Abstract 
An account of 58 medicinal plant species used by local people of Dunai, Juphal, Suu, Sahartara and Majphal villages of Dolpa district is given. Greater numbers of species were found to be used in fever (17 spp.) and diarrhea & dysentery (17 spp.). Roots and rhizomes of 29 species; leaves of 27 species; and stem and barks of 17 species were mostly used. Juice, raw items, paste and decoction of plant species were the common method of usages. The ethnomedicinal contribution from Nardostachys grandiflora 'Vulte', and Neopicrorhiza scrophulariiflora 'Katuko', each for eight ailments was important. Local people have adequate knowledge on ethnomedicine, while ethnomedicinal plants are under threat due to habitat destruction and over exploitation, indicating an urgent need for conservation of species and their habitats and indigenous knowledge as well. Key words: Ethnomedicine, Dolpa, ailments, parts used, group discussion
Resumen

Introduction 

The art of use, treatment and prevention of disease is pre historic (Gill & Ogbor 1997) noticeably in south Asia (Bawa & Godoy 1993). About 80% of the world's population depends wholly or partially on traditional medicine for its primary health care needs (Wambebe 1990). Nepal is an excellent repository of cultural heritage for diverse ethnic groups and it has a rich tradition of folk practices for utilization of wild plants (Manandhar 1993). Rural people have used plants particularly wild for fulfilling their subsistence needs (Bhattarai 1992) and treating disease since time immemorial. About 70-80% rural population depends on traditional medicine for health care (Manandhar 1980). Bhattarai (1988) and Justice (1981) reported that when modern health care fails, the patient frequently turns to use of indigenous health care. It is evident that indigenous system of health care is mostly the first choice as well as last resort of Nepal (Bhattarai 1998). Understanding the local people's indigenous knowledge in relation to biodiversity/resource management is one of the key issues for the development today (Kunwar & Duwadee 2003). However, due to changing perception of the forest dwellers, commercialization and socio-economic transformation all over the world, there has been a general observation that the indigenous knowledge on resource use has degraded severely (Gadgil et al. 1993; Silori & Rana 2000).
Recognizing these facts, of late, efforts have been made in Nepal to document such knowledge that has accumulated through a long series of observations, interactions and practices with and of local people and thus contains important information relevant to sustainable use of medicinal plant resources. Over the last three decades, intensive ethnomedicinal surveys have been carried out among the rural and tribal population in different parts of the world, however, such studies started in Nepal since 1990. Information on the ethnomedicinal plants of Dolpa is lacking and the work related to medicinal plants and ethnic groups, culture etc. has not been carried out so far. Hence, an attempt has been made to collect information on ethnomedicinal uses by the local people in Dolpa district, Nepal.




Materials and Methods 


Dolpa, the largest but the least developed and remote district lies in mid-western region of Nepal. Most of the hills are naked, open and dry due to low rainfall (450-850 mm), dry air, and severe anthropogenic interference like firing, over-grazing, over exploitation, deforestation, slash and burn agriculture, etc. (Kunwar 2002). The district ranges from as low as sub tropical (1575m) to as high as nival zone (6883m) and extends between 27 21' 27 40' north longitude to 84 35' 84 41' east latitude. This physical intersection coupled with other abiotic factors such as geology, soil and climate has allowed supporting many endemic, threatened, ethnobotanically and economically useful medicinal plants and unique trans-himalayan ecosystems. Some noteworthy medicinal plants, which are more valued, include Cordyceps sinensis 'Jibanbuti', Morchella conica 'Mathyaura', Nardostachys grandiflora 'Vulte', Valeriana jatanmansi 'Samayo', Taxus wallichiana 'Kandelotto' etc. The major ethnic groups/castes in study area are 'Kshetri', 'Dangi', 'Rokaya', 'Shahi', 'Budha', 'Thakuri', 'Thakulla', 'Brahmin', 'Karki', 'Shrestha', 'Sherpa', etc. They are Indo-Aryan and Tibeti-Burmans, speaking Nepali, Tibetan and Kham (Tibetan dialect), being involved in cultivation of wild rice (Chino), wheat, buckwheat (Phapar), potato, etc. in less fertile land. Due to low productive soil, most of them rely upon wild medicinal plants for the subsistence. They are engaged particularly in collecting medicinal herbs and raw food items as part of their traditional ventures.


Ethnomedicinal notes of plants being used by local people were recorded in July 2001 and May 2003 at 'Dunai', 'Juphal', 'Suu', 'Sahartara' and 'Majphal' villages of Dolpa district. Group discussions, field observations, informal interviews, institutional survey, etc. were used as tools under participatory rural appraisal. Checklist was also made and asked to gather the information. Altogether, 15 group discussions (GDs), three in each village, were carried out. Participants for checklist survey, group discussion and crosschecking were local people: layman, collectors, farmers, traders, leaders, elderly people, traditional healers, witch doctors and Amchis. The information was further verified by crosschecking and validated by the common response from all villages on same species treatment. The plants were identified comparing with authentic specimens at Tribhuvan University Central Herbarium (TUCH) and housed in TUCH.



Results and Discussion 

Fifty-eight plant species belonging to 42 families and 56 genera are listed in alphabetical order by their scientific names along with their family name; followed by vernacular names; location from where specimens recorded and collected; and uses. Of 42 families, Rosaceae was important in terms of ethnomedicinal contribution.
Of total 45 types of ailments recorded, diarrhea & dysentery and fever were indigenously treated with use of the most number of plant species (17). Contribution from 16 species was for curing cough & cold. It was followed by cuts & wounds and bleedings treated from 14 species. In terms of parts used, roots and rhizomes were used most (29 species). Leaves of 27 species; stems and barks of 17 species; flowers, fruits and inflorescence of 15 species; seeds of five species; and wood, resin and whole plant of five species were reported to be used. Juice, raw items, paste and decoction of 21, 20, 19, 18 medicinal plant species respectively were used to treat ailments indigenously.
Species wise contribution to ethnomedicine in Dolpa district was highest for Neopicrorhiza scrophulariiflora 'Katuko' and Nardostachys grandiflora 'Vulte' each for eight ailments, followed by Plantago major 'Sajaino', and Valeriana jatanmansi 'Samayo' each for seven ailments. However, N. grandiflora is most vulnerable (Ghimire et al. 2005b). The uses of Cedrus deodara oil in skin diseases and respiratory troubles, raw rhizome of Dactylorhiza hatagirea as tonic, ripen fruits of Ephedra gerardiana to control blood pressure and Hippophae salicifolia as appetizer were important. Dolpa district is rich in medicinal herbs and indigenous knowledge. However, the knowledge is constricting within the few healers and medicinal plants are less available. Human impact has been considered an important factor in Dolpa in structuring the resources available nearby (Kunwar and Sharma 2004). The plants are under threat due to habitat destruction and over exploitation. Premature harvesting and over harvesting of tradable medicinal herbs was eminent posing serious threats (Ghimire et al. 2005a). High demand of Nardostachys oil in world market has also led un-sustainable harvesting. An urgent need, therefore, for conservation of species as well as their habitats and indigenous knowledge, is required (Agrawal 2002; Ghimire et al. 2005b). Medicinal tree species Taxus wallichiana and Cedrus deodara are in great peril due to overexploitation as thatching material and furniture respectively.
