Honey 8 oz.
Muriatic acid 1 oz.
Verdigris 1 oz.
Mix over a slow fire.
This liniment may be made stronger by substituting nitrous acid for
muriatic, or by retaining the muriatic, and substituting for the
verdigris one drachm of sublimate. A weaker liniment is made, and a very
useful one, by using two ounces of vinegar instead of the muriatic acid.
(See EGYPTIACUM). Escharotics are applied to foul ulcers, and are
employed to destroy fungous or proud flesh.—_White._
ESCULENT, _s._ Something fit for food.
ESSENCE, _s._ In medicine, the chief properties or virtues of any
simple, or composition, collected into a narrow compass.
_Essence of mustard_, composed of camphor, oil of rosemary, and
oil of turpentine, is a good stimulating embrocation.
ESSENTIAL, _a._ Necessary; important in the highest degree,
principal; pure, highly rectified. _Essential oils_ are obtained
by distillation from mint, pennyroyal, peppermint, lavender,
caraway seeds, anise-seeds, juniper berries, lemon-peel,
sandal-wood, &c.
ESTRAPADE, _s. obs._ The defence of a horse that will not obey, but
rises before, and yerks furiously with his hind legs.
ESTUARY, _s._ An arm of the sea; the mouth of a lake or river in
which the tide ebbs and flows.
ETHER, _s._ An element more fine and subtile than air; a chemical
preparation. Sulphuric ether is a powerful stimulant, and must
be given with caution. White mentions an instance of two ounces
destroying a horse.
ETHIOP’S MINERAL, _s._ A preparation made by rubbing equal parts of
quicksilver and flower of sulphur together, until the mixture
becomes black, and the quicksilver invisible.
Ethiop’s mineral, though generally considered as an inert medicine, is
possessed of considerable virtue, and is probably the best mercurial in
cases where it is necessary to introduce mercury into the circulation,
as in farcy, glanders, obstinate mange, &c. It should be given in a dose
of two or three drachms in the horse’s corn, once or twice a day, until
an offensive smell is perceived in the horse’s breath, or he is found to
stale more than usual; these symptoms indicate that the mercury has got
into the circulation. The disorder for which it is given may, at this
period, be expected to yield to the mercurial influence, and may not
require a further continuance of the medicine.—_White._
EUPHORBIUM, _s._ A plant; a gum resin that exudes spontaneously from
a large oriental tree.
Euphorbium is brought to us in small drops, of a pale yellow colour,
which are generally mixed with woody and other extraneous matter. It is
used as an external application, and generally employed in the form of
tincture; sometimes it is mixed into an ointment with hog’s-lard,
mercurial ointment, oil of origanum, oil of bay, &c., being previously
reduced to a fine powder. It is also frequently an ingredient in strong
blisters, to which it proves a powerful auxiliary. In whatever form
euphorbium is employed, it proves extremely acrimonious and stimulating,
and is useful in reducing callous swellings of the back sinews, curbs,
windgalls, &c.
The tincture is made by steeping one ounce of the powder in four or six
ounces of rectified or proof spirit, frequently shaking the bottle which
contains the mixture, and keeping it in a warm place; after eight or ten
days to be strained off, and kept well corked.—_White._
EWE, _s._ The she sheep.
EXFOLIATION, _s._ The process by which the corrupted part of the
bone separates from the sound.
EXPECTORATION, _s._ The act of discharging from the breast; the
discharge which is made by coughing.
EXPECTORANTS, _s._ Medicines that increase the discharge of mucus,
and thus relieve coughs and impeded breathing. In costive cases
they should be assisted by clysters and bran mashes.
