Farmacopeia natural de comunidades rurais no Estado do Piauí, Nordeste do Brasil

Abstract

The purpose of this work is to know more about medicinal plants, forms of usage and therapeutic indications determined by the communities of Pau-Arrastado, Salinas and Resolvido. We used semi-structured interviews, guided tours and followed the usual botanical methodology. The study sample included 93 individuals (51.9% of the total). Species were grouped into 18 categories of disease, according to the World Health Organization (WHO). We calculated the Factor of Informant Consensus (FIC) and the Index of Relative Importance (IRI). They included eighty-one (81) species, belonging to 40 botanical families and 69 genera were referred, of which 75.3% were native ones. The most prominent family was Fabaceae (18.5%), and the leaves were the most used parts (32%). The preparation method most used was dye (38.2%). The highlights were the body systems: agents of bacterial and viral infections (27.2%), digestive system diseases (22.4%) and genitourinary diseases (19.5%). Croton campestris A. St. Hil. and Ximenia americana L. were the most versatile with an IRI of 2.00. There was a greater consensus for the plants indicated for the treatment of liver diseases.
