Soursop Leaves (Air-Dried). Organically Sourced, hand-picked and naturally dried. Use these for Soursop Tea. A True Plant Medicine Soursop, also known as Graviola, is the fruit of the Annona Muricata Tree. I have helped picked the leaves myself and below you'll see a photo of our packet in a Soursop Tree. My point is the leaves and whole process is 100% Natrual and the leaves are Authentic and Potent. Any Soursop / Graviola Tea you see will be broken up the leaves as we think this loses something. The break itself means structural damage. Choose Soursop Leaves in their most untouched form here.
