Action, Medical Uses, and Dosage.—A preparation similar to this has been known under various names, as Balsamum traumaticum, Jesuits' drops, Wound balsam, Commander's balsam, Friar's balsam, etc. It is used as an expectorant in old coughs and catarrhs. Compound tincture of benzoin is advised by inhalation, with steam, for the relief of acute and chronic laryngitis, and in chronic bronchial irritation, with free and fetid secretion. It was formerly used as a stimulating application to obstinate ulcers. Internally, the dose is from ½ to 1 or 2 fluid drachms. Turlington's balsam, a well-known remedy, was composed of benzoin, 6 ounces; liquid storax, 2 ounces; Socotrine aloes, ½ ounce; Peruvian balsam, 1 ounce; myrrh, ½ ounce; angelica root, 2 drachms; balsam of tolu, 2 ounces; extract of liquorice, 2 ounces; alcohol, 4 pints. Mix, digest for 10 days, and strain (Jour. of Phila. Col. of Pharm., Vol. V, p. 28). It is an improper application to fresh wounds, though it is often applied to excoriations and abrasions, and to sore nipples, as a protective. It sometimes relieves the itching of chilblains, eczema, and urticaria, and, combined with glycerin, is a useful application for chapped hands and face. This balsam is designed to represent the once popular preparation known by the above-given names, and as Swedish, Persian, Wade's, St. Victor's, and Vervain's balsams.
