I had ringworm which I tried getting rid of with tea tree oil, straight, but this just made it worse. After about 3 weeks of suffering with it and it spreading I stopped the tea tree oil and then began using organic unrefined coconut oil, the kind you eat or cook with. This was so soothing and the ringworm got better and then went away!!! I just want to get the word out. Coconut oil worked excellently for me (and I was getting desperate). I did also take some oil of oregano internally to help my immune system. If you try this and it works for you, keep spreading the word!! No need for people to suffer and itch.
