Soursop tea is not a “tea” in the traditional sense and is not made from the leaves of the Camellia sinensis plant, like black tea or green tea. It is brewed using just parts of the soursop plant.
Soursop trees are native to tropical areas in North and South American. The soursop fruit is a large green oval or heart-shaped fruit with thorny skin. Some sources describe the fruit as having a musky taste, while others compare the taste to that of a banana or a papaya. People use the fruit to make juice, smoothies, ice cream, and other sweet treats.
Soursop is also called graviola, so the drink may also be referred to as graviola tea. Other names for soursop include guanabana, custard apple, and Brazilian paw paw.
