Tinctura Ammoniae Composita. Lond. Compound Tincture of Ammonia

"Take of mastick, two ounces; rectified spirit, nine fluid ounces; oil of lavender, fourteen minims; oil of amber, four minims; strong solution of ammonia, a pint. Macerate the mastick in the spirit, that it may be dissolved, and decant the clear tincture; then add the other articles, and shake all together."

In the accredited translation of the Pharmacopoeia by Mr. Phillips, the quantity of mastick ordered is two drachms, a quantity more likely to be taken up by the spirit than that ordered by the College in the Latin edition of its work. The preparation is nearly the same as the spiritus ammoniae succinatus of the last Pharmacopoeia; and is intended to resemble the Eau de Lace, which, however, contains no oil of amber.

Medical properties and uses. - This tincture is stimulant and antispasmodic : but it is seldom used; and in fact as it contains so little oil of amber, it possesses no advantages over the aromatic spirit of ammonia. The Eau de Luce is regarded almost as a specific for the bite of the Cobra de Capella. The dose is from v. to xx., in a glassful of water.

"Take of balsam of tolu, one ounce; rectified spirit, a pint. Digest in a close vessel until the resin (balsam) is dissolved, then filter."

Tincture of balsam of tolu is scarcely ever used except on account of its agreeable flavour. As it is decomposed by water, it is necessary to triturate it with mucilage, to enable it to mix it with any aqueous fluid. It is chiefly used for making the syrup.
