ABSTRACT
Medicinal plants have been used since ancient times for the treatment of a range of diseases, and in some countries, the use of medicinal plants is often associated with witchcraft and superstition, because people did not have the scientic insight to explain and predict the curative action of plants. Herbal medicine is still a central part of the some medical systems, such as Ayurvedic medicine in India and traditional Chinese medicine (TCM) in China, and in several developing countries.
