"[Plin. Nat. 24.98.] - THE ONOBRYCHIS: THREE REMEDIES.
The onobrychis has leaves like those of the lentil, only somewhat longer; the blossom is red, and the root small and slender. It is found growing in the vicinity of springs. Dried and reduced to powder, and sprinkled in white wine, it is curative of strangury, and arrests looseness of the bowels. The juice of it, used as a friction with oil, acts as a sudorific.”
