CHAP. 13. (3).—AMPHIBIOUS ANIMALS. CASTOREUM: SIXTY-SIX
REMEDIES AND OBSERVATIONS.
The might of Nature, too, is equally conspicuous in the
animals which live upon dry land as well;
1 the beaver, for
instance, more generally known as "castor," and the testes
2 of
which are called in medicine "castorea." Sextius, a most
careful enquirer into the nature and history of medicinal substances,
assures us that it is not the truth that this animal,
when on the point of being taken, bites off its testes: he informs
us, also, that these substances are small, tightly knit,
and attached to the back-bone, and that it is impossible to
remove them without taking the animal's life. We learn from
him that there is a mode of adulterating them by substituting
the kidneys of the beaver, which are of considerable size,
whereas the genuine testes are found to be extremely diminutive:
in addition to which, he says that they must not be taken
to be bladders, as they are two in number, a provision not to be
found in any animal. Within these pouches,
3 he says, there
is a liquid found, which is preserved by being put in salt; the
genuine castoreum being easily known from the false, by the
fact of its being contained in two pouches, attached by a single
ligament. The genuine article, he says, is sometimes fraudulently
sophisticated by the admixture of gum and blood, or
else hammoniacum:
4 as the pouches, in fact, ought to be of
the same colour as this last, covered with thin coats full of a
liquid of the consistency of honey mixed with wax, possessed
of a fetid smell, of a bitter, acrid taste, and friable to the
touch.
The most efficacious castoreum is that which comes from
Pontus and Galatia, the next best being the produce of Africa.
When inhaled, it acts as a sternutatory. Mixed with oil of
roses and peucedanum,
5 and applied to the head, it is productive
of narcotic effects—a result which is equally produced by
taking it in water; for which reason it is employed in the
treatment of phrenitis. Used as a fumigation, it acts as an
excitant upon patients suffering from lethargy: and similarly
employed, or used in the form of a suppository, it dispels hysterical
6
suffocations. It acts also as an emmenagogue and as
an expellent of the afterbirth, being taken by the patient, in
doses of two drachmæ, with pennyroyal,
7 in water. It is employed
also for the cure of vertigo, opisthotony, fits of trembling,
spasms, affections of the sinews, sciatica, stomachic
complaints, and paralysis, the patient either being rubbed with
it all over, or else taking it as an electuary, bruised and incorporated
with seed of vitex,
8 vinegar, and oil of roses, to the
consistency of honey. In the last form, too, it is taken for the
cure of epilepsy, and in a potion, for the purpose of dispelling
flatulency and gripings in the bowels, and for counteracting the
effects of poison.
When taken as a potion, the only difference is in the mode
of mixing it, according to the poison that it is intended to
neutralize; thus, for example, when it is taken for the sting
of the scorpion, wine is used as the medium; and when for
injuries inflicted by spiders or by the phalangium,
9 honied
wine where it is intended to be brought up again, and rue
where it is desirable that it should remain upon the stomach.
For injuries inflicted by the chalcis,
10 it is taken with myrtle
wine; for the sting of the cerastes
11 or prester
12 with panax
13 or
rue in wine; and for those of other serpents, with wine only.
In all these cases two drachmæ of castoreum is the proper
dose, to one of the other ingredients respectively. It is particularly
useful, also, in combination with vinegar, in cases
where viscus
14 has been taken internally, and, with milk or
water, as a neutralizer of aconite: as an antidote to white
hellebore it is taken with hydromel and nitre.
15 It is curative,
also, of tooth-ache, for which purpose it is beaten up
with oil and injected into the ear, on the side affected. For
the cure of ear-ache, the best plan is to mix it with meconium.
16
Applied with Attic honey in the form of an ointment,
it improves the eyesight, and taken with vinegar it arrests
hiccup.
The urine, too, of the beaver, is a neutralizer of poisons,
and for this reason is used as an ingredient in antidotes. The
best way of keeping it, some think, is in the bladder of the
animal.
