Part of the wart treatment protocol at Prairie Path Foot and Ankle Clinic involves applying a medication daily at home.  In order for the medication to treat the wart, it is important to remove the layer of thickened skin that forms on the bottom of the foot. The best way to do this is with pumi stone, which we have here in our office.  It works the best when it is used after a shower or after soaking your feet in order to remove the softened skin.  That way, the medication can get to where it needs to go - exactly on the wart itself.
