I can suggest some things, but where the fungus is on the body has a great deal to do with what to use and how to use it. Is the fungus in the mouth? Is it in the groin area? Or is it on the feet? Or perhaps somewhere else?
Maybe you can try Jojoba oil & Tea Tree Oil, or Anti Infection Formula, or Echinacea Plus. Or two or more of these in combination. There are other things too, but you can try these first.
