Graviola also referred to as soursop, custard apple, and guanabana, is grown in forests. Benefits associated with soursop, including soursop tea and soursop juice, may be another reason to care for trees and nature and practice being environmentally friendly. After all, sufficient forest and farm areas are needed for Graviola trees to thrive. The scientific name for the evergreen tree is Annona muricata. It's this very tree that Herbal Goodness farmers cultivate organic Graviola from.
