CHAP. 51.—RUE: EIGHTY-FOUR REMEDIES.
One of the most active, however, of all the medicinal
plants, is rue.
1 The cultivated kind has broader leaves and
more numerous branches than the other. Wild rue is more
violent in its effects, and more active in every respect. The
juice of it is extracted by beating it up, and moistening it
moderately with water; after which it is kept for use in
boxes of Cyprian copper. Given in large doses, this juice has
all the baneful effects of poison,
2 and that of Macedonia more
particularly, which grows on the banks of the river Aliac-
mon.
3 It is a truly wonderful thing, but the juice of hemlock
has the property of neutralizing its effects. Thus do we find
one thing acting as the poison of another poison, for the juice
of hemlock is very beneficial, rubbed upon the hands and
[face]
4 of persons employed in gathering rue.
In other respects, rue is one of the principal ingredients
employed in antidotes, that of Galatia more particularly.
Every species of rue, employed by itself, has the effect also of
an antidote, if the leaves are bruised and taken in wine. It
is good more particularly in cases of poisoning by wolf's bane
5
and mistletoe, as well as by fungi, whether administered in the
drink or the food. Employed in a similar manner, it is good
for the stings of serpents; so much so, in fact, that weasels,
6
when about to attack them, take the precaution first of protecting
themselves by eating rue. Rue is good, too, for the
injuries by scorpions and spiders, the stings of bees, hornets,
and wasps, the noxious effects produced by cantharides and
salamanders,
7 and the bites of mad dogs. The juice is taken
in doses of one acetabulum, in wine; and the leaves, beaten
up or else chewed, are applied topically, with honey and
salt, or boiled with vinegar and pitch. It is said that people
rubbed with the juice of rue, or even having it on their person, are
never attacked by these noxious creatures, and that
serpents are driven away by the stench of burning rue. The
most efficacious, however, of all, is the root of wild rue, taken
with wine; this too, it is said, is more beneficial still, if
drunk in the open air.
Pythagoras has distinguished this plant also into male and
female, the former having smaller leaves than the other, and
of a grass-green colour; the female plant, he says, has leaves
of a larger size and a more vivid hue. The same author, too,
has considered rue to be injurious to the eyes; but this is an
error, for engravers and painters are in the habit of eating it
with bread, or else nasturtium, for the benefit of the sight;
wild goats, too, eat it for the sight, they say. Many persons
have dispersed films on the eyes by rubbing them with a mixture of
the juice of rue with Attic honey, or the milk of a
woman just delivered of a male child: the same result has
been produced also by touching the corners of the eyes with
the pure juice of the plant. Applied topiclly, with polenta,
rue carries off defluxions of the eyes; and, taken with wine,
or applied topically with vinegar and rose oil, it is a cure for
head-ache. If, however, the pain attacks the whole of the
head,
8 the rue should be applied with barley-meal and vin-
egar. This plant has the effect also of dispelling crudities,
flatulency, and inveterate pains of the stomach; it opens the
uterus, too, and restores it when displaced; for which purpose
it is applied as a liniment, with honey, to the whole of the
abdomen and chest. Mixed with figs, and boiled down to
one half, it is administered in wine for dropsy; and it is taken
in a similar manner for pains of the chest, sides, and loins, as
well as for coughs, asthma, and affections of the lungs, liver, and
kidneys, and for shivering fits. Persons about to indulge in
wine, take a decoction of the leaves, to prevent head-ache and
surfeit. Taken in food, too, it is wholesome, whether eaten
raw or boiled, or used as a confection: boiled with hyssop,
and taken with wine, it is good for gripings of the stomach.
Employed in the same way, it arrests internal hæmorrhage,
and, applied to the nostrils, bleeding at the nose: it is beneficial
also to the teeth if rinsed with it. In cases of ear-ache, this
juice is injected into the ears, care being taken to moderate
the dose, as already stated, if wild rue is employed. For
hardness of hearing, too, and singing in the ears, it is similarly
employed in combination with oil of roses, or oil of laurel,
or else cummin and honey.
Juice of rue pounded ill vinegar, is applied also to the
temples and the region of the brain in persons affected with
phrenitis; some persons, however, have added to this mixture
wild thyme and laurel leaves, rubbing the head and neck as
well with the liniment. It has been given in vinegar to
lethargic patients to smell at, and a decoction of it is administered
for epilepsy, in doses of four cyathi, as also just before the
attacks in fever of intolerable chills. It is likewise
given raw to persons for shivering fits Rue is a provocative
9 of
the urine to bleeding even: it promotes the menstrual discharge,
also, and brings away the after-birth, as
well as the dead fœtus even, according to Hippocrates,
10 if
taken in sweet red wine. The same author, also, recommends
applications of it, as well as fumigations, for affections of the
uterus.
For cardiac diseases, Diocles prescribes applications of rue,
in combination with vinegar, honey, and barley-meal: and
for the iliac passion, he says that it should be mixed with
meal, boiled in oil, and spread upon the wool of a sheep's
fleece. Many persons recommend, for purulent expectorations,
two drachmæ of dried rue to one and a half of sulphur; and,
for spitting of blood, a decoction of three sprigs in wine. It is
given also in dysentery, with cheese, the rue being first beaten
up in wine; and it has been prescribed, pounded with bitumen,
as a potion for habitual shortness of breath. For persons suffering
from violent falls, three ounces of the seed is recommended. A pound
of oil, in which rue leaves have been
boiled, added to one sextarius of wine, forms a liniment for
parts of the body which are frost-bitten. If rue really is a
diuretic, as Hippocrates
11 thinks, it is a singular thing that
some persons should give it, as being an anti-diuretic, for the
suppression of incontinence of urine.
Applied topically, with honey and alum, it cures itch-scabs,
and leprous sores; and, in combination with nightshade and
hogs'-lard, or beef-suet, it is good for morphew, warts, scrofula,
and maladies of a similar nature. Used with vinegar and oil,
or else white lead, it is good for erysipelas; and, applied with
vinegar, for carbuncles. Some persons prescribe silphium
also as an ingredient in the liniment; but it is not employed
by them for the cure of the pustules known as epinyctis.
Boiled rue is recommended, also, as a cataplasm for swellings
of the mamillæ, and, combined with wax, for eruptions of
pituitous matter.
12 It is applied with tender sprigs of laurel, in
cases of defluxion of the testes; and it exercises so peculiar an
effect upon those organs, that old rue, it is said, employed in
a liniment, with axle-grease, is a cure for hernia. The
seed pounded, and applied with wax, is remedial also for
broken limbs. The root of this plant, applied topically, is a
cure for effusion of blood in the eyes, and, employed as a liniment,
it removes scars or spots on all parts of the body.
Among the other properties which are attributed to rue, it
is a singular fact, that, though it is universally agreed that it
is hot by nature, a bunch of it, boiled in rose-oil, with the
addition of an ounce of aloes, has the effect of checking the
perspiration in those who rub themselves with it; and that,
used as an aliment, it impedes the generative functions.
Hence it is, that it is so often given in cases of spermatorrhœa,
and where persons are subject to lascivious dreams. Every precaution
should be taken by pregnant women to abstain from
rue as an article of diet, for I find it stated that it is productive
of fatal results to the fœtus.

Of all the plants that are grown, rue is the one that is most
generally employed for the maladies of cattle, whether arising
from difficulty of respiration, or from the stings of noxious
creatures—in which cases it is injected with wine into the
nostrils—or whether they may happen to have swallowed a
horse-leech, under which circumstances it is administered in
vinegar. In all other maladies of cattle, the rue is prepared
just as for man in a similar case.
