- Graviola, or soursop, is a small, upright evergreen tree that is native to tropical South and North America. The tree produces a large, heart-shaped, edible fruit that is sold commercially.
- All parts of the graviola tree, including the fruit, juice, crushed seeds, bark, leaves, and flowers, are used in herbal medicine systems in the tropics. Graviola is mainly used as an alternative treatment for parasitic infections and cancer. It has also been used as a sedative and as a treatment for spasms. Extracts of the leaf, root, stem, and bark of graviola may also be useful to control snail species that carry schistosomiasis (a parasite).
