo, or tonics containing cat’s claw.
Because of current licensing and labelling regulations it is not always obvious why a particular
product contains the herbs that it does and thus an understanding of the theories which influenced its
developers can help explain the products likely therapeutic properties and benefits.
While conventional allopathic medicine concentrates on removing symptoms, the usual herbal
approach is to “restore balance” and strengthen the system so that the vital energy of the body can
combat disease and restore health. Certainly, herbal remedies can be designed simply to relieve
symptoms, but most also focus on long-term cures so that unlike some orthodox drugs – when the
sufferer stops taking the tablets the symptoms do not return. An herb like St John’s Wort, for
example, is used as an anti-depressant, but it also acts as a tonic for the nervous system so rather than
just providing a short-term uplift in mood it addresses longer-term needs. Similarly, while echinacea
is an effective anti-bacterial, anti-viral and anti-fungal, it also helps to stimulate the immune system
to counter infections more effectively in the future.
European traditions
Herbal medicine has, of course, been practised in Europe for thousands of years and such writers as
Pliny and Dioscorides described the actions of many of the plants commonly used today in the first
century AD.

Greek and Roman medicine was based on the theory of “humours” which taught that the four vital
fluids in the body had to be kept in balance and all illness could thus be defined in terms of humoral
imbalance. This model was related to the belief that the world was composed of four elements: earth,
air, fire and water which each had its corresponding humour. These humours – blood, phlegm, black
bile and yellow bile – not only dictated health but also temperament. A person in whom black bile
dominated was thus termed “melancholic” and tended to depression while someone with a surfeit of
blood was “sanguine” and likely to be cheerful and amusing but probably prone to over indulgence.
Although early Greeks like Hippocrates had described the basic humoral theory in the fifth century
AD, it was more precisely codified by Galen 131-199 AD so is often termed “Galenical medicine”.
The humours were regulated by various drastic treatments: bleeding the patient to remove a surfeit of
blood or giving strong purgatives to clear excess black bile. The humours were also defined in terms
of cold or heat, dry or dampness, and herbs were similarly characterized. Phlegm, for example, was
associated with cold and dampness so surfeit would be countered by a hot and dry herb to restore
balance. Thyme and hyssop both fall into this category and were prescribed for the sort of
phlegmatic excess one encounters in the common cold.
Old herbals often describe the temperature of plants in great derail. John Gerard, writing in 1597, for
example, tells us that motherwort is “hot and dry in the second degree” while chickweed is “cold and
moist and of a waterish substance”.
The appearance of herbs was also important under the Doctrine of Signatures. This argued that plants
contained clues to their medicinal properties in their appearance: yellow flowered herbs, for
example, were believed to be helpful for jaundice while Pilewort with its nodular roots was clearly
ideal for treating haemorrhoids. Some of these interpretations were in fact quite valid, Pilewort is
good for haemorrhoids and yellow-flowered dandelion makes a good liver herb, although others,
now largely forgotten, were less accurate.
While most of European herbalism continued to draw on this common Greek and Roman tradition
until well into the eighteenth century, there were important regional differences. In Germany, for
instance, the visionary nun Hildegard of Bingen had been inspired to produce a herbal in the eleventh
century which contained some quite original uses of herbs. She recommended, for example, vervain
for skin infections, mint juice for arthritis, and galangal for heart disorders. Some of these ideas
derived from local folk traditions; others, Hildegard believed, were instructions from God that came
in her visions.
Although Hildegard’s writings were largely forgotten until comparatively recently, the sort of cures
she advocated remained an undefying influence on herbal use in some parts of Europe. Today, her
work has been revived and the practice of “Hildegard medicine” is thriving in many parts of
Germany and Austria. Both the Jura pharmaceuticals company in Konstanz and St Hildegard Posch
in Austria make and market over-the-counter herbal remedies based on her theories. Some of these
products are now available in the UK.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 36
Since the nineteenth century, use of herbs in mainstream medicine in mainland Europe has
remained more widespread than in the UK; indeed materia medica” – the medicinal herbal repertoire
– has continued to be taught in many Central European medical schools until the present day. Herbal
products from French, Swiss and German suppliers thus tend to draw more heavily on European
traditions than those produced in the UK. Herbs like sanicle, paracress and hemp nettle, which have
long-since vanished from the British herbalist’s medicine chest, are still used elsewhere in Europe.
Some of these remedies and supplements are also marketed in the UK and, as cross-border trade in
medicinal products within the EU increases, more will surely follow. Many of these herbs are not
listed in commonly available English language herbals so it can be difficult for the average lay
person or indeed their GP to discover what the actions of a particular remedy are likely to be.
Homoeopathic tradition is also important in mainland Europe. This theory argues that very dilute
herbal extracts will cause particular symptoms, while the same brew can then be used to cancel out
such symptoms when they occur in illness.
Homoeopathy was developed by Samuel Hahnemann in Leipzig between 1811 and 1820 and many
of the plants he used were common medicinal herbs. Their use in homoeopathy is, however,
generally quite different from mainstream herbalism. Bryony, for example, is a potent herb used for
treating bronchial congestion and rheumatic complaints; it is also strongly purgative. In
homoeopathy a tincture of this same herb is diluted to such an extent that it is almost impossible to
detect its presence. The remedy is then used for treating certain types of common colds.
Herbs which are extremely toxic and restricted by law to professional practitioners in normal dosages
are widely used in homoeopathy; which means that toxic substances like autumn crocus, deadly
nightshade or poison ivy may appear in remedies quite safely. Some European suppliers, such as the
Swiss company Bioforce, combine both standard herbal extracts and homoeopathic dilutions in their
products so, although the contents may seem poisonous, they are actually quite safe. The more dilute
a homoeopathic remedy is, the more potent it is believed to be. The number of times the mother
tincture has been diluted is indicated after the name of the remedy: “Chamomilla 3x’ means that
chamomile has been diluted only three times which is a fairly concentrated remedy and therefore less
potent; “Arnica 30x” indicates that there have been 30 dilutions and the medicine is considerably
stronger.
Not all homoeopathic medicines are herbal: various minerals such as sulphur and graphite are used
along with animal products like snake venom [Lachesis] and the poison from honey bees [Apis
mellifica].
Also important in European tradition is the anthroposophical medicine developed by Rudolf Steiner
in the 1920s. Like Hildegard, Steiner was a visionary and his theories drew on a combination of
Galenical theories and homoeopathy combined with his holistic view of health and insights about the
healing properties of particular plants. The main aim of anthroposophical medicine is to stimulate the
body’s natural healing powers and Steiner believed that spiritual well being and the role of the soul
were of equal significance in good health.
Anthroposophical medicines are produced worldwide by Weleda, a company that still follows
Steiner’s precepts. Most of the herbs used are familiar in either herbal or homoeopathic tradition
although some of the combinations are more strongly derived from Steiner’s unique inspirations.

Physiomedicalists and American influence
While homoeopathy and anthroposophy prospered in mainland Europe, herbal medicine in
nineteenth century Britain reached a nadir. The Industrial Revolution drew vast numbers of people
into towns, away from their rural roots; herbal folk medicines, which had been maintained in
families for generations, were lost and the emphasis was increasingly put tto use patent remedies.
