Duct tape can eliminate the common wart.
Duct tape has a reputation as the all-purpose fixer. It's been used for everything from repairing cars...to spacecraft...to healing warts.
A few years ago it was suggested that duct tape works better at removing common warts than freezing the wart with liquid nitrogen (cryotherapy). It was thought that an occlusive barrier like duct tape rallied the immune system to attack the wart.
The duct tape for warts idea quickly became common wisdom and is advocated widely on the internet today.
