[email protected] Abstract: The study of the relationship between man and nature can reveal the potential of plant resources. In the present study we used non-probabilistic sampling and snowball technique in communities of the Soure Marine Extractive Reserve-Pará, namely, Caju-Úna Community, Céu Settlement, and Pesqueiro Village, in order to analyze the medicinal plants used by these peoples, focusing on the diversity, consensual use and cultural importance of species, and providing ethnopharmacological information available in the scientific literature. To this end, participant observation, semi-structured interviews and free lists were used, as well as ethnobotanical indices and scientific studies retrieved from databases. We identified 90 species, among which Ruta graveolens, Maytenus obtusifolia and Libidibia ferrea stood out. The species were distributed in 50 families, mainly Lamiaceae, Asteraceae and Fabaceae. The most frequent diseases treated with these plants, mainly with preparations in the form of teas, were flu, inflammations and stomach problems.
