Botanical Overview
Scarlet Runner Bean (Phaseolus coccineus) is a species in the Fabaceae family. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 30 compounds in this species, suggesting potential medicinal value.
