Abstract The local people of the Kali Gandaki and Bagmati watersheds of Nepal nurture rich knowledge about ethnobotanical plants of their surroundings. In the course of the survey of the useful plants, 22 species have been documented which are being used for dental and oral healthcare.
Key Words: Ethnobotanical plants; healthcare; traditional practices.
Introduction: The rural people of Nepal rely on plant resources for their domestic and primary health care needs. They collect the useful plants and their parts from various habitats such as forests, scrubs, grasslands, cultivated fields, wetlands and riverbanks and use them following traditional practices. During the survey of the ethnobotanical plants of Nepal, the authors have also collected and documented some ethnobotanical plants used for dental and oral healthcare with the objectives of documentation of the useful species and their indigenous uses before some of these are eliminated, or before the inhabitants of the watersheds abandon their traditional practices. Although some works relating to this area have been already carried out by Acharya (1996); Bhattarai (1992); Joshi (1988); Joshi and Edington (1990); Joshi and Joshi (2000, 2005); Joshi, Shrestha and Joshi (2003); Manandhar (2002); and Panthi and Chaudhary (2003), the vast store of ethnobatanical information with traditional knowledge and practices have still not been comprehensively documented. In the present paper, an attempt has been made to enumerate the species which are being used by local people of some villages of the Kali gandaki and Bagmati watersheds to cure dental and oral problems.
Materials and Methods Ethnobotanical survey was conducted in the villages: Ramdi, Balam, Beltari, Mirmi, Ridi, Syalbas and in the surrounding areas of the Kali Gandaki watershed and Okharni, Mulkhadka, Sundarijal, Chaubas and surrounding areas of the Bagmati watershed. The studied area showed diverse physical, biological as well as ethenic features. Ethnobotanical information was collected using various methods, such as RRA, PRA, direct interviews and discussions with local people.
Results and Discussion During the field survey, ethnobotanical data of 22 species belonging to 13 families were gathered from various habitats of the study areas and each was documented with regard to its local name, part used, collection, mode of administration and habitats of the species. The prevalent oral health problems in these watersheds are dental caries and periodental diseases (gingivitis and pyorrhoea) and sores. In the following enumeration, the species are arranged alphabetically. Botanical name followed by family, local name, plant part used and mode of utilization.

The present study reveals that the study areas are rich in useful plant diversity and the inhabitants have remarkable detailed knowledge of species identity and uses of the plant resources. The present trend of urbinization of the study areas also indicate that in spite of establishment of small western styled health centers in the area, uses of plants and traditional practices will continue to play a significant role in the socio-cultural life of these village communities. Prior to loss of these potential species and erosion of indiginous knowledge, efforts should be made to document useful species and the vast stores of indigenous ethenobotanical knowledge and practices. It will be also deserable to carry out chemical constituents of the plants and their pharmacological effects on the treatment of diseases in order to validate these plant resources as alternative drugs.
