Fungus that develops on toes can be killed by hydrogen peroxide. The concentration of hydrogen peroxide should be 3%. Soak your feet for 15-20 minutes in a tub of warm water with 3% hydrogen peroxide. You should never put bleach on your skin or eat it, but peroxide is quite safe. It is used in medicine and as a cleaning agent. It is also used to remove stains from clothes and teeth. Not only does peroxide kill fungus, but also burns hair and leaves nails stronger than ever before. If you are looking for an all-natural way to get rid of toe nail fungus, then peroxide is the solution. This natural remedy has been used for hundreds of years and is very effective at killing fungus. Peroxide is available at any drug store and only costs a few dollars for a large bottle. Bleaching your hair with peroxide is not recommended because it can cause damage to your hair follicles. However, peroxide can be used as a disinfectant for your hair before you go natural. If you want to go completely natural, look into using apple cider vinegar as well.
