Galla, Gall; that sort called Omphacitis is a very sour medicine, and hence it proves desiccant, repels defluxions, contracts and astringes relaxed and debilitated parts. It agrees also with all cases of defluxion. It is to be placed in the third rank of desiccants, and the second of refrigerants. The other sort, which is yellow, porous, and large, is desiccant indeed, but less so than the other, inasmuch as it is deficient in astringency. In a decoction it relieves inflammations of the fundament and prolapsus ani when burnt. Extinguished in vinegar they become styptic.
Commentary. Dioscorides describes two species of galls, of which the better kind, called omphacitis, consisted of small, hard, and solid pieces without perforations, and is not to be confounded with the ὄμφακις, or cupula of the acorn, mentioned by Paulus. (iii, 62.) See also Theophrastus (Hist. Plant. iii, 9), Pliny (H. N. xvi, 9), and Serapion (De Simpl. c. 237.) Galls were much used by the ancient physicians in all cases requiring powerful astringents. According to Dr. Hill, the Gallæ omphacitæ of the ancients were the same as the Aleppo galls now in use, and the other kind, sometimes called Onocicæ, the same as the European. Dioscorides describes the gall as the fruit of the oak, an error which is to be found, as Dr. Pereira remarks, in the works of comparatively recent writers. We need scarcely say that the excrescence is now well ascertained to be the production of a hymenopterous insect on the Quercus infectoria. Dioscorides treats largely of the cases in which galls are applicable, concluding with the remark that their use is indicated whenever it is wished to astringe, restrain, or dry. (ii, 146.) Our author’s description of their medicinal properties is mostly taken from Galen. Nearly the same may be said of Aëtius and Oribasius. The Arabians, in treating of them, borrow all the information which they give from the Greeks. See in particular Avicenna (ii, 2, 308), Rhases (Cont. l. ult. i, 234), Serapion (c. 98.)
Κηπέα,
Cepea, resembles the Purslain. The leaves of it in an infusion relieve scabious bladder when drunk; and the root of it, when taken in a draught with rock asparagus, relieves strangury from obstruction.
Commentary. Little is known for certain of this herb; but the most probable conjecture that has been made regarding it is, that it is the Sedum Cepæa, L. Our author’s account of it is taken literally from Dioscorides. Galen does not treat of it, nor have we been able to trace it out in the Materia Medica of the Arabians. Our old herbalists treat of it very hesitatingly under the head of brooklime. See Gerard and Parkinson.
Κηρὸς,
Cera, Wax, being of a moderate temperament, forms the basis of many other medicines. By itself it is slightly detergent, and has some discutient and calefacient powers.
Commentary. This article is so well known that it requires no illustration. Dioscorides describes very circumstantially the process for bleaching wax and making it white. It was done with salt water and natron in a manner quite different from the process now pursued for this purpose. (ii, 105.) The Arabians treat fully of it, but without making any addition of much importance. See in particular Serapion (c. 10) and Avicenna (ii, 2, 462.) Avicenna says that wax, when applied to the wound inflicted by a poisoned arrow, prevents it from being followed by any bad effects. He recommends it as an expectorant in diseases of the chest, both in a liniment and in a potion. One of Serapion’s authorities, Abugerig, in like manner, recommends it in diseases of the chest.
Κήρυκες,
Buccinæ (a species of shell-fish); their shell when burnt is possessed of sufficiently desiccative powers without pungency, they therefore agree with malignant ulcers, and are to be used for putrid ulcers with vinegar, wine, or oxymel. That part of them which is as it were their flesh when alive, if boiled in oil, renders the oil an useful injection for relieving earache.
