Guanábana (Soursop) [facts]

More studies are needed on this amazing plant’s medicinal possibilities, but the delicious fruit is safe to eat, nutritious, and low in calories…but don’t eat the seeds.

Soursop (español: guanábana) is the fruit of Annona muricata, a broadleaf, flowering, evergreen tree native to the tropical regions of the Americas and the Caribbean. It is in the same genus, Annona, as cherimoya and is in the Annonaceae family. The soursop is adapted to areas of high humidity and relatively warm winters. With an aroma similar to pineapple, the flavor of the fruit has been described as a combination of strawberries and apple with sour citrus flavor notes, contrasting with an underlying thick creamy texture reminiscent of banana.

The delicious fruit is safe to eat and nutritious, but the seeds are toxic and should not be consumed. Soursop is typically eaten raw by cutting the fruit in half and scooping out the flesh. Fruits range in size and can be quite large, so it may be best to divide it into a few portions. Some studies have shown that the plant’s active ingredients possess antioxidant, anticancer, anticonvulsant, anti-arthritic, anti-parasitic, anti-malarial, liver protective and anti-diabetic effects. The uses of guanábana in herbal medicine and research into its potential for cancer treatment are of interest, but medicinal uses of the fruit or its parts should be done only with the supervision of a reliable health professional.

In traditional herbal medicine, the fruit and leaves of the tree are used to relieve digestive ailments (including diarrhea), pain, hypertension, inflammation, fever, coughs, and asthma, among many other medical afflictions. The leaves and fruits contain natural compounds that could potentially be beneficial for prostate as well as other cancers, although more scientific studies are needed. Graviola / Soursop extracts have a promising potential for treating gastric ulcers. A study showed that an alcohol-based extract of soursop possessed antiviral activity.