The revival started in the 1840s and 1850s when the unlikely named Albert Coffin and Wooster
Beech arrived from the United States with their messages of “Physiomedicalism” and “Eclecticism”.
The Physiomedical movement had been founded in the 1790s by Samuel Thomson, a New
Hampshire herbal practitioner who combined pioneer medical traditions with Native American
theories. He believed that all disease was caused by cold, hardly surprising in the bitter New England
winters, and he used sweating remedies, popular with many East Coast tribes, to warm his patients.
In general, Thomson favoured a combination of enema’s and purgatives to clear the system of cold
and damp phlegm.
As in Galenical medicine, health to the physiomedicalists meant maintaining internal balance to
ensure a healthy ‘vital force”. Herbs were classified as stimulating or sedating, relaxing or astringing
and combinations were used to restore balance to both tissues and mental states.
Irritable bowel syndrome, for example, might be treated in a Physiomedical approach with
chamomile to sedate the nervous system and relax the digestive tissues, followed by an astringent
like agrimony to counter any over-relaxation so caused, and a stimulant such as ginger to encourage
the vital force.
The Eclectic school combined herbal remedies and Native American healing traditions with more
orthodox medical techniques and at one time the movement boasted 20,000 qualified practitioners in
the United States. Wooster Beech’s message proved extremely popular in the industrial towns of
Northern England and Eclectic systems thrived there until well into the 1930s.
This North American influence can still be seen in many of the herbal remedies produced by
traditional UK suppliers such as Porter’s and Frank Roberts. American herbs, like Bayberry,
Helonias, Indian tobacco and pleurisy root, are included in their remedies, yet these plants are
virtually unknown in mainland Europe. They are often poorly researched, partly because a great deal
of herbal study is undertaken in Germany where such traditional New World remedies are little
known. These herbs do, however, make extremely potent and effective medicines.
The physiomedicalist emphasis on mixtures to counter cold can also be seen in many traditional
British products – notably in brews like Potter’s Composition Essence.
Modern plant hunters
Plant hunters have been gathering exotic specimens and adding them to the herbal repertoire since
the Portuguese set out to navigate the world in the 1450s. The Spanish brought back potatoes and
cinchona from South America, missionary Jesuits learned of ginseng in Korea, and an observant
Boer farmer first noted the use of devil’s claw in the 1930s.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 38
The search goes on, and today, pharmaceutical companies around the world are investigating plants
that are used in many ethnic traditions with a view to extracting, and subsequently patenting, active
constituents. While some of these plants form the basis of new orthodox drugs [such as taxol
extracted from the Pacific yew tree which is being used successfully to treat ovarian cancer], others
prove too complex to ever yield a patentable single ingredient and thus join the mainstream herbal
repertoire.
Researchers today focus not only on exotic plants from the Amazon rain forests or Kalahari Desert,
but also on more mundane European species, which thus take on a new lease of life. Burterbur, for
example, was regarded as a not particularly important cough cure until the 1950s when Italian
researchers discovered that it also had considerable antispasmodic and pain relieving properties and
the herb suddenly joined the ranks of digestive remedies. St John’s Wort has similarly been more
recently identified as an immune stimulant; garlic is now well established as an anti-cholesterol and
prophylactic for arteriosclerosis, and feverfew has proven to be a far better migraine remedy than
traditional herbals imply.
Over the past few year’s newcomers such as echinacea, ginkgo and devil’s claw have started to
appear in over-the-counter products. Like commercial companies everywhere, makers of herbal
products aim regularly to launch something new and novel to tempt the buying public; sometimes the
marketing hype can suggest that these herbs are considerably more potent than they in fact are and
occasionally rather inappropriate applications are implied. Ginkgo, for instance, certainly boosts
cerebral circulation and can speed recovery after brain surgery, but suggesting that it maybe of
cosmetic benefit for varicose veins is a little odd.
Suppliers’ enthusiasm for a newly discovered plant can also outstrip the popular herbal literature.
Peruvian cat’s claw, for example, was only identified in the 1970s and reports of its actions in the
scientific press largely date from 1989-92. It is now available in capsule form as an over-the-counter
tonic – yet the plant is not yet listed in mainstream herbals so potential customers will find
information about the product hard to come by. The same applies to other such Amazonian exotics as
paratudo and catuaba.
The herbal repertoire is constantly expanding and while it once took decades for a plant to become
established and readily available as an over-the-counter product, we are now seeing newcomers
appearing on the shelves in health food stores within a year or two of the first significant literature
reports. It may give the producers plenty of new lines to promote, but it can be confusing – both for
the public who are expected to buy them and for health care professionals who need to advise on
their suitability and contra-indications.
Early and Ancient Herbalists
SINCE repeated references to these is given in this lesson a brief background concerning the
individual herbalists of early and ancient times is in order.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 39
Concerning the extracts from old Herbals a special word must be said. They have been added
because of their historical interest, and the languages of the Elizabethan herbalists is so beautiful,
amounting to poetic prose, that extracts from these books form delightful reading, even if the
subject-matter deals with mundane complaints. Herbalists like Parkinson, Gerard and Culpeper
frequently quote the ancient Greek and Roman herbalists, translating the Greek and Latin into quaint
Elizabethan English. Notes concerning the individual herbalists who are from time to time quoted
should be of interest and I will give them now, dealing first with well-known English writers.
John Gerard, of London, was born at Nantwich in Cheshire in 1545, but came to London, settling
eventually in Holborn. The introduction to his book is “From my house in Holborn within the
suburbs of London.” Gerard became a “Master of Chirugerie”. His best known work ‘The Herball or
General Historie of Plants’, was first published in 1597. A second edition of this work was published
in 1636, twenty-five years after his death in 1611, and it is described on the title-page as very much
enlarged and amended by Thomas Johnson, a Citizen and.Apothecarye of London. This edition runs
into 1,630 large pages. The original author’s name is spelt variously as Gerard, Gerarde and Gerrard.
John Parkinson, a contemporary of Gerard, was born in 1567 and died in 1629. He became an
Apothecary of London and King’s Herbalist, he was also a director of the Royal Gardens at Hampton
Court. He wrote two well-known works, the first ‘Paradisus Terrestris’, published in 1629 and the
second ‘Theatrum Botanicum’, or an Herbal of large extent… which was printed in 1640.
Nicholas Culpeper was the man of whom Dr. Johnson wrote “Culpeper, the man that first ranged the
woods and climbed the mountains in search of medicinal herbs, has undoubtedly merited the
gratitude of posterity.” He was the son of a clergyman and grandson of Sir Thomas Culpeper, Bart.
After studying at Cambridge he became apprenticed to an Apothecary. In his leisure hours he studied
Physics and Astrology, and eventually set up his practice as an Astrological Doctor “in Spitalfields,
next to the Red Lion”. The district is interesting, as up to a few years ago one of the few firms still
dealing in herbal products had its warehouses near this spot. Culpeper’s herb gardens are
commemorated by the names of streets, such as Wormwood Street and Camomile Street, in the City.
He died in 1654 and his best-known work is entitled ‘The Complete Herbal and English Physician’.
Joseph Miller was the author of ‘Botanicum Officinale’, or a Compendious Herbal, published in
1722.
John Hill, M.D., wrote ‘A general Natural History’, or new accurate descriptions of the Animals,
Vegetables and Minerals of the different parts of the world, printed in 1751, and ‘British Herbal’, an
History of Plants and Trees Native to Britain, cultivated for use or praised for Beauty, in 1756.
