The Garos were once a nomadic tribe of the Bodo group of Mongoloids now living in different areas of Bangladesh and in the adjacent states of India. Garos are very conservative in their outlook. Among Garos, the people who treat and cure patients with folk medicines are considered persons with supernatural power and therefore, enjoy respect and honor in the community. These persons are named k hamal or k a mal. Khamals usually possess a very good knowledge of the properties of medicinal plants, which because of the forest regions that they inhabit, can be very diverse in nature. We undertook an ethnobotanical survey among the Garo tribal healers to gather information on ailments that are common amongst the Garos and the medicinal plant formulations, which are used to treat these ailments. Detailed information was collected from the healers as to plants, ailments, formulations, and dosages. The names of 65 plants distributed into 43 families were obtained from the tribal healers inhabiting the Madhupur region in Bangladesh.
