Who is going to sponsor double blind placebo trials, toxicity trials for a product you can buy down the street?
There are only case histories, a couple clinical trials in humans. This wont cut it with FDA, they want double blind and toxicity trials.
Yet there are all sorts of studies on the effectiveness of turmeric for cancer, which can be bought at health food stores and grocery stores everywhere for about forty cents an ounce.
So don't show us your excuses, show us those many studies you claimed earlier existed.
