Boil three or four Lipton Flo-Thru Tea Bags in one quart of water for ten minutes. Add enough cold water to make a comfortable soak. Soak your feet for twenty to thirty minutes, then dry and apply food powder. Do this twice a day until odor is under control. Then continue twice a week to keep odor under control. Tannin, which can be found in tea, is a drying agent.
