The French physician Jean Guillaume August Lugol developed Lugol’s Iodine Solution in 1829 initially as a cure for tuberculosis. Lugol’s solution is iodine and potassium iodide combined with distilled water. It has been used as a disinfectant and various medical applications and by the 1920s became the standard preoperative treatment for patients with Graves’ disease and used as a pretreatment to thyroid surgery. Lugol’s Iodine solution is still relevant in the medical community and is still commonplace for medical and supplementation purposes.
