Abstract

The paper enumerates the traditional uses of 73 plant species belonging to 62 genera representing 47 families, which are used by the village communities of Kali Gandaki, Bagmati, and Tadi Likhu watersheds of Nepal for the treatment skin diseases. Some of useful species are under serious threat due to unsustainable activities. Hence, a proper documentation of useful plants with their present status and local traditional knowledge as well as practices is urgently needed. Effort should also be initiated to implement appropriate conservation measures for preservation and sustainable uses of these useful species.

Introduction

The rural communities of Nepal are still dependent upon wild plants for their primary healthcare and treatment of diseases. They collect the useful plants from various habitats such as forests, scrub, grassland, cultivated fields and use these plant materials as raw drugs. These communities have acquired good knowledge on the useful and harmful properties of the useful plant resources in course of their constant association with forest and agro-ecosystems. However, at present, this vast store of information is being eroded as a result of human’s unsustainable activities. The loss of traditional knowledge within cultures undergoing rapid change is just as irreversible as the loss of species (Joshi and Joshi, 2005). Hence efforts should be made to document the various uses of plants before some of these plants are eliminated from the area, or before these inhabitants shift over to modern remedies. In this context, the rich and diverse forest ecosystems and vast tribal population with traditional knowledge systems due to cultural and environmental diversity in the country have attracted a number of workers for ethnomedicinal studies in the past (Acharya, 1996; Bhattarai, 1992; Chaudhary, 1994; Coburn, 1984; Joshi, 1988; Joshi, K. 1991; 1996; 2000; 2003a & b; 2004a & b; 2005; Joshi and Edington, 1990; Joshi and Joshi, 2000; 2005; Joshi, Shrestha and Joshi 2003; Manandhar, 2002; Phole, 1990; Sacherer, 1979; Taylor, Manandhar and Towers, 1995; Toba, 1975). However, the vast store of ethno-medicinal information of these study areas have not been fully documented.

In the present paper an attempt has been made to present indigenous knowledge and uses of the wild plants which are used by local communities for treatment of skin diseases.

The study is carried out in some villages of Kali Gandaki, Bagmat and Tadi Likhu Watersheds of Nepal. The land forms of the study areas are characterized by moderate to steep sloppy mountainous terrain. The study areas are endowed with rich and varied vegetation types due to their diverse topography and variable climatic conditions. The human pressure on these vegetative resources is very heavy except on very steep, almost vertical and inaccessible rock faces near the river. The villages are inhabited by different ethnic tribes which are rich in folk lore.

Materials and Methods

Several field trips in and around the study areas were undertaken during the years 2004-2006 with a view to collect plant species of ethnomedicinal value and to document the indigenous practices. The information was gathered using various techniques such as open and structured interview, and discussion with local informants, such traditional healers / “jkankri”, and experienced village elders including midwives and by direct observations on the way different plant materials were being collected and used (Joshi and Edington, 1990). The plant specimens were identified with the help of floras. Voucher specimens are deposited in the Botany Department, Patan Campus, Tribhuvan University, Kathmandu, Nepal.

Enumeration of Plants

During the field survey, ethnobotanical information of 73 species of medicinal plants belonging to 47 families was compiled from various habitats of the study areas. The study shows that among the skin diseases, scabies, wounds, and boils are the major diseases in the villages. During the treatment of the diseases, various forms of preparation are used. In the following enumeration, the species are arranged alphabetically. Botanical name followed by family, Nepalese name, uses of the plants and their parts as reported by the local inhabitants, and habitat along with the information collected areas.
