Sour Sop
Sour sop juice is sweet stuff and I never seen a clean source---only none frozen, on the shelf with enough acids added that it never spoils....
some say the leaves cures cancers better than drugs---but many things fit that category.
If you want to create a market---just say the leaf, root, fruit, nut, etc. cures cancers and surely some will try it...
Just like when they could not sale bananas until they paid a white coat to say it has potassium---but failed to say you need to eat 1,000 bananas per day..
"IF" a person believes, enough to "convince" the subconscious mind---anything can cure cancer! Nick Named POW WOW or doctors called it---The God Cure! The power of the Subconscious Mind!
