Onosma, or Onomis, Stone Bugloss (called also Phlomitis or Ononis), is acrid and bitter, and hence the leaves of it when drunk with wine kill and expel the fœtus.
Commentary. That it was a species of Anchusa, or one of its congeners, is obvious, from the description of it given by Dioscorides, who says, the stalk, the fruit, and the flower, are very like to the anchusa. It seems probable, then, that it was some species either of Anchusa or Lithospermum. The Onosma of Linnæus, as Sprengel justly remarks (Ad Dioscor. iii, 137), is altogether a plant of a different character. Dioscorides, like our author, says it has great powers in procuring abortion; nay, that it was alleged that if a pregnant woman walked upon the plant she would miscarry. (l. c.) It is said that Aretæus recommends it in nephritic complaints. Pseudo-Dioscor. (Euporist. ii, 112.) Galen and the other authorities who notice it, do so in nearly the same language as our author. We have not been able to discover any traces of it in the works of the Arabians.
Ὀνόβρυχις,
Onobrychis, Cockshead, is possessed of aromatic and discutient powers. It therefore discusses phymata, cures strangury, and proves sudorific.
Commentary. Dioscorides describes it as having leaves like the lentil, or a little longer, a stalk a fathom long, a purple flower, and small root, and grows in wet and uncultivated grounds. This description seems clearly to point to the Onobrychis sativa, a plant of the tribe Fabaceæ. Dioscorides holds it to be diuretic and sudorific, and discussive of tumours. (iii, 160.) It appears to have been generally used as a diuretic. Pseudo-Dioscor. (Euporist. ii, iii.) Galen gives exactly the same account of it as our author; indeed, both borrow from Dioscorides. The Arabians would appear to have rejected it from their Mat. Med. Although it has long ceased to occupy a place in the Dispensatory, the sainfoin, or cockshead, is still known to the vendors of medicines, and retains its ancient characters of being “ripening, discussive, useful in strangury.” Gray (Pharmacop. 96.) Our old herbalist, Culpeper, ascribes to it the same virtues. (Complete Herbal, 52.)
Ὄνοι,
Aselli, Millepedes, or Slaters; those found under water-vessels, which roll themselves into a ball when touched, are possessed of discutient and desiccative powers. Therefore, when drunk with wine they cure dysuria and jaundice, and in cases of cynanche they are rubbed in with honey: and for earache they are triturated with rose oil, and being warmed in the shell of a pomegranate are injected into the ear.
Commentary. The Millepedes are thus described by Marcellus Empiricus: “In locis humidis et sordidis sub lapidibus inveniuntur bestioliæ multipedes quæ contactæ contrahuntur et rotundantur.” (De Medicamentis, c. xxxv.) They are the Porceliones of Cælius Aurelianus (i, 4), who calls them “animalia quæ humectis et aquosis locis sæpe nascuntur, a Græcis appellata onisci.” (Tard. Pass.) Almost all the ancient authorities on the Materia Medica from Dioscorides downwards, recommend them in the same cases as our author does. In fact, almost all the authorities take the characters of the millepedes from Dioscorides. (ii, 37.) See in particular Serapion (De Simpl. 4, 29), Avicenna (ii, 2, 718.) They particularly commend the use of them in jaundice. In English they are called Slaters or Cheslops. They held a place in the Edinburgh Dispensatory until after the edition of it in 1811. In fact, the highest modern authorities testify to the medicinal virtues ascribed to them by the ancient authorities. Moses Charras, who makes frequent mention of them, says, that a volatile salt is obtained from them which is highly diaphoretic. Dr. Hill calls them aperient, attenuant, and detergent. Dr. Mead recommends them strongly for their diuretic property. He directs us to put them into wine, and afterwards to strain off the liquor, and sweeten it with honey or sugar. (Monita et præcepta.) It would appear that they are still used in France as diuretics. In Dr. Pemberton’s edition of the London Dispensatory, 1746, it is directed to inclose them in a thin canvass cloth, and suspend them within a covered vessel over the steam of hot spirit of wine, by which they will be killed and rendered friable. Lister calls them lithontriptic.
Ὂνυχες,
Onyches, are the covers of Indian shell-fishes. These, in a fumigation, rouse those affected with uterine suffocation and epileptics. But when drunk they disorder the belly.
