As the name implies, the surface of the tongue gives the impression of a map; or the tongue may be described as being figured--some parts denuded of epithelium and other parts coated. This condition is accompanied by itching, and sometimes a burning sensation.

According to the best writers, the etiology is not known. In my practice I have found that this state of the tongue is always accompanied by obstinate constipation, with the usual toxin poisoning characteristic of putrefaction in the large intestine.

Treatment

Correct the condition of the alimentary canal by overcoming constipation and having the patient live on fruit for a week or two. If the patient is thin, about one week without food, except fruit, is enough. The prunes and fresh fruit should be taken for breakfast; uncooked apples for lunch, and oranges and figs for the evening meal. No water or other fluid is to be drunk until the bowels are normal. If the bowels are obstinate, an enema may be taken in the evening.

The second week, fruit may be given twice a day, and then a dinner of meat, cooked, non-starchy vegetables, and a salad. This diet should be kept up until the tongue is normal.
