Warts do not have roots.
Warts grow in the outer layer of human skin only and as a result, do not have roots. They are classified based on their location and appearance: common warts; plantar warts, found on the bottom of a person's foot; flat warts, which afflict the face, neck, palm, and hand areas; and genital warts.
There are more than 60 varieties of the human papillomavirus (HPV), the infection that leads to warts. In a majority of cases, excluding genital warts, these skin growths are harmless and can disappear without need for treatment.
However, when warts recur or persist, a variety of treatment options are available. These include: freezing warts with liquid nitrogen and waiting for the growths to fall off within a week; applying cantharidin to the wart(s) area and covering with a bandage; local anesthetic scalpel slicing; deep freezing surgery, also known as cryosurgery; and laser surgery.
In terms of home remedies, the most common over-the-counter medication used to treat warts is actually the same ingredient found in headache aspiring pills: salicylic acid. Marketed under such brand names as Dr. Scholl's Clear Away, Tinamed, and Compound W, the liquid substance is meant to be applied directly to the wart(s), nightly, for up to 12 weeks. These products gradually peel away the wart.
It sounds almost like a practical joke, but in 2002, a side-by-side comparison found that the application on warts (and subsequent removal) of duct tape was a more effective treatment method than freezing the growths with liquid nitrogen.
Duct tape was placed on warts for a period of six days. Once the tape was removed, the wart was then softened by the affected area being placed in warm water for a period of 20 minutes. The wart area was subsequently buffed down with an emery board or pumice stone, before a new piece of duct tape was applied for six more days. In other words, the duct tape method is not about "ripping" the wart violently from the skin.
