Dissolve one teaspoonful in half a pint of water, which will keep for several days. For bronchial trouble or bleeding at the lungs, gargle the throat often; but for general cleanliness, gargle a little every morning; for catarrh, not only gargle but snuff some up the nose. =Hair.=--To prevent hair from falling out, headache, neuralgia, brain fever, etc., the hair should be worn comparatively short by both sexes, washed and dried every day. To preserve the hair this is a good recipe: Take a teaspoonful of dried sage; boil it in a quart of water for twenty minutes. Strain it off and add a piece of borax the size of an English walnut; pulverize the borax. Put the sage tea, when cold, into a quart bottle; add the borax; shake well together and put in a cool place. Brush the hair thoroughly and rub and wash well on the head with the hand; then, after a good hard rubbing, brush the hair well before a fire, so that it will become perfectly dry. Never use a fine-tooth comb, as it irritates the skin, and consequently inflames the roots of the hair. =Headache.=--The causes are: "Overstudy, overwork in-doors, neglect of the bath, want of fresh air in bedrooms, nervousness, however induced; want of abundant skin-exciting exercise, the excitement inseparable from a fashionable life, neglect of the ordinary rules that conduce to health, overindulgence in food, especially of a stimulating character, weakness or debility of body, however produced (this can only be remedied by proper nutriment), work or study in-doors, carried on in an unnatural or cramped position of the body. Literary men and women ought to do most of their work at a standing desk, lying down now and then to ease the brain and heart, and permit ideas to flow. They should work out-of-doors in fine weather--with their feet resting on a board, not on the earth--and under canvas in wet weather. It is surprising the good this simple advice, if followed, can effect. =Health Beverages.=--Lemons make the best beverage. They are very healthy and good, not only for allaying the thirst, but will cure a multitude of disorders. The juice of the lemon contains citric acid. Acids, as a rule, decrease the acid secretion of the body and increase the alkaline. Citric acid, which is the acid of lemons and oranges, for instance, will diminish the secretions of gastric juice, but increases very materially the secretion of saliva. The very thought of a lemon is sufficient to make the mouth water. Thirst in fevers is not always due to lack of water in the blood. It may be due in part to a lack of the secretion of the saliva. When the mouth is parched and dry, the acid will increase the saliva. When acid is given for the relief of dyspepsia it should be taken before eating. Lemon juice drank before meals will be found very advantageous as a preventive of heart-burn.
