ETHNOPHARMACOLOGICAL RELEVANCE: There is very limited information regarding plants used by traditional healers in Rangamati, Bangladesh, for treating general ailments. Current study provides significant ethnopharmacological information, both qualitative and quantitative on medical plants in Rangamati. AIM OF THE STUDY: This study aimed to collect, analyze and evaluate the rich ethnopharmacologic knowledge on medicinal plants in Rangamati and attempted to identify the important species used in traditional medicine. Further analysis was done by comparison of the traditional medicinal use with the available scientific literature data. MATERIALS AND METHODS: The field survey was carried out in a period of about one year in Rangamati, Bangladesh. A total of 152 people were interviewed, including Traditional Health Practitioners (THPs) and indigenous people through open-ended and semistructured questionnaire. The collected data were analyzed qualitatively and quantitatively. This ethnomedicinal knowledge was compared against the literature for reports of related uses and studies of phytochemical compounds responsible for respective ailments. RESULTS: A total of 144 species of plants, mostly trees, belonging to 52 families were identified for the treatment of more than 90 types of ailments. These ailments were categorized into 25 categories. Leaves were the most frequently used plant parts and decoction is the mode of preparation of major portions of the plant species. The most common mode of administration was oral ingestion and topical application. Informant consensus factor (Fic) values of the present study reflected the high agreement in the use of plants in the treatment of gastro-intestinal complaints and respiratory problems among the informants. Gastro-intestinal complaint had highest use-reports and 3 species of plants, namely Aegle marmelos (L.) Corr., Ananas comosus (L.) Merr., and Terminalia chebula (Gaertn.) Retz., had the highest fidelity level (FL) of 100%. Asparagus racemosus Willd. and Azadirachta indica A. Juss. showed the highest relative importance (RI) value of 1.86. According to use value (UV) the most important species were Azadirachta indica A. Juss. (2.48) and Ocimum sanctum L. (2.45). CONCLUSION: As a result of the present study, we recommend giving priority for further phytochemical investigation to plants that scored highest FL, Fic, UV or RI values, as such values could be considered as good indicator of prospective plants for discovering new drugs. Also counseling of THPs should be taken into consideration in order to smooth continuation and extension of traditional medical knowledge and practice for ensuring safe and effective therapy.
