BORGES, C.C. et al. Bidens pilosa L. (Asteraceae): traditional use in a community of southern Brazil. Rev. bras. plantas med. [online]. 2013, vol.15, n.1, pp.34-40. ISSN 1516-0572.

The correct use of plants for therapeutic purposes requires selection of those showing efficacy and safety based on the popular tradition and/or scientific validation. Bidens pilosa L. is a species that widely occurs in tropical regions and is known in Brazil as "picão-preto". Four agents from the Health Pastoral Service were identified in the region of Criciuma, Santa Catarina State, for their popular knowledge of Bidens pilosa. The study was conducted by means of interview which provided data concerning the knowledge of "picão preto", handling, used plant part, plant/solvent proportion, preparation methods, administration route/dosage, indication and restrictions. The pharmaceutical form, as well as the posology, was significantly variable. Analysis of the collected data showed anti-inflammatory action as the main therapeutic indication.

Palavras-chave : medicinal plant; Bidens pilosa L.; popular knowledge; anti-inflammatory action.
