Potassium permanganate can treat itching of the vulva. Potassium permanganate treats vulvovaginal itching mainly through its strong oxidizing properties, which act as a disinfectant, antiseptic and antipruritic. Itching of the vulva may be caused by chemical irritation or irritation of vaginal secretions from vaginitis. If it is simply caused by sanitary napkins or local dampness, it can be treated with potassium permanganate in a sitz bath, usually half a basin of warm water with 2 potassium permanganate tablets in a sitz bath or washing the vulva. If it is caused by vaginitis, in addition to washing the vulva, you need to treat the vaginitis symptomatically in order to cure the vulva itching completely. Care needs to be taken when using potassium permanganate because it is strongly oxidizing and if wet hands touch the tablets directly, it may lead to oxidation burns on the hands. Also need to pay attention to the concentration of water dispensing, generally about 1:5000 is appropriate, too thick can also cause vulvar skin discomfort, and even burns may.
