Semi-structured interviews, field observations and guided field walks with informants were employed to obtain ethnobotanical data. A total of 62 key informants (26 males and 36 females) were selected purposefully with the help of local administers and local elderly people. A total of 55 species of medicinal plants which belong to 31 families were collected and identified for treating 26 human aliments.
