Description

Ice cream-bean, also known as joaquiniquil, cuaniquil, guama or guaba, is a fruit native to South America. It is in the mimosoid tribe of the legume family Fabaceae. It is widely grown, especially by Indigenous Amazonians, for shade, food, timber, medicine, and production of the alcoholic beverage cachiri. It is popular in Peru, Ecuador, Pernambuco-Brazil, Venezuela and Colombia. The taxonomic name Inga is derived from its name with the Tupí people of South America, while the species name edulis is Latin for "edible". The common name "ice-cream bean" alludes to the sweet flavor and smooth texture of the pulp.

Characteristics:

Mature trees of Ice cream-bean reach 30 m (98 ft) high and 60 cm (2.0 ft) diameter at breast height, usually branching from below 3 m (9.8 ft). The branches form a broad, flat, moderately dense canopy. Inga edulis can be evergreen in tropical regions or deciduous when planted in colder regions. The tree has a pale grey coloured trunk. The stems and young twigs can be sparsely to densely haired. The leaves are alternate, evenly pinnate, 10–30 cm long with 4–6 pairs of opposite, dark-green, membranous, slightly pubescent, oval leaflets. The terminal leaflets can grow up to 18 cm long by 11 cm wide in comparison to the basal ones. Extrafloral nectaries are placed on petioles and stipules can be either inconspicuous, absent, or caduceus.

Medicinal Uses:

Ice cream-bean is widely used in native South American folk medicine. Decoctions of the leaves, bark or root commonly are utilized as treatments for diarrhea, arthritis and rheumatism. Crushed, boiled leaves are ingested to relieve coughing or applied to lip sores, possibly caused by herpes. Several studies have investigated Inga edulis as a source of polyphenols for use as antioxidants and have shown promising results. However, further studies are necessary to test and develop medical applications.
