cylic acid has been given to render the urine acid in cases of alka-
line urine and cystitis, but there are better remedies for this
purpose. It has also been given in cases of gallstone with the
object of rendering the urine less viscid.

[Aspirin (not official) is acetyl salicylic acid, which occurs as
a white, insoluble, crystalline powder, or in needles, of an agree-
able taste. In an alkaline fluid it breaks up and sets free salicylic
acid. It has been employed for acute polyarticular rheumatism
in the same doses as sodium salicylate, over which it is believed
to possess the advantage of not deranging digestion.


VOLATILE OIL OF BETULA. Synonym. Oil of Sweet Birch.
A volatile oil obtained by distillation from the bark of Betula lenta Linn6
(Sweet Birch) ; (nat. ord. Betulacece}. Habitat. Northern United States. It
is identical with Methyl Salicylate (CH 9 C 7 H 5 O 3 =I5I.64), and nearly identi-
cal with Oil of Gaultheria.

CHARACTERS. It has the same properties and conforms to the same reac-
tions and tests as Methyl Salicylate (see Methyl Salicylas ; also Oleum Gaul-

Dose, i to 5 m. ; .06 to .30 c.c.


OIL OF GAULTHERIA. Synonym. Oil of Wintergreen. A vola-
tile oil distilled from the leaves of Gaultheria procumbens Linn6 (Winter-
green) ; (nat. ord. Ericaceat), consisting almost entirely of Methyl Salicylate
(CH S C,H 5 O,=I5I.64) and nearly identical with Volatile Oil of Betula.
Habitat. North America, west to Minnesota, and south to Georgia.

CHARACTERS. A colorless or yellow, or occasionally reddish liquid, hav-
ing a characteristic, strongly aromatic odor, and a sweetish, warm and aromatic
taste. Sp.gr.: 1.175 to 1-185. Boiling point: 2l8 to 221 C. (424.4
F. to 429.8 F. ). It deviates polarized light slightly to the left. In other


respects it has the same properties and conforms to the same reactions and
tests as Methyl Salicylate (see Methyl Salicylas ; also Oleum Betulse Volatile).
Dose, i to 5 m. : .06 to .30 c.c.


Spiritus Gaultheriae. Spirit of Gaultheria. Oil of Gaultheria,
50 ; Alcohol, 950.

Dose, i to 2 fl. dr. ; 4. to 8. c.c.

METHYL SALICYLAS. - <&*JL Y\^^^1r><^*>~*-
METHYL SALICYLATE. CH 3 C 7 H 5 O 3 =I51. 64. Synonym.
Artificial (or Synthetic) Oil of Wintergreen. Methyl Salicylate, producea
synthetically by distilling Salicylic Acid, or a Salicylate, with Methyl Alcohol
and strong Sulphuric Acid.

CHARACTERS. A colorless or slightly yellowish liquid, having the char-
acteristic, strongly aromatic odor and the sweetish, warm and aromatic taste
of the Oil of Gaultheria, with the essential constituent of which it is identical.
It is wholly identical with Volatile Oil of Betula (see Oleum Betulae Volatile).
Sp. gr. : 1.183-1.185. Boiling point : 2i9-22i C. (426.2-429.8F.). It
is optically inactive. Solubility. In all proportions in Alcohol, Glacial Ace-
tic Acid, or Carbon Bisulphide.
Dose, i to 5 m. ; .06 to .30 c.c.


The action of these substances is the same as of salicylic acid.
When taken in moderate quantities, they are, like that acid,
broken up and eliminated as salicyluric acid. It is asserted that
methyl salicylate can be produced of more uniform quality and
is more certain and definite in its action than either of the nat-
ural oils. The uses of these drugs is the same as of salicylic
acid, and they possess the additional advantage that they are not
liable to contamination with impurities (ortho- and paracreo?otic
acids), the former of which is a powerful cardiac depressant ;
both are found in the artificial salicylic acid.]


SALOL. [C 6 H 5 C 7 H 5 O 3 =2I3.49. Synonym. Phenyl Salicylate. The
Salicylic Ether of Phenol.

SOURCE. By heating Salicylic Acid with Phenol in the presence of Phos-
phorous Pentachloride ; this action dehydrates and withdraws the elements of
water, and unites the Phenyl group with the Salicylic \cid radical.



CHARACTERS. A white, crystalline powder, odorless, or having a faintly
aromatic odor, and almost tasteless. Permanent in the air. Solubility.
Almost insoluble in water ; soluble in 10 parts of Alcohol ; also soluble in 0.3
part of Ether, and readily in Chloroform, and in fixed or volatile oils.

