Abstract/ Executive Summary:

Use of medicinal plants for primary health care by the local people in and around the Lawachara National Park, Bangladesh was recorded. A total of 56 plant species under 30 families with 70 formularies (treatment mode) have been documented. Among the medicinal species, Citrus limon (L.) Burm. f., C. maxima (Burm.) Merr., Cucurbita pepo L., Lepisanthes rubiginosa (Roxb.) Leenh., Euphorbia pulcherrima Willd. ex Klotz., Mimosa diplotricha C. Wright ex Sauv. have been reported as new medicinal species from Bangladesh. Out of these plant species, 39.29% belonged to herbs, 19.64% shrubs, 3.71% trees and 5.36% climbers. In majority cases, leaves of the medicinal plants were found leading in terms of their use followed by fruit, bark, stem, seed, whole plant, latex, rhizome and inflorescence.

Objectives:

The aim of the present study was to record medicinal knowledge of plants used by the local and ethnic communities living in and around the Lawachara National Park.

Methodology:

The study was carried on the local people living in and around the Lawachara National Park from July, 2009 to June, 2010. A total of 100 people (50 from Khasia community and 50 other than Khasia) having an age range 12 - 92 years were interviewed using semistructured interview method (Alexiades 1996, Martin 1995). Professionally they were peasant, day labor, betel leaf cultivators, house wives, medicine men, forest minor product collectors, small shop keepers, etc. Among them 35 were female and rest 65 were male. Triangulation method 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 (Hyland 1972, Alexiades 1996). The specimens were identified consulting Uddin and Hassan (2004), Siddiqui et al. (2007) and Ahmed et al. (2008-2009, 2008a). Specimens available at Dhaka University Salar Khan Herbarium (DUSH) and Bangladesh National Herbarium were also consulted for the identification of the collected plants which were deposited later on in the DUSH.

Achievement/Findings:

The present findings are probably the first record of ethno-medicinal knowledge for Lawachara National Park using standard research protocols. The present study may be a preliminary contribution to the ethno-botany of this area using standard research methods focusing on medicinal plants and their local uses for the health care. One ethnic group Khasia has been living within Magurchara and Lawachara Punji (slam) of the park area. In most cases they use medicinal plants for their primary health care. This health care knowledge transmitted orally from one generation to generation. No written documents were found in the area during the study period. The study also suggested that the present information on medicinal use of plants by the local people may be used for the park management plan and in ethno-pharmacological research in future for the discovery of new sources of drugs.
