Potassium permanganate is a strong oxidizing agent with mainly antibacterial and antiseptic properties. It can be used clinically for infectious diseases of the skin, for eczema, and for relief in case of poisoning. It is often used for gastric lavage, or for disinfection of fruits and utensils. The therapeutic effect of potassium permanganate is mainly due to its strong oxidizing properties, which can be reduced to manganese dioxide, thus having a bactericidal effect. At low concentrations, potassium permanganate also has an astringent effect. When using potassium permanganate, it is important to note that the concentration varies considerably depending on the route of application or the purpose of treatment. It should be prepared to the appropriate concentration according to medical advice or the recommended preparation method in the instruction manual. Potassium permanganate is corrosive, so care should be taken when using and preparing it.