William Salmon, M.D., wrote ‘The English Herbal’ or History of Plants in 1710.
Benjamin H. Barton, F.L.S., and Thomas Castle, M.D., F.L.S., collaborated in the production of two
volumes entitled ‘The Medicinal Plants of Great Britain’, published in 1845.
Of the more ancient herbalists, there are many, starting with Solomon, and continuing through the
ages, of these, I can mention only a few.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 40
Theophrastos Eresios, of Eresos in the island of Liesbos,lived from about 370 B.C. to 285 BC. He
succeeded Aristotle in the government of the School of Athens about 322 BC. He is the earliest
known European botanical author and wrote his work about 314 B.C. He is said to have shown a
great amount of excellent observation and it is likely that some of his works originated from
Aristotle. These were printed as early as 1483 and have been translated into several languages.
Pliny-Caius Plinius Secundus-lived from 23 to. 79 AD and is the well-known author of ‘Naturalis
Historia libri XXXVII’, subsequently translated into French. He met with an untimely end by reason
of an eruption of Vesuvius. As Thomas Johnson put it “He was suffocated by the sulphurious
vapours that came from Mount Vesuvius falling at that time on fire: he through overmuch curiositie
to see and finde out the cause thereof approaching too nigh.”
Dioscorides, whose main writings were accomplished about A.D. 77 or AD. 78, lived in Anazarba in
Cilicia, Asia Minor. His work on Materia Medica is considered to be the most valuable source of
information on the botany of the ancient herbalists.
Galen (Galenos) lived from 131 to AD. 200 and whilst he was Imperial Physician in Rome wrote
many distinguished medical books which were held in high reputation right down to the Middle
Ages. The term “galenical”, used to describe many medicinal preparations, is derived from his name.
Hilarius, Matthiolus, the Italian Physician, Clausius, best known for his translations of Spanish
herbal writings, Sammonicus and the Swiss Physician Paracelsus, are among many others that
contributed their quota to the knowledge of herbs which has been passed down to us through the
ages.
Perhaps Paraselsus should be mentioned apart from the others as he introduced many unsavoury
things into medicine, some of which had been used by the Egyptians, such as various forms of
excreta. His writings went so far as to influence the London Pharmacopoeia of 1617 to introduce
some of these. He also did much to make popular the Doctrine of Signatures in which many believed
at that time. This was a belief that the colour or shape of a plant, or part of a plant, indicated its use in
the cure of ailments where the colour or shape had some relationship to the complaint. It was thought
that this stamp or signature was laid on the plant by a guardian angel. Thus, because the leaves of the
Lungwort were spotted, it was thought to be useful for pulmonary complaints. Plants with yellow
flowers or roots with yellow sap would be suitable for jaundice. Red-coloured roots were used for
bleeding. The root of the Bryony, because it is shaped like a swollen foot, was thought to be good for
dropsy. Poplar leaves, which because they shake in the breeze in a peculiar way are known as
Quaking Aspen leaves, were, of course, the right thing of shaking palsy. One could instance many
other examples of the same kind of thing. It was a doctrine subscribed to by a great number of
eminent herbalists, and led to the belief that heavenly bodies, the planets, the stars, the sun and the
moon, had an influence on plants. This was further developed by Culpeper, who made a great study
of Astrology, and in ‘The Complete Herbal’ he sets out his method of astrological diagnosis and
treatment as follows:
1. Consider what planet causeth the disease; that thou mayest find it in my aforesaid Judgment
of Diseases.
2. Consider what part of the body is affected by the disease and whether it lies in the flesh or
blood or bones or ventricles.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 41
3. Consider by what planet the afflicted part of the body is governed; that my Judgment of
Diseases will inform you also.
4. You may oppose diseases by herbs of the planet opposite to the planet that causes them; as
diseases of the Luminaries by the herbs Saturn and the contrary; diseases of Mars by the
herbs of Venus and the contrary.
5. There is a way to cure diseases sometimes by Sympathy and so every planet cures its own
diseases; as the Sun and the Moon by their herbs cure the eyes, Saturn the spleen, Juniper the
liver, Mars the gall and diseases pf the choler, and by Venus, diseases in the Instruments of
Generation.
Culpeper in in his ‘Judgment of Diseases’ sets out this theory in much greater detail.
The vegetable life of the world has become surrounded by fables, legends and superstitions. The
reason for this is probably contained in a paragraph of Charles M. Skinner’s ‘Myths and Legends of
Flowers, Trees, Fruits and Plants’, where he writes: To primitive people who thus symbolized natural
phenomena, vegetable life was, in a manner, glorified, because it sustained all other life. The tree
supplies lumber, fuel, house, thatch, cordage, weapons, boats, shields and tools, as well as fruit and
medicine. Many of these myths and legends make interesting reading, but there is not much
opportunity of dealing with them exhaustively here. The subject forms an absorbing study on its
own.
The period of modern pharmacognosy is young, dating from the early nineteenth century, and some
of the best work in modern times has been carried out by the late Dr. Henry Greenish. His Text Book
of Pharmacognosy, first published in 1899, has run into many editions since.
The study of herbs, roots, barks, fruits has now become a fine art.
Theories like the Doctrine of Signatures [see next lesson] and the Doctrine of Planets, although
remaining interesting historically, have been laid aside and have been replaced by scientific
investigation. Much good and useful work has been, and still is being done by chemists to discover
and extract the active principles of those plants that appear to have an effect on the human system.
There is of course a lot more research that still has to be done. Although it is known that a lot of
plants used by the herbalist of today have a beneficial healing effect on their patients it remains a fact
that in a lot of cases the reason for the benefit is not known. Because of this, some people are
inclined to scorn the use of herbs. Many of us believe however, that as the chemistry of plants
advances it will be discovered that there is a very good reason for their use and that some may prove
superior to many of the synthetic chemical drugs used today.
HERBS FROM THE BEGINNING
Historically, the oldest uses of herbs have been in corrective or preventative medicine uses. Perhaps
this is because much of the lore of herbs is derived from the herbals – the plant medicine books. It is
to these ancient volumes that we tend to turn to when determining whether or not a plant may
properly be called an herb. There are, of course, other herbal uses explained, but even the culinary
and aromatic qualities seem tied to the curative, salutary, or hygienic properties of the plants.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 42
Sweet-smelling pomander balls and herbal bags were not only used for the ole-factory aesthetics
involved but for the supposedly hygienic effect of the scents they provided in the midst of the stench
of rotting garbage, putrefying sewerage, disease, and death. A cook used herbs on meat not so much
because the herbal flavor was appetizing but rather because the taste of meat going bad was not. At
least psychologically, such culinary and aromatic uses had a salutary effect.
Probably because so much herbal lore seems to derive from three Elizabethan herbalists – Nicholas
Culpeper, John Gerard, and John Parkinson. While there are some herbs that are native to England,
just as some are uniquely American, the blue-bloods are almost all of Mediterranean origin and
ancestry. And while a rich body of lore is found in sixteenth – and seventeenth century English
herbals, it has to be admitted that at least a core of that lore is derivative of material first recorded by
Greek herbalists and passed through the rise and fall of Rome into the Dark Ages, emerging in the
works of monks.
