How are common warts treated?
Warts are normally noncontagious skin growths caused by viruses. Different warts respond to different treatments. Some go away on their own. Salicylic acid products (in the form of drops, gels, pads and bandages) can help self-treatment of many warts by dissolving the keratin protein that makes up the wart and the dead skin above it. Others can be removed via liquid nitrogen freezing or electrical stimulation. CO2 lasers may be used to remove warts. The is a particularly effective method but requires local or general anesthesia.
