Medico-botanical Study of Commonly Used Angiosperm Weeds of Rajshahi, Bangladesh

A. H. M. Mahbubur Rahman
Department of Botany, University of Rajshahi, Rajshahi-6205, Bangladesh

Abstract/ Executive Summary:

The current research work was designed to file the indigenous knowledge on the commonly angiosperm weeds of Rajshahi. Frequent field trips were made during 2010-2011 to record medico botanical data by interviewing local people of various age groups, mostly ranging between 20 to 70 years, including medicinal healers (herbalists/hakims). A total of 72 weed species under 62 genera of 29 families have been documented which are used for the treatment of 86 diseases/illness. For each species voucher number, scientific name, local name, family, ailments to be treated, mode of treatment and part(s) used are provided.

Keywords: Medico-botanical investigation, Angiosperm weeds, Herbal medicines, Rajshahi, Bangladesh

Location: Rajshahi district, Bangladesh

Start Date: 00-00-2010

End Date: 00-00-2011

Program Area: Development of Host and Medicinal Plants

Commodity: Medicinal Plants, Weed management

Objectives:

To explore the commonly used weeds of Rajshahi medico-botanically and to record, preserve and document the medicinal uses of these weeds before the information is lost forever.

Methodology:

The present study in based on the intensive field of the area during the period of 2010 to 2011. A total of 220 people having an age rage 20 to 70 years were interviewed using the semi-structured interviewed method (Alexiades, 1996; Martin, 1995). Professionally they were peasants, day labor, farmer, betel leaf cultivators, housewives, medicine men, small shopkeepers etc. Among them 100 were female and rest 120 were male. Regular field studies were made in the study area during the period. The information about the plants used for various diseases was gathered through interviews and discussion with the elderly people, medicine men and traditional medical practitioners were also consulted. Triangulation methods have been followed for data validation in the field (Dean and Whyte, 1959). Plant specimens with flowers and fruits were collected and processed using standard herbarium techniques (Alexiades, 1996; Hyland, 1972). Common angiosperm weeds referred by these people were authentically identified with the help of Hooker (1961), Kirtikar and Basu (1987), Khan and Huq (1975), Prain (1963) and Ahmed et al. (2007-2009). The voucher specimens are stored at Rajshahi University Herbarium (RUH) for future reference.

Achievement/Findings:

The present findings are probably the first record of medico-botanical knowledge on common angiosperm weed species for Rajshahi using standard research protocols. The present study may be a preliminary contribution to the medico-botany of this area using standard research methods, focusing on angiosperm medicinal weeds and their local uses for healthcare. This healthcare knowledge transmitted orally from one generation to generation. The study also suggested that the present information on medicinal use of weeds by local people may be used for botanical and pharmacological research in future for the discovery of new sources of drugs.
