We have already[198] enumerated some twenty varieties of the ivy. The medicinal properties of them all are of a doubtful nature; taken in considerable quantities they disturb the mental faculties and purge the brain. Taken internally they are injurious to the sinews,[199] but applied topically they are beneficial to those parts of the body. Ivy possesses properties similar[200] to those of vinegar. All the varieties of the ivy are of a refrigerative nature, and taken in drink they are diuretic. The softer leaves, applied to the head, allay head-ache, acting more particularly upon the brain and the membrane which envelopes that organ. For this purpose the leaves are bruised with vinegar and oil of roses and then boiled, after which some more rose-oil is added. The leaves too are applied to the forehead and the mouth is fomented with a decoction of them, with which the head is rubbed as well. They are useful also for the spleen, the leaves being applied topically, or an infusion of them taken in drink. A decoction of them is used for cold shiverings in fevers, and for pituitous eruptions; or else they are beaten up in wine for the purpose. The umbels too taken in drink or applied externally, are good for affections of the spleen, and an application of them is useful for the liver; employed as a pessary, they act as an emmenagogue. The juice of the ivy, the white cultivated kind more particularly, cures diseases of the nostrils and removes habitually offensive smells. Injected into the nostrils it purges the head, and with the addition of nitre it is still more efficacious for that purpose. In combination with oil, the juice is injected for suppurations or pains in the ears. It is a corrective also of the deformities of scars. The juice of white ivy, heated with the aid of iron, is still more efficacious for affections of the spleen; it will be found sufficient, however, to take six of the berries in two cyathi of wine. Three berries of the white ivy, taken in oxymel, expel tape-worm, and in the treatment of such cases it is a good plan to apply them to the abdomen as well. Erasistratus prescribes twenty of the golden-coloured berries of the ivy which we have mentioned as the “chrysocarpos,”[201] to be beaten up in one sextarius of wine, and he says that if three cyathi of this preparation are taken for dropsy, it will carry off by urine the water that has been secreted beneath the skin. For cases of tooth-ache he recommends five berries of the chrysocarpos to be beaten up in oil of roses, and warmed in a pomegranate-rind, and then injected into the ear opposite the side affected. The berries which yield a juice of a saffron, colour, taken beforehand in drink, are a preservative against crapulence; they are curative also of spitting of blood and of griping pains in the bowels. The whiter umbels of the black ivy, taken in drink, are productive of sterility, in males even. A decoction in wine
