The study aimed to conduct an ethnobotanical survey of medicinal plants and their uses in the municipality of Cocal, located in the state of Piaui. The methodology used was the "snowball" technique to identify interviewees through conversations with friends, neighbors, family members, the Agriculture Department, and the Rural Workers' Union. Questionnaires containing objective and descriptive questions about the cultivated plant species, the parts used, preparation methods, and diseases treated with the plants were applied. Twenty interviews were conducted, with 80% of the respondents being female. The age range of the interviewees varied from 18 to 85 years. Information was collected on 32 medicinal species, with the most cited being Boldo (Plectranthus barbatus). The most used part of the plant was the leaf, and the most common form of consumption was tea (decoction). Medicinal plants were sought by the interviewees to treat illnesses, mainly general pain, flu, and fever. In conclusion, the municipality of Cocal presents the possibility of increasing the production of medicinal plants, and the knowledge and use of these plants are important for the local community in treating different health conditions.
