Tinctura Assafœtidæ Ammoniata. E.
This is a solution of the fœtid volatile oil of the Assafœtida in the spirit of ammonia; as little else than the odour and flavour of the gum-resin is taken up by the menstruum, it cannot be expected to possess many virtues. Dose, fʒss to fʒi.
SPIRITUS AMMONIÆ SUCCINATUS. L.
This preparation was probably introduced as a substitute of the Eau de luce. It is stimulant and antispasmodic. It will be found, if properly prepared, to retain its milkiness for a considerable time, a circumstance by which its value is appreciated. The substances enumerated under the head of Spir: Ammoniæ Aromat: are also incompatible with this preparation.
SPIRITUS COLCHICI AMMONIATUS. L.
We have in this preparation the specific virtues of the Colchicum, with the stimulant property of the Ammonia; a medicinal combination, which is frequently indicated in practice. Dose fʒss to fʒi, in some aqueous vehicle. The substances enumerated under the history of Spiritus Ammoniæ Aromaticus, are likewise incompatible with this spirit.
SPIRITUS ÆTHERIS AROMATICUS. L.
Æther Sulphuricus cum Alcohole Aromaticus. E.
Elixir Vitrioli dulce. P.L. 1745.
This preparation, which was excluded from the London Pharmacopœia of 1787, is now restored. It consists of Sulphuric Ether one part, rectified spirit two parts, impregnated with aromatics; the presence of spirit is necessary in this preparation, since the volatile oils would be insoluble in the æther without it. Med. Uses. A grateful stimulant.
