These are products that have been researched and approved by the FDA. There are many, many types of warts. I have written more than 100,000 words on this topic, many of which are free.
Warts are tiny skin lesions that are often found on the body, sometimes called bumps. They can be small and non-invasive, or they may be larger, more painful, and have a more visible appearance. Warts can be red, white, brown, or purple. The type of warts and size may vary, but there are many types of warts. There are two main types of warts; granulomatous warts and cutaneous warts.
Granulomatous warts are usually red or black. They can be raised, or can be flat. In many cases, the granulomas have a characteristic pattern. These are commonly called "beads." There are different types of granulomas that can cause warts. Sometimes these granulomas are small and hard, and can be removed easily by a scalpel. Other granulomas are larger, and may be difficult to remove. Sometimes, these granulomas can be treated with radiation therapy. Some granulomas are resistant to treatment. Some of these granulomas may not grow any further, and will never appear on an index finger.
