Native to Colombia the guanábana can grow to the size of a watermelon and is normally used for juice. For many exotic fruits there are curing and medicinal clams made that have not been supported by science. The indigenous people of Colombia have been using many of the endemic fruits and tree parts for a variety of illnesses yet they don´t live longer than anyone else. Elements of this plant have shown anti-cancerous effects. Photographed in Barranquilla.
