ACTION OF HYDRASTIS.

Hydrastis, in moderate doses, acts as a gastric bitter, promot-
ing the appetite, stimulating the gastro-intestinal secretions, and
peristalsis. It increases the flow of bile. It contracts the pe-
ripheral arterioles chiefly, if not entirely, from its action on the
vaso-motor centre in the medulla. In moderate doses it dimin-
ishes the rate and depresses the force of the cardiac contraction,
but the contraction of the arterioles causes a rise of blood-pres-

sure. It is said to increase uterine contractions and to produce
abortion, but this is doubtful. In poisonous doses it still more
depresses the heart, causing a great fall of blood-pressure ; it
produces convulsions similar to those of strychnine, and kills by
paralysis of respiration. Its action is mainly due to the alkaloid
hydrastine. It has been stated that this, before it acts, is oxi-
dized into hydrastinine, but against this is the fact that it is ex-
creted unchanged in the urine.

THERAPEUTICS OF HYDRASTIS.

External. Hydrastis is employed empirically as a local
stimulating application in chronic inflammations, such as un-
healthy ulcers. It is used also as a lotion in hyperidrosis, acne,
and seborrhcea. Any of the preparations may be employed, if
diluted with water.

Internal. The chief use of hydrastis is that it is empirically
administered for chronic inflammations of mucous membranes.
It is said to be especially valuable for uterine affections, partic-
ularly menorrhagia and dysmenorrhoea. It is given to stop uter-
ine haemorrhage and to arrest the growth of uterine tumors. For
all these diseases hydrastinine hydrochlorate has been much used.
Hydrastis is also employed in the chronic gastritis of drunken-
ness, and to a rather less degree in other forms of chronic gastro-
intestinal catarrh. As an injection or lotion it is employed (any
preparation diluted with an equal part of water) for chronic nasal
catarrh, otorrhoea, leucorrhcea, gonorrhoea, and as a mouth wash
in aphthous stomatitis, chronic pharyngitis, etc. Some authors
claim that it is useful for the same diseases of the heart as are
benefited by digitalis. As an antiperiodic, hydrastis is inferior
[but next in value to] quinine.

ACTION AND USES OF VIBURNUM.

Viburnum is believed to be an antispasmodic, diuretic and
tonic. It is especially used in the nervous diseases of pregnancy
and to prevent miscarriage. It has considerable reputation as a
remedy for spasmodic dysmenorrhcea, in the treatment of after-



COLCHICUM. 645

pains, and in menorrhagia. This remedy has been in extensive
use for more than twenty years and is undoubtedly of value.

APIOLUM.

APIOL. (Not official. ) C 12 H M O 4 =22i.48. A substance obtained from
the fruit of Petroselinum sativum (nat. ord. Umbelliferce}. Synonym.
Parsley. Habitat. Southern Europe ; cultivated.

SOURCE. The fruit is exhausted Avith Petroleum Benzin, the solvent
evaporated, the residue treated with strong Alcohol, on the evaporation of
which Apiol is left.

CHARACTERS. A colorless liquid resembling a fixed oil, but not saponi-
fiable, becoming turbid without congealing at 12 C. ; 10.4 F., having an acid
reaction, the odor of parsley, and a pungent taste. Sp. gr., 1.070. Solu-
bility. Easily in Alcohol, Ether, Chloroform, and Glacial Acetic Acid.

Dose, 10 to 15 m ; .60 to i.oo c.c., (in capsules.)

ACTION AND USES OF APIOL.

Apiol in large doses acts as a cerebral and circulatory stim-
ulant. It is useful in amenorrhoea, scanty menstruation and dys-
menorrho2a when administered immediately before the expected
period and these conditions are due to a want of ovarian activity ;
that is, where direct emmenagogues are required.]

COLCHICUM. 647

ACTION OF COLCHICUM.

External. When applied to the skin colchicum acts as an
irritant, causing hyperaemia and smarting, and the dust inhaled
gives rise to sneezing.

