The use of plants as medication in the state of Piauí, Brazil, has been a common practice passed from generation to generation. This study aimed to analyze the use of medicinal plants by residents of the community Curral Velho, in the municipality of Luís Correia, northern Piauí, Brazil, contributing to register and preserve the traditional botanical knowledge of the community under study and, as a consequence, the state’s. The survey of plant species used as a therapeutic resource was conducted through interviews with a semi-structured questionnaire applied to 38 informants. The plants were collected for scientific identification. Use value (UV), informant consensus factor (ICF), and relative importance (RI) of species were determined. We registered 62 species, belonging to 38 families and 57 genera, and the Fabaceae family stood out. Aristolochia triangularis, Petiveria alliaceae, and Stachytarpheta cayennensis had the highest use values (UV = 3.0), and Turnera subulata was the most versatile. Out of the 10 bodily systems identified, those with higher concentration of medicinal species are related to the most ordinary illnesses as general signs (inflammation, fever), respiratory tract diseases, and genitourinary tract diseases. This survey enabled the identification of some relevant aspects concerning the use and knowledge of medicinal plants in the community under study. The diversity of medicinal plants known and the availability of plants in the very community suggest a correlation between use/knowledge of medicinal plants and their availability.
