Use baking soda, cornstarch, garlic, cinnamon, lemon or vinegar to remedy foot fungus at home, advises HowStuffWorks. Eat foods such as red meats, broccoli, yogurt that contains live acidophilus, and scallions to further resist fungal infection by boosting the immune system.
Distribute baking soda into shoes to absorb moisture to prevent fungal infection, states HowStuffWorks. Mix cornstarch with one garlic clove and a little olive oil to create a paste, and place the mixture on the feet and toes for 15 to 30 minutes daily. Brown the cornstarch for better result by baking it at 325 degrees Fahrenheit until it turns a slightly brown color.
Soaking the feet in a bath of eight to 10 broken cinnamon sticks soaked in 4 cups water for 15 to 30 minutes is another foot fungus treatment recommended by HowStuffWorks. Rinse the feet with squeezed juice from a lemon mixed with 2 ounces of water to reduce the foot sweating that produces fungus. Soak the feet with 1 cup vinegar mixed in 2 quarts water for up to 30 minutes every night to combat foot fungus, or apply a mixture of 1 cup vinegar mixed with 1 cup water directly to the fungus with a cotton ball.