Internal. Gastro-intestinal tract. In moderate medicinal
doses colchicum produces no effect on most persons beyond
slightly increasing the secretion of bile, but with others it causes
loss of appetite, and a little purging, nausea and colic. In
larger doses it gives rise, in all persons, to great abdominal pain,
vomiting and profuse diarrhoea with the passage of blood. It is
in fact a powerful gastro-intestinal irritant. There is also
great prostration, the pulse becomes small, rapid, and thready,
the skin cold and bedewed with sweat, and the respiration slow ;
death is due to collapse. It is probable that these results are not,
to any great extent, owing to the effect of colchicine on the heart
or respiration, but that they are merely the consequence of the
severe gastro- enteritis, which, it is well known, will cause fatal
collapse. These effects are produced if colchicine is injected
subcutaneously, a circumstance which shows that this alkaloid i&
an active principle of the drug, and that it is excreted into the
intestine. It is a curious fact that after a certain point, increas-
ing the quantity does not lead to an increase of the symptoms.
In animals the action on the heart is not marked, but diarrhoea
and vomiting are severe.

Nervous system. Medicinal doses have no effect. Even a
fatal dose does not impair consciousness. Cold-blooded animals
bear much larger proportionate doses than warm, but in all, after
large quantities, sensation is paralyzed, and ultimately the spinal
motor centres are powerfully depressed, death taking place from
respiratory paralysis. Colchicine is said to act on muscles like
veratrine.

Kidney. The most discordant statements have been made
about the action of colchicum on the urine, but it has not been
definitely shown that either the quantity or composition, even
in the amount of uric acid, is altered. After death by poisoning,
the alkaloid is found in the blood and in most of the organs of
the body.



648 ORGANIC MATERIA MEDICA.

THERAPEUTICS OF COLCHICUM.

Colchicum is hardly ever used except for gout. Given during
the attack, it most markedly relieves the pain ; in smaller doses
given between the attacks it diminishes their severity. It is often
very useful for dyspepsia, eczema, headache, neuritis, conjuncti-
vitis, bronchitis, and other conditions which, when occurring
in those suffering from gout, are probably related to it. How
it acts is not known. Occasionally it is combined with other
cholagogues, especially if i- is desired to give these remedies to a
person who is the subject of gout. If any symptoms of gastric
or intestinal irritation appear, its use must be discontinued for a
time. As it is a cardiac depressant, those who take it should keep
the bowels well open, lest it accumulate in the body. Hence it
is commonly combined with magnesium sulphate. The seed is
said to be [less] active than the corm. [A well-known formula
is : extract of colchicum root, calomel, powdered aloes, pow-
dered ipecacuanha, of each i gr., .06 gm., with j to y 2 gr. ;
.015 to .03 gm. of extract of mix vomica. ]



GROUP XIV.

The Stearoptens.

The three bodies in this group are white solids, all very closely related to
volatile oils, all are antiseptic (two very powerfully so) and two at least, and
probably all three, are local anaesthetics.

Camphor, Thymol, Menthol.

CAMPHORA.

CAMPHOR. [Synonyms. Gum Camphor, Laurel Camphor, C,0H ]6 O
=151.66. A stearopten (having the nature of a ketone) obtained from Cin-
namomum Camphora) (Linne) Nees et Ebermaier (nat. ord. Laurinetz), and
purified by sublimation. Habitat. China and Japan.

SOURCE. The branches and chipped wood are exposed to the vapors of
boiling water, the volatilized Camphor is condensed, drained and pressed from
the adherent volatile oil (Oil of Camphor), and subsequently refined by subli-
mation in vessels of glass or iron. Camphor is now obtained by tapping the
trees and collecting the exudation.



THE STEAROPTENS. 649

CHARACTERS. White, translucent masses, of a tough consistence and a
crystalline structure, readily pulverizable in the presence of a little Alcohol,
Ether, or Chloroform, having a penetrating, characteristic odor, and a pun-
gently aromatic taste. Sp. gr., 0.995. Burns with a smoky flame. Volatil-
izes slowly at ordinary temperatures. Sublimes entirely when heated. Solu-
bility. Very sparingly soluble in water, but readily soluble in Alcohol, Ether,
Chloroform, Carbon Bisulphide, Benzih, and in fixed and volatile oils. When
Camphor is triturated in about molecular proportions with Menthol, Thymol,
Phenol, or Chloral hydrate, liquefaction ensues.]

