Although the traditional use of medicinal plants is a very widespread practice in Brazil, there are still few studies aimed at native prescribers, known as healers. The aim of this work was to catalog the medicinal species prescribed by remaining healers of the Grande Dourados region, Mato Grosso do Sul, Brazil. Semi-structured interviews were conducted with support of a standardized questionnaire for remaining healers selected using the "snowball" technique. The medicinal species selected were collected, identified, and classified according to the British National Formulary. Remaining healers were identified in seven municipalities in the region of Grande Dourados. Family, divine revelation, and participation of the Catholic Church were the most important sources of knowledge. Seventy-one medicinal species, mainly herbaceous belonging to Asteraceae, Lamiaceae, Amaranthaceae, and Verbenaceae families, were the most prescribed. Most species are used in the treatment of digestive and cardiovascular diseases, in addition to immune and respiratory diseases. Healers from the region of Grande Dourados maintain considerable ethno-knowledge about the medicinal properties of different medicinal species. Sharing this information values their culture and preserves the knowledge for future generations.
