Vomiting.--In many cases of severe illness, the stomach rejects all food, and the patient comes near to dying of simple starvation. On the slightest nourishment being taken, retching and vomiting ensue, the stomach being irritated beyond all possibility of its doing its work. This occurs in cancer and ulcers in the stomach, as well as in various disorders and stomach inflammations. "Rum and milk," "claret," and all alcoholic drinks are most injurious in such cases, and should _never_ be given. To soothe the irritation, the stomach should be soaped in the same manner as recommended in Head, Soaping the (_see also_ Lather). We have seen, even in very bad cases of cancer, such an application cause all retching to cease almost at once. When this has been carefully and gently done, give exceedingly small quantities at first, of infants' food, or milk and boiling water. To give any "rich" things is a fatal mistake. Oatmeal jelly may be given also, but beginning with a teaspoonful at a time (_see_ Assimilation; Digestion; Nourishment). By gradually working up the amount, a patient's life may be saved on this simple oatmeal jelly which would be lost if richer things were given. Often the stomach rejects food simply because it is surfeited. It may be that the liver is out of order, having had too much to do. Abstinence from food for a day or two, and then reducing the meals to two, taken, say, between 10 and 11, and 5 and 6 o'clock, will greatly help. Masticate the food till it is reduced to a liquid, in this state the quantity required will be wonderfully reduced and the work of the stomach lessened. Water, Hot.--The frequent prescription in these papers of hot water, to be taken often in small quantities, makes it of importance that some explanation of its action should be given.
