The local or temporary disorders are caused and controlled entirely by diet, usually overeating. Sometimes overingestion of some one particular food; for instance, too much acid taken in the form of berries, or citrus-fruits, will often produce an eruption or a rash within a few hours after eating. [Sidenote: Eruptions augmented by autointoxication] That form of pimples or eruptions caused by overeating is usually augmented by constipation or by some form of intestinal congestion, which has been given the impressive title of autointoxication. Autointoxication is a broad word that seems to have been invented, not for the purpose of explaining, but for the purpose of evading the necessity of explaining. The meaning of this word (self-poisoning) has been narrowed down by the profession to describe the above conditions, but in reality it should be applied to all forms of self-poisoning by overeating; eating the wrong combinations of food; the use of all stimulants and narcotics, such as tobacco, tea, coffee, liquor and wines of all kinds. In fact, self-poisoning from the last-named sources is as common as from errors in eating, and much more difficult to control. Nearly all dis-eases are traceable directly to unexcreted poisons which the body has been unable to throw off. These poisons are from two sources: 1 The natural poisons or gases that accumulate in the body under normal conditions, which, if prevented in any manner from passing off, will cause some kind of disorder which would come under the head of autointoxication. 2 The poisons that accumulate under abnormal conditions, such as hitherto described, and which are very often made manifest by eruptions of the skin. [Sidenote: Constitutional disorders] That form of skin dis-ease known as eczema has baffled the medical world for many centuries. It has hitherto been treated locally by the most skilled and learned specialists, in the belief that it was of bacteriological origin, but modern experiments in the field of food chemistry have demonstrated the fact that it can be cured by scientific feeding, therefore it is only fair to assume that its origin or primary cause is due to some form of self-poisoning, caused by errors in eating and faulty metabolism. DIS-EASES OF THE SKIN--THE TREATMENT If a rash should appear on the skin after eating acid fruit or berries, one would naturally know the remedy; namely, omit acids, limit the quantity of food at the next meal, drink copiously of pure water and breathe an abundance of fresh air. The same general remedy should be observed in all cases. [Sidenote: Preliminary treatment for dis-eases of the skin]
