Apple Cider Vinegar/Coconut oil for ringworm:
It's the only thing that made the fungus tingle, but it didn't cure it.
Drinking 2 table spoons of ACV with honey in a cup of water made the fungus look much drier.
Coconut oil rubbed directly into it made it seem less apparent, it also burnt more than any other thing that I have ever applied to it.
Also, I mixed coconut oil with borax (1:1 ratio with solidified coconut oil), the results were good but only temporary.
