67. CAMPHOR WATER, OR JULEP, as it is commonly called, may always be advantageously kept ready prepared for domestic use; it is made by adding two drachms of Camphor to a quart bottle of water, and setting aside for a few days. Of this the dose for an adult is about a wine-glassful. It is a good vehicle for other medicines. 68. CAMPHOR LINIMENT is formed by dissolving one ounce of Camphor in four ounces of Cocoa-nut, Sesamum, or other bland oil. It is an excellent application in _Chronic Rheumatism_, _Lumbago_, _Enlargement_ _of the Joints_, _Glandular Swellings_, _Bruises_, _Sprains_, _Muscular Pain, especially that of the loins, to which women are subject during Pregnancy and the Menstrual periods_, and other cases attended with local pain. It should be well rubbed in night and morning for 10 or 15 minutes; friction in these cases playing an important part. 69. _In Chronic Rheumatism_, in addition to its use externally, as advised in the last paragraph, it may be given internally in a dose of five grains with one grain of Opium at bedtime; it affords relief by causing copious perspiration, which should be promoted by a draught of infusion of Ginger (154) and by additional bedclothes. An excellent vapour bath for these cases may be made by substituting half an ounce of Camphor placed on a heated plate for the _chattie_ of hot water described in Section 397. Thus employed, it causes speedy and copious perspiration. Care, however, is necessary to prevent the patient inhaling the vapour, which is of comparatively little consequence when simple water is being employed. 70. _In Asthma_, Camphor in four-grain doses, with an equal quantity of Asafœtida, in the form of pill, repeated every second or third hour during a paroxysm, affords in some instances great relief. Turpentine stupes (362) to the chest should be used at the same time. Many cases of _Difficulty of Breathing_ are relieved by the same means. These pills also sometimes relieve violent _Palpitation of the Heart_. _In the Coughs of Childhood_, Camphor Liniment (68), previously warmed, well rubbed in over the chest at nights, often exercises a beneficial effect. For young children, the strength of the liniment should be reduced one half or more by the addition of some bland oil. 71. _In Rheumatic and Nervous Headaches_, a very useful application is one ounce of Camphor dissolved in a pint of Vinegar, and then diluted with one or two parts of water. Cloths saturated with it should be kept constantly to the part.
