“…In medical systems based on herbalism, folklore, or shamanism, however, no written documents exist, and the herbal formulations used are often kept secret by the practitioners, making the information more difficult to access (Brusotti et al, 2014;Fabricant and Farnsworth, 2001). Depending on the herbs to be studied, information can be acquired from different sources, including books on medical botany (e.g., Lewis, 2003), herbals (e.g., Adams et al, 2012), review articles on medicinal plants used in a certain geographic region or by an ethnic culture (e.g., Gairola et al, 2014), field work (e.g., Kunwar et al, 2009), and computer databases (Leonti, 2011;Ningthoujam et al, 2012).…”
