After all, however, the Greek writers are by no means agreed as to this plant; some say, for instance, that it has leaves like those of rocket, while others maintain that they resemble those of the robur, only that they are considerably smaller. Some, again, assert that the root is useless, while others aver that it is beneficial for the sinews, and others that it produces suffocation, if taken in drink. On the other hand, some have prescribed it in wine, for jaundice and all affections of the bladder, heart, and liver, and give it as their opinion that it carries off gravel from the kidneys. It has been prescribed, also, by them for sciatica, the patient taking one drachma in oxymel, after a walk; and has been recommended as extremely useful for griping pains in the bowels, taken in raisin wine. They assert, also, that used as an aliment with vinegar, it is wholesome for the thoracic organs, and recommend it to be grown in the garden for these several purposes. In addition to this, there are some authorities to be found, which distinguish another variety of this plant, but without mentioning its peculiar characteristics. This last they recommend to be taken in water, to neutralize the venom of serpents, and prescribe it to be eaten for the cure of epilepsy. For my own part, however, I shall only speak of it in accordance with the uses made of it among us Romans, uses based upon the results of actual experience. The down of this plant, beaten up with saffron and a little cold water, is applied to defluxions of the eyes; parched with a little salt, it is employed for the cure of scrofulous sores. CHAP. 107.—THE EPHEMERON: TWO REMEDIES. The ephemeron[930] has leaves like those of the lily, but smaller; a stem of the same height, a blue flower, and a seed of which no use is made. The root is single, about the thickness of one’s finger, and an excellent remedy for diseases of the teeth; for which purpose it is cut up in pieces, and boiled in vinegar, the decoction being used warm as a collutory. The root, too, is employed by itself to strengthen the teeth, being inserted for the purpose in those that are hollow or carious. Root of chelidonia[931] is also beaten up with vinegar, and kept in the mouth. Black hellebore is sometimes inserted in carious teeth; and a decoction of either of these last-mentioned plants, in vinegar, has the effect of strengthening loose teeth. CHAP. 108.—THE LABRUM VENEREUM: ONE REMEDY. Labrum Venereum[932] is the name given to a plant that grows in running streams.[933] It produces a small worm,[934] which is crushed by being rubbed upon the teeth, or else enclosed in wax and inserted in the hollow of the tooth. Care must be taken, however, that the plant, when pulled up, does not touch the ground. CHAP. 109.—THE BATRACHION, RANUNCULUS, OR STRUMUS; FOUR VARIETIES OF IT: FOURTEEN REMEDIES.