Dose, 5 to 30 gr. ; .30 to 2.00 gm.]


External. It is an antiseptic, and when mixed with talc
( i to 5 ) may be used as a dusting powder.

Internal. In the body [presumably in the small intestine)
salol splits up into [phenol, about 36, and salicylic acid, 64
per cent.] and the former may render the urine dark. In rheu-
matic fever it is efficacious on account of the salicylic acid it
contains, [although somewhat slower in action] but it has no
advantage over salicin or salicylic acid, and the carboluria may
be troublesome.

[It is an antiseptic, and since this decomposition takes place
in the alkaline fluid, it has been used as an intestinal antiseptic
in acute diarrhcea, dysentery, cholera and other diseases ; also in
affections of the urinary tract.] For the last the following is a
good way of prescribing it : Salol, i ; Almond Oil, 2 ; Pow-
dered Acacia, i ; Syrup, 2 ; water, 24. The emulsion should
be made in a warm mortar with water at 150 F. [65.5 C.
It is a remedy of very great value in the treatment of typhoid
fever, for by the active disinfection of the contents of the intes-
tine and of the ulcerations, it favors their healing and prevents
reinfection, thus lowering temperature, diminishing the liability
to relapse and to permanent damage to tissues. It is the logical
treatment, because it destroys the cause of the symptoms, at their
point of origin. On account of the large proportion of phenol
which it contains it is more dangerous than the corresponding
amount of salicylic acid, and it is especially to be used, with
great caution if the kidneys are diseased. Sometimes, in fever,
on account of the lessened alkalinity of the intestinal contents
it is not decomposed into its constituents, and for that reason
becomes very much less effective. In this case an alkali should
be administered at the same time.



SALOPHEN. ( Not official. )C 6 H 4 (OH)CO 2 C 6 H 4 NHCOCH s =27o.40.
Synonym. Acetylparamidophenol Salicylate.

SOURCE. From Paranitrophenol Salicylate by a complicated process, and
purifying by crystallization from Alcohol.

CHARACTERS. Minute white scales, free from odor or taste. It contains
50.9 per cent, of Salicylic Acid. Solubility . Almost insoluble in water;
freely soluble in Alkalies, Alcohol and Ether.

Dose, 5 to 15 gr. ; .30 to i.oo gm.


In a warm alkaline solution salophen is broken up into sali-
cylic acid and acetylparamidophenol, the latter being harmless.
It is decomposed in the intestines, even when given hypoder-
matically. It is used as a substitute for salicylic acid in acute
rheumatism, and as an intestinal antiseptic. It is probably quite
as efficient, and much safer than salol. The fact that it is taste-
less renders it easy of administration.]

Acetic Acid ; also soluble in 3 times its volume of a mixture of 19 volumes
of Alcohol and I volume of water (absence of more than about 5 per cent,
of most other fixed oils).

COMPOSITION. The chief constituents are (i) Ricinolein, C 3 H 5 (C 18 H S4
O 3 ) 3 , which is the Ricinoleic Acid (CjgH^Og), Glyceride.] This constitutes
the chief fiulk. (2) Other fixed oils, as palmitin, stearin, etc. (3) Possibly
an alkaloid, Ricinine,r\ol purgative. (4) According to some authorities an
active principle which has not yet been isolated.

[Castor oil is contained in Collodium Flexile, Linimentum Sinapis Com-
positum, Pilulae Antimonii Composite and Unguentum Hydrargyri Oxidi Rubri.

Dose, ^ to 2 fl. oz. ; 8. to 60. c.c.]


Castor oil seeds are not official, but it is important to recognize them.
They are [17 mm.] long and [8 mm.] wide, ovoid, flattened. The seed is
prolonged into a sharp beak. Epidermis shiny gray, marked by brownish
bands and spots. Kernel white. They contain 50 per cent, of the oil, and
an acrid substance which makes them poisonous. Three Castor oil seeds have
been known to kill an adult man. [Quite likely the seeds are not poisonous
when matured.]


External. Castor oil is, like olive oil, protective and
sedative, and may be used to drop into the eye when the con-
junctiva is inflamed, and as a solvent for homatropine, but this
solution is occasionally a little irritating.

