Acidity of the Stomach.--Often caused by unwholesome food, bad or deficient teeth, or by too rapid eating. Where these causes exist, they should be first removed. Eat slowly, and not too much at a time, and see that only _well-cooked_, easily digested food be taken. Pastry, sweets and carbonaceous foods in general should not be taken alone at the same meal, they should always accompany some form of proteid food. If, however, pain in stomach is found after meal it will be found that milk can be substituted with comfort. (_See_ Diet). (_See_ Food in Health). If this does not cure, do not take soda as a remedy. Although soda neutralises the sourness, it produces other effects, and tends to cause disease of the stomach. A wineglassful of hot water, with a teaspoonful of white vinegar in it, is the best cure. Although this is itself acid, it acts so as to remove the _cause_ of the sourness in the stomach, and is most beneficial otherwise. It is still better to take a tablespoonful of this hot water and vinegar every five minutes for an hour daily before dinner. Instead of the vinegar, a slice of lemon may be put in the hot water. This will act more efficiently in some cases. In other cases a teaspoonful of Glauber's Salts, taken in a _large_ tumblerful of hot water, half-an-hour before breakfast, for a few weeks, will relieve almost entirely. Readers must note not to use _both_ the salts and vinegar drink at once. They are intended to cure different sorts of stomach acidity, caused differently. Look also well to the warming of COLD FEET (_see_), and see that the whole skin be cleansed daily with soap lather (_see_ Lather and Soap) and stimulated with olive-oil rubbing. Aconite.--Often in cases where our treatment fails to cure, the failure is due to the patient taking aconite as an allopathic remedy. Used homoeopathically, it may be harmless, but if taken in considerable doses, even once a month, it prevents all cure. It gives relief in heart palpitation, and in case of extreme sensibility, but its other poisonous effects far outweigh the temporary benefits. A gentle, kindly soaping with soap lather (_see_ Lather and Soap) over all the body will relieve extreme sensibility far better than aconite, and can be frequently repeated without injury. Aconite must be avoided if our treatment is to be effective.
