Dwindling Ethnobotanical Knowledge of Aconitum naviculare in the Trans-Himalayan Manang Valleys of Central Nepal
摘要
Indigenous mountain communities utilize traditional knowledge of plants to meet their curative needs for various illnesses. Such knowledge is eroding due to recent socioeconomic changes. We examine traditional knowledge on distribution, harvesting practices, use patterns, and conservation of Aconitum naviculare (Bruhl) Stapf, a rare alpine plant of the Himalayas and one of the most frequently used medicinal herbs in Tibetan medicine. We surveyed 65 households and interviewed 11 key informants representing 11 villages in two trans-Himalayan valleys of the Manang district in central Nepal. According to the respondents, A. naviculare grows along with alpine scrubs on south-facing slopes. Locals use aerial parts of the plant collected during peak flowering season to treat fever, common cold, and hypertension. We found a substantial risk of loss of traditional knowledge on the use of this medicinal herb, particularly among the younger generation.
