Expectorants are medicines which modify the character of the secretions of the bronchial tubes, and promote their discharge. Most of the agents of this class are depressing in their influence and thus interfere with digestion and healthy nutrition. Their application is very limited, hence we shall dismiss them without further consideration.
LINIMENTS.
Liniments are medicines designed for external application. The benefits arising from their use depend upon their derivative power, as well as upon the anodyne properties which many of them possess, rendering them efficacious for soothing pain. We cannot mention a more valuable agent of this class than
Dr. Pierce's Compound Extract of Smart-weed. As an external application this preparation subdues inflammation and relieves pain. For all wounds, bruises, sprains, bee-stings, insect and snake-bites, frost-bites, chilblains, caked breast, swollen glands, rheumatism, and, in short, for any and all ailments, whether afflicting man or beast, requiring a direct external application, either to allay inflammation or soothe pain, the Extract of Smart-weed cannot be excelled.
NARCOTICS.
A narcotic is a remedy which, in medicinal doses, allays morbid sensibility, relieves pain, and produces sleep; but which, in overdoses, produces coma, convulsions, and death. The quantity necessary to produce these results varies in different individuals. We shall mention a few of those most frequently employed.
Henbane (Hyoscyamus Niger). The leaves and seeds are used. Henbane, in large doses, is a powerful narcotic and dangerously poisonous. In medicinal doses, it is anodyne and antispasmodic; it allays pain, induces sleep, and arrests spasms. Dose—Of the fluid extract, five to ten drops; of the solid extract, from one-half to one grain; of the concentrated principle, Hyoscyamin, from one-twelfth to one-fourth of a grain.
Indian Hemp (Cannabis Indica). An East Indian plant. Dose—Of the extract, from one-fourth to one-half grain, of the tincture, from three to eight drops; of the fluid extract, from two to five drops. The plant known as Indian Hemp, growing in this country, possesses very different qualities.
