"[Plin. Nat. 20.9.] - RAPE: NINE REMEDIES.
Rape, too, has its medicinal properties. Warmed, it is used as an application for the cure of chilblains, in addition to which, it has the effect of protecting the feet from cold. A hot decoction of rape is employed for the cure of cold gout; and raw rape, beaten up with salt, is good for all maladies of the feet. Rape-seed, used as a liniment, and taken in drink, with wine, is said to have a salutary effect against the stings of serpents, and various narcotic poisons; and there are many persons who attribute to it the properties of an antidote, when taken with wine and oil.
Democritus has entirely repudiated the use of rape as an article of food, in consequence of the flatulence which it produces; while Diocles, on the other hand, has greatly extolled it, and has even gone so far as to say that it acts as an aphrodisiac. Dionysius, too, says the same of rape, and more particularly if it is seasoned with rocket; he adds, also, that roasted, and then applied with grease, it is excellent for pains in the joints."

"[Plin. Nat. 20.10.] - WILD RAPE: ONE REMEDY.
Wild rape is mostly found growing in the fields; it has a tufted top, with a white seed, twice as large as that of the poppy. This plant is often employed for smoothing the skin of the face and the body generally, meal of fitches,1342 barley, wheat, and lupines, being mixed with it in equal proportions.
The root of the wild rape is applied to no useful purpose whatever."

"[Plin. Nat. 20.11.] - TURNIPS: THOSE KNOWN AS BUNION AND BUNIAS: FIVE REMEDIES.
The Greeks distinguish two kinds of turnips, also, as employed in medicine. The turnip with angular stalks and a flower like that of anise, and known by them as “bunion,” is good for promoting the menstrual discharge in females and for affections of the bladder; it acts, also, as a diuretic. For these purposes, a decoction of it is taken with hydromel, or else one drachma of the juice of the plant. The seed, parched, and then beaten up, and taken in warm water, in doses of four cyathi, is a good remedy for dysentery; it will stop the passage of the urine, however, if linseed is not taken with it.
The other kind of turnip is known by the name of “bunias,” and bears a considerable resemblance to the radish and the rape united, the seed of it enjoying the reputation of being a remedy for poisons; hence it is that we find it employed in antidotes."
