"[Plin. Nat. 20.37.] - THE LAPSANA: ONE REMEDY.
Among the wild cabbages, we find also the lapsana, a plant which grows a foot in height, has a hairy leaf, and strongly resembles mustard, were it not that the blossom is whiter. It is eaten cooked, and has the property of soothing and gently relaxing the bowels.”
