{182} In addition to the several remedies that have been mentioned as applicable to the treatment of the different varieties of acute and subacute bronchitis, there are many others that have been found more or less beneficial in the treatment of chronic cases. Among the more important of these are the iodide of potassium and sodium, the grindelia robusta, eucalyptus globulus, oenothera biennis, cimicifuga racemosa, asclepias tuberosa, balsams copaiba and tolu, gum benzoin, turpentine, cod-liver oil, and the hypophosphites of sodium, calcium, and iron; and a still larger number that have been used for inhalation. As a general rule, when the cough is harsh and the expectoration scanty, with the predominance of dry râles, such remedies as the muriate and iodide of ammonium and the iodides of potassium and sodium, given in conjunction with small doses of antimony and some mild anodyne, will produce the best effects. On the other hand, if the expectoration is abundant and of a muco-purulent character, the balsamic and terebinthinate remedies, given in connection with such tonics as the lacto-phosphate of calcium, phosphate of iron, sulphate of quinia and strychnia with codia, hyoscyamia, or lupulin, at night to procure rest, will afford the greatest relief. In some of these cases I have obtained very good effects from a combination of two parts of the syrup of iodide of calcium with one of the fluid extract of hops, given in doses of 4 cubic centimeters (fluidrachm j) each morning, noon, tea-time, and bedtime. When chronic bronchitis is complicated with pharyngitis and laryngo-tracheitis, much palliative influence may be obtained by judiciously-directed inhalations, either in the form of vapor or atomization. But when the disease is limited to the bronchi alone, inhalations have much less influence over its progress or in relieving the more distressing symptoms. And unless the nature of the material used is judiciously selected with reference to the particular stage and grade of the disease, the inhalations will be more likely to do harm than good. There are two conditions of the bronchi met with in different cases of chronic bronchial inflammation to which local applications can be made in the form of vapor with much benefit. The first is indicated by an abundant purulent or muco-purulent expectoration, sometimes fetid and at other times not. For such the full deep inhalation of aqueous vapor impregnated with some antiseptic and anodyne will be of great service. One of the best combinations that can be used for this purpose is that of carbolic acid with camphorated tincture of opium in the proportion of 2 grams of the former (gr. xxx) to 90 cubic centimeters (fluidounce iij) of the latter; 4 cubic centimeters (fluidrachm j) of this mixture may be put into 250 cubic centimeters (fluidounce viij) of hot water in an inhaling-bottle and the vapor inhaled freely, five minutes at a time, two or three times each day.
