There are many wives tales about how to treat a wart at home – from taping pineapple to the wart to putting on duct tape.  While the jury is still out on these types of treatments, you can purchase a variety of over-the-counter treatments for warts these days.  Compound W is one of the most commonly used wart treatments.  It is a salicylic acid that is applied to the wart to damage the skin where it lies and kill the wart.  If you do try this method, beware of where the acid spreads, as it quickly damages the healthy skin around the wart and can make it difficult to tell where you are treating the next time.  There are also over-the-counter freezing treatments, but these tend to not be effective on plantar warts, as the skin on feet is thicker and the cold typically does not penetrate far enough to reach the base of the wart.  If you try any at-home wart treatments, it is best to follow-up with a doctor if the wart doesn’t improve within a couple of weeks.
