Query: Do not buy

I bought this product because my son had a ringworm in his head and I didn't want him to take the pills that they wanted to prescribe to him. I bought this product and it did not work. I tried some other holistic approaches e.g. lemon juice, potato slice, etc. those did not work. The only product that got rid of his ring worm - again in his head was Lamisil AT. Lamisil AT got rid of his ringworm in his head (and he gave it to me on my arm) in 1 week. I massaged the cream over the affected area twice a day for 1 week and it was gone. Lamisil AT is an antifungal cream that gets rid of jock itch and ringworm and it can be purchased over the counter.
