OLIVEIRA, F.C.S.; BARROS, R.F.M.  e  MOITA NETO, J.M.. Medicinal plants used in rural communities from Oeiras Municipality, in the semi-arid region of Piauí State (PI), Brazil. Rev. bras. plantas med. [online]. 2010, vol.12, n.3, pp.282-301. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722010000300006.

This study was performed between February 2007 and May 2008 in twenty-one rural communities from Oeiras Municipality (07º00'54''S and 42º08'06''W) located in a transition area of Caatinga/Cerrado vegetation, where Caatinga predominates. The aim was to know the plants traditionally used for therapeutic purposes by the population. The botanical harvests followed the usual methodology and the identified specimens were incorporated into the collection from the Herbarium Graziela Barroso (TEPB). As methodological procedure, semi-structured interviews by using standardized forms were done with 20 dwellers indicated by local community leaders as people presenting notorious knowledge and who accompanied the harvests. The cited species were grouped into 17 categories, according to the World Health Organization (WHO). Quantitative data were obtained by calculating the relative importance (RI) for each species and the informant consensus factor (ICF). We identified 167 ethnospecies, distributed into 59 botanical families and 143 genera, from which 65.86% were native. The most representative families in number of species were Leguminosae (28) and Euphorbiaceae (18). The most representative genera were Croton L. (9), Senna Mill. (5), Jatropha L. and Solanum L. (4). Caesalpinia ferrea Mart., Ximenia americana L., Myracrodruon urundeuva Allem. and Lippia alba L. had the highest RI values: 1.79, 1.86, 1.21 and 1.14, respectively. It must be emphasized the high therapeutic use of these species, mainly for the treatment of respiratory system disorders (56 species) and intestinal, hepatic and helminthic infectious diseases (65), from which flu and diarrhea were the most cited. The leaf is the most used plant part in the local folk medicine (31.5% of cases). The most frequently used preparation procedures are decoction (32.2% of cases) and infusion (23.8%). These data allow inferring that dwellers of rural communities have knowledge about the plants used as medicinal, especially native ones.
