Medicinal and Aromatic Plants
• Forests - main source of the raw materials for Ayurveda, Siddha and Unani medicines. • IUCN Red Data book – Due to unsustainable
collections from the forests.• Promoting cultivation of medicinal plants.• Directorate of Medicinal and Aromatic Plants Research
(DMAPR)/Indian Council of Agricultural Research (ICAR).• The Department of AYUSH/National Medicinal Plants
Board (NMPB).
Some Important Medicinal Plants
• Ashwagandha (Withania somnifera Dunal)• JA 20 and JA 135 - important high yielding varieties available for cultivation.
• Safed musli (Chlorophytum borivilianum Santapu& Fern.)• JA 405 is the high yielding variety available for cultivation.
• Guggal (Commiphora wightii (Arn.) Bhandari• Tinospora (Tinospora cordifolia Miers ex Hook f. & Thoms.)• Satavary (Asparagus racemosus)• Kalmegh (Andrographis paniculata Nees)• Isabgol (Plantago ovata Forsk.)
• GI 1, GI 2, GI3, JI 4, HI 5 and Niharika are available for cultivation.• Senna (Cassia angustifolia Vahl)• Aloe (Aloe barbadensis Mill)• Periwinkle (Catharanthus roseus (L) G.Don)
Guggal Commiphora wighti (Arn.) Bhandari
Guggal• The oleo-gum-resin is of importance in international
trade• Extracted at unsustainable rates, causing declines• Guggal gum - is a mixture of 61 % resins and 29.3 %
gum.• Guggulosterol and guggulosterone are the important
active ingredients of the gum resin.• The oleo-gum-resin of guggal is highly effective in
the treatment of obesity, arthritis and several other diseases in Indian System of Medicine.
Guggal - Oleo-gum-resin• Oleo-gum-resin is
present in the ducts of paranchymatous bark.• Near the base of the
tree, an incision is made at a depth of about half the thickness of the bark.• Oleo-gum-resin oozes
from the cut and gets solidified to brownish yellow.
Guggal Cultivation: Method and Practices
• Practiced spacing under cultivation: 3 x 3 m2
• Tapping of the tree: November – January • Collection: Until June
• Growth and development under different plant population densities• 1, 4, 6, 11 plants/m2 [30x30, 40x40, 50x50, 1x1
m2]• Yield and production of oleo-gum-resin• 6, 12 & 12 months after planting

Guggal – Plant Population Density
• Thickness of the stem range was 12 – 14 mm at 6 months after planting (MAP). However, at 12 MAP and 18 MAP, the stem thickness increased to 22 – 31 mm.
• The stem thickness (83 mm) and heavy stem (80 g) was found in 1 plant/m2 density as no much competition per unit area when compared to other treatments.
• When compared among the treatments, higher dry matter was partitioned into stems in T4 (71%).
• When guggal is tapped, it yielded 4 g/m2 at 44% tapping success whereas, T1 and T2 yielded 187 g/m2 and 120 g/m2 at 28% and 19% tapping success (higher density of plantation).
• The plant population density and the stem characters like thickness and weight can be effectively used for the successful tapping of guggal for higher ole-gum-resin production per unit area under commercial cultivation.
