Saturated salt water cannot treat flat warts.
The main component of saturated salt water is sodium chloride, which has no special effect on flat warts, so it can’t treat flat warts. Flat warts are mainly treated with physical therapy (freezing, laser, scraping, etc.), topical medication (retinoic acid ointment, 5% imiquimod ointment, fluorouracil ointment, etc.), and intradermal injections. Flat warts patients should go to the hospital, under the guidance of the doctor for standardized treatment.
