Potassium permanganate is a strong oxidizing agent with disinfecting and antiseptic effects. Therefore, it is often used clinically for cleaning and disinfecting infected wounds to make them heal as soon as possible, and also for soaking postoperative wounds to prevent concurrent infections and promote early wound healing. It is also often used to douche the vagina, anus, and treat ulcers and abscesses, etc., which are clinically effective. However, the drug is also irritating and has many contraindications, so it is recommended to use it under the guidance of a professional doctor. And potassium permanganate is clinically applied for about 5-7 days as a course of treatment, when it is given to the wound soak or sitz bath for about 15-20 minutes.
