Uses.—Compound tincture of benzoin is chiefly employed both for its antiseptic and protective effect as a local application to minor wounds, chapped hands or nipples, indolent ulcers, etc. It is the balsamum traumaticum of the older Pharmacopoeias, and may be considered as a simplified form of certain complex compositions, such as baume du commandeur, Wade's balsam, Balsam de Maltha, Friar's balsam, Jesuit's drops, Turlington's balsam, etc., which were formerly in great repute, and are still esteemed by the people, as pectorals and vulneraries. The compound tincture of benzoin is precipitated by water. A variety of court plaster is made by applying to black silk, by means of a brush, first a solution of isinglass, and afterwards an alcoholic solution of benzoin.
It is occasionally employed Internally as a stimulating expectorant in chronic bronchitis. More frequently it is used as an inhalant by adding a teaspoonful of the tincture to a pint of hot water and breathing the vapors; this mode of treatment is especially useful in the early stages of acute bronchitis. It has also been recommended in chronic dysentery with the idea that it would exercise its local action upon the ulcerated surface of the colon, but is of doubtful utility.
Dose, fifteen to sixty minims (0.9-3.75 mils).
