COMMENTARY. The two species of savine described by Dioscorides are probably the _Sabina cypressifolia_ and _tamariscifolia_. He recommends it principally as an external application to spreading sores and carbuncles. He says it produces bloody water and abortion when drunk in wine, and when applied externally, or in the form of fumigation. (i, 104.) All the ancient authorities, including Macer Floridus (but his works, we are well aware, are not generally reputed genuine), hold it to be an uterine medicine. Its medicinal and deleterious powers are given in like manner by the Arabians. See in particular Avicenna (ii, 2, 6); Serapion (c. 255); Ebn Baithar (i, 5.) Apuleius praises it strongly in jaundice. We need scarcely mention that savin still retains its place in our Dispensatory, being, according to Pereira, “the most certain and powerful emmenagogue of the whole Materia Medica.” With regard to its action on the animal economy, “it operates,” according to Sundelin, as quoted by Pereira, “as a specific excitant and irritant on the kidneys, and yet more obviously on the uterus.” All this shows how correctly the ancient authorities had judged of its powers. Βρεττανίκη, Bretannica, _Water-dock_, is possessed of astringent and agglutinative powers, and in appearance resembles the Wild-dock. The juice of it cures mortifications in the mouth. * * * * * COMMENTARY. It would not be worth while, even if this were the proper place, to touch upon the lengthened controversy which has prevailed among the old herbalists and botanical authorities with regard to this plant. Whoever would wish to investigate the subject may consult Professor Munting’s elaborate work ‘De Vera Herba Britannica,’ (Amst. 1698,) and Sprengel’s ‘Annotations on Dioscorides’ (iv, 2.) Suffice it to say, that, in all probability, the plant in question was some species of water-dock. All the authorities who treat of it give it much the same character as our author. See particularly Avicenna (ii, 2, 102); Serapion (c. 222.) It held a place in our English Dispensatory as late as Quincy, who represents it (“the hydrolopathum, supposed to be the Bretannica of the ancients”) as a specific for scurvy. Βρόμος, Avena, _Oats_, has powers resembling those of barley. It is desiccative, and moderately discutient without pungency. It has also some astringency, whence it cures diarrhœas. * * * * * COMMENTARY. It is not well ascertained whether this be an _Avena_ or _Secale_. The chapter of Dioscorides under this head is probably spurious. Our author abridges Galen. It is not treated of by Celsus nor the Arabians. Βρύον, Bryum; the sea-bryum or lichen is cooling and astringent, and is therefore useful when applied as a cataplasm to hot inflammations; that kind which is called splanchnon, being found on oaks, white poplars, and pitch-trees, is at the same time discutient and moderately emollient, more especially that upon cedars.
