Psidium guineense
Small tree native to tropical America used in folk medicine across Brazil and the Caribbean for diarrhea, dysentery, and wound healing.
Psidium guineense is a tropical tree native to the Americas, traditionally used in Brazil and the Caribbean for diarrhea, dysentery, and wound healing. Its leaves contain bioactive compounds such as quercetin, guaijaverin, tannins, and essential oils, which contribute to its antidiarrheal, antimicrobial, and anti-inflammatory properties. Current evidence is limited (Level C), primarily from in vitro and animal studies, supporting its traditional uses.
The antidiarrheal effect is mediated by tannins and flavonoids that inhibit intestinal motility and secretion, possibly via modulation of opioid receptors and reduction of cAMP levels. Antimicrobial activity against enteropathogens is attributed to essential oils and quercetin disrupting bacterial cell membranes. Anti-inflammatory actions involve inhibition of cyclooxygenase (COX) and lipoxygenase (LOX) pathways, as well as suppression of pro-inflammatory cytokines like TNF-α and IL-6, primarily due to quercetin and guaijaverin.
