Fundamentally, potassium permanganate is not a drug for hemorrhoids and has no special effect on the treatment of hemorrhoids, it is only used for local cleaning and disinfection. For example, after anal or perianal surgery, you can add a little potassium permanganate when you go home for cleaning to disinfect and sterilize. But there is no specific effect of using potassium permanganate solution to treat hemorrhoids. If there is edema in the hemorrhoid, or post-operative edema, using warm water with a little potassium permanganate can promote blood circulation and play a physiotherapy role.
