COLUMBIA, Mo. ¬— Described as a hotspot of botanical diversity, there are more than 20,000 indigenous plant species in South Africa. Several thousand of them are used by traditional healers every day in that country for treating a range of problems from the common cold to serious diseases such as AIDS. How safe and effective these treatments are will be the focus of The International Center for Indigenous Phytotherapy Studies (TICIPS), a collaborative research effort between the University of Missouri-Columbia and the University of the Western Cape, South Africa. The center will be funded by a $4.4 million, 4-year grant from the National Center for Complementary and Alternative Medicines (NCCAM), a division of the National Institutes of Health.
