I decided to give the duct tape thing a try for plantar warts, not having much success with medications or freeze off methods. I thought I’ll just start using the duct tape while I’m waiting to be able to get some of the essential oils that are recommended. But within the first day, there was noticeable improvement, and within days, the warts were gone with only holes left. I’m keeping the duct tape on until the holes and calluses are gone too, just to be sure, but I’m really impressed. I wonder why it works.
