Commentary. It appears from Dioscorides that the Lime used by the ancient physicians, was prepared by calcination from shells, pebbles, or marble, which last is the best of all. Pliny, Vitruvius, and Palladius say, that the best lime is got from hard, white stone. Lime was much used as a caustic and stimulant application. The Ἄσβεστος of the Greek Mat. Med. invariably, we believe, signifies quicklime, and is never applied to the mineral which now bears that name. Dioscorides says, all kinds of quicklime have a fiery, biting, caustic, and escharotic power; when mixed with other things as suet or oil, it becomes digestive, emollient, depilatory, and epulotic; and that which is recent and free from water is more efficacious. (v, 132.) Pliny recommends it in the same cases, and also as an application to luxations and strumæ. (H. N. xxxvi, 57.) See also Plinius Valerianus (iii, 20.) Celsus places it in his list of corrosive and caustic substances. (v, 6, 8.) Our author’s account of this article is condensed from Galen. Aëtius and Oribasius give nearly the same account of it as Dioscorides and Galen. Quicklime was used as a medicine in the Hippocratic age. (See Erotianus.) For the Arabians, consult Avicenna (ii, 2, 144); Rhases (Cont. l. ult. iii, 20, i, 445); Serapion (De Simpl. 412); Haly Abbas (Pract. ii, 44); Averrhoes (Collig. v, 43); Ebn Baithar (ii, 387.) All these authorities, including even the last, who is by far the most original of their writers on the Mat. Med., borrow under this head almost all their information from Dioscorides and Galen. Avicenna praises it as an application to burns.
Τραγακάνθα,
Tragacantha, Tragacanth, has similar powers to gum.
Commentary. The ancient Tragacanth was identical with the modern, which is yielded by Astragalus verus, and similar spiny species. See Lindley (Veg. King. 548.) According to Sibthorp, the Astragalus aristatus is the one which most commonly grows in the Peleponnesus, and he holds that it produces the T. of Dioscorides. (Prod. Fl. Græc. ii, 90.) Dioscorides, like our author, states, that in virtue it resembles gum, and recommends it in ophthalmic remedies, for roughness of the windpipe, loss of speech, and epistaxis, in a linctus with honey. He also recommends it when allowed to melt below the tongue, for pain of the kidneys and bladder, when mixed with hartshorn burnt and washed, and a little fissile alum. (iii, 20.) Galen and the other Greek authorities state its virtues in very general terms. It is an ingredient in more than one of the collyria of Celsus (vi, 6), and is prescribed by him for various other purposes. Of the Arabians, Ebn Baithar is the one who gives the fullest account of it. (ii, 350.) See also Avicenna (ii, 2, 220.) In the modern Greek Pharmacopœia the Astragalus aristatus is described as producing the tragacanth. It is there said to be common in the Peleponnesus.
Τράγιον,
Tragium, Stinking St. John’s Wort, is a plant in Crete resembling the lentisk, being hot in the third degree, and possessed of attractive, discutient, and attenuant powers. It extracts sharp-pointed weapons of wood, and proves lithontriptic and emmenagogue when drunk to the amount of a drachm. Another species, which is bitterer than this, resembling the ceterach, grows everywhere. It is sufficiently astringent so as to agree with fluxes.
Commentary. From the description which Dioscorides gives of the former species, we need have little hesitation in setting it down for the Hypericum hircinum. In the other, the name Tragium Columnæ has been assigned from the name of a celebrated botanist. Dioscorides and Galen ascribe to it very nearly the same virtues as our author. Neither of these plants occurs in the works of Hippocrates or Celsus. Neither have we been successful in searching for it in the works of the Arabians, with the exception of those of Ebn Baithar, who merely gives extracts from Dioscorides and Galen under this head. (ii, 155.)
Τραγορίγανος,
Tragoriganon, has powers resembling marjoram, with the addition of some astringency.
