My son (age 6) recently developed warts on a few locations on his body. I tried treating the largest one with an over-the-counter wart removal liquid, but that only seemed to make things worse. It totally burned when I put it on his skin; he cried for nearly an hour. Now the wart is a huge mutated scab. I want to take him in to the Dr. for the traditional nitrogen freezing wart treatment, but I've had it done in the past and found it to be quite painful. I was told by a friend that you can orally take Thuja Occidentalis, which comes from a cedar tree, to treat warts. Apparently, it works quite well; but, as with everything, I'm skeptical. I've done a bit of research on the web, but I am still wondering if a natural treatment like this is safe to use for children.

Any advice?
