Plantas medicinais utilizadas no tratamento de doenças dermatológicas no Brasil: diversidade de usos, populações e evidências etnofarmacológicas

The use of medicinal plants in the treatment of dermatological conditions in Brazil involves a diversity of species, traditional knowledge, and ethnopharmacological evidence. The methodology consisted of a bibliographic review and systematization of ethnobotanical and ethnopharmacological studies conducted in Brazil. Considerable floristic diversity was identified, with emphasis on Myracrodruon urundeuva, Stryphnodendron coriaceum, Cassia alata, and Aloe vera. Traditional communities use decoctions and poultices to treat wounds, burns, and dermatomycoses. Preclinical studies indicate anti-inflammatory, wound-healing, and antimicrobial activities, reinforcing the potential of herbal medicines in primary health care within the Brazilian Unified Health System (SUS).
