Potassium permanganate can be used to clean the vulva once a night if used as daily care. If used as a treatment for vulvodynia, vaginitis or eczema, it is recommended to clean the sitz bath or clean the affected skin 2-3 times a day. Potassium permanganate is a strong oxidizing agent with bactericidal effect, which can kill various bacteria, fungi and other pathogenic microorganisms, and should be diluted before use. For gynecological daily care cleaning or postpartum vulvar lateral incision care, you can choose a lower concentration of external washing, sitz bath, wipe, etc. For acute and chronic gynecological vulvar or vaginal inflammation, the number of applications can be increased, along with vaginal plugs to enhance the therapeutic effect, and care should be taken to abstain from spicy and stimulating foods and suspend sexual intercourse. In addition, potassium permanganate can also be used as a gastric lavage for accidental morphine, opioid or organic poisoning and as a first aid treatment for snake bites under professional operation.