COMPOSITION. Camphor is an oxidation product of Pinene (see Oil of Tur-
pentine, [p. 515]), and may also be derived from Cymene found in Oil of Car-
away [see p. 551] and Oil of Eucalyptus [see p. 527]. The [official] cam-
phor is called Laurel Camphor, and is dextro-rotary. Borneol, known as
Borneo, [Sumatra or Barus] Camphor, see p. 557, is often in commerce sub-
stituted for the official camphor, which it closely resembles, is derived from
Dryobalanops \_Camphora\ and known from the official variety by sinking
in water is C IO H 18 O ; that is to say, an alcohol. The common form of Borneol
is dextro-rotary, but laevo-rotary and inactive varieties are known.

taste. Solubility. Nearly insoluble in cold, readily soluble in hot water,
Alcohol, Ether and oils.

Dose, 10 to 30 gr. ; .60 to 2.00 gm.]

ACTION OF CAMPHOR.

External. Camphor, although not a volatile oil, acts very
much like one. Thus it is a direct cutaneous stimulant, dilating
the vessels of the skin, and at first causing a sensation of
warmth, but subsequently a slight degree of local anaesthesia.
It is a feeble antiseptic.

Internal. Gastro-intestinal tract. In the stomach it is
mildly stimulant, dilating the vessels, increasing the flow of
gastric juice and the peristalsis. Hence it is stomachic and car-
minative. It has a slight reflex stimulating effect on the heart.
In medicinal doses it has little action on the intestines.

Absorption. It is quickly absorbed, both from the intestines
and the skin, and two bodies formed in the body from it are
known. One, camphoral (one atom of H in camphor being re-
placed by OH), combines with glycuronic acid and is excreted
in the urine as campho-glycuronic acid. Another, an amido-
derivative, is also found in the urine.

Circulation. It increases the number of leucocytes in the
blood. To a slight extent the heart is excited directly by it in
addition to the reflex stimulation just mentioned. And so the
pulse becomes fuller and stronger ; the rate is not much affected.
The face may be flushed.

Respiration. Probably some camphor or some derivative
from it is excreted by the bronchial mucous membrane, the vas-



THE STEAROPTENS. 651

cularity and secretion of which it consequently stimulates. It
has the reputation of being a feeble expectorant.

Skin. It is a mild diaphoretic. This effect is believed to
be due to the action of the drug on the central nervous system.
Probably some of the camphor is excreted by the skin, for the
sweat may smell of it.

Nervous system. Different people are differently susceptible
to the effects of camphor. Five to ten grains [.30 to .60 gm.]
will in some persons produce a feeling of exhilaration, or in
others a sense of comfort and quietness. Larger doses cause
excitement, giddiness, a slow pulse, and ultimately headache,
burning pain in the stomach, faintness, confusion of ideas, de-
lirium, violent convulsions, insensibility, a small, feeble pulse,
and finally death from collapse. It is a mild antipyretic.

Sexual organs. Camphor is reputed to be an aphrodisiac, but
this is probably incorrect.

THERAPEUTICS OF CAMPHOR.

External. Its stimulating effects make camphor a favorite
ingredient of many liniments. It is constantly rubbed into the
skin in some form or another as a mild irritant or counter-irritant
in, for example, chronic rheumatism, chronic inflammatory indu-
rations, and the slighter chest complaints of children ; and also
in myalgia, neuralgia, lumbago, and sciatica, in which cases, be-
cause of its property of causing local anaesthesia, it relieves pain.
In addition to the pharmacopoeial preparations, a Chloroformum
Camphorse (camphor, 2, dissolved in chloroform, i) may be
used. The liquid preparations with chloral [hydrate,] carbolic
acid, and thymol are excellent local anodynes for neuralgia, and
may be dropped into a tooth to relieve toothache.

Internal. Camphor is used as a carminative, especially in
neurotic subjects. It is a common remedy for a cold in the head,
and is probably beneficial on account of its stimulation of the
circulation and its slight antipyretic and diaphoretic effects.
Many expectorant mixtures contain camphor. It has been given
as an antispasmodic in hysteria and allied conditions, and some
state that it is of use in cholera. [Monobromated Camphor re-

sembles, but is not identical with, the bromides in its therapeu-
tical action, being used as a nervous sedative. Camphoric acid
is successfully administered for colliquative sweating, e.g., that
of pulmonary tuberculosis. The daily amount of from 15 to 75
gr. ; i. to 5. gm., should be given in the evening in divided
doses at short intervals, either dry upon the tongue or in starch
wafers.]
