Fungis on Toes

I don't know if any of you out there has a terrible fungas on your toe, but I do. I would like an answer to cure this. I just heard of a new one. It is to take listerne and soak your toe in it for 15 minutes for 3 days. Then let your toe nail grow out. I hope that it works. If any one wants to try it out with me. Let me know how it works.
