About This Condition
Turn up the heat
Apply a heating pad set to 122°F (50°C) for 30 seconds at a time, one to four times, to regress common warts and prevent regrowth
If you have warts of any kind, avoid scratching them; if you have genital warts, limit sexual contact with others and see a healthcare professional
Warts are common abnormal skin growths caused by one of many types of human papilloma virus, which infects the outer layer of skin.
Common warts (verruca vulgaris) can appear on any part of the body but are more common on the fingers, hands, and arms. They are most common in people 30 years old or younger, but can occur at any age and are almost universal in the population. Other types of warts also exist, including flat warts, genital warts, laryngeal papillomas, and others.
Appearance and size of warts depend on the location and the amount of irritation and trauma. Common warts are sharply demarcated, rough-surfaced, round or irregular in shape, firm, and either light gray, yellow, brown, or gray-black in color. They are small nodules ranging in size from 2–10 mm in diameter. Plantar warts (on the bottoms of the feet) are flattened and may be exquisitely tender. Flat warts, more common in children and young adults, are smooth, flat-topped yellow-brown elevations, most often seen on the face and along scratch marks. Genital warts (also called condyloma acuminata or venereal warts) are soft, moist, small pink or gray polyps that enlarge and are usually found in clusters on the anus and the warmer, moister areas of the female and male genitalia. Genital warts caused by HPV are considered a major cause of Reference cervical dysplasia and cervical cancer. All warts are contagious.
Healthy Lifestyle Tips
Warts can be spread by contact, and the transmission can occur between two people as well as between different parts of the body of the same person. To prevent the spread of the virus, warts should not be scratched. Genital warts are spread by sexual contact.
A study of Reference HIV-infected and HIV-negative women found that current smokers were over five times more likely to develop genital warts than nonsmokers.1
Distant healing is a conscious, dedicated act of mental activity that attempts to benefit another person’s physical or emotional well-being at a distance. A controlled study found that distant healing by an experienced healer for six weeks had no effect on the number or size of warts.2
A controlled study found that the application of 122ºF heat from a heat pad for 30 seconds led to regression in 25 warts.3 After 15 weeks, none of the regressed warts had regrown.
Reference Hypnosis is a widely recognized treatment for warts. One controlled trial found that twice-weekly hypnosis sessions resulted in greater wart disappearance than did medication, placebo, or no treatment after six weeks of therapy.4
The right diet is the key to managing many diseases and to improving general quality of life. For this condition, scientific research has found benefit in the following healthy eating tips.
|Cut back on alcohol||
A preliminary study reported that drinking two to four alcoholic drinks per week nearly doubled the risk of developing genital warts.
A preliminary study reported that the weekly consumption of two to four alcoholic drinks nearly doubled the risk of developing genital warts.5 Those who consumed more than five alcoholic drinks had a more than doubled risk of developing genital warts. A case report of a 19-year-old with a urinary-tract wart found that abstinence from a high intake of pork led to a regression of the wart.6
What Are "Star" Ratings?
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Rub cut clove onto area nightly and cover until morning, or apply oil-soluble extract twice per day
Studies have shown topically applied garlic to be effective at clearing common warts.
In a preliminary trial, topical application of Reference garlic cloves was used successfully to treat warts in a group of children. A clove was cut in half each night and the flat edge of the clove was rubbed onto each of the warts, carefully cleaning the surrounding areas, so as not to spread any garlic juice. The areas were covered overnight with Band-Aids or waterproof tape and were washed in the morning. In all cases, the warts cleared completely after an average of nine weeks.7 In another study, 23 people with warts applied an oil-soluble garlic extract twice a day to the warts. Complete recovery was seen in every case after one to two weeks. A water-soluble garlic extract was less effective.8 Side effects after application of the oil-soluble extract included blistering, redness, burning, and increased pigmentation of the skin around the application area, which usually disappeared completely in one to two weeks. Reference Zinc oxide ointment was applied to the surrounding normal skin in all cases in an attempt to prevent these side effects.
Take under medical supervision: 2.25 mg per 2.2 lbs (1 kg) body weight, up to 135 mg per day
In one study, supplementing with zinc, resulted in complete disappearance of warts in 87% of people treated.
In a double-blind study, supplementation with oral Reference zinc, in the form of zinc sulfate, for two months resulted in complete disappearance of warts in 87% of people treated, whereas none of those receiving a placebo improved.9 The amount of zinc used was based on body weight, with a maximum of 135 mg per day. Similar results were seen in another double-blind study.10 These large amounts of zinc should be used under the supervision of a doctor. Side effects included nausea, vomiting, and mild abdominal pain.
Refer to label instructions
Herbalists sometimes recommend the use of topically applied greater celandine in treating warts.
Herbalists have sometimes recommended the use of Reference greater celandine (Chelidonium majus) for the topical treatment of warts.11 The milky juice from the fresh plant is typically applied to the wart once daily and allowed to dry.
