If you use a peeled clove of raw garlic and cut it in half, and then rub the moist cross section on the open wound or the itchy part between the toes, you will feel extreme burning and pain. If you apply the moist cross section on the itchy skin of the crotch, your crotch will burn like hell.
Raw garlic can be applied to gangrene that has an open wound and even pus and blisters if one can tolerate the stinging and burning and extreme pain.
Raw garlic is a natural antiseptic. It will kill the bacteria in the intestines and in fecal matter. It will also dehydrate fecal matter and tighten the prostate.