The Ebers Papyrus, which said that Egypt, 2000 years before Christ, had about 2000 herb doctors.
The Bible, in both Old and New Testaments, makes repeated references to herbs. These references
serve to substantiate the import of the ancient papyrus: that herbs were well known in ancient Egypt.
“And ye shall take a bunch of hyssop, and dip it in the blood that is in the basin, and strike the lintel
and the two side posts with the blood that is in the basin; and none of you shall go out of the door of
his house until the morning.” The instructions from Exodus 12:22 may stick in your mind, though the
identity of the herbal brush might not (it should be noted that scholars believe the hyssop of this
reference is Origanum aegyptiacurn rather than Hysso pus officinalis, the latter being today’s
hyssop). Similarly, many will recall the story of Manna, but not its description: “And the house of
Israel called the name thereof Manna; and it was like coriander seed, white; and the taste of it was
like wafers made with honey” Exodus 16:31. Other references to herbs appear in the Book of
Numbers and the Proverbs.
But other than these Old Testament references and the Ebers Papyrus, much of what we know about
the herb knowledge of this period is somewhat speculative. We do know that in later years the
Greeks, as you might expect, studied the herbs and committed their observations and speculations to
writing. For them, too, the herbs were well known. Aristotle had a garden of more than three hundred
plants that were reputed to have medicinal qualities according to Theophrastus. The latter was a pupil
of the great teacher and thinker and had the opportunity to study and write about Aristotle’s herbs.
Four centuries later, about the time of Christ’s birth, Dioscorides, a Greek physician, wrote a justly
remembered herbal.
Tbeophrastus and Dioscorides produced the most remarkable herbals, but information about herbs
and references to them appeared in the works of Pliny the Elder, Galen, Vergil, and Homer. New
Testament references indicate that herbs continued to be commonplace. The Greek record was
passed along to the Romans, who made extensive medicinal and culinary use of herbs. Indeed, the
spread of the Roman Empire might be credited with the spread of herbs, for the Roman armies
carried them everywhere, planting them inadvertently in some spots, by design in others.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 43
Where the Romans left off, the Christians picked up. In the Dark Ages, the monasteries of
Benedictine and Cistercian orders were the centres of herbal activity. Individuals all over Europe had
herb gardens, much as they had vegetable gardens, but the monks of these orders collected and
cultivated as many varieties as they could find, serving as the most formal vehicle for the
perpetuation of the use of herbs for healing. More important perhaps, the monks developed and
maintained a record of their lore. Most of their herbals drew heavily on the works of the Greeks, and
the illustrations they provided lacked any reasonable semblance to the plant depicted. Nevertheless,
the contribution of these pious men was invaluable.
As civilization struggled out of the Middle Ages, the herb garden gained a new respectability and
status. It still was a part of the monastery setting, and of the kitchen garden at individual homes and
manors across the land. But the garden was being formalized in the capitals of the Renaissance, and
the herbs were a focal point of these elaborate ornaments. As the Renaissance continued, important
new contributions were made to the existing body of herbal knowledge, which had simply been
regenerating for centuries. In 1475, the first wood cuts known to be used as botanical illustrations
appeared. They appeared in a work called Des Buch der Natur, published by Konrad von Meganberg.
Slightly over one hundred years later, in 1597, the first major new herbal appeared, and it remains
one of the best-known of the many the era engendered. The book is commonly known simply as
Gerard’s Herball and was the work of an Englishman John Gerard. Born in 1545, Gerard was a
surgeon, but he made his mark in English society serving finally as the apothecary but formerly the
superintendent of the gardens owned by James I.
The next notable herbal of the period was written by another apothecary to James I. This writer’s
name was John Parkinson, and his herbal Theatrurn Botanicum was produced in 1640. Only a few
years later, sometime between 1649 and 1653, came what is perhaps the most readable of the herbals
of this period, the one written by Nicholas Culpeper. Culpeper’s effort was based more in
superstition and folklore than the works of Gerard and Parkinson. While this did contribute to the
readability of the book, it also contributed to an overstatement of the value of many of the plants.
One of the more curious superstitions recorded by Culpeper [and others before him] was the
Doctrine of Signatures. “And by the icon or image of every herb, man first found out their virtues,”
he wrote. “Modern writers laugh at them for it, but I wonder in my heart how the virtues of herbs
first came to be known, if not by the signatures. The moderns have them from the writings of the
ancients – the ancients had no writings to have them from.”
According to this belief, the medicinal use of a plant could be determined from some element of its
appearance. The spotted, lung-shaped leaves of the Lungwort indicated to the ancients that it was
good for curing diseased, or spotted, lungs. The hollow stalk of the garlic showed it was a remedy for
windpipe ailments. Some weeds-like dandelion, plantain, yarrow, and nettles-revealed the broadness
of their healing virtues through their abundance.
Equally pervasive in Culpeper’s herbal is his belief in astrology. Invariably his entries on herbs
include some commentary on the influence of the moon, the planets, and the constellations on the
plant. While this is regarded as the rankest form of superstition in some contemporary herb books, it
should be remembered that some very successful gardeners and farmers still plant and harvest
according to the phases of the moon. And while astrology may be in scientific disrepute, it is hardly
in popular disrepute.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 44
It is perhaps worth noting that most of Culpeper’s work is still, as of this writing, in print, being
available under the title Culpeper’s Complete Herbal. Extensive excerpts from Gerard’s herbal have
been published by Dover Publications under the title Leaves from Gerard’s Herba ii. Selections from
many old herbals are included in a number of books written about herbs.
About the time these Englishmen were collecting their herbal lore into book form, other Englishmen
were moving to the New World. They were taking, along with everything else, their healing and
savoury-plants. As had been true with all these ages, the first settlers in the new land counted on the
herbs primarily for their salutary qualities. Their healing properties combated illness, their scents
masked the poor sanitation, their flavours masked bland or spoiling food.
But the New World was just that, a new land with a population and a plant world of its own. The
new arrivals discovered that the native peoples had a vast herbal knowledge of their own. They
discovered that some of their plants didn’t thrive in the new land, while others did quite well. The
upshot was the development of a new body of herbal lore, a body recorded largely by the naturalized
Americans.
The American Indians formed their herbal lore much the same way other peoples formed theirs. The
doctrine of signatures that Culpeper described found practitioners in America. Similarly, the Indians,
like their contemporaries around the globe, were superstitious, and they based some plant uses in
superstition. And of course in every age and civilization their are experimenters. However the uses
were determined, the Indians did have some use for almost every plant native to their land.
What happened as the immigrants started arriving was that the Indians passed along what they knew
of their plants and learned about plants that the new arrivals had brought with them. The new arrivals
probably taught them a few things about the Native American plants, and the Indians discovered
some things about the naturalized plants that the newcomers were not aware of. Herbal knowledge
was rapidly expanding.
Undoubtedly the first written record of the native American herb lore was made by Juan Badianus, a
native Mexican Indian doctor. Badianus had been educated by priests and in 1552 wrote a
manuscript, in Latin, recording native medical practices.
