Commentary. The ancient descriptions of this plant seem to point to the burdock, which, however, owing to a confusion of names, has been called the Arctium lappa. Dioscorides recommends it internally in diseases of the chest, and externally as a cataplasm to old ulcers. (iv, 105.) This is the same as the second arctium of Galen, who recommends it in the same cases as Dioscorides. Apuleius, like Dioscorides, says it is useful in cases of strangury. Our old herbalists treat of the virtues of the burdock in the same terms as the Greek and Roman authorities. The Arabians, as far as we can discover, do not treat either of the arcion or the arction, with the exception of Ebn Baithar, who merely gives extracts from Dioscorides and Galen, and seems puzzled to distinguish the two plants from one another. (i, 25.) In the modern Greek Dispensatory both the Arctium bardana and the A. lappa are set down as corresponding to the ἄρκειον.

Ἄρκτιον,

Arctium, Lappa, is like the verbascum; its roots are tender, white, and sweet: it consists of subtile particles, and is possessed of desiccant and moderately detergent powers.

Commentary. This, which is treated of under the same name by Dioscorides (iii, 104), and is the former arctium of Galen, is probably the Verbascum sanguineum. The description of it given by Galen, at all events, points to some species of the mullein. Both the authorities we have mentioned recommend it as an application to burns and chilblains.

Ἀρμενιακὸν,

Armeniacum, has detergent properties with a little acrimony, and a small degree of astringency. It is therefore mixed up with ophthalmic medicines, and promotes the growth of the hairs of the eyelids.

Commentary. We shall not enter into the discussion of disputed points respecting this article, further than to state our own opinion, that in all probability it was a native ore of carbonate of copper; but which of the species or sub-species described by modern mineralists the armenium was, we cannot venture to decide. See Cleavland’s Mineralogy (p. 570, &c.) Dioscorides, who treats of it under the name of armenium, (v, 105), compares it to chrysocolla, which it is well ascertained is that species of native carbonate of copper now described under the names of copper green and mountain green. He merely recommends it as a cosmetic when applied to the eyelashes. Serapion confounds this substance with the Lapis armeniacus, (c. 404); but Avicenna accurately distinguishes between them. (ii, 2, 56, 415.)

Ἀρνάβω,

Arnabo, is one of the aromatics. Hence it is mostly mixed up with ointments, being possessed of hot and dry powers in the third degree, like cassia and carpesium. Hence Posidonius says, that it may be used instead of cinnamon when it is not at hand.

Commentary. This article, which is treated of only by Aëtius (xvi, 113), besides our author, has never been accurately determined. It has been supposed to be the zerumbeth, of which we will have occasion to treat more fully in another place. See the [Appendix].
