Given this versatility, it wasn't so surprising when a group of doctors in Ohio reported that duct tape could get rid of warts. Their study showed that covering warts with duct tape was a lot more effective than cryotherapy, an accepted treatment that involves freezing warts with liquid nitrogen. It was just the kind of offbeat finding that launches a thousand headlines.

One of the theories about how duct tape might treat warts is that the skin underneath the tape starts to break down a little bit, stirring up a local immune response that attacks the human papillomavirus. Another possibility is that the tape "debrides and debulks" the wart, removing some of the top (and, unfortunately, the skin around the wart) whenever it's pulled off.
But before getting too wrapped up in explaining how duct tape might work, we also have to consider the possibility that it doesn't -- or at least not very well. Aside from the initial report, the research results haven't been looking so good. In 2006, for example, a Dutch group reported the results of a six-week trial that compared duct tape to those little donut-shaped pads for corns and calluses. The duct tape was only ...
