I took my son to the doc for a wart and the doc refused to freeze it off until I tried this newer method that apparently has success.   It is duct tape!!!  Our doc gave me the handout on this successful treatment.   I don’t know how or who discovered this treatment, but apparently there is some chemical reaction and the wart is killed from the inside out!!!  We’ve used it twice and it worked wonderfully!!!  I cut out a tiny piece of duct tape to cover the wart and then wrap the finger in a bandaid (to keep the duct tape on).   It disappears in a couple of weeks!!
