COMMENTARY. Our herbalists give the name of Friar’s Cowl to this plant, which even they admit to be possessed of insignificant powers. It is the aris of Pliny. (H. N. xxiv, 16.) Its botanical name is _Arum arisaron_. Dioscorides calls it an acrid medicine, and recommends it solely in collyria. (ii, 198.) The Arabians appear to have confounded it with the arum, under the name of Luf. See Avicenna (ii, 2, 132); and Ebn Baithar (ii, 449.) Ἀριστολοχία, Aristolochia, _Birthwort_; all kinds of it are hot, consist of subtile particles, and are detergent, bitter and subacrid; and are most useful remedies. The round consists of more subtile particles, and is every way more drastic. The clematitis is fragrant but weaker. The long is, in other respects, intermediate between these, but no less hot than the round. * * * * * COMMENTARY. Three species of the Birthwort, the _Aristolochia longa_, _rotunda_, and _clematis_, have been described by the authorities from Dioscorides downwards. The first two still retain their places in our Pharmacopœias, but are seldom used. Dioscorides recommends them, especially as uterine medicines, for promoting menstruation, the lochial discharge, and the expulsion of the fœtus. He also says it is useful in affections of the chest, the spleen, and in other diseases. (iii, 4, 5.) The toxicologists from Nicander downwards recommend the birthwort as an antidote to poisons. See also Theophr. (H. P. ix, 15); and Apuleius (De Herbis.) Mesue describes it as being phlegmagogue, cholagogue, and emmenagogue. He also recommends it in a fumigation along with arsenic for asthma. (De Simpl. ii, 27.) Avicenna treats of it at great length, recommending it strongly as an uterine and alexipharmic medicine. (ii, 2, 49.) See also Rhases (Cont. l. ult. i, 77); Averrhoes (Collig. v, 42); Serapion (c. 171); Ebn Baithar, _pluries_. Pliny describes a fourth species under the name of Pistolochia. Modern authorities confirm the birthwort’s character as to its being powerfully emmenagogue. See Quincy, Lewis, Pereira, and the other writers on the Materia Medica. Ἄρκευθος, Juniperus, _the Juniper_, heats and dries in the third degree. The fruit is equally calefacient, but desiccant only in the first degree. * * * * *
