Can You Use Ice and Salt Cure a Wart?
Removing warts by freezing is a well-known method, but liquid nitrogen is used for freezing them. Ice does not cause the tissues in the warts to freeze and become dead, as the temperature is not sufficiently low. With liquid nitrogen, the temperature can go down to negative 320 degrees Fahrenheit.
Warts are caused by a virus, and although there are numerous home remedies, the removal of warts is best left to professionals. Aerosol sprays are available that freeze the warts by lowering their temperature to negative 70 degrees Fahrenheit. This method of curing or removing warts is called cryotherapy. Laser treatment and chemical peeling are other methods used for curing warts.
