The soursop (Annona muricata) is a broadleaf flowering evergreen tree native to Mexico, Venezuela, Central America, the Caribbean and northern South America, Colombia and Brazil. Soursop is also native to sub-Saharan African countries that lie within the tropics. It is in the same family as the pawpaw.
Its flavor has been described as a combination of strawberry and pineapple with sour citrus flavor notes contrasting with an underlying creamy flavor reminiscent of coconut or banana.
In many countries, people use the bark, leaves, root, and fruits of this tree for traditional remedies.
The active ingredient is thought to be a type of plant compound (phytochemical) called annonaceous acetogenins.
People have been promoting the consumption of soursop as a means to kill cancer cells.
The claim is that soursop works better than chemotherapy as some cancerous cells are resistant to chemo treatments.
