title: An ethnobotanical study of medicinal plants used by ethnic people in Parbat district of western Nepal.
abstract: BACKGROUND
  Nepal, a mountainous country having diversified topographic and climatic conditions, gives rise to a wide range of flora and fauna. In villages ethnic people, including Magar and Majhi highly depend on medicinal plants for their primary healthcare. Due to overexploitation, encroachment in forest for arable land and destruction of natural habitat, potentially useful medicinal plants are going to be threatened in their natural environment. There is a strong need to enlist highly valuable medicinal plants and use traditional knowledge to protect, utilize and manage them in ex-situ and in-situ conservation. The present research investigates and documents traditional knowledge on medicinal plants utilization as natural medicine by two ethnic communities Magar and Majhi of Parbat district in Western Nepal.
  
  
  METHODS
  Ethnomedicinal data was collected during 2012-2013 by the following standard ethnobotanical methods. Data about medicinal uses of herbs, shrubs and trees were collected using semi-structured questionnaire, field observation, personal interview and group discussion with 334 (130 men and 204 women) pre-identified local informants, among which 13 male and 2 female were local healers. Statistical tool, informant consensus factors (F(IC)) and fidelity level (FL) values were used to analyze the importance of ethnomedicinal plants.
  
  
  RESULTS
  A total of 132 ethnomedicinal plant species belonging to 99 genera and 67 families have been documented. These plants are used to treat various diseases and disorders grouped under 12 disease categories, with the highest number of species (61) being used for gastro-intestinal, parasitic and hepatobiliary disorders (FIC=0.78%), followed by blood and lymphatic system (F(IC)=0.76%) category. The highest fidelity level (FL) values recorded in Paris polyphylla (FL=96.0%) followed by Bergenia ciliata (FL=95.0%) confirms that these plants are the best plant species with medicinal properties.
  
  
  CONCLUSIONS
  The two ethnic communities, Magar and Majhi, in Parbat district are rich in ethnomedicinal knowledge. The high degree of consensus among the informants suggests that current use and knowledge are still strong, and thus the preservation of indigenous knowledge would show good foresight in acting before much has been lost.
