I have had ringworm on my back for a few years and this past winter it exploded. The topical creams from my doctor stopped working. Finally went to see my naturopath and she put me on an anti-fungal protocol for a month. And she gave me ozonated olive oil to use topically. I use that twice a day and the marks have almost completely disappeared in 10 days. It smells strong (kind of rancid - but it's the ozone) but it works amazingly well. This is the one I have. https://www.shaughnessypharmacy.com/products/ozonated-olive-oil

Keep it refrigerated to keep it potent. Wear an old t-shirt while sleeping so you protect your bedding. Multiple thin applications are better than one thick one.

I have tried everything for this and am blown away by the effectiveness of the ozone. I hope it helps others.
