Crocus, Saffron, is of the second order of heating and of the first of desiccative medicines. It is also astringent and digestive.

Commentary. Without doubt it is the Crocus sativus. Dioscorides gives an interesting account of the different varieties of it which were used in his time. Suffice it to say, that the best decidedly was the Cicilian, from Mount Corycus, which is often alluded to by classical authors. See Pliny (xxi, 6); Celsus (v, 22); Statius (Silv. v, 3, 41); Galen (De Antid. i.) With regard to its action on the animal economy, he mentions that Thessalus held that it is merely fragrant, while some, on the other hand, maintained that it is a deadly poison in doses of dr. iij, but that in truth it is diuretic and sub-astringent, and therefore applicable to erysipelas and defluxions of the eyes, as a cure for surfeit, and for producing a discharge of urine (i, 25.) See, in like manner, Pliny (l. c.) It occurs in the Hippocratic treatises, and in the works of Celsus, who calls it purgative, emollient, and discutient. (196.) By the way, we may mention that by purgative, Celsus evidently means cleansing in external applications, as is evident from the substances with which it is enumerated, namely, verdigris, orpiment, &c. His editor, Dr. Milligan, therefore evidently mistakes the meaning of his author. (l. c.) Galen and his followers call it heating in the second degree, and drying in the first, with some astringency. The Arabians adopt the views of the Greeks as to its virtues, but prescribe it in a great many more cases than their predecessors. See Serapion (c. 173); Rhases (Cont. l. ult. i, 241); Avicenna (ii, 2, 126.) Thus they held that it is both aphrodisiacal and cordial, and recommend it accordingly. They also used it in cases of difficult labour, and as a deobstruent in obstructions of the liver and spleen. One of Rhases’s authorities says that in doses of three drachms it proves fatal. Another of them says of it, that it improves the breathing and appetite. Symeon Seth says that it is stomachic and improves the colour. He, Serapion, and other of the ancient authorities, affirm that in large doses it occasions involuntary laughter, immoderate mirth, and the other effects which result from intoxicating liquors. From late experiments, it would appear that its powers had been overrated. See Pereira (Mat. Med. 696.) It was much used by the ancients as a perfume. See Beckmann’s ‘Hist. of Inventions,’ Joh. Bodæus a Stapel (Ad Theophrast. H. P. vi, 6), and Hertodt’s ‘Crocologia,’ as quoted by him. Its medical use, he adds, has always continued among the Orientals.

Κρόμμυον,

Cepa, Onion, is of the fourth order of heating medicines, its substance consisting of thick matter, and hence when applied to hemorrhoids it opens them. It is also sufficiently detergent, and removes alphos with vinegar; and in alopecia it occasions a more rapid growth of hair than alcyonium. Its juice is useful in suffusion and dimness of vision from thick humours.

Commentary. It is the Allium Cepa, or onion. Galen, Dioscorides, and Serapion recommend it as an application in cases of alopecia or Porrigo decalvans. Dioscorides says that some applied it as a suppository to promote the discharge of blind piles, and he mentions its being introduced into the nose to promote the discharge from it. As a cataplasm with salt, rue, and honey, he recommends it for the bites of rabid dogs. He says it concocts and breaks hard tumours. Upon the whole, Galen, Aëtius, Oribasius, and our author, do little more under this head than abridge the more ample account of it given by Dioscorides. Celsus calls it an aperient of the bowels (ii, 29) and a diuretic (ii, 31.) He recommends it to be chewed in paralysis of the tongue. (iv, 2.) The Arabians treat of it at great length. See Avicenna (ii, 2, 119); Rhases (Cont. l. ult. iii, 18); Serapion (c. 354.) They speak favorably of it as a rubefacient, and all ascribe great powers to it as an alexipharmical medicine.

Κύαμος,

Faba, the Bean, is not far removed from a middle temperament as to cooling and drying. Its flesh is also somewhat detergent. It agrees, therefore, with expectorations from the chest and lungs. Its outer skin having also some astringency renders the whole bean, when boiled in oxycrate, a suitable remedy for cæliac and dysenteric affections. In a cataplasm it cures inflammations and swellings, and dispels the milk in the breasts.

Commentary. We have stated in the [First Book] the difficulty of determining exactly the nature of the ancient faba. See Parkinson (Theatre of Plants, 1054) and Dickson (Husbandry of the Ancients.) Dioscorides describes two species, the Egyptian and the Greek, of which the former, there can be little doubt, is the Nelumbium speciosum. See Sprengel (Ad Dioscor. ii, 128), and Lindley (Veget. King. 414.) The other, as we formerly stated, was probably a variety of our small bean. The characters of both are fully stated by Dioscorides, from whom Galen and our author borrow largely under this head. They treat, however, only of the Greek bean. Dioscorides says the Egyptian is astringent and stomachic; that the flour of it made into a poultice, answers in dysenteric and colic affections, and in earache. The Arabians give a very full account of the two species of bean, both as articles of food and as medicines. See in particular, Avicenna (ii, 2, 241); Serapion (c. 97); Rhases (Cont. l. ult. i, 279.) Avicenna and Rhases agree in commending beans for spitting of blood, and other affections of the chest.

Κύανος,

Cyanus, is possessed of acrid, purgative, and discutient powers, greater than those of the cinnabar. It has also some astringency.
