Warts are caused by a papilloma virus, which affects the immune system and results in the occurrence of skin growths. Typically, warts go away without treatment, as soon as the immune system builds up immunity to the virus; however, if you would like to speed up the recovery or you are bothered by the appearance of the warts, there are some chemical solutions that can be applied to get rid of warts.
Salicylic acid is a chemical that can burn the warts. Over the counter salicylic acid may be found in aspirin, but for the warts treatment, a higher concentration acid is needed and this can only be obtained through prescription from a dermatologist. Topical creams such as Durasal can be effective in removing warts.
Dinitrochlorobenezene or DNCB
DNCG is a chemical that can be used topically to remove warts. The topical cream that contains DNCG is effective in 80% of cases when applied on fresh warts, fighting off the viruses that cause the warts. DNCG is more powerful than salicylic acid and can be obtained only through prescription.
Cantharidin is a chemical that can be obtained from beetles as well, but may also be produced synthetically. If applied on the warts, the solution will cause the swelling of the warts and these should soon turn black and fall off. The chemical is often mixed with podophyllin.
Bleomycin is a chemical that may be used for warts and will kill the tissues that are affected by warts. However, this compound is rarely used, due to its high price.
