"[Plin. Nat. 27.57.] - GALEOPSIS, GALEOBDOLON, OR GALION: SIX REMEDIES.
Galeopsis, or as some call it, "galeobdolon" or "galion," is a plant with a stem and leaves like those of the nettle, only smaller; and which, when bruised, emit a powerful smell. The flower is purple, and the plant is found growing everywhere, about hedges and foot-paths. The leaves and stems, bruised in vinegar, and applied topically, are curative of indurations, carcinomata, and scrofulous sores. They disperse also inflam- natory tumours and imposthumes of the parotid glands, and it is found a useful plan to foment the parts affected with a decoction of them. Applied with salt, this plant is curative of putrid ulcers and gangrenous sores. "
