Actually, a Zapper will do it. I used to get ringworm and pink eye a lot from our farm animals, and Colloidal Silver helped the pink eye, and the Zapper got rid of the ringworm. Very fast, and not much hassle. I would have ringworm on my collar, breast and arms and it was just annoying. Zapping got rid of it in one day. I had it come back a couple of times, but just Zapped it and it went away again. This was a long time ago (a couple of years), and the Zapper I used (and still use when I need it) was the $10 Zapperplans.com Zapper. Nothing big, but it worked!
I hope this helps! The garlic will probably work too though. :)
