In World War 1, the soldiers fighting in the trenches often got "trenchfoot".
We usually don't give our feet much thought, but after seeing this,....you will.
I've used Apple Cider Vinegar to kill toenail fungus. Apply enough vinegar to a one square inch bandage to soak the pad of the bandage and put the bandage over the front of the toe. The next day/night, you should notice a BIG difference.
ATTENTION DIABETES SUFFERERS: Do not do this without doctor's knowledge....vinegar is acidic.
