ACTION AND USES OF CHENOPODIUM.

Wormseed is one of the most efficient anthelmintics, particu-
larly against Ascarides, but it should be followed by a cathartic.]

CLASS III. PARASITICIDES USED FOR PEDICULI.
STAPHISAGRIA.

STAPHISAGRIA. [Synonym. Stavesacre. The seed of Delphinium
Staphisagria Linne (nat. ord. Ranunculacea}. Habitat. Basin of the Med-
iterranean ; cultivated.

CHARACTERS. About 5 mm. long, 3 or 4 mm. broad, flattish-tetrahedral,
one side convex, brown or brownish-gray, with reticulate ridges, containing a
whitish, oily albumen and a straight embryo ; nearly inodorous ; taste bitter
and acrid. ]

COMPOSITION. The chief constituents are (i) Delphinine, [C-^Hj-NOg,
a white, crystalline, poisonous alkaloid, soluble in Alcohol, Ether and Chloro-
form, resembling Aconite in its action. (2) Delphinoidine, C^HggNjOj, an
amoi phous alkaloid ; solubility as of Delphinine. (3) Delphisine,C^H^f) v
a crystalline alkaloid of the same solubility. (4) Staphisagrine , C^H^NOj,
an alkaloid but slightly soluble in water. (5) Fixed oil, 25 per cent]

ACTION AND THERAPEUTICS OF STAPHISAGRIA.

[Staphisagria] is only used as a parasiticide to kill pediculi.
The affected part is rubbed with the ointment, [B. P., 4 ; yel-
low wax, 2 ; benzoinated lard, 17] which, in the case of pediculi
vestimentorum, is allowed to soak, day and night, into the gar-
ments next to the skin, for the parasite inhabits them. It is
often employed, but it will be remembered that many other
parasiticides for pediculi have been mentioned (see p. 51).

PICROTOXINUM.

PICROTOXIN. C 30 H 34 O ls [=6oo.58. A neutral principle obtained
from the seed of Anamirta paniculata Colebrooke (nat. ord. Menispermaceee).
Synonyms. Cocculus Indicus. Fishberry. Habitat. East India.



630 ORGANIC MATERIA MEDICA.

SOURCE. Obtained by exhaustion with hot Alcohol, evaporation and puri-
fication by re-crystallization, after decolorizing with Animal Charcoal.

CHARACTERS. Colorless, flexible, shining, prismatic crystals, or a micro-
crystalline powder, odorless, and having a very bitter taste ; permanent in the
air. Solubility. Soluble in 240 parts of water, and in 9 parts of Alcohol ;
also soluble in solutions of the alkalies, and in acids. Very slightly soluble in
Ether or Chloroform. ]

Dose, T ^j to ^y gr. ; [.0005 to .001 gm.]

ACTION OF PlCROTOXIN.

External. Picrotoxin is very destructive to lower forms of
life, and is therefore antiparasitic.

Internal. It is a powerful poison, causing severe gastro-in-
testinal irritation, collapse, lightheadedness, convulsions, hyper-
pyrexia, slowing of the pulse and stimulation of the respiratory
centre. Death results from asphyxia, partly due to convulsions
and partly to ultimate paralysis of the respiratory centre.

THERAPEUTICS OF PICROTOXIN.

External. An ointment of the seeds in lard [i to 6] has
been applied to the scalp to kill pediculi. It must be employed
with caution, for this strong poison can be absorbed if the skin
be broken. It is an expensive ointment.

Internal. Picrotoxin is used empirically, to check the
night sweating of phthisis. A single dose should be given in
the evening. Its action is uncertain, but sometimes it succeeds.
Many other diseases have been treated with it, but there is no
evidence that it has benefited them. [Tablets] , each containing
T&T of a grain [.0006 gm.], are prepared for subcutaneous injec-
tion. One should be dissolved in a few drops of water imme-
diately before use.

quinone. (2) Ericolin [C 10 H 16 O, a bitter, crystalline glucoside. (3) Ursone,
a tasteless neutral body. (4) Tannic Acid, 6 to 7 per cent. (5) Gallic Acid.

INCOMPATIBLES. Iron, lead and silver salts, alkaloids, and gelatin.]

Dose, % to i dr. ; [i. to 4. gm.]

2. Extractum Uvae Ursi Fluidum. Fluid Extract of Uva Ursi.
By maceration and percolation with Glycerin, Alcohol and Water, and
evaporation.

Dose, j^ to i fl. dr. ; i. to 4. c.c.]

ACTION OF UVA URSI.

Uva ursi is a well-marked diuretic, and is astringent and
disinfectant to the urinary mucous membrane. Its dis-
infectant action is probably due to the decomposition of the ar-
butin into glucose and hydroquinone, for after uva ursi is given
this substance is found in the urine, and it is a very energetic
antiseptic. This decomposition must take place in the kidneys,



632 ORGANIC MATERIA MEDICA.

for hydroquinone is a powerful poison. Against this being the
reason of the disinfectant action of the uva ursi, it is urged that
giving arbutin does not disinfect the urine ; but others deny this,
and the probability is that the first-mentioned view is correct.
Arbutin itself is a diuretic. The urine may be a pale greenish
to dark greenish -brown color. Hydroquinone is also found in
the urine in carbolic acid poisoning (see p. 332). [The fluid
extract is an excellent remedy for ardor urinae of acute gonor-
rhoea.] The astringent action of uva ursi on the urinary tract is
usually ascribed to the gallic and tannic acids, but as these are
not remote astringents this is most likely wrong.

