Iodine is necessary for the thyroid gland's proper performance of its work. All the blood in the body passes through the thyroid gland every 17 minutes. Because the cells making up this gland have an affinity for iodine, during this 17-minute passage the gland's secretion of iodine kills weak germs that may have gained entry into the blood through an injury to the skin, the lining of nose or throat, or through absorption of food from the digestive tract. Strong, virulent germs are rendered weaker during their passage through the thyroid gland. With each 17 minutes that rolls around they are made still weaker until finally they are killed if the gland has its normal supply of iodine. If it does not, it cannot kill harmful germs circulating in the blood as Nature intended it should. "In relation to supplemental use of iodine, my studies of certain dairy herds has revealed interesting evidences of the relationship between host and micro-organisms, viruses, insects, and other parasites.....My object was to rout these cattle grubs by means of the apple cider vinegar and iodine, combination; this would demonstrate, to me at least, what the combination would do in the way of making the body as a host unsuitable soil for the development and continuing existence of microorganisms, viruses, insects, and other parasites."
