The medicinal plants used by a female folk medicinal practitioner (FMP) practicing in Kumartek village in Narsingdi district, Bangladesh was documented since the FMP claimed that folk medicinal practice runs in her family for generations and that she learned medicinal uses of plants from her father. The FMP was observed to use a total of 21 plants distributed into 17 families for therapeutic purposes. The various diseases treated included helminthiasis, bone fracture, gastrointestinal disorders, pain, rheumatic fever, respiratory tract disorders, diabetes, jaundice, and dizziness. Both monoherbal and polyherbal formulations were used by the FMP. The plants used by the FMP offer opportunities to researchers for further studies leading to better and more affordable drugs.
