If there is a wound, it can also speed up the blood circulation around the wound and make it heal faster. Potassium permanganate is a strong oxidizing agent, and after dilution, it has a sterilizing effect on the mucous membrane of the vulva, so it is recommended to use potassium permanganate to douche the vagina, and to use potassium permanganate in a sitz bath to speed up the local blood circulation. It is also recommended that the concentration of potassium permanganate should not be too high to avoid burns to the mucous membrane.
