In het boek ‘Folk Medicine’ schrijft DC Jarvis het volgende:
When used to maintain the iodine content of the body the dose is small and is taken only on certain days of the week. When the mineral content of the body is analyzed, only a trace of iodine is found. Ten drops of iodine represent more iodine than is found in the entire body. For this reason, the dose of Lugol’s solution of iodine is one or two drops (In this article Dr. Jarvis is speaking about Lugol’s Solution 5%. When using Lugol’s Solution 2% use 2-3 single drops to get the equivalent), depending on your body weight. If you weigh 150 pounds or less, for example, your dose to maintain the normal iodine content of the body is one drop, taken at one meal on Tuesday and Friday of each week. If you weigh more than 150 pounds, the dose should be two drops instead of one. It is useful to remember that the human body works on the minimum of anything it needs. If there should be a rise in sickness in the area where you live, it would be well to take the Lugol’s solution three times a week instead of two, on Monday, Wednesday, and Friday, for the purpose of storing up reserve.
