Where actual stones are formed, or a tendency to their formation exists, all water drunk should be distilled, or boiled rain water. Where stones are present the heat may be applied to the back, but no cold in front. The soft water tends to dissolve the stones, the heat assists in their expulsion from the body. Diet same as in gout (see).

Guaiacum.—This drug is a West Indian gum, and is one of those remedies we are glad to say will do no harm, while in rheumatism and gout it is most beneficial. A teaspoonful of the tincture in a cup of hot water, or one or two of the tabloids now so easily had, may be taken three times a day.

Hæmorrhage.—See Bleeding; Wounds.

Hair Coming off.—There are many forms of this disfiguring trouble, both in the case of young and old persons. It is chiefly due to a wrong state of the skin of the head, which is best treated with careful rubbing with vinegar or weak acetic acid, and finishing with good olive oil. The acid must not be used too strong—not stronger than ordinary vinegar. This may be done every evening, and should be rubbed on for fifteen minutes, till a comfortable feeling is aroused. Dry the head, and then rub on olive oil for five minutes. The vinegar should rather be dabbed than rubbed on. Wash all over in the morning with M'Clinton's soap. Or this treatment may be applied every other night, and on alternate nights the head may be packed up with lather (see Head, Soaping). This treatment is quite safe, and will usually effect a cure, which is more than can be said of the expensive hair washes so much advertised. Many of these are most dangerous. As far as possible go with the head uncovered, and brush the hair frequently. Brushing stimulates the grease glands, and causes the hair to become glossy. Probably the reason men lose their hair so much more than women is that the brushing and combing the latter must give it stimulates the hair roots. Massaging the skin of the scalp with the fingers night and morning will greatly promote growth of the hair. See Head, Massaging.

Hands, Clammy.—Rub the hands and arms well twice a day with cayenne lotion (see).

Hands, Cold.—Much more than is readily believed depends on the state of the hands and feet. We are already familiar with the subject of coldness in the feet, but we meet with cases in which the coldness of the hands is as striking. It is not readily thought that cold hands have anything to do with such illness, for instance, as that of bad action in the stomach. There are cases in which a very great deal can be done to relieve a congested state of the vessels of the stomach, and even a similar state of the lungs, by only bathing the hands in hot water and then rubbing them with hot oil till they have been thoroughly heated and reddened, as they are when effectually warmed. Half-an-hour's bathing of hands in water just a little above blood heat produces a wonderful effect on an invalid when there is too great weakness to stand longer treatment. This is well known to be true of half-an-hour's good feet bathing. In some cases bathing both of hands and feet is much needed. The overburdened heart finds it a vast benefit when by such a bathing the blood is allowed to flow easily through the vessels of the feet and hands.

Hands, Dry and Hard.—Pack the hands in soap lather (see) mixed with a little fine olive oil. The soap must be finely lathered with a brush, not melted. Pure soft water, never too hot nor too cold, should be used, and the hands thoroughly dried after washing. See Chapped Hands.

Hay Fever.—A most effective preventive and cure for this is the inhaling through the nostrils the vapour of strong acetic acid. The acid may be on a sponge enclosed in a smelling bottle, and its vapour may be freely inhaled. Sponge all over each night with hot acid and water. The head also may be wet with pretty strong acid, and tied up so as to keep in the vapour. Do not, however, use a waterproof covering.

Headache.—There is a vast variety of ailments associated with what is called headache. In itself, it is just more or less pain in the head. When there is such pain, it means that some of the nerves in the head are in a wrong state, probably in nearly all cases a state of more or less pressure. This pressure hinders the free flow of vital action along the nerve, and this hindrance we feel as pain. To remove the pressure is, then, to relieve the pain. Pressure from overwork often causes headache on week-days, which goes off on Sabbath. The rest here removes the pressure, and so the pain. The pressure results from a failure of energy in some part of the head, slight swelling then taking place. To increase the energy is to effect a cure. This may be done by first, at bedtime, soaping the back with warm water and soap (see). Then dry, and rub firmly yet gently with hot olive oil, until the whole back glows with warmth. This may take perhaps fifteen minutes. Then give three minutes of warm water pouring over the back. Dry again, and oil with hot oil, and put the patient to bed. Avoid much tea. Avoid altogether tobacco and alcoholic liquors, which of themselves will often cause the trouble. This treatment applies to all that numerous class of headaches which arise from overwork and fag. A cure may often be had by its means, without taking a holiday. But where this can be done, it is well to take it.
