Potassium Permanganate

I ran across and purchased an old copy of the

Textbook of Materia Medica Pharmacology & Therapeutics

by Blumgarten 7th edition, 1941 reprint.

It is some interesting reading!!!

One thing that was very interesting was it's several references to Potassium Permanganate. I haven't been able to find it yet, but am looking. I did a search and found an interesting site dealing with it; http://www.fishdoc.co.uk/treatments/potassiumpermanganate.htm 

What Blumgarten had to say about it was: " Potassium Permanganate is a salt of manganese. When potassium permanganate comes in contact with oxygen substances, such as the albumins of the tissues, it combines with them and liberates oxygen, which destroys bacteria, acting as an antiseptic and disinfectant. When it has combined with the albumins, it no longer liberates oxygen and, therefore is not effectual. For the hands and wounds it is used in a 1-3 % solutions. In a gargle and for douches in 1:1000 to 1% solution. It is used occasionally in poison ivy rash. In India it is used for snake bite. The holes made by the fangs of the snake are induced by an incision and potassium permanganate crystals are packed in it.

The book goes on to say "This preparation gives off oxygen. It is often given in cases of poisoning from various drugs. For example, in morphine poisoning it is given to neutralize the morphine by the oxygen which it liberates, which then combines with the drug and makes it inactive. It is also used as an antiseptic, acting in a similar manner, the oxygen destroying the bacteria.

Thought this was interesting, as most diseases, and injuries won't heal well without oxygen saturation in the tissues.
