Soursop / Graviola Leaf Powder (Annona muricata)

Ground dried leaves of Annona muricata, called Graviola (in much of Latin America), Soursop (English), and Guanábana (in Spanish-speaking Caribbean regions). The tropical tree is native to the Caribbean and tropical Americas, where the spiky green fruit is widely eaten and the leaves have traditional medicinal use across various Latin American and Caribbean herbal traditions.

Important Safety Information

Soursop leaves contain annonaceous acetogenins, a class of compounds that are the focus of mixed research. Some studies have linked long-term high-dose consumption of Annonaceae plants (Soursop and related species) to atypical Parkinsonism in populations with high traditional consumption in the Caribbean. The risk appears related to long-term high consumption rather than occasional use. Use moderate amounts, short-term to medium-term rather than continuous long-term, and consult a healthcare provider. Not recommended for individuals with Parkinson's disease, on Parkinson's medications, during pregnancy, or for children.
