Viral warts are caused by human papillomavirus infection. The first choice is to use a topical wart remover for treatment, which is a purely herbal preparation and also a cream, usually with 7-15 days to crust off. The effect of internal and external treatment with interferon as well as herbal tonics is not clear at present, and can be used as an adjunctive treatment. Local application of diphenylcyclopropenone can also be used for immunotherapy. The actual fact is that you should avoid eating spicy and other irritating hair products, such as chili, seafood, tobacco and alcohol, beef and mutton, carp, onions, garlic, leeks, bamboo shoots and so on. Eat more fresh fruits, vegetables, eggs and milk.
