BackgroundThis study documents the use of medicinal plants from the Mustang district of the north-central part of Nepal. Traditional botanical medicine is the primary mode of healthcare for most of the population of this district and traditional Tibetan doctors (Amchi) serve as the local medical experts.MethodsField research was conducted in 27 communities of the Mustang district in Nepal from 2005-2007. We sampled 202 interviewees, using random and snowball sampling techniques. After obtaining prior informed consent, we collected data through semi-structured interviews and participant-observation techniques. Voucher specimens of all cited botanic species were deposited at TUCH in Nepal.ResultsWe recorded the traditional uses of 121 medicinal plant species, belonging to 49 vascular plant and 2 fungal families encompassing 92 genera. These 121 species are employed to treat a total of 116 ailments. We present data on 58 plant species previously unknown for their medicinal uses in the Mustang district. Of the medicinal plants reported, the most common growth form was herbs (73%) followed by shrubs, trees, and climbers. We document that several parts of individual plant species are used as medicine. Plant parts were generally prepared using hot or cold water as the 'solvent', but occasionally remedies were prepared with milk, honey, jaggery, ghee and oil. Amchis recommended different types of medicine including paste, powder, decoction, tablet, pills, infusion, and others through oral, topical, nasal and others routes of administration.ConclusionsThe traditional pharmacopoeia of the Mustang district incorporates a myriad of diverse botanical flora. Traditional knowledge of the remedies is passed down through oral traditions and dedicated apprenticeships under the tutelage of senior Amchi. Although medicinal plants still play a pivotal role in the primary healthcare of the local people of Mustang, efforts to ensure the conservation and sustainable use of medicinal species are necessary.

Background: The district of Manang (2000 -6000 m) is located in the Central Himalayas, Nepal. The majority of local inhabitants of the area are Gurungs, of Tibetan origin. The remoteness of the region has resulted in continued use of plants as medicine in an area where the ethnobotany has sparsely been documented.

Despite new advances in modern medicine, the cultural use of plant in traditional medicine continues from ancient time to this day all over the world. The present research seeks to explore ethnomedicinal plants used by the local people of Nawalparasi district for primary healthcare. Local healers were interviewed regarding the detail uses of plants. When convenient a jungle or forest walk was also conducted, accompanying local healers for plant collection and detailed information gathering. A rich and unique diversity of 94 ethnomedicinal plant species belonging to 49 families under 86 genera were documented. In Nawalparasi, the expense of modern medical treatment combined with the poor economic status of indigenous people and a strong belief in the traditional medicine and traditional medical practitioners are the main reasons for the persistence of the traditional healing system. In addition, we have also documented a lack of continuation and flow of indigenous knowledge from the elders to the younger generation. Youth tend to be attracted by the wave of modernization and do not appreciate the importance of conservation of traditional knowledge. The use of plants in Nawalparasi is an old tradition and the exploration of such unique cultures should be completed thoroughly so that the oral traditions are not lost forever. Immediate conservation and management approaches of valuable medicinal plants with the involvement of local indigenous people of Nawalparasi district will encourage the sustainable conservation of both biological and cultural diversity.Key words: Traditional medicine; Local healers; Healthcare; Conservation; NawalparasiDOI: 10.3126/on.v7i1.2555Our Nature (2009) 7:82-99

Plant diversity plays an important role in maintaining the world's foods demands. Even today in Manang, a remote, mountainous district within the Annapurna Conservation Area, Nepal, local people gather substantial amounts of wild plants to meet their daily nutritional needs, with several species also used for trade. There has been little documented regarding the use of these wild foods, which play a part in both daily nutrition, and survival during times of famine. Moreover, planning for development, land use, economic growth and biodiversity conservation has not taken them into account. Information about edible wild plant use was gathered by interviewing knowledgeable villagers over a period of five years (2002-2006). In total, 41 plant species were used as sources of fruits, juice, vegetables, and achar (local relish or pickle). Several wild food plants that need intensive processing before consumption were documented, including the calcium oxalate containing Arisaema species. The traditional knowledge of use of wild food plants is decreasing in many parts of the world with the introduction of modern packed food items and Manang is not the exception. The results of this research will help to play a catalytic role to encourage dialogue among the people of Manang, and national and international scientific communities regarding long term bioprospecting research, and shape the creation of a rural livelihood strategy. Analysis of the nutritive and health values of some of these edible plant species may encourage the scientific community to build partnerships with local community to work towards long term sustainable utilization and conservation.