Two Englishmen, William Wood and John Josselyn began the exchange of herbal knowledge
between the new and old worlds in the seventeenth century. In 1634, Wood published in London a
book titled New England Prospect, basically reporting on the new world as he observed it. The book
included a chapter, “Of the Hearbes, fruits, woods, waters Josselyn’s book was published in 1672,
again in London, and its almost interminable title admirably captured the gist of the text: ‘New
England’s Rarities Discovered: In Birds, Beasts, Fishes, Serpents, and Plants of that Country’.
Together with The Physical and Chyrurgical Remedies wherewith the Natives constantly use to Cure
their Distempers, Wounds and Sores. Also A perfect Description of an Indian Squa in all her
Bravery; with a Poem not improperly conferred upon her. Lastly A Chronological Table of the most
remarkable Passages in that Country amongst the English.
Other writings and researches on the uses of plants followed, of course. In the late seventeenth
century, the first arboretum was established in America by a Bavarian named Johann Kelpius, who
was residing in Germantown, outside of Philadelphia. Kelpius was interested in testing the medicinal
plants he had heard about from the Indians.

Philadelphia was also the home of the man who brought official medical recognition to the Indian
herbal cures. Dr. Benjamin Rush, a respected physician, investigated the cures and published his
findings. His work spawned a flurry of compilation activity and soon a variety of guides to Indian
medicines became available. Perhaps the most notable and valuable of them was written by Dr.
Benjamin Smith Barton, a fully accredited physician. Barton, another Philadelphian, lived from 1766
to 1815. His written work was called the Maleria Medica of the United States.
One of the weightier of the guides was an 800-page, $20 manual published in 1822, and the work of
a self-taught physician named Samuel Thomson. The New Hampshire native soon discovered that
his most efficacious prescriptions were being widely duplicated and often misrepresented. In 1813,
Thomson selected certain of his plant compounds; those most useful in treating easily diagnosed
ailments, and had them patented. It began the era of the patent medicine, a notable though not
necessarily illustrious period. For his trouble, Thomson found himself in almost perpetual litigation
for the remaining thirty years of his life. Then as now the medical establishment didn’t appreciate the
work of non-establishmentarians.
Although it would probably have to be concluded that Thomson failed in his attempt to protect the
unwary from the unscrupulous with his medicine patents, the patenting of medicines to widen their
availability did provide a major impetus to growers of medicinal herbs. Diligent though they might
be, the backwoods plant foragers simply could not meet the demand. Growers stepped into the gap.
Among the most interesting of the growers were the religious communities established in various
locations throughout the eastern United States by the Church of the United Society of Believers,
more commonly known as the Shakers. The first Shaker medicinal herb garden was cultivated in
New Lebanon, New York in 1820. Thirty-seven years later the Shakers were still cultivating
medicinal plants, the New Lebanon community having marketed some seventy-five tons of plants its
members raised and dried. The Shaker product list included well over 300 kinds of seeds, flowers,
leaves, and barks, as well as a nearly equal number of medicinal preparations. The Shakers continued
their herb-growing business into the second half of the twentieth century, giving it up only when
sharply dwindling community membership forced them to.
The tendency exists to attribute such things as the decline of the Shaker herbalists to a decline in
interest in plant medicines, but this is not strictly true. Scientific and technological developments in
the twentieth century have led to increasing use of synthetics in pharmaceuticals, but there remain a
large proportion of medicinal substances that can reasonably be derived only from plants. Nearly half
of all prescriptions contain some drug derived from a plant. In 1967 alone, medicinal plants
accounted for £200 million worth of pharmaceutical business. Thus there has been a steady demand
for medicinal plants, a demand emphasized during and after the two World Wars, chiefly because of
the embargoes and increased needs endemic to war. The wars seemed also to spawn revivals of
popular interest in herbs.
One result of the first revival was a two-volume work called A Modern Herbal. The author, Mrs.
Maude Grieve, an English-woman, was a leader in the revival and wrote a number of books. Her
herbal is probably the most thorough and up-to-date book of its type. Undoubtedly, quite a number of
the other herbals and herb books of twentieth century origin can be traced to one or another of the
revivals.

This view of herbal history, of course, reflects a Caucasian view of civilization. But a fabulous lode
of herbal lore, and the people who are perhaps today’s most accomplished herbalists, are found in the
Oriental half of the world. If one accepts the Oriental, predominently Chinese, herbal lore at face
value, one accepts the Chinese lore as the oldest in the world. The dates traditionally given for the
writing of the oldest Chinese herbal would, if true, make it nearly a millennium older than the Ebers
Papyrus.
This oldest of the Chinese pharmacopoeias, Pen-ts’ao (or Herbal), is reputed to be the work of the
Emperor Shen-nung, a great cultural hero who is said to have lived from 3737 to 2697 B.C. Shen-
nung is said to have compounded and self-tested hundreds of herbal preparations, aided by a
transparent abdomen which enabled him to observe the workings of his internal organs. The freakish
condition was undoubted a gift of legend, rather than of nature. Recorded in the Pen-ts’ao are 365
medical preparations, all but 51 of which are herbal.
The emperor who succeeded Shen-nung was also interested in medicine and prepared his own
medical text. The book, Huang-ti Nei-ching or The Yellow Emperor’s Classic of Internal Medicine,
is less of an herbal and more of a comprehensive review of the state of medical arts in China. It is
presented as a dialogue between the Yellow Emperor, Huang-ti, and his chief minister, Ch’i Po.
Huang-ti is said to have ruled from 2697 to 2595 B.C. The authenticity of both these works is in
question, however. The ancient Chinese had a propensity for attributing their writing to older sources
in hopes of bolstering their value, and such is probably the case here. Studies have placed the two in
the first millennium before Christ, making them not as old as the Ebers Papyrus. Despite the
discrepancies of the dates, the Pen-ts’ao and the Huang-ti Nei-ching are still valuable and legitimate
old herbals.
Some time prior to the birth of Christ, the Chinese and their neighbours in India exchanged medical
information, enhancing the knowledge of both peoples. Curiously, though the Eastern and Western
civilizations centuries later opened trade, there was apparently never an exchange of medical
information, to the extent there was here and in the contacts between the Europeans and the
American peoples. Nevertheless, the herbal knowledge developed in China and other Oriental
countries is almost completely compatible with that developed by the Westerners.
The first major Chinese medical work to be translated into Western languages was the Materia
Medica of Li-Shih-Chen, a masterpiece written by Li-Shih-Chen during the sixteenth century. A
great compendium of remedies, it listed 12,000 prescriptions and formulas and analysed 1,074 plant
substances, 443 animal substances, and 354 mineral substances. The book is still studied by
traditional Chinese physicians, who are very important people in Chinese medicine today.
For unlike the Western nations, where the typical medical practitioner disdains intuitive folk
medicine practices, the Chinese today are basing their research and practice on the traditional
theories and techniques. The Chinese typically steer their own course, but during the regime of
Chiang Kai-shek 1912-1949, the western influence was officially favoured and traditional medicine
fell into disrepute. With the ouster of Chiang in 1949 came a resurgence of Chinese nationalism. The
guiding principle today has been articulated by Chairman Mao: “Chinese medicine and
pharmacology are a great treasure house. Efforts should be made to explore them and raise them to
the highest level.”
