2. _Compound Decoctions._

DECOCTUM ALOES COMPOSITUM. It resembles the well known _Beaume de vie_,

although less purgative, and is a scientific preparation, constructed

upon the true principles of medicinal combination. Aloes is the base, to

which are added, 1st, sub-carbonate of potass, 2ndly, powdered myrrh,

3dly, extract of liquorice, 4thly, saffron, and after the decoction is

made, 5thly, compound tincture of cardamoms. By the 1st ingredient the

aloes is rendered more soluble; the 2d and 3d suspend the portion not

dissolved, and at the same time disguise its bitterness; the 4th imparts

an aromatic flavour, and the 5th not only renders it more grateful to

the stomach, but prevents any spontaneous decomposition from taking

place. Its taste is improved by keeping. It is a warm, gentle cathartic.

_Form: 80._ DOSE, f℥ss to f℥j. Its operation is different from that of

simple aloes. See _Aloes_. The following substances are incompatible

with it; _strong acids_, _oxy-muriate of mercury_; _tartarized

antimony_; _sulphate of zinc_; and _acetate of lead_; and those salts

which are decomposed by sub-carbonate of potass.

DECOCTUM GUAIACI COMPOSITUM. E. Commonly called _Decoction of woods._

This decoction has fallen into disuse, and deservedly, for it can

possess but little power, except, as a diluent, or demulcent; the water

takes up from the guaiacum only a small portion of extractive matter,

and the virtues of sassafras, if any, must be dissipated. DOSE, f℥ss to

f℥j.

DECOCTUM HORDEI COMPOSITUM.[490] An elegant and useful demulcent, with

an aperient tendency.

DECOCTUM SARSAPARILLÆ COMPOSITUM. L.D. This decoction, which is an

imitation of the once celebrated _Lisbon Diet Drink_,[491] differs

materially from the _Decoct: Guaiaci comp:_ from the addition of the

mezereon root, which renders it diaphoretic and alterative, and useful

in the treatment of secondary syphilis, and chronic rheumatism. DOSE,

from f℥iv to f℥vj three or four times a day.
