On a sidenote, after WWII, research on the forgotten art of iodine therapy in medicine was started in the USSR, and some time later in America and Europe. But the Russians used it with greater success and experience in ordinary medicine and treatment in hospitals, like in the good old times before. They had great success with that. But you see, it was the cold war, and the class enemy was impossible to be described as somebody doing something better than us, the West. The Russian successes were ignored, then defamed, and Iodine was deleted from the list of Western activities.
That iodine today is so much ignored, is for political and ideological rivalry in the cold war!
Until the time between the world wars, it was common component in every household'S medikit (not for cleanign wounds, but for swallowing it), and doctors treated a whole lot of deases by giving patients iodine - in dosages that today the WHO would get crazy over. Well, it often worked. And better than many of the new drugs used today. Doctors were pragmatic. Who healed, was right. Even if he did not fully understood why it healed.