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 47
Joining in the rise to the highest level are the herbal remedies. Herbs are widely cultivated, chiefly
for their medicinal qualities. Even military installations have prominent herb gardens, each plant
carefully labelled, from which plant medicines are derived and in which the soldiers are taught to
identify medicinal plants, to enable them to forage for healing plants in field situations. Paramedical
personnel work closely with the people, using herbal remedies to a great extent. Moreover, as one
Western observer put it, “Everyone in China is a little bit of an herbalist. The housewives, the
farmers, and even the school children grow herbs and learn to recognize them. Furthermore, herbs
are easily available at stores, are extremely cheap, and are reasonably safe to use.” Coupled with the
resurgence on the popular level is the emphasis on clinical and laboratory research on the healing
plants. Of course, there is some interest in this work throughout the world, but the Chinese seem to
be the leaders.
In the United States today there seems, too, to be resurgence of popular, and to some degree
scientific, interest in herbs. The spread of information on the current Chinese culture may be a
contributing factor.
More and more people are turning to gardening, to homesteading or part-time farming, to home
crafts, to quieter and simpler pleasures. And certainly herbs are a quiet, simple pleasure, yet a
pleasure that shouldn’t be denied as too modest. The pleasure of herbs is a never-ending one, rooted
in the fact that herbs are a way of life.
More than half the world’s population relies on herbs for health. In the Far East, Traditional Chinese
Medicine (TMC) has been successfully treating patients with complex herbal remedies that have
remained unchanged for thousands of years. Aristotle was a firm believer in plant power and he
decided that the body consists of four ‘humours’, the liquids of blood, phlegm, yellow bile and black
bile. He wrote that these need to be kept in balance in order to maintain good health. In ancient
times, herbs were described according to how they affected these ‘humours’. For example, lemon
balm was described as a herb which ‘driveth away all troublesome care and thought out of the mind,
arising from melancholy and black choler’. Although the language is archaic, many terms remain in
modern-day medicine. For example, patients are still described variously as being sanguine,
phlegmatic, choleric or melancholic.
It is unfortunate that we have largely lost the use of so many of the old remedies passed down from
our own famous seventeenth-century herbalists Gerard and Culpeper. Much of their work holds true
today although their original writing is very old fashioned. In the 1650s, herbalist Culpeper wrote
‘Truly my own body being very sickley, brought me easily into a capacity to know that health was
the greatest of all earthly blessings, and truly he was never sick that doth not believe it. Then I
considered that all the medicines were compounded of herbs, roots, flowers and seeds.’ Today,
modern herbalists have developed more advanced methods of diagnosis and treatment. They differ
from conventional doctors in that they treat the body as a whole, and not just an isolated symptom. If
you ask a herbalist to cure a headache, you will not be given an aspirin. What you will be given is a
treatment based on curing the imbalances that have led to the headache developing in the first place.
Herbalists still believe in using the whole plant to treat people. Another reason is that plants are not
conveniently standardized. One type of parsley may contain more vitamin C than another and other
factors such as weather and soil conditions can affect a herb’s therapeutic value. Modern medicine
isolates chemical compounds within the plant and recreates them synthetically.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 48
Drug companies prefer to produce synthetic preparations so they can patent their formulation. It is
not possible to patent a simple plant extract as it already exists in nature, so to make their money the
drug companies must change it into something different!
Modern medicine has yet to better many of Mother Nature’s original healers, and the bases of most
modern medicines lie in herbal remedies. There are currently more than 110 prescription drugs that
are based purely on plant and herbal extracts. One of the most famous plant-healers is meadowsweet,
which was first found to contain the aspirin compound acetyl-salicylic acid. Aspirin was first
introduced in 1899 and named using the A of acetyl and SPIR from the original botanical name for
meadowsweet. There are countless other examples: steroids and cortisone were first isolated from an
East African sisal plant, meadow saffron (or autumn crocus) is the source of colchicine which is used
against gout and cancer; foxglove is the source of heart disease drugs and the woolly foxglove is
currently being used to treat cerebral malaria. Thrombosis can now be controlled by anti-coagulant
drugs developed from melilot [or sweet clover], while the opium poppy produces powerful narcotic
pain killers, including common codeine. Thorn apple is used against Parkinson’s disease and asthma,
while the poisonous belladonna extracted from deadly nightshade is used to dilate pupils in sight-
saving eye surgery. Feverfew is being successfully tested for uses in the treatment of migraine,
ginger relieves the symptoms of nausea especially morning sickness and the oil from the seeds of the
evening primrose are used to treat PMT and eczema.
Herbs are also an important part of homeopathy. This alternative medical therapy is based on the
view that a disease can be treated by small amounts of a plant or other substance that can produce
symptoms similar to the disease itself. Herbs used in common and highly effective homeopathic
remedies include arnica for shock and bruising, bryony for dry coughs and pulsatilla for hayfever or
catarrh.
The Hindu healing system called Ayurvedic medicine also relies on herbal remedies. Ayurveda
acknowledges three ‘humours’ of wind, bile and phlegm, and ancient texts describe the use of over
700 plants to treat disorders. Diet is an essential aspect of Ayurvedic medicine, which is why Indian
food uses many culinary herbs such as okra, caraway, cumin and other spices.
Herbs form an integral part of life in many cultures around the world. The Amazon Indians, who live
within some of the densest vegetation, are literally surrounded by many herbal remedies. They eat
the tuber-like roots of the yucca plant after removing the poisonous parts, make an alcoholic drink
from the fruit of the palm a valuable source of B vitamins, wash themselves with plants rich in
saponins [compounds that foam in water], and harvest tough river weeds to burn as fuel. They make
a caffeine-rich drink from the bark of the forest liana, and eyewash brewed from the leaves of this
woody vine is used to cure eye infections.
The Amazon is also the source of a potential wonder drug currently being developed to treat certain
cancers. A substance called taxol has been used to reduce the size of breast cancer tumours. It is
early days yet, but taxol is thought to work by blocking a mechanism of cell division. It is derived
from a close relation of the English yew and has been described in clinical trials in the United States
and France as one of the ‘most important advances in chemotherapy in recent times’. However, taxol
comes from the bark of the Pacific yew, an endangered species, and removal of the bark kills the
tree. Even if the plant extract is licensed there would never be enough to provide sufficient quantities
to make the drug it takes three to six trees to treat one patient and each tree takes at least sixty years
to grow before it can be used. The challenge is for the phytochemists to find other varieties of plants
that contain similar compounds, or to find a way to mimic taxol synthetically.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 49
Although the study of herbalism is as old as time, we still have a long way to go before we
understand even a fraction of what herbs and plants have to offer. Fewer than 5 percent of an
estimated 250-500,000 plant species have actually been examined for pharmacological activity.
Modern medicine is only just beginning to investigate the scientific and medicinal properties of
many forgotten plants that were used by healers in the past. As we discover more about the benefits
of these exotic species we are likely to see an increasing use in herbal remedies and continue to
benefit from their many powerful properties.
Hypocrites may be known today as the father of medicine, but for centuries pride of place in
medieval Europe was given to Galen, a 2nd-century physician, who wrote extensively about the four
“humours” – blood, phlegm, black bile and yellow bile – and classified herbs by their essential
qualities: as hot or cold, dry or damp.
These theories were later expanded by 7th-century Arab physicians such as Avicenna, and today
Galenical theories continue to dominate Unani medicine, practised in the Muslim world and India.
