The body is comprised of sixteen elements: oxygen, -*- carbon, hydrogen, calcium, nitrogen, phosphorus, chlorine, sulphur, fluorine, potassium, sodium, magnesium, iron, silicon, manganese, and iodine.

These elements are a vital necessity, in order that the body may be able to perform its physiological functions of digestion and assimilation, secretion of the glands, elimination of the poisons from the blood stream and the waste matter from the system.

Therefore, in order to keep the body in a state of health and immune from disease, the blood must contain these elements in balanced proportions, inasmuch as through the blood they are conveyed to all parts of the body to perform their particular function.
