COMMENTARY. From our author’s description there cannot be the least hesitation on our part in acknowledging it to be the _Caryophyllus aromaticus_, L. (_i. q._), _Eugenia Caryophyllata_, Thunberg, that is to say, the Clove-tree. We are equally well convinced that no mention of this article is to be found in the works of Dioscorides, Pliny, Theophrastus, Galen, Aëtius, Oribasius, nor, in short, in those of any preceding author. Whence Paulus drew his knowledge of it cannot now be ascertained. The Arabians display a very correct acquaintance with it. Avicenna, in treating of it, refers to no other Greek authority but Paulus. After describing it in much the same terms as our author, he states it to be hot and dry in the third degree, says it renders the breath fragrant, improves the sight, and is useful in pterygium; is stomachic and hepatic, and removes vomiting and nausea. (ii, 2, 311.) Serapion, in treating of the _Gariofilus_, first quotes from a translation of Galen the description of the _Garyophyllon_ given by Paulus, which he affirms is taken line for line from Galen. This is evidently a mistake, founded on some erroneous translation of Galen into Arabic. He then gives its characters from several Arabian authorities to the effect that it is stomachic, hepatic, cordial, aphrodisiacal, and digestive; and says that it is brought from India. (c. 319.) Rhases says cloves are hot and dry, and are both stomachic and cordial. (Ad Mansor. iii, 22.) We have not been able to find the passage in the ‘Continens’ where they are treated of, there being some mistake in the marginal reference of Avicenna. Symeon Seth says of the caryophyllon that it is hot and dry in the second, or, perhaps, in the third degree; is the fruit of a tree, and is stomachic, hepatic, and cordial; removes nausea connected with humidity, but is bad for the bowels. (c. 15.) The caryophyllon also occurs in one of the antidotes of Myrepsus. (c. 22.) Ebn Baithar, however, is the ancient authority who gives the fullest account of cloves, which he represents as being useful in diabetes and strangury, in black bile, diarrhœa, and chronic coughs. He says in particular that they are uterine and aphrodisiac, and hence warm the uterus and promote impregnation. He also holds that they are stomachic, carminative, and hepatic. (ii, 281.) Κάσσαμον, Cassamum; some say that it is the fruit of the balsam-tree, of which we have treated under that word. Κασσία, Cassia, is heating and desiccative in the third order, consists of sufficiently subtile particles, is acrid, and moderately astringent. It is therefore incisive and discutient, imparts strength to the organs, and is also emmenagogue. * * * * *
