An Ancient Purity Essential... Iodine is found in every organ of the body and is essential for humans. Almost all of us are low on Iodine. Low Iodine levels are linked to many health problems. In 1829, a French physician named Jean Lugol originated a solution which contains 5% of elemental Iodine in a 10% solution of Potassium Iodide. It has been used steadily ever since.
