Dilute definitely dilute! I had the bright idea of using a bandaid damp with Apple Cider Vinegar undiluted overnight to cure my ringworm faster. I let it breathe at work and put one on when I got home and changed it before I went to bed. After the second night, it started burning as I put the bandaid on. I dealt with the mild irritation for about 30 minutes and it only got worse. My ringworm is now half cured scaly, itchy, dry and full of scabs due to the acv. I love Apple Cider Vinegar to death and am all for home remedies, but next time I'm using a ringworm ointment.

I have used ACV for many years, it will not "cure" the ringworm on my scalp, but it will keep it from showing activity. It is still there, I have tried violet Gentian, tea tree oil and everything else I have heard of. Now I will get a prescription and get rid of it.
