Verbenaca, Vervain, is so desiccative and astringent that it agglutinates wounds, and therefore stops hemorrhage.
Commentary. It is undoubtedly the Verbena officinalis. According to Apuleius, it is styptic, agglutinative, and abstergent. He recommends it as an application to the bites of serpents, phalangia, and mad dogs. Dioscorides, and most of the succeeding authorities down to Macer, recommend it internally for the cure of jaundice, and externally for foul ulcers. He describes two species, of which the second is the Verbena supina. (iv, 60, 61.) Galen describes only one variety, and merely recommends it as being a vulnerary herb. Ebn Baithar’s description of this plant is entirely made up from Dioscorides and Galen. (i, 498.) We are inclined to think that it is the plant described in the translation of Avicenna under the names of Pastus columbarum, s. palea. He recommends it as an application to erysipelas. (ii, 2, 551.) See also Rhases (Cont. l. ult. i, 530.) On its use by the Hindoos, see Ainslie (Mat. Ind. ii, 314.)
Περσαία,
Persica (the Peach?), is an Egyptian tree, the leaves of which are desiccative and astringent, and therefore stop hemorrhage.
Commentary. It has been generally acknowledged as the peach tree, but, as Alston and Woodville state, this supposition is attended with many difficulties. Sprengel is by no means decided; but, upon the whole, inclines to the Cordia Myxa. With this opinion we are not disposed to agree, as we have stated in another place. See under [Myxa]. We would hesitatingly, then, admit it as the Persica vulgaris, Miller. Dioscorides merely recommends the dried powder of the leaves as a good styptic in cases of hemorrhage. Galen and the other Greek authorities give the same character of it. The Arabians, in like manner, follow Dioscorides. See Avicenna (ii, 2, 22.)
Πετασίτης,
Petasites, Butter-burr, is of the third order of desiccants; hence it is used for ill-conditioned and phagedænic ulcers.
Commentary. Dioscorides’s description of this plant with its petasiform leaf, leaves no doubt of its being the Tussilago petasites. He recommends it only for malignant and phagedænic ulcers (iv, 106.) Galen and the other Greek authorities say the same of it. We have not been able to find it in the works of any of the Arabians except Ebn Baithar, who, under this head, merely gives extracts from Dioscorides and Galen. It is still used by the country people as an application to foul ulcers. It was retained in the Dispensatory as late as the time of Quincy.
