摘要:The purpose of this research was to study the medicinal species Siparuna guianensis Aublet (negramina) in the riverside community of Bom Sucesso, a small location in the municipality of Várzea Grande, Mato Grosso. We conducted interviews using a semi-structured questionnaire containing a set of closed-ended and/or open-ended questions. We concluded that the main form of preparation was the decoction of the leaves used as a topic bath to relieve the symptoms of the flu, such as fever and body pain, and we detected that this knowledge is not being handed down to new generations.
