This disease may generally be cured at the beginning; but after it has continued long, the cure becomes very difficult. In drunkards, and very old people, a perfect cure is not to be expected. REGIMEN.——Every thing that stimulates the urinary passages, or tends to relax the habit, must be avoided. For this reason the patient should live chiefly on solid food. His thirst may be quenched with acids; as sorrel, juice of lemon, or vinegar. The mucilaginous vegetables, as rice, sago, and salop, with milk, are the most proper food. Of animal substances, shell-fish are to be preferred; as oysters, crabs, &c. The drink may be Bristol-water. When that cannot be obtained, lime-water, in which a due proportion of oak bark has been macerated, may be used. The white decoction[122], with isinglass dissolved in it, is likewise a very proper drink. The patient ought daily to take exercise, but it should be so gentle as not to fatigue him. He should lie upon a hard bed or matrass. Nothing hurts the kidneys more than lying too soft. A warm dry air, the use of the flesh-brush, and every thing that promotes perspiration, is of service. For this reason the patient ought to wear flannel next his skin. A large strengthening plaster may be applied to the back; or, what will answer better, a great part of the body may be wrapt in plaster. MEDICINE.——Gentle purges, if the patient be not too much weakened by the disease, have a good effect. They may consist of rhubarb, with cardamum seeds, or any other spiceries, infused in wine, and may be taken in such quantities as to keep the body gently open. The patient must next have recourse to astringents and corroborants. Half a drachm of powder made of equal parts of allum and the inspissated juice commonly called _Terra Japonica_, may be taken four times a-day, or oftner, if the stomach will bear it. The allum must first be melted in a crucible; afterwards they may both be pounded together. Along with every dose of this powder the patient may take a tea-cupful of the tincture of roses[123]. If the patient’s stomach cannot bear the allum in substance, whey may be made of it, and taken in the dose of a tea-cupful three or four times a-day. The allum-whey is prepared by boiling two English quarts of milk over a slow fire, with three drachms of allum, till the curd separates. Opiates are of service in this disease, even though the patient rests well. They take off spasm and irritation, and at the same time lessen the force of the circulation. Ten or twelve drops of liquid laudanum may be taken in a cup of the patient’s drink three or four times a-day.
