The wart is also known clinically as a common wart, so named because of the hair-like black spines on its surface. The wart can be treated in a variety of ways, including topical medications such as tazarotene gel and retinoic acid cream. Topical keratolytics can also be used, such as 10% salicylic acid ointment and salicylic acid phenol paste. Topical immunomodulatory drugs, such as 5% Imiquimod cream, can also be used. You can also use topical medications that inhibit viral replication, such as recombinant human interferon alpha-2b gel, and you can also choose to use topical Chinese ointments that remove decay and create new growth, such as Wu Miao Shui Xian cream. There are also physical therapy options such as scraping, liquid nitrogen freezing, electric drying and carbon dioxide laser treatment.
