Ethnobotanical study of medicinal plants of Sirjan in Kerman Province,Iran

Ethnopharmacological relevance

From ancient time human beings have used different plants, animals and minerals to prevent and treat various diseases. In this respect, plants have been of particular importance. Ethnobotany is the science of reviewing how indigenous people and local tribes have used their regional plants for particular purposes such as treating diseases in the past. The information gathered from such studies can help to improve national health systems and even lead to the discovery of new medicines. Keeping this in mind, in this study a survey of Sirjan area ethnobotany was conducted during 2011–2012.

Materials and methods

At the beginning, thirteen local people were interviewed about their region?s medicinal plants and their consumptions. These plants were collected and identified using identification keys. The data collected was analyzed using quantitative value indices F_IC, RFC and CI.

Result

Many plants collected have medicinal properties and have been used by local people to treat various ailments. Of these plants, nineteen families, 37 genera and 43 species belonged to medicinal plants. Among them, Lamiaceae with 8 species and Malva L. with 3 species were the largest medicinal plant families and genera, respectively. These plants are often used as decoction (28%) and as powder (21%). Also, the fruit of these plants are used most often. Besides being used as medicinal plants, they have other uses such as food, fuel, etc. Malva sylvestris has the largest value of relative frequency of citation and cultural importance indices. The most ailment categories have the highest level of informant agreement (mean F_IC=0.92).

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.
