Salicylic acid. This is the main ingredient in aspirin, and it should usually be your first choice. According to one study, salicylic acid is the only topical treatment (treatment applied directly to the skin) that clearly outperforms a placebo. (The study, in the August 2011 issue of the British Journal of Dermatology, combined and reanalyzed data from a number of previous studies.) Salicylic acid costs little, has minimal side effects, and comes in various over-the-counter preparations, including liquids, gels, and patches. Concentrations range from 17% to 40% (stronger concentrations should be used only for warts on thicker skin). To treat a wart, soak it for 10 to 15 minutes (you can do this in the shower or bath), file away the dead warty skin with an emery board or pumice stone, and apply the salicylic acid. Do this once or twice a day for 12 weeks. Warts in thick skin, like the bottom of the foot, may respond best to a patch that stays in place for several days. Continuing treatment for a week or two after the wart goes away may help prevent recurrence
