The seed of rocket[1528] is remedial for the venom of the scorpion and the shrew-mouse: it repels, too, all parasitical insects which breed on the human body, and applied to the face, as a liniment, with honey, removes[1529] spots upon the skin. Used with vinegar, too, it is a cure for freckles; and mixed with ox-gall it restores the livid marks left by wounds to their natural colour. It is said that if this plant is taken in wine by persons who are about to undergo a flogging, it will impart a certain degree of insensibility to the body. So agreeable is its flavour as a savouring for food, that the Greeks have given it the name of “euzomon.”[1530] It is generally thought that rocket, lightly bruised, and employed as a fomentation for the eyes, will restore the sight to its original goodness, and that it allays coughs in young infants. The root of it, boiled in water, has the property of extracting the splinters of broken bones.
As to the properties of rocket as an aphrodisiac, we have mentioned them already.[1531] Three leaves of wild rocket plucked with the left hand, beaten up in hydromel, and then taken in drink, are productive of a similar effect.
CHAP. 50.—NASTURTIUM: FORTY-TWO REMEDIES.
Nasturtium,[1532] on the other hand, is an antiaphrodisiac;[1533] it has the effect also of sharpening the senses, as already stated.[1534] There are two[1535] varieties of this plant: one of them is purgative, and, taken in doses of one denarius to seven of water, carries off the bilious secretions. Applied as a liniment to scrofulous sores, with bean-meal, and then covered with a cabbage-leaf, it is a most excellent remedy. The other kind, which is darker than the first, has the effect of carrying off vicious humours of the head, and sharpening the sight: taken in vinegar it calms the troubled spirits, and, drunk with wine or taken in a fig, it is good for affections of the spleen; taken in honey, too, fasting daily, it is good for a cough. The seed of it, taken in wine, expels all kinds of intestinal worms, and with the addition of wild mint, it acts more efficaciously still. It is good, too, for asthma and cough, in combination with wild marjoram and sweet wine; and a decoction of it in goats’ milk is used for pains in the chest. Mixed with pitch it disperses tumours, and extracts thorns from the body; and, employed as a liniment, with vinegar, it removes spots upon the body. When used for the cure of carcinoma, white of eggs is added to it. With vinegar it is employed also as a liniment for affections of the spleen, and with honey it is found to be very useful for the complaints of infants.
Sextius adds, that the smell of burnt nasturtium drives away serpents, neutralizes the venom of scorpions, and gives relief in head-ache; with the addition too, of mustard, he says, it is a cure for alopecy, and applied to the ears with a fig, it is a remedy for hardness of hearing. The juice of it, he says, if injected into the ears, will effect the cure of tooth-ache, and employed with goose-grease it is a remedy for porrigo and ulcerous sores of the head. Applied with leaven it brings boils[1536] to a head, and makes carbuncles suppurate and break: used with honey, too, it is good for cleansing phagedænic ulcers. Topical applications are made of it, combined with vinegar and polenta, in cases of sciatica and lumbago: it is similarly employed, too, for lichens and malformed[1537] nails, its qualities being naturally caustic. The best nasturtium of all is that of Babylonia; the wild[1538] variety possesses the same qualities as the cultivated in every respect, but in a more powerful degree.
CHAP. 51.—RUE: EIGHTY-FOUR REMEDIES.
One of the most active, however, of all the medicinal plants, is rue.[1539] 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,[1540] and that of Macedonia more particularly, which grows on the banks of the river Aliacmon.[1541] 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[1542] 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’sbane[1543] 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,[1544] 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,[1545] 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 topically, 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,[1546] the rue should be applied with barley-meal and vinegar. 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 in 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[1547] 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,[1548] if taken in sweet red wine. The same author, also, recommends applications of it, as well as fumigations, for affections of the uterus.
