Ethnobotanical survey of Purulia district, West Bengal, India for medicinal plants used against gastrointestinal disorders

Ethnopharmacological relevance: An ethnobotanical survey was conducted in the remote hills, forests and rural areas of Purulia, one of the tribal rich districts of the West Bengal state of eastern India. Purulia is a part of the biogeographic zone Deccan Peninsula Chhotonagpur. The authors have reported the use of medicinal plants by nine tribes of the district against various gastrointestinal disorders. Materials and methods: Semi structured questionnaire was used during the interview with the informants having traditional botanical knowledge. Bhumijs, Birhor, Gond, Ho, Kharia, Mal Pahariya, Mundas, Oraon and Santhali represent the various aboriginal groups present in the district. The use of medicinal plants were documented using an interview data sheet mentioning the names, age, profession and gender of the informants and scientific and vernacular names, families, part(s) used, disease(s) treated, method of preparation, mode of administration of the botanicals and the preparations. Results: A total number of 56 plants belonging to 29 families have been reported to be used against different types of gastrointestinal disorders viz, indigestion, stomach pain, vomiting tendency, constipation, piles, diarrhea, dysentery, cholera, loss of appetite, liver complaints, intestinal worms etc. Fabaceae and Apocynaceae were found to be the dominant families of medicinal plants used to treat such ailments. Conclusion: Age, gender, literacy and profession of the aboriginals were found to be the significant factors when the traditional knowledge of medicinal botanicals was concerned. Due to urbanization and loss of biodiversity, the authors have noted a significant decrease in the ethnic knowledge as well as the botanicals. Preservation of folklore should be given utmost importance in this region to prevent the rapid loss of ethnobotanical wealth. (c) 2012 Elsevier Ireland Ltd. All rights reserved.
