Byrsonima crassifolia
Central American and Caribbean fruit tree; bark and leaves used for digestive conditions, diarrhea, and skin infections in traditional medicine.
Nance (Byrsonima crassifolia) is a Central American and Caribbean fruit tree whose bark and leaves are traditionally used for diarrhea, skin infections, and digestive conditions. Its pharmacological activity is attributed to high levels of tannins, catechins, epicatechin, quercetin, and ellagic acid, which confer astringent, antimicrobial, anti-inflammatory, and antioxidant properties. Modern research supports these uses, though clinical evidence remains limited (Evidence Level C).
The primary mechanism of Nance bark and leaves involves tannins (e.g., ellagic acid) and flavonoids (catechin, epicatechin, quercetin) that bind to proteins in the gut mucosa, forming a protective layer and reducing peristalsis, thereby alleviating diarrhea. These compounds also inhibit bacterial growth by disrupting cell membranes and chelating iron, while quercetin and catechins modulate inflammatory pathways such as NF-κB and COX-2, reducing local inflammation. Additionally, the antioxidant activity of ellagic acid and flavonoids scavenges reactive oxygen species, supporting tissue repair in skin infections.
