"[Plin. Nat. 27.79.] - THE MEDION: TREE REMEDIES.
The medion has leaves like those of the cultivated seris, a stem three feet in length, and a large, round, purple flower, at its extremity. The seed is diminutive, and the root half a foot in length: it grows upon umbrageous, sheltered rocks. The root, taken in doses of two drachmæ with honey, arrests the catamenia, the electuary being used for some days. The seed, too, is administered in wine for a similar purpose."
