"A second function of iodine is to calm the body and relieve nervous tension. When nervous tension runs high there is irritability and difficulty in sleeping well at night, and the body is continually on a combat basis, organized for fight and flight. All these points stress a body's need for iodine to lessen nervous tension, relax the body and enable it to organize for peace and quiet, by the building and storing of body reserves against time of need. I have learned through Vermont folk medicine that it is possible to repeatedly change an irritable, impatient, and restless child under ten years of age into a calm, patient individual within two hours' time by giving one drop of Lugol's solution of iodine by mouth in a vegetable or fruit juice or in a glass of water made acid in reaction by adding a teaspoonful of apple cider vinegar. I have repeatedly prescribed this in order to make it possible for a mother of a racehorse-type little boy or girl to be able to live comfortably with the child. I have never seen it fail to calm down a nervous child." Dr D C Jarvis from Folk Medicine_
Jarvis wrote about the usefulness of iodine in shifting the gears of flight or fight to a more relaxed state and even using it to help children settle down. He understood the ADHD sydrome a long time ago.
