Indian Journal of Traditional Knowledge Vol. 10(2), April 2011, pp. 281-286 Indigenous knowledge and uses of medicinal plants in Macchegaun, Nepal Kunjani Joshi1*, Ranju Joshi2 & AR Joshi2 1 Department of Botany, Patan Multiple Campus, Tribhuvan University, PO Box 2486, Kathmandu, Nepal; 2SchEMS, Pokhara University, Nepal E-mails: kunjanijoshi@hotmail.com; ranjujoshi@hotmail.com, ajoshi9@gmail.com Received: 27.11.2008; revised: 29.04.2010 Based on a field survey, 87 species belonging to 54 families, used by the local people of the Macchegaun, Kathmandu district, Nepal are reported. Local people have remarkable detailed knowledge of species identity, characteristics and their specific uses. These traditional knowledges and practices are disappearing particularly due to unplanned land use change and over-explotation of the species. Some species are under serious threat indicating urgent need of documentation of useful plants with their uses and indigenous practices. An attempt has also been made to recommend some conservation measures for preservation and sustainable uses of these species.

Cl.8: A61K36/00, A61P1/02, A61P1/10, A61P1/14, A61P1/16, A61P5/00, A61P9/14, A61P11/00, A61P17/00, A61P19/00, A61P29/00, A61P31/00, A61P35/00, A61P39/02 The rural communities depend heavily on plant diversity for the fulfillment of their basic needs and conservation of other natural resources. They collect useful plant resources from various habitats and utilize them using indigenous knowledge and practices. The vast store of information on indigenous knowledge, practices and technologies is being eroded as a result of fast urbanization, over-exploitation of resources, unscientific land use, change of lifestyles and behavior1. Hence, priority ought to be given to document the useful plants with indigenous knowledge, practices as well as technologies from the area before the inhabitants shift over to modern lifestyle. In Nepal, very little works relating to the documentation of useful species and their uses to improve livelihood, and their roles for conservation and sustainable management of environmental resources have been carried out1-5. There are still gaps on the comprehensive study and documentation relating to the ethnobotanically useful species and indigenous knowledge, practices and perception of the local people for sustainable resource management. Moreover, as Nepal is also one of the signatories of the conventions (Ramsar Convention, Biodiversity Convention, and Convention on International Trade in Endangered Species), priority should be given to the —————— *Corresponding author documentation the useful species with their sustainable uses, and existing local level indigenous knowledge, techniques and practices. The study is designed to fill up the gaps and to recommend some strategies for sustainable management of the resources. Methodology The ethnobotanical study was carried out in the Macchegaun and surrounding areas. Macchegaun is located in the Southwest part of the Kathmandu valley and lies in the lap of Chandragiri mountain range where it is extended Southnorth longitudinally. The landforms of the study areas are moderate to steep slopey mountainous terrains with temperate climate. The physical ecological factors are suitable for the development of rich and varied vegetation with various ecosystems. The southern part of the village was covered by the forest with important species such as Pinus roxburghii (salla), Lyonia ovalifolia (angeri), Schima walliiichii (chilaune), Castanopsis indica (thulo katus), Castanopsis tribuloides (musure katus), Quercus lanata (banjh), Q. semicarpifolia (khasru), Prunus cerasoides (painyu) and the animals like tiger, fox, leopard, deer, etc. The Community Forest Committees (Macchenarayan Forest User Committee and Chundevi Forest User Committee) manage the existing forests. 282 INDIAN J TRADITIONAL KNOWLEDGE VOL 10, No. 2 APRIL: 2011 Macchegaun has 9 wards with 2,963 total population. The study area is inhabited by different ethnic groups (Newar, Magar, Khhetri, Brahamin, Sunuwar, Tamang, Mijar, etc.), with rich in traditional knowledge and practices. Agriculture is the main occupation of the villagers, who depend on natural resources for their livelihood. Several field trips in and around the study areas were undertaken during the July–Dec 2005 and Feb–May 2006. Ethnobotanical information was gathered mainly through repeated interview and open-ended participatory discussions with local informants, such traditional healers/ jkankri, teachers and experienced village elders including midwives and by direct observations on the way different plant materials were being collected and used6,7. The taxonomic identity of the plants was determined with the help of local floras. Voucher specimens are deposited in the Biodiversity and Environmental Monitoring Laboratory of SchEMS, Pokhara University, Kathmandu, Nepal. Results and discussion During the field survey, ethnobotanical information of 87 species of plants belonging to 54 families have been collected from various habitats of the study area (Table 1). Among the documented medicinal species, the family Asteraceae was most frequently