From Folk Medicine to Pharmacology: A Systematic Review of the Anti-Inflammatory Evidence for Hymenaea spp. (Fabaceae)

Hymenaea spp. (Fabaceae) are widely used in folk medicine to treat fatigue, inflammation, respiratory, and gastrointestinal disorders. However, comprehensive evidence-based evaluations of their pharmacological potential remain limited. This systematic review brought together the existing pharmacological and phytochemical evidence on the significant therapeutic potential of Hymenaea spp. A total of 17 studies were included; phytochemical analyses identified flavonoids, triterpenes, procyanidins, xyloglucans, and caryophyllene oxide among the major bioactive constituents. The reported biological activities were primarily anti-inflammatory, antioxidant, immunomodulatory, antimicrobial, and antiproliferative. Mechanistic findings consistently substantiated anti-inflammatory evidence through COX/LOX inhibition, cytokines, and redox-related modulations. Despite these promising results, the molecular mechanisms and translational evidence remain poorly defined. In conclusion, Hymenaea spp. exhibit significant pharmacological potential. Future studies integrating metabolomics and preclinical and clinical validation are essential to translating traditional knowledge of this species into evidence-based therapeutics.
