Sulphur Antimoniatum Fuscum. D.
_Precipitated Sulphuret of Antimony._
QUALITIES. _Form_, a brilliant orange coloured powder; _Taste_, slightly
styptic, but inodorous. CHEMICAL COMPOSITION. Very complicated
attractions are exerted during the preparation of this substance; the
result of which is an hydro-sulphuret of Oxide of Antimony, with excess
of sulphur. SOLUBILITY. It is quite insoluble in water. USES. According
to the dose, it is diaphoretic, cathartic, or emetic; it is, however,
less certain than many other preparations, and, unless in combination
with mercury, for cutaneous affections, is not very often employed.
INCOMPATIBLE SUBSTANCES. All acids and acidulous salts increase its
emetic properties; when therefore acid is suspected to prevail in the
primæ viæ, it should be combined with soap, magnesia, (_Form: 128_,) or
aromatic confection; on the contrary, the confection of roses, and
vehicles containing acids, should be carefully avoided. FORM OF
EXHIBITION. Pills. DOSE, grs. 1 to v. OFFICINAL PREPARATIONS. _Pilulæ
Hydrargyri Sub-Muriatis_ (=H=) L. ADULTERATIONS. It is often
sophisticated with chalk and other extraneous matter; it ought not to
effervesce with acids; it should be entirely vaporizable by heat, and
its colour should be that of bright orange. A spurious article is
vended, which consists of sulphur and sulphuret of antimony coloured
with Venetian red.
