Warts are caused by viruses that infect the top layer of the skin, and herbs and homeopathic remedies can be used to treat them. Most warts do not cause any pain, but they can become sore or itchy. They can appear on most areas of the body, including the feet, hands, lips, or genitals. The types of warts include common warts, flat warts, genital warts, and plantar warts. Home remedies, including vitamins, homeopathy, and herbal remedies can safely and effectively remove warts.
