Soursop is the fruit of the Annona muricata or graviola tree. It is used commercially in foodstuffs. Cancer-fighting properties have been identified in the fruit, but these properties have not yet been tested on human subjects.
Soursop has a distinctive flavor typically used in the production of juice, candy, sorbet and ice cream. The flavor is described as a combination of strawberry and pineapple. The trees it is harvested from are native to Mexico, the Caribbean, and Central and South America.
The fruit has been promoted as an alternative cancer treatment. However, the United States Federal Trade Commission determined that there was no credible scientific evidence that the extract of soursop can prevent, cure, or treat cancer of any kind, as of 2015.
