Vinegar and flour cannot cure warts. Warts are a viral skin disease caused by human papillomavirus infection, which can lead to the appearance of common warts, flat warts, plantar warts, filiform warts and condyloma acuminatum on the skin. Vinegar and flour are both foodstuffs, and there is no evidence at this time that vinegar and flour have a therapeutic effect on warts. There are many safe and effective treatments for warts, such as topical retinoids, imiquimod cream, and fluorouracil cream under the guidance of a doctor, as well as the use of liquid nitrogen cryotherapy, laser therapy, and photodynamic therapy to remove warts as prescribed by a doctor. It is recommended to go to the dermatology department of the regular medical institutions in a timely manner, after a clear diagnosis, follow the doctor’s instructions to standardize the treatment, do not use their own arbitrary drugs, or use folk remedies to delay the condition.
