The Kumaon Himalaya of Uttarakhand is rich in floristic composition. It is a land of diverse cultures and ethnic groups. Traditionally the folk people utilize the vegetation of their ambient environment in the form of different products as food, fuel wood, fibre, fodder, timber, medicine, etc. During ethnobotanical explorations of different forest divisions in this region, the authors collected a large number of information on local plants which are used as folk drugs for treatment of a wide range of health related problems. This study has also yielded information on some medicinal plants that are becoming scarce in the area due to overexploitation, unsustainable harvesting practices and loss of habitat. A review of literature revealed that most of these plant species find use in Unani medicine for treating various non- communicable diseases (NCDs). Hence, an attempt has been made to highlight such species in this report. For each plant species are given the correct botanical and vernacular names, habit and habitat, the part used, medicinal use(s) and other observations. The threat of extinction of these useful and commercially viable medicinal plants has been discussed and also the strategies for their conservation have been suggested.
