"[Plin. Nat. 20.80.] - THE POPPY CALLED TITHYMALON, OR PARALION: THREE REMEDIES.
There is a third kind, again, called “tithymalon;” some persons give it the name of “mecon,” others of “paralion.” It has a white leaf, resembling that of flax, and a head the size of a bean. It is gathered when the vine is in blossom, and dried in the shade. The seed, taken in drink, purges the bowels, the dose being half an acetabulum, in honied wine. The head of every species of poppy, whether green or dry, used as a fomentation, assuages defluxions of the eyes. Opium, if taken in pure wine immediately after the sting of a scorpion, prevents any dangerous results. Some persons, however, attribute this virtue to the black poppy only, the head or leaves being beaten up for the purpose.”

"[Plin. Nat. 26.41.] - THE TITHYMALOS PARALIOS, OR TITHYMALIS: FOUR REMEDIES.
A third kind of tithymalos is known by the additional name of “paralios,” or else as “tithymalis.” The leaf is round, the stem a palm in height, the branches red, and the seed white. This seed is gathered just as the grape is beginning to form, and is dried and pounded; being taken as a purgative, in doses of one acetabulum.”
