This is only experimental work but this absolutely unexpected discovery that came out of nowhere showed that injecting the active ingredients in hot peppers, capsaicin, into the pancreas of diabetic mice helped them recover from the most devastating and troubling form of diabetes, Type 1. This is only 5% of diabetics, but the most challenging one as Type 2 diabetes is virtually 100% recoverable with natural methods f frequently described on this site(LINK).
This is all preliminary work though, but studies should be quick and there may be a product available in a few years. And here’s the GOOD NEWS, this is a natural product so the likelihood of serious side effects is very small.
