Plants have been used since ancient times for the treatment of various ailments.

The traditional healers are dwindling in number and there is a grave danger of the younger generation is not interested to carry on this tradition. Therefore it becomes the responsibility of the scientific community to unravel the information and to document it for availability to the whole world for the benefit of human beings. The present study was initiated with an aim to identify traditional healers who are practicing herbal medicine among the tribals in Muthanga forest range of Wayanad Wildlife Sanctuary, Kerala, India and quantitatively document their indigenous knowledge on the utilization of medicinal plants, particularly most common ethnomedicinal plants.
