Soursop is the fruit of Annona muricata, a broadleaf, flowering, evergreen tree.It is grown in some areas of Southeast Asia, as well as in some Pacific islands. 

The flavour  of the fruit has been described as a combination of strawberry and pineapple, with sour citrus flavour notes contrasting with an underlying creamy flavour reminiscent of coconut or banana.

The plant is grown as a commercial crop for its 20–30 cm (7.9–12 in) long, prickly, green fruit. which can have a mass of up to 15 lb (6.8 kg), making it probably the second biggest annona after the junglesop.

The flesh of the fruit consists of an edible, white pulp, some fiber, and a core of indigestible, black seeds. The species is the only member of its genus suitable for processing and preservation. The sweet pulp is used to make juice, as well as candies, sorbets, and ice cream flavorings.

Nutritionally, the fruit is high in carbohydrates, particularly fructose.The fruit also contains significant amounts of Vitamin C, Vitamin B1 and Vitamin B2.

Preliminary In Vitro laboratory research suggests that Graviola may have potential to treat some infections.