represented with a total of 7 species, followed by Euphorbiaceae (5), Amaranthaceae & Rosaceae (4 each), Ericaceae, Fabaceae, Fagaceae & Solanaceae (3 each) and others with less than 3 species. Though these species are distributed in various habitats, most of the species are mainly confined to the forests. The data on the medicinally important plants indicte that 27 species were used to treat gastrointestinal disorders, 16 for fever, cough and headache, 15 illnesses of the skeleton- muscular system, 12 for dermatological illness, 7 for genito-urinary complaints, 7 for respiratory aliments, 6 for dental problems, 2 for cardiovascular complaints and disease of blood, 2 for opthalmological problems and 28 for others. The people in the vicinity of the forest have a good knowledge of useful plant species especially the knowledge on medicinal plants. Traditional beliefs and practices are deeply rooted in their culture in such a way that they attribute most of the complicated ailments and other misfortunes to supernatural origin due to soul loss, spells or curses cast by evil spirits by the displeasure8. The local people use the plants and their parts for the treatment of ailments following the traditional practices. The most popular medicinal preparation are infusion, decoction, paste or juice. The medicinal uses of the same species may vary from one village to the next village. For example, the decoction of leaf of Swertia chirayita is given to relieve stomach disorder and fever in the study areas, whereas in the the villages of the Makalu Barun area the Sherpa people use the leaves for the treatment of cuts and wounds. In Barmoche village of Sindhupalchok district, juice of Swertia chirayita root is taken to cure liver diseases and paste of leaves prepared with mustard oil is applied over boils and scabies9,10. Similarly, juice of Lyonia ovalifolia leaf is drink for curing the ringworm by Tamangs in Raitar village, Nayapati village Development Committee, Kathmandu district, while the decoction of leaves of the plant is used to get relief from pain in the study area11. This may be due to diversity in culture, tradition and isolation of one area to other. This knowledge is, however, being eroded with introduction of modern medicines. During the survey, the uses of medicinal plants by local communities were analysed. Among the local communities of the study area, 71% of the senior people and 56 % of new generation used medicinal plants and their products to cure various ailments. The preferred species are Acorus calamus, Aloe vera, Aegle marmelos, Artimisia indica, Azadirachta indica, Centella asiatica, Eupatorium adenophorum, Ficus benghalensis, Gaultheria fragrantissima, Jatropa curcas, Justicia adhetoda, Pinus roxburghii and Swertia chirayita. However, the use of medicinal plant was limited to the minor health related problems such as cuts, wounds, gastrointestinal problems, fever, headadch, cough, etc. When questioned about the changing status of the existing useful plants, the respondents listed some important species, such as Acorus calamus, Centella asiatica, Justicia adhatoda, and Swertia chirayita, which have also declined in abundance during the last decade. During the last few years, some initiatives have been taken for the sustainable management of medicinal plants and their resources12-19. Despite the implementation of various activities for the conservation of the species and documentation of the species, there is still gaps in policy, plan and implementation of programs, capacity building activities in an integrated manner.

Therefore, appropriate national policy, action plan and program related to the conservation and sustainable uses of the plants should be formulated taking into consideration both the needs of the people and sustainable management of resources. Many parts of the biogeographical areas of the country still remained unexplored. Hence, it is strongly recommended that major thrust should be given to an intensive inventory and documentation of useful species, their chemical constituents, habitats, and potential utilization as raw materials. The study indicates that there seem to be a good potential for their sustainable utilization. Therefore, emphasis should be given to implement some pilot programmes for plantation, domestication and cultivation of useful species . This will help in providing additional income INDIAN J TRADITIONAL KNOWLEDGE VOL 10, No. 2 APRIL: 2011 286 to local people. The people of these villages have comprehensive knowledge about plants and their potential uses. The traditional knowledge should be documented and conserved. Moreover, top priority should be given to in-situ conservation of the species. Such steps will not only contribute to protect the habitats but also help to maintain the ecological processes. Emphasis should also be given to conserve the habitats and useful species in ex-situ conservation. Attempt should be made to launch special programmes for raising people's awareness about conservation and utilization of species. 6 Acknowledgement Authors are thankful to the inhabitants of the study areas for their kind cooperation and help during the field survey.
