Graviola (Annona muricata), also known as Soursop, is a small evergreen tree that is native to the Amazon Rainforest and other tropical areas of the Americas. It produces a large, heart shaped edible fruit that is 15 to 23 cm in diameter, is yellow-green in colour, and has a white flesh. In Brazil, the juice is a popular drink, and is known as Guanábana.
A number of active compounds have been identified in all main parts of the plant - including the leaf, bark, root, stem, fruit and seed.
Graviola vegicaps contain a powder extract made from the concentrated juice of the Graviola fruit. See also Graviola powder and Graviola teabags.