THERAPEUTICS OF UVA URSI.

Uva ursi is given to disinfect the urine in the same class of
cases as buchu that is to say, in pyelitis, cystitis and gonorrhoea.

USES AND ACTION OF HOREHOUND.

Horehound, used as a decoction or an infusion, is in moder-
ate doses a diuretic, in large doses laxative, and may be so given
as to increase the action of the skin and kidneys ; but its action
is not marked. It is probably also a bitter stomachic. Confec-
tion of horehound slowly dissolved in the mouth relieves the
relaxed throat of public speakers.]

matic Spirit of Ammonia, 2. Dose, 10 to 60 m. ; .60 to 4.00 c.c.]

ACTION OF ERGOT.

\

The chief action of cornutine is on voluntary and involun-
tary muscle, which is stimulated to contract, hence prolonged
muscle curves, increased peristalsis of the [intestines], tonic
contraction of the uterus, and consequent rise of blood-pressure.
It also causes convulsions. Sphacelic acid also acts directly on
the muscular tissue of arterioles and the uterus, causing it to con-
tract, and in addition it produces an actual thickening of the
walls of the arterioles. These substances are rarely given sepa-
rately, and the following account refers to the action of ergot
itself.

External. None.

Internal. Gastro-intestinal tract. The unstriped muscle
of the intestine is stimulated by ergot, and this leads to greatly
increased peristaltic movements, sometimes strong enough* to
cause relaxation of the bowels. The vessels of the intestine are
constricted, in part because of the contraction of their own
muscular fibres, and in part because of the contraction of those
of the intestinal muscular coat. The result is that the intestine
is blanched.

Blood. The active principles of ergot are readily absorbed,
but they are not known to produce any effect on the blood.

Heart. The activity of the heart muscle is depressed by
ergot ; therefore the rate of the pulse falls, and consequently at
first the blood -pressure may fall.

Vessels. But the fall of blood-pressure is soon followed by a
great rise, and this is due to the general contraction of the
arteries all over the body ; they can, in some parts, be seen to
become smaller. The rise of pressure is most marked in the
pulmonary artery, and here there is no primary fall. The veins



VEGETABLE DRUGS ACTING ON UNSTRIPED MUSCLE. 639

are contracted to a less extent. This vascular contraction is
less if the spinal cord is destroyed, from which it is fair to infer
that it is partly due to the action of ergot on the vaso-motor
centres in the cord, but the drug acts largely directly on the
muscular coat of the vessels. [Because it contracts the arterioles
it is haemostatic.] If the ergot be taken for a long time the
contraction of the arterioles, together with the associated thick-
ening of their walls produced by sphacelic acid, lead to gan-
grene of various parts of the body, and this was a prominent
symptom of the ergotism (chronic poisoning by ergot) which
used to be seen in the very poor who could get no better food
than rye infected with Claviceps purpurea. Enormous single
doses of ergot appear to paralyze the vaso-motor centres, and
then the blood-pressure falls from vascular dilatation and cardiac
depression.

Nenious system. Medicinal doses, or even an enormous single
dose, very rarely affect the nervous system, but if ergot be taken
for a long time a peculiar train of symptoms sets in ; they con-
stituted the second variety of chronic ergotism in the [times]
when diseased bread was eaten. The sufferer first complained
of itching and tingling, and a sensation of insects running over
the skin ; this was followed by numbness and local anaes-
thesia. These symptoms first appeared in the hands and feet,
but spread over the whole body. They were followed by tonic
contractions of various muscles, especially those of the ex-
tremities. The muscular power was lessened, and the gait was
staggering. Dimness of vision and loss of hearing, and epi-
leptiform convulsions were sometimes present. This variety
of ergotism was usually accompanied by vomiting and diarrhoea.
Death occurred from [exhaustion].

Uterus. Ergot powerfully excites the pregnant uterus of
women and lower animals to contract and expel its contents. It
is therefore called an ecbolic. It is not decided whether this
effect is due to the action of the drug on the organ itself or on
the spinal centres. Ergot has very little power to cause contrac-
tion of the unimpregnated uterus.

The flow of urine, of saliva, of sweat, and of milk is dimin-



640 ORGANIC MATERIA MEDICA.

ished by ergot, probably because of the general vascular con-
striction.

THERAPEUTICS OF ERGOT.

The chief use of ergot is to cause efficient contraction of the
uterus after labor, and so to diminish the risk of post-partum
haemorrhage. If there is any likelihood of profuse bleeding it
should be given subcutaneously, so that it may act rapidly.

Ergot should [not] be administered before the child is ex-
pelled, for the contraction produced by it not only gradually
becomes more severe, but more prolonged, so that ultimately the
uterus remains tightly contracted for several minutes ; that is, of
course, dangerous to the life of the child, and if the resistance be
very great, may lead to rupture of the uterus. [The modern
practice is to forbid its use until after the expulsion of the
placenta.]

This drug has often been given as a haemostatic in haemoptysis
and other haemorrhages from different parts of the body. Some
authors claim great success. Frequently it fails, and it may, by
the general rise of blood-pressure, do more harm than good. It
is difficult to [estimate] its value, for so many haemorrhages \vill
stop, even if no drugs are given. It has been used to check the
night-sweats of phthisis, and as an antigalactagogue.

It is often desirable to combine the [fluid] extract of ergot
with [ferric] chloride. Because of the tannic acid in the ergot
an inky mixture results ; but this may be clarified by the addition
of a little citric acid, and the taste may be covered with chloro-
form water.
