I love Jagua drink ( cider? ) they make here, it's more like an infusion, they soak the fruit in a jar with water and sugar, it ferments a bit. regarding the tree, from what I have been told, it takes a long time before the tree produces fruit, over 7 years. from seed.
I noticed you mentioned diabetes, you might want to take a look at Gynostemma pentaphyllum. its a vining herb, used as a tea. I usually try and stay away from the over the top claims by people selling miracle pills, and go for scientific research instead.
