Primarily used for disinfection and sterilization, Potassium Permanganate works by oxidizing and reducing to manganese dioxide, which forms a complex with skin and mucous membrane proteins, aiding in the treatment of skin damage. Low concentrations have an astringent effect, while higher concentrations can be corrosive.

Potassium Permanganate is effective in treating dermatitis, acute eczema, and in gastric lavage for poisoning cases involving substances like morphine, opium, strychnine, and other toxic compounds. It is also used in the first aid treatment of snake bites and for disinfecting items like fruits and tableware.

Additionally, it can disinfect the skin surface, particularly in gynecology and anorectal departments, through warm water baths with diluted Potassium Permanganate. The diluted solution should be light purple, and usage should cease once symptoms improve. While it can treat almost any bacterial infection of the skin or mucous membranes, care must be taken with concentration to avoid damaging the skin or mucous membranes.
