There are two distinct kinds of skin dis-eases, namely—
1 Local
2 Constitutional
The local is that which manifests itself in the form of pimples or eruptions which come and go, and are of only a few days' duration. The second, or constitutional kind, is that which manifests itself by a permanent irritation or inflammation, which is classified as eczema, psoriasis, etc.
DIS-EASES OF THE SKIN—THE CAUSE
Local disorders
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.
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.
