Graviola
From Appropedia
This tree is low and is called graviola in Brazil, guanabana in Spanish and has the uninspiring name "soursop" in English. The fruit is very large and the subacid sweet white pulp is eaten out of hand or, more commonly, used to make fruit drinks, sherbets and such.
The principal interest in this plant is because of its strong anti-cancer effects. Although it is effective for a number of medical conditions, it is its anti tumor effect that is of most interest. This plant is a proven cancer remedy for cancers of all types.
Besides being a cancer remedy, graviola is a broad spectrum antimicrobial agent for both bacterial and fungal infections, is effective against internal parasites and worms, lowers high blood pressure and is used for depression, stress and nervous disorders.
