A group of doctors compared duct tape’s effectiveness with liquid nitrogen in removing warts. After two months of wearing duct tape on a daily basis and using a pumice stone about once a week to exfoliate the dead skin, 85 percent of patients’ warts were gone, whereas freezing only removed 60 percent.
The question is whether there is something in the chemical adhesive itself, or if the occlusion (suffocation) causes the destruction of the wart. The other thinking is that the duct tape causes irritation, which stimulates our body’s immune cells to attack the wart.
Regardless of the reason for the duct tape being an effective wart remover, it is a safe and cheap way to take care of an unsightly skin issue.
