Warts are small growths caused by the human papilloma viruses (HPV) of which there are at least 60 different known strains. They can appear singly or in clusters and are most common on the hands, fingers, elbows, forearms, knees, face and the skin around the nails. Usually, they occur on skin that is continually exposed to friction, trauma or abrasion. This is a highly contagious virus and warts can easily spread to other parts of the body where there is a break in the skin. We recommend the use of lysine, a powerful amino acid that inhibits viral replication together with an appropriate topical product.
