Background and Purpose: Ethnopharmacology has been one of the important sources for drug discovery from ancient times. The principles of ethnopharmacology research include compiling a list of plants used by an ethnic group and explaining how these plants are utilized by individuals. Basht and Gachsaran regions in Kohgiluyeh and Boyer-Ahmad Province, residence place of Bavi tribe, are the habitat of different plant species that used for therapeutic purposes.
 
Materials and Methods: Information was obtained via interviews and questionnaires from eleven local healers. Subsequently, the plant samples mentioned by local healers were collected by a researcher and identified by a botanist. The results were arranged in tables based on therapeutics uses, plant families, part of plant used, route of administration, and disease categories according to the 2019 International Classification of Diseases.
