Commentary. Dioscorides says of the Daucus gingidium, that it is a good potherb, and that as a medicine, when taken in a decoction with wine, it is diuretic and lithontriptic. (ii, 166.) Galen defines its virtues to be considerable astringency with slightly heating powers. The others treat of it in like terms. Few if any of the Arabians have noticed it.
Γλαύκιον,
Glaucium, Horned Poppy, is rather disagreeably astringent, but decidedly refrigerant, so that it cures erysipelas when the attack is not severe.
Commentary. In the [Fifth Book] we have treated of the different species of poppy used by the ancients. It appears from Dioscorides that it was its expressed juice which was used in practice. It was used principally in applications to the eyes. Our author borrows from Galen, and he follows Dioscorides (iii, 90.) The Arabians recommend it, not only in affections of the eyes, but also in boils and erysipelas. See particularly Avicenna (ii, 2, 470); Rhases (Cont. l. ult. i, 464.) As far as we can discover, it does not occur in the works of the Hippocratists, nor in those of Celsus. It has been scarcely known in the modern practice of medicine.
Γλαὺξ,
Glaux, Milkwort; the herb is hot and humid in temperament, and, therefore, promotes the formation of milk.
Commentary. Dioscorides gives a very circumstantial description of it, from which it has been concluded that the Glaux was a species of Astragalus. (iv, 139.) All the authorities mention it in the same light as our author, but few of them have described it. We are not aware of its having been used in modern practice.
Γλήχων,
Pulegium, Pennyroyal, is strongly calefacient and attenuant. Hence, when applied externally, it proves rubefacient. It also promotes the expectoration of thick and viscid humours lodged in the chest and lungs.
Commentary. Dioscorides commends the Mentha Pulegium as an emmenagogue, and for forwarding delivery; and the same character has descended to it down to recent times. See Gerard, Culpeper, Quincy, and Hill. Even at the present day it holds a place in our Dispensatories, but with a diminished reputation: stat magni nominis umbra! The Arabians generally treated of it along with the dittany. See Avicenna (ii, 2, 461); Serapion (De Simpl. 310.)
