Also known as Graviola tea or pawpaw tea, soursop tea is derived from the leaves of the soursop plant, taxonomically known as Annona muricata. Native to the tropical regions of the Americas, the fruit of this plant can weigh more than five pounds, but to prepare the tea only the leaves are required. This fruit has received a great deal of attention in recent years due to its apparent effects on cancerous activity in the body, but research is still ongoing for safety and efficacy of this tea. These effects of soursop are attributed to the presence of alkaloids, acetogenins, antioxidants, vitamin A, vitamin B, vitamin C, calcium, iron, potassium, gentisic acid, and anonol.
