Preliminary research is showing promise that garlic does work for warts.
More Info: In a study published in the International Journal of Dermatology, participants with warts and corns were treated with both fat-soluble garlic and a water-soluble garlic solution. Both applications proved effective. After applying the topical treatment twice daily, the fat-soluble garlic treatment removed warts within one to weeks, while the water-soluble garlic extract removed warts in 30-40 days.
Research Concludes Garlic May Be Effective
The National Medicines Complementary Database rates the effectiveness of alternative treatments based on available evidence. Following numerous studies, the NMCD has rated garlic as a possible treatment for high blood pressure, hardening of the arteries, colon/rectal/stomach cancer, tick bites, and fungal infections.
Inconclusive Garlic Research
Though many of these studies have shown great promise, the NMCD has concluded that more evidence is necessary before garlic can be considered an alternative therapy for diabetes, high cholesterol, breast cancer, lung cancer, common cold, corns and warts, and prostate cancer.
Garlic Used as a Topical Treatment
There is evidence supporting the effectiveness of garlic when used to treat fungal skin conditions such as ringworm, athlete's foot, and jock itch. The jury is still out as to its effectiveness against corns and warts.
