I just read that thousands of people have had success treating nail fungus, athlete's foot, ringworm and other fungal problems using cornmeal. Some physicans speculate that the microorganisms in corn meal, activated by warm water, literally eat the microscopic fungi.
Put one inch of cornmeal, yellow or white, in a pan, and add just enough warm, not hot, water to cover it. Let this sit for 30 minutes. Then add enough warm water to cover up your feet. Soak for at least one hour once per week until the fungus is gone. For other fungal problems that require soaking in a bath, add two cups of cornmeal to the water.
