Since the ringworm fungi is basically the same as athletes foot and jock itch fungi (tinea). There is a some what natural way to get rid of it. I did a post under the alternative therapies. Even thought I have normal skin it has been known to work on diabetics and others with different skin disorders. Ozonated Olive Oil contains high levels of oxygen which can kill fungi and bacteria. I am not sure if it will help someone with ichthyosis. But who knows. I do hope it helps. It did help with my ringworm several yrs ago.
Where is my wallet.
