Potassium permanganate is a strong oxidizing agent with disinfecting and antiseptic effects. However, the decision to use potassium permanganate in the bath should be made on a case-by-case basis, for example, if the patient has trichomoniasis, bacterial vaginosis, miscellaneous bacterial infections or poorly healed vulvar wounds, potassium permanganate can be used in the bath to improve the local symptoms and to disinfect and antiseptic effects. If the patient has Candida vaginitis, it is not recommended to use potassium permanganate baths because the vaginal environment of Candida vaginitis patients is acidic and potassium permanganate baths aggravate the acidic environment, which is more conducive to the growth of Candida and aggravates the clinical symptoms.
