Uses of invasive alien plant species:
Medicine
Ornamentals
Fire wood
Food
Schinus molle L.
Invasive alien plant species
Aim
Investigate the use of invasive alien plants for medicinal purpose by
traditional healers in Capricorn district, Limpopo Province.
Objectives

Materials and Methods
Distribution map showing Capricorn district municipality.
Cont..Materials and Methods
Ethnobotanical survey
The permit was obtained from traditional councils.
Snowball method (Convenience sampling method) resulting in 30healers being interviewed.
Data collected via a semi-structured questionnaire and guided fieldwork with traditional healers. .
Plant collection
Collected invasive plants were identified using literature andspecimens at Larry Leach Herbarium.
Voucher specimen of the plants were prepared and depositedat the university herbarium.

Conclusions
Traditional healers use invasive plant species in the study area tocombat various ailments.
Antifungal activity and phytochemical studies.
Awareness of invasive alien plant species for the traditional healers inthe study area.
Therefore, there is a need for careful consideration of IAPs that areused medicinally as they face eradication measures as part of SouthAfrican management strategy.
