Treatment of warts is easy. They can be treated by following steps

Chemical treatment

Certain chemicals like cantharidin, salicylic acid, trtinoin and glycolic acid are commonly used and very effective.  The chemical reacts with the wart amd forms a blister kind and then gradually it erodes. It will take around 5-10 days for the wart to be peeled off from the skin. After the peeling off there may be a wound formed which can be covered by band aid or left open for healing. Sometimes there may be a scar left.
