Botanical Overview
Guaba (Inga edulis) belongs to the Fabaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. 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.
General Description
It is in the mimosoid tribe of the legume family Fabaceae. It is widely grown, especially by Indigenous Amazonians, for shade, food, timber, medicines, and production of the alcoholic beverage cachiri. It is popular in Peru, Ecuador, Pernambuco-Brazil, Venezuela, Guyana, Costa Rica and Colombia. The taxonomic generic name Inga is derived from its name with the Tupí people of South America (ingá) while the specific name edulis is Latin for “edible”. The common name “ice-cream bean” alludes to the sweet flavor and smooth texture of the pulp.
