COMMENTARY. The _Marrubium vulgare_. Dioscorides has an elaborate section on the virtues of this article, which he recommends particularly in phthisical, asthmatic, and catarrhal complaints, as being an excellent expectorant, for promoting the menstrual and lochial discharges, as an alexipharmic, &c. He adds, however, that it is unsuitable in affections of the kidneys and bladder. (iii, 109.) Galen writes thus of it: “Horehound, as it is bitter in taste, so, by general admission, it has the virtue corresponding to that taste, being a deobstruent of the liver and spleen, clearing away matters about the chest and lungs, and promoting menstruation.” He also mentions its use in a cataplasm and in other cases, as stated by Dioscorides. Aëtius and Oribasius state its virtues in nearly the same terms. It is the “Marrubium” of Celsus, who prescribes the juice of it in phthisis (iii, 22), in paralysis (iii, 27), in ulcers of the throat (iv, 4), and for other purposes. For the Arabians, see in particular Serapion (c. 198); Avicenna (ii, 2, 553); Averrhoes (Collig. v, 42.) Avicenna recommends it as deobstruent, emmenagogue, and an application to the eyes. Serapion also praises it as a deobstruent, and recommends it particularly in ulcers of the lungs, asthma, and such like complaints. It would seem to deserve the characters which the ancient authorities give it from Hippocrates down to Macer Floridus and Serapion. See Rutty (Mat. Med. 309.) Even yet it holds a place in the Dispensatory. Πράσον, Porrum, _Leek_, consists of unwholesome juice and is acrid; but Dioscorides says, that it induces disagreeable dreams, agrees well with the bowels, is diuretic and attenuant. It is also detergent, for it proves expectorant when boiled in ptisan. The seed of it is mixed with nephritic remedies. But the leaves have some astringency, and therefore the juice of it proves styptic. * * * * * COMMENTARY. Without doubt it is the _Allium Porrum_, L. Diphilus, as quoted by Athenæus says, “it is attenuant, nutritious, and flatulent.” (Deipnos, ix, 3.) Dioscorides recommends it in the cases enumerated by our author, and also in several others. (ii, 178.) Galen does not treat of it at all in his work on Simples. The Arabians attach more importance to it, recommending it as being emmenagogue, diuretic, aphrodisiac, and so forth. They say of it that it hurts the eyes, the gums, and the teeth. See in particular Avicenna (ii, 2, 540); Rhases (Cont. l. ult. i, 562); Serapion (c. 361); Averrhoes (Collig. v, 42); Ebn Baithar (ii, 339.) Πρίνος, Ilex, _the Holm Oak_, has powers resembling those of the oak, but it is much stronger. * * * * *