Galen’s descriptions of herbs as, for example, “hot in the third degree” or “cold in the second” were
still being used well into the 18th century.
HERBS IN PAPYRI
Surviving Egyptian papyri dating back to around 1700 BC record that many common herbs, such as
garlic and juniper, have been used medicinally for around 4,000 years. In the days of Ramesses III,
hemp was used for eye problems just as it may be prescribed for glaucoma today, while poppy
extracts were used to quieten crying children.
THE GREEK CONTRIBUTION
By the time of Hippocrates 468-377 BC, European herbal tradition had already absorbed ideas from
Assyria and India, with Eastern herbs such as basil and ginger among the most highly prized, and the
complex theory of humours and essential body fluids had begun to be formulated. Hippocrates
categorized all foods and herbs by fundamental quality – hot, cold, dry or damp – and good health
was maintained by keeping them in balance, as well as taking plenty of exercise and fresh air.
Pedanius Dioscorides wrote his classic text Dc Materia Medica in around 60 AD, and this remained
the standard textbook for 1,500 years. Dioscorides was reputed to have been either the physician to
Anthony and Cleopatra or, more prosaically, an army surgeon during the reign of the Emperor Nero.
Many of the actions Dioscorides describes are familiar today: parsley as a diuretic; fennel to promote
milk flow; white horehound mixed with honey as an expectorant.
ROMAN REMEDIES
The Greek theories of medicine reached Rome around 100 BC. As time passed, they became more
mechanistic, presenting a view of the body as a machine to be actively repaired, rather than
following the Hippocratic dictum of allowing most diseases to cure themselves. Medicine became a
lucrative business with complex, highly priced herbal remedies.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 50
Opposing this practice was Claudius Galenus, who was born in Pergamon in Asia Minor and was a
court physician to the Emperor Marcus Aurelius. Galen reworked many of the old Hippocratic ideas
and formalized the theories of humours. His books soon became the standard medical texts not only
of Rome, but also of later Arab and medieval physicians, and his theories still survive in herbal
medicine today.
THE ARAB WORLD
With the fall of Rome in the 5th century, the centre of Classical learning shifted East and the study of
Galenical medicine was focused in Constantinople and Persia. Galenism was adopted with
enthusiasm by the Arabs, and merged with both folk beliefs and surviving Egyptian learning. It was
this mixture of herbal ideas, practice and traditions that was re-imported into Europe with the
invading Arab armies.
Probably the most important work of the time was the ‘Canon of Medicine’, by Avicenna. This was
based firmly on Galenical principles and by the 12th century had been translated into Latin and
imported back into the West to become one of the leading textbooks in Western medical schools.
NORTH AMERICAN TRADITIONS
The first European Settlers arriving in North America brought with them the familiar healing plants
from home: heartsease and plantain, also known as “white man’s foot” because it was soon found
growing wherever the settlers penetrated. They also absorbed some Native American healing
traditions, discovering new herbs such as boneset, purple coneflower, goldenseal and pleurisy root.
Several of the American tribes also made great use of sauna-like sweat houses, and the idea of heat
as a healing technique was adopted by Samuel Thomson. This melding of traditions bore fruit in the
Physiomedical and Eclectic schools, which were later, imported into Europe and had a lasting
influence on European herbal practices.
MAGIC & MEDICINE
Native American herbalism was shamanistic – it centred on the activities of the medicine man, or
shaman. Through the use of drums and rattles and the smoking of mixtures of tobacco or peyote, the
shaman would enter a trance-like state that enabled him to “spirit travel” and seek out the soul of the
sick person in order to rescue and heal it. Today, shamans in South America use vine extracts just as
Siberian shamans were once able to “travel” by taking fly agaric toadstool or European witches to
“fly” with the help of deadly nightshade, henbane, thornapple or mandrake.
The Native Americans also made ritual use of the medicine wheel, and assigned animal totems to the
four cardinal directions; they also equated these with different personality types, spiritual energies,
diseases and plant medicine. Typically, for example, the South was symbolized by the coyote and the
energies of growth and compassion, while the eagle and the powers of wisdom and enlightenment
were symbols of the East.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 51
PHYSIOMEDICALISM
Before land battles with the plains tribes decimated the indigenous population, the early pioneers and
Native Americans shared much of their herbal lore with each other. An early enthusiast was Samuel
Thomson, who founded the Physiomedical movement. Born in New Hampshire in 1769, Thomson
learned his craft as a child from Widow Benton, a “root and herb doctor” who combined Native
American skills with the traditional role of “herb wife”.
Thomson believed that parents were responsible for both their own and their children’s health, and
patented “Thomson’s Improved System of Botanic Practice of Medicine”, a mixture of handbooks
and patent remedies which swept America in the early 19th century. Thomson’s principal theory was
that “all disease is caused by cold”, which in the bitter New England winters may well have been
accurate. By the late 1830s, he claimed three million followers.
MAINTAINING BALANCE
Central to the Physiomedical view was the belief that it is possible to strengthen the body’s “vital
force” by keeping both tissues and nervous state in balance. The key therapeutic treatment involved
relaxing or astringing tissues, and then stimulating or sedating nerves. Suitable herbs, classified as
either stimulating or sedating, relaxing or astringing, were used to achieve this balance. Irritable
bowel syndrome, for example, might be treated with chamomile to sedate the nervous system and
relax the digestive tissues, followed by an astringent like agrimony and a stimulant such as ginger in
order to encourage the vital force and internal energy levels once more.
ECLECTICISM
Other “botanic” systems followed, among them the Eclectic school founded by Dr. Wooster Beech in
the 1830s. Like the Thomsonians, the Eclectics also used herbal remedies and Native American
healing practices, but combined these with more orthodox medical techniques in their analysis of
disease. At its peak, Eclecticism claimed more than 20,000 qualified practitioners in the United
States and was a serious rival to regular medicine. The challenge ended only in 1907 when,
following a review of medical training schools, philanthropists Andrew Carnegie and John D.
Rockefeller decided to give financial support solely to the orthodox medical schools.
THE MOVEMENT IN EUROPE
Thomsonian Physiomedicalism was brought to Britain in 1838 by Dr. Albert Isaiah Coffin, who set
up a similar “system” of patent remedies and do-it-yourself guides to diagnosis. Wooster Beech
followed in the 1850s to preach his Eclectic message, and the movement took hold in working-class
areas of the country, remaining popular, in the North especially, until well into the 1930s.
In 1864, the various groups merged to form the National Association of Medical Herbalists. The
association continues to thrive today – the oldest formalized body of specialist herbal practitioners in
Europe.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 52
Although extracts such as essential oils, have been prepared from various plants for centuries,
traditional herbalism has always combined herbs to modify effects, viewing the whole as greater than
the parts. The move to identify the individual active ingredients and use these as single drugs began
in the 18th century, and many thousands are now known. These chemicals display quite different
properties from the original herbs.
Initially, these drugs could only be obtained from plant extracts but later the chemical structures of
many extracts were identified and the drugs are now made synthetically. In the transition from the
use of crude plants to clinical pills, modern medicine has lost the art of combining herbs to modify
toxicity and of using whole plants, which themselves contain chemical ingredients that can reduce
the risk of side effects.
