5. Mouthwash
Mouthwash that contains thymol can be used as a cure for toenail fungus. There are many companies that make this type of mouthwash. When purchasing mouthwash with the intent to use it as an antifungal you will want to make sure that it contains thymol, which is also called thyme oil.
This compound comes from thyme and can be beneficial when it comes to fighting off fungus. To use mouthwash as home remedy for your toenail fungus you will need to soak a cotton ball in the mouthwash and then apply the cotton ball directly to the affected nail as well as around the skin. Mouthwash can also be mixed with warm water and used as a soak. However, this dilutes the thymol which is the active component. This will make it less effective at killing the fungus that is causing the toenail issues.
