Blue iodine is a combination of iodine with starch. Everyone knows that starch turns blue in the presence of iodine. This is how food is checked.
The combination of iodine with starch was used in the 40s of the last century for dysentery.
Now iodine in such quantities do not take inside, but the idea of starch with iodine was picked up by the Swedes. In the early 1980s, they made the local antiseptic Cadexomer iodine. This is also starch, but very cleverly chemically altered.
If such a thing is applied to a wound, the starch draws in excess moisture and debris from the surface of the wound, and iodine is gradually released into the wound.
The remedy was named Yodosorb. It turned out to be so effective that it still hasn't lost its relevance.
Antibiotic-resistant microbes were powerless over iodine, and the dosage form of Yodosorb itself very gently interacted with the wound surface.
In terms of its gentle effect on the wound, the agent even gives odds to an aqueous solution of chlorhexidine. Iodosorb does not burn the wound and does not slow down healing.
And our blue iodine has remained an important part of history. It contains too much iodine. Such funds are now not taken orally.
In general, iodine can be in a physiological amount, which is justified by the needs of the thyroid gland. And iodine is also available in pharmacological quantities.
Well, that is, if a cardiologist has prescribed you, for example, Cordaron, then one of his tablets will contain an annual rate of iodine. This is an overkill to put up with in order to control a dangerous heart rhythm disorder.
Remember that iodine visible to the naked eye cannot be ingested. The endocrinologist will prescribe you only a microscopic invisible amount. Ask your doctor about it.