DRUGS FROM PLANTS
One of the first modern drugs to be isolated from a plant was morphine, first identified in 1803 by
Friedtieh Serturner in Germany. He extracted white crystals from the erode opium poppy. Similar
techniques soon produced aconirine from monkshood, emetine from ipeeacoanha, atropine from
deadly nightshade, and quinine from Peruvian bark. All of these compounds, categorized as
alkaloids, are extremely potent, and could only be obtained from the raw plants until scientists were
able to synthesize them.
SYNTHESIZED SUBSTANCES
The breakthrough came in 1852 when saliein, identified as one of the active ingredients in willow
bark, was artificially synthesized for the first time. This was later modified to be less irritant on the
stomach, and acetylsalicylic acid was launched in 1899, as aspirin, by the drug company Bayer. In
less than 100 years, plant extracts have filled pharmacists’ shelves. There are many ephedrine
preparations from ma hiang, for example, both prescription and over-the-counter, which are mainly
used for coughs, catarrh, hay fever or asthma. Pilocarpinc, obtained from jaborandi, is used for
treating glaucoma; vincristine, from the Madagascar periwinkle, is used for leukaemia; while
strophanthin from Stropkaitkus kombe, found in tropical Africa and used to tip poison arrows, is
taken for severe heart problems.
CHEMICAL POWER
Extracted chemicals can often be extremely potent, and can cause effects that were unknown when
the whole plant was used. Indian snakeroot, for example, has been used for centuries in Ayurvedic
medicine for a range of ailments including snakebites, anxiety, headaches, fevers and abdominal
pains. Mahatma Gandhi reputedly drank snakeroot tea at night if he felt over-stimulated. In the West,
snakeroot was valued as a potent tranquillizer and was used for high blood pressure; it was also
prescribed in the treatment of schizophrenia and psychosis.
In 1947, scientists extracted the alkaloid resperine from snakeroot and began marketing the drug
Serpasil as a cure for hypertension. However, resperine has unfortunate side effects that include
severe depression and the abnormal slowing of the heartbeat. By the 1960s, the herb had been
restricted to the status of a prescription-only drug in Britain and its use by herbalists is thus
effectively banned. To this day, however, snakeroot continues to he widely used in other parts of
Europe and Asia, taken by many as a soothing tranquilliser.

Today’s categorization of plants as herbs, vegetables, fruits and even “weeds” is a recent invention.
To the 17th-century cook, cabbage, carrots and cucumbers were all “kitchen herbs” just as marigolds
or marjoram were. We often forget, too, that the active constituents, such as alkaloids or saponins, in
herbs” are not confined to the plants we label as such; fruits and vegetables can also be both
therapeutic or, in excess, damaging. Past cultures have classified foods by temperature or taste,
matched to the body’s needs to maintain balance: Hippocrates noted that fresh foods “give more
strength” because they are more alive, while Tibetan medicine regards frozen foods as colder and
more mucus-forming than their fresh originals.
Classifications of foods
Hippocrites first classified foods into hot cold, dry or damp categories in around 420 BC. Galen and
others later expanded these ideas into a complex classification in which many foods were considered
to belong to more than one category: apples, for example, were both cold and damp.
THERAPEUTIC FOODS
Galen and his followers labelled not only what we term “herbs” as hot or cold, dry or damp, but
“foods” as well. In the Galenical system, meat tended to be heating, fish was damp, fresh beans and
apples cold and moist, wheat generally hot and moist, and so on.
Galen and his followers labelled not only what we term “herbs” as hot or cold, dry or damp, but
“foods” as well. In the Galenical system, meat tended to be heating, fish was damp, fresh beans and
apples cold and moist, wheat generally hot and moist, and so on.
Food intake was considered to have a direct action on the four humours: blood, phlegm, yellow bile
and black bile. For example, eating too many cold, moist foods would encourage the phlegmatic
humour, and this could lead to catarrh. Too many hot, dry foods, on the other hand, encouraged the
choleric humour (yellow bile), with resulting liver or skin problems. The medieval housewife would
automatically balance the character of different ingredients, cooking fish with “hot and dry” fennel,
or adding pepper to “cold and moist beans, and she would have been quite appalled at the thought of
serving strawberries in the middle of winter, as we are able to do now: such a cold fruit would
inevitably lead to stomach chills if eaten at such a time. Today we have lost sight of this sense of
balance, eating foods regardless of climate.
From food are born all creatures, which live upon food and after death return to food. Food is the
chief of all things. It is therefore said to be the medicine of all diseases of the body.
After the Fall of Rome, European herbal traditions were not completely submerged by the ensuing
Dark Ages. The “barbarians” brought with them their own herbal healing customs to add to the
Roman practices that survived and, with the spread of Christianity, there was considerable exchange
of both actual medicines and tried-and-tested remedies. Throughout the Middle Ages, the Church
played a significant role both in cultivating physic gardens and in introducing new herbs. With the
advent of the printing press, Classical knowledge spread from the confines of the cloister to
complement the folk medicine and household herbal remedies passed through the generations.
Master Herbalist (Phytotherapy) Diploma Course – Assignment One – Page 54
ANGLO-SAXON HERBALS
Europe’s oldest surviving herbal written in the vernacular, The Leeck Book of Bald, dates from the
first half of the 10th century, and includes remedies sent by the Patriarch of Jerusalem to King
Alfred. Numerous treatments are described for ailments caused by “flying venom” and “elfshot”,
thought to be responsible for a wide range of sudden or wasting illnesses. Among the most popular
herbs in Saxon times were wood betony, vervain, mugwort, plantain and yarrow, taken in many
internal remedies but more often worn as amulets to ward off the evil eye. Although medical schools
spread through Europe (the most famous, at Salerno, was founded in the early 10th century and
taught the Hippocratic principles of good diet, exercise and fresh air), healing and herbalism were
largely in the hands of the Church, with all monasteries growing physic herbs and tending the sick as
part of Christian duty. Healing was as much a matter of prayer as medicine, and early herbals
frequently combine religious incantations with infusions, concluding that with “God’s help” the
patient would be cured.
PARACELSUS
As learning moved away from the cloister, emphasis was gradually again given to the healing skills
and disciplines once taught at the Salerno school. By the 1530s, Paracelsus [born Philippus
Theophrastus Bombastus von Hohenheim. near Zurich in 1493] was revolutionizing European
attitudes to health care. As much an alchemist as a physician, he insisted on lecturing in German
instead of the usual Latin. He regarded most apothecaries and physicians as crooked conspirators
intent upon milking the public; condemning the complex and often lethal purgatives they prescribed,
he urged a return to simpler medicines inspired by the Doctrine of Signatures.
Illustrated Herbals
HERBAL WARFARE
Paracelsus was followed by physicians such as William Turner, who wrote in English so that “the
apothecaries and old wives that gather herbs” would understand which plants physicians really meant
by their Latin prescriptions, and would not put “many a good man by ignorance in jeopardy of his
life”. Nicholas Culpeper 1616-54 was later to adopt a similar view, earning the wrath of the newly
formed College of Physicians by translating their Pharmacopoeia into English so that ordinary
people could find herbal medicines in the hedgerows instead of paying vastly inflated apothecaries’
bills. The battles between physicians, apothecaries and “herb wives” raged through the 17th and 18th
centuries as medicine came more and more under the control of the academic physicians, with their
university training, while the apothecaries strictly regulated dispensing. The emphasis was on
