Chidambaram College, Tuticorin 628008, Tamil Nadu Received 3 October 2003; revised 22 March 2004 Tribals are a distinct ethnic group who are usually confined to definite geographical areas, mainly in forests. Their life is woven around forest ecology and forest resources. Information on some very useful medicines known to the tribal communities through experience of ages is usu- ally passed on from generation to generation. Ethnomedicinal surveys and fieldwork are impor- tant for systematic documentation. In the present attempt, the ethnomedicinal aspects of 45 spe- cies of plants used by the Paliyan and Pulayan tribes of lower Palni Hills (both northern and southern slopes) Tamil Nadu have been enumerated.
