INTRODUCTIONMan is known to have utilized plants as a source of medicinal drugs for thousands of years. Medicinal plants are potential sources of new drugs and hold a great value for developing pharmaceutical products, phytomedicines, and dietary supplements (King et al. 1999; Hoang et al. 2008). About 80% of the world’s population relies on traditional medicine, especially in remote areas in developing countries, medicinal plants may form the only available source of health care (Van Andel 2000; Hoang et al. 2008). Knowledge of medicinal plants, as once embedded in numerous indigenous cultures, is rapidly disappearing. Year by year, the total sum of human knowledge about the species, distribution, ecology, management, and extraction of medicinal plants is declining: the continuation of a process of loss of local cultural diversity that has been underway for centuries (Hamilton 2003, Hoang et al. 2008). Although in many communities medicinal plants are the only available source for medical treatment, local indi-genous remedies are less used now than before. In many tropical regions indigenous knowledge is at risk of extinction just as is biodiversity itself (Slikkerveer 1999, Van Andel 2000, Hoang et al. 2008). Vietnam is a rich country of biodiversity, which has the high potential of medicinal plants. According to scientists, Vietnam has about 4000 plant species are used as medicinal sources (Tap 2007). This source is not only diverse in number of species but also diverse in the treatment capability. However, until now, people knowledge of these species is limited, there are many more medicinal plant species in nature that people do not know or just a small part of it applicability (Dien 2007). Ba Vi National park, one of the 30 National Park in Vietnam was established in 1992 (the National park belong to Ha Tay province before 2009, and now it belongs to Hanoi when Hanoi expended area). The health care situation in the research area of Ba Vi National Park is generally much less favourable. Because most people living in and around the park is still poor. To study indigenous knowledge of Muong and Dao ethnic minority groups in Ba Vi National Park, this study deals with the variety of medicinal plant species and their uses recorded during 6 months survey of traditional medicinal plants in that area. The main research questions with regards to the use of medicinal plants were: - Which plant species are being used for which disease? - Which medicinal plant species are being commercialized in the research area? - What are different between traditional knowledge of Muong and Dao ethnic minority groups in Ba Vi National Park on using medicinal plants. - What is the present role of medicinal plants in the health care system of the indigenous communities? We hope that the documentation of this medicinal plant knowledge contributes to the conservation of both cultural diversity and plant biodiversity in Vietnam in general and Ba Vi National Park in particular.
METHODOLOGYHousehold surveys and interviews were carried out in 100 randomly selected households. The standard interviews contained specific questions on age, gender, and ethnic background of the gatherers and main users of plant products. Additionally we organized the trips with indigenous experts, e.g., traditional doctors, village elders and other local people who knew about medicinal plants to determine which plant species are harvested and for what purpose in the forests. These trips were also used to collect voucher specimens for further identification of the harvested plants. We also did market inventories in local markets to determine the price of the medicinal plant products that are for sale. All plants that were considered by local people to have medicinal properties were collected and identified. These plants not only included wild species but also cultivated plants and wild plants that had been taken from the forest and planted in gardens. The specimen was deposited at the Biodiversity centre of the Vietnam Forestry University. The importance of medicinal plant species was identified using standard Participatory Rural Appraisal (PRA) techniques (Ngai 2001) where local people were asked to rank a list of regularly used local medicinal plants. STUDY AREABa Vi National Park was established in 1992. A core zone area about 3000 ha, and buffer zone of approximately 15,000 ha. Flora of the Park has about 800 plant species, belong to 427 genera and 98 families. Out of them 13 local endemics species, 10 species listed in the Vietnamese Red Data Book for rare and endangered plants. There is a population of some 46,000 people, belonging to Kinh, Muong and Dao groups living in the Park. Of them, Kinh (Viet) is the major group, Dao and Muong are ethnic minority groups and they constitute the major users of Medicinal plants in the Park and depend on harvesting of natural resources. This study focuses on traditional medicinal plants are defined and used by two this ethnic groups.
