Lugol's iodine, also known as Lugol's solution, first made in 1829, is a solution of elemental iodine and potassium iodide in water, named after the French physician J.G.A. Lugol. Lugol's iodine solution is often used as an antiseptic and disinfectant, for emergency disinfection of drinking water, and as a reagent for starch detection in routine laboratory and medical tests. It has been used more rarely to replenish iodine deficiency. Lugol's Solution is Potassium Iodide and Iodine in Distilled Water. A 2% Iodine and 4% Potassium Iodide + Distilled Water is Lugol's Solution but not the "Strong Iodine Solution" which is Potassium Iodide 9.5-10.5% and Iodine in the 4.5-5.5 % range + Distilled Water. Except for dilution, the ingredients and results are the same. Lugol's Solution 2% is not a Sodium based Iodine solution; it is the genuine article in a dilute format. The Gerson therapy uses Lugol's 2%. With respect to use, simply double (more or less) the use level of the 2% if one wishes to achieve the 5% equivalent. It is not to be confused with tincture of iodine solutions, which consist of elemental iodine, and iodide salts dissolved in water and alcohol. Lugol's solution contains no alcohol. Other names for Lugol's solution are I2KI (iodine-potassium iodide); Markodine, Strong solution (Systemic); and Aqueous Iodine Solution BCP. |
