The paper deals with 30 selected species of plants e.g. Costus speciosus (Keen.) Sm., Drynaria quercifolia (L.) J. Sm., Melastoma malabathricum L., Mimosa pudica L., Pedilanthus tithymaloides (L.) Poit., Premna latifolia Roxb., Solanum viarum Dunal, Thelypteris arida (D. Don) Morton, etc. which are used as medicine by some of the tribals like Mech, Rabha and Oraon of the Jalpaiguri District of West Bengal in their traditional system of treatment.
Ethnobotanical field study reveals some interesting information about mode of their uses of plants in various ailments either single or in combination with other plant parts. It has been observed that though these tribes are living under same environment and using the same species of plants for curing disease, their Prescriptions are quite different. This indicates that the tribes are still retaining their own tradition so far as treatments are concerned.
