Corylus jacquemontii Decne.: a promising lesser-known multipurpose tree species of the Himalayan region

The article presents an overview of Indian hazelnut (Corylus jacquemontii)- a multipurpose threatened species of the Himalayan region of high traditional importance. The species is used as a medicine, fuelwood, fodder, and timber by the resident communities of Himalaya. The edible nuts of the species are nutrient-rich and have a high market value; they are collected and sold by the local people to earn hard cash. Further, a wide range of pharmacological properties that aid in the prevention of cardiovascular diseases, diabetes, and other oxidative stress-related disorders add to the importance of the species. The recent overexploitation for diverse purposes has threatened its survival and calls for multidisciplinary efforts for the conservation of the traditionally important Indian hazelnut.
