Does apple cider vinger work on warts?

Yes, it does.

While I'm still learning the science behind it, I can tell you from observation of applying Apple cider vinegar to my son's warts that it causes them to disappear. We apply the ACV directly to the war with a q-tip and then I put some on a bandaid, which I then place on the wart. I like to make sure that the wart is completely covered and no oxygen is permitted under the bandaid.

My son had a filiform wart on his chin that is almost completely gone, and we have begun treatment on the periungal wart under his thumbnail. This seems to be the most painful for him - the others seem to be rather painless. We have used this process a few times before. He seems to get them mostly on his chin/around his mouth, and on his fingers.

It is my intuition that because it's caused by a virus, that stress causes the outbreaks, so I'm working on both strengthening his immune system, as well as reducing the stress as much as I can (which is difficult, with a move to a new house/neighborhood, new school, and continued shuttling back and forth to and from his Dad's house on the weekends). Also, better hygiene with hands might be in order.
