Lugol's iodine is a solution of elemental iodine and potassium iodide in water named after the French physician Jean Lugol. Discovered in 1829, Lugol's iodine have been used for over 100 years as an antiseptic and first-aid supplementation in case of nuclear disaster.

Latest research on Iodine gives a better understanding of its extrathyroidal functions. Iodine plays a tremendous role in the proper functioning of several organs such as the brain, the prostate, skin, breasts and ovaries. Iodine is anti-septic and anti-viral. Every 17 minutes, all the blood in the body passes through the thyroid gland. Because the cells that make up this gland have an affinity for iodine, each cycle of blood passing through the gland is subjected to iodine secretions, killing germs and viruses. In the 2000's, Dr. David Brownstein highlighted the threat of fluoride toxicity and its chemical interaction against iodine.
