MAGNESII SULPHAS—SULPHATE OF MAGNESIUM.
(epsom salt.)
Formula.—MgS0,7H.,0.
Derivation.—Epsom Salt is obtained by the action of sulphuric
acid on magnesite, the siliceous hydrate of magnesium. It is in
the form of small, colorless crystals, which effloresce on exposure
to the air, and are very soluble in water. It is odorless, but has
a very bitter taste.
Medical Properties and Action.—Sulphate of magnesia is a re-
frigerant purgative, safe and mild in its action, and is perhaps
more commonly employed as a cathartic than any other. It is at
times combined with other agents.
Therapeutic Uses.—Sulphate of magnesia is administered as a
saline purgative in acute inflammatory and febrile affections, to
depress the arterial tension, and also to relieve the kidneys when
they are hyperaemic ; hence it is a valuable remedy in renal and
cardiac dropsy, constipation of lead colic, acute dysentery, dys-
pepsia with constipation, etc., etc.
Dose.—Of sulphate of magnesia, 5j to 5j? in water or carbonic
acid water.
Dental Uses.—Sulphate of magnesia is employed internally in
dental practice, to reduce the arterial tension in acute inflam-
mations of the dental organs, such as acute pulpitis, acute perio-
dontitis, etc.
To disguise the bitter taste of Epsom salts, the following for-
mula may be employed :
