Πιτύουσα,
Pityusa; some say that this is a species of spurge, because it has a juice and purges like them.
Commentary. There can be no doubt of its being the Euphorbia Pityusa. It is briefly noticed by all the other writers on the Mat. Med. as possessing the same virtues as the spurges in general.
Πλάτανος,
Platanus, the Plane Tree, is possessed of a humectating and refrigerant power. Hence the green leaves are of use in incipient inflammations. But the bark and spherical balls are more desiccative, so that when one has been boiled in vinegar it relieves toothache. They also cure burns by fire along with fat. The burnt bark is more desiccative and detergent, so as to cure leprosies and humid ulcers.
Commentary. It is the Platanus orientalis, L. The seed forms into spherical balls, which are called Pilulæ by Pliny. He recommends them for the bites of serpents and for burns; also when pounded with acrid vinegar, as a styptic for stopping bleeding. (H. N. xxiv, 29.) Pliny, however, merely copies from Dioscorides, who further recommends the leaves boiled in wine in defluxions of the eyes, and as an application to swellings and inflammations; and its rind boiled in vinegar as a gargle in toothache. (i, 107.) Our author is evidently much indebted to Galen, who commends it for the same medicinal purposes, and warns his readers to guard against the down which grows on its leaves, as it may prove prejudicial to the windpipe, eye, or ear, if admitted into them. (De Simpl. viii.) Aëtius, like our author, copies very closely from Galen. Not much additional information can be drawn from the Arabians, who, under this head, do little more than copy from Dioscorides and Galen. See Avicenna (ii, 2, 209); Serapion (c. 142); Ebn Baithar (ii, 422.)
Πνεύμων,
Pulmo, Lungs; those of lambs and swine are believed to cure the skin which has been chafed by shoes. But the lungs of a fox when dried are said to cure asthmatics. The Pulmo marinus, when fresh and pounded, cures gout and chilblains.
Commentary. Dioscorides, Galen, and Serapion give nearly the same account of the medicinal properties of lungs. The Pulmo marinus is the species of Medusa which bears this scientific name. Our author and all the others follow Dioscorides in defining its medicinal properties. (ii, 39.)
