The aim of this research is to describe and characterize the etnoknowledge about medicinal plants and their therapeutic uses in an indigenous community of the Brazilian Northeast. Semi-structured interviews were used, seeking information about the use of medicinal plants, through the Snowball method. The consensus among respondents' answers was considered to identify the most importante species for the population. 68 plant species have been reported in medical use, with predominance of native plants (55,9%). The most representative families in this research were Fabaceae (12 spp.) and Lamiaceae (10 spp.). The species that stood out with the highest number of citations were Alecrim (Rosmarinus officinalis L.), Capim santo (Cymbopogon citratus (DC.) Stapf.) and Cidreira (Lippia alba (Mill.) N.E.Brown), Alecrim was also the plant that presented more therapeutic uses. The leaves were the most used part, consumed as teas and syrups, mainly in the treatment of respiratory system diseases. The information contained in this work show the plant diversity and local culture, as well as value the ethnoknowledge of the population. This may reveal a rescue of traditional customs, of use and management, of plants with medicinal potential, for the home manipulation of low cost remedies for all the studied community.
