Why is iodine put on cuts?!

Why is iodine put on cuts?

My father got a long, deep cut with a broken mirror and he went to the clinic. He got 3 stitches. After a few days my father changed the bandage himself at home (I helped. He's a doc. so he knew what to do).

He put some brown stuff on the cut which he said is 'iodine'.

I was wondering why is iodine put on cuts and wounds?

Thank you!

Iodine is a halogen like chlorine, bromine, fluorine. These chemicals are very active in germ killing, but iodine is not as aggressive as the others and is more gentle. It is also a necessary nutrient for the body that most of us are deficient in due to all the fluoride being put in drinking water, in all sodas, fluoride toothpaste, etc. Most Americans are very deficient in this nutrient. Just paint a golf ball size smear on your chest of "tincture of iodine" and it should be there in 24 hours. If it disappears before that, you are deficient. The body will absorb what it needs and not if it doesn't need it.

All your organs need iodine. Only about 3% of all the iodine you ingest ends up in your endocrine system where thyroxine is produced that keeps your thyroid working normally. The rest ends up in the rest of your organs, like skin. If you are deficient, your whole body suffers.

That's why it is such a good disinfectant.

Good luck to you