Internal. Gastro-intestinal tract. The so-called [unpleas-
ant taste] of castor oil is mostly due to the smell, and is not
noticed much if the nose is held when the oil is drunk. Medici-
nal doses produce no effect on the stomach. Reaching the in-
testine the oil is an excellent simple laxative or mild purga-
tive, acting in about five hours, and causing no griping nor sub-
sequent constipation. The motion is soft, but not liquid. Castor
oil will purge even when rubbed into the skin. How it acts is
unknown [but it is said to stimulate unstriped muscular fibre
whenever found.] It has been thought that the [ricinolein
(ricinoleic acid glyceride)] in the oil is decomposed in the duo-
denum, and the ricixioleic acid purges, but this is probably in-
correct. The most likely view is that the oil contains some
purgative principle which has not yet been isolated. Probably
the seeds contain much more of this than the oil, for they are
ten times more purgative, a fact which it is impossible to explain
if it is the ricinoleic acid which purges. Castor oil will purge
when given per rectum.

Mammary glands. [The leaves] applied locally to the breasts
are said to be galactagogue.


Castor oil is perhaps the best simple purgative we have, and
is very useful in cases in which there is slight temporary consti-
pation. Being mild in its action it is very suitable for getting
rid of undigested food that is causing diarrhoea, and a dose of


castor oil with a minute quantity of laudanum in it is a favorite
remedy for certain forms of diarrhoea. It is also especially con-
venient in pregnancy, after delivery, and when in any abdominal
disease, as typhoid fever, peritonitis, or when, after abdominal
operations, the irritation caused by the faeces makes it absolutely
necessary to get the bowels open. Also, it is very useful for
children, or for very old or infirm persons, or for those suffering
from piles or fissures. It is a good purgative to give before and
after the use of anthelmintics [aspidium being excepted. It
should not be given during the later months of pregnancy owing
to its action on unstriped muscle fibres.]

Its [nauseous taste] is the only objection to it. As already
mentioned, this can largely be overcome by holding the nose,
and there are many forms of castor oil in the market so prepared
as to be almost colorless and odorless. It may be taken in cap-
sules, but they are bulky. Lemon juice or coffee conceals the
taste to some extent, or the oil may be added to a teaspoonful
[4. c.c.] of peppermint water, and then a little brandy added till
the oil neither sinks nor [floats] . If the inside and rim of the
glass are moistened with the vehicle, the oil, which should, if
possible, be between two layers of the vehicle, is hardly tasted.
[It is best administered in the beverage known as sarsaparilla.]

As an enema (castor oil, i ; warm olive oil, 5 ; mixed thor-
roughly) it is useful when a mild injection is required.

Breasts. The leaves of the castor-oil plant applied to the
breasts will sometimes induce the secretion of milk. A fluid ex-
tract of them [not official] may also be taken three or four times

a day.


RHUBARB. [The root of Rheum offidnale Baillon (nat. ord. Poly-
gonactce]. Habitat. Western and Central China.

CHARACTERS. In cylindrical, conical or flattish segments, deprived of the
dark brown, corky layer, smoothish or somewhat wrinkled, externally covered
with a bright yellowish-brown powder, marked with white, elongated meshes,
containing a white, rather spongy tissue, and a number of short reddish-brown
or brownish-yellow striae ; compact, hard ; fracture uneven ; internally white,
with numerous red, irregularly curved and interrupted medullary rays, which
are radially parallel only near the cambium line ; odor somewhat peculiar,
aromatic; taste bitter, somewhat astringent.


COMPOSITION. The chief constituents are (I) Chrysophan,
which yields Chrysophanic Acid, C 15 H JO O 4 , about 3 per cent. Synonyms.
Rhein. Chrysarobin, see Chrysarobinum. ] It is,not known whether, [in the
living plant], Rhubarb contains any Chrysophanic Acid, for when kept the
Chrysophan quickly oxidizes to Chrysophanic Acid. The purgative properties
are due to Ghrysophan which also gives the yellow color. (2) [Erythroretin.
(3) Emodin. (4) Phaoretin. (5) Aporctin.~\ (6) Rheotannic Acid, C 26 H 26 O U ,
to which the astringency of Rhubarb is due. (7) Lime Oxalate, 35 per cent.,
to which the grittiness is due.

IMPURITIES. English Rhubarb ; different taste, smell, and excess of
starch. Turmeric, which is turned brown by Boric Acid.

External. Probably rhubarb would have, to a mild degree,
the same action as [chrysarobin] , but it is never applied ex-

Internal. Alimentary canal. In the mouth, rhubarb in-
creases the flow of saliva ; and in the stomach, in small doses, it,
like any other bitter substance, stimulates the flow of gastric
juice, and the vascularity and peristaltic movements of the
stomach. It is, therefore, a stomachic, and will aid digestion.
In large doses it causes purgation, producing in from four to
eight hours a liquid motion, colored yellow by the [chrysarobin] .
