This study documented traditional medicinal plant knowledge of tribes in West Bengal, India. Field studies from 1998-2001, 2011-2013, and 2014-2016 documented plants used by tribes as treatments for diseases, as antifertility elements, and for other purposes. Many sites, including Alipurduar and Cooch Behar, contained ethnomedicinal plants with multiple uses. The study provides documentation of traditional knowledge that is important for conservation and database preparation.
