"[Plin. Nat. 24.49.] - THE CISSOS ERYTHRANOS: TWO REMEDIES. THE CHAMÆCISSOS: TWO REMEDIES. THE SMILAX: THREE REMEDIES. THE CLEMATIS: EIGHTEEN REMEDIES.
The plant called “cissos erythranos” by the Greeks, is similar to the ivy: taken in wine, it is good for sciatica and lumbago. The berries, it is said, are of so powerful a nature as to produce bloody urine. “Chamæcissos” also is a name given by them to a creeping ivy which never rises from the surface of the ground: bruised in wine, in doses of one acetabulum, it is curative of affections of the spleen, the leaves of it being applied topically with axle-grease to burns.
The smilax also, otherwise known as the “anthophoros,” has a strong resemblance to ivy, but the leaves of it are smaller. A chaplet, they say, made of an uneven number of the leaves, is an effectual cure for head-ache. Some writers mention two kinds of smilax, one of which is all but perennial, and is found climbing the trees in umbrageous valleys, the berries hanging in clusters. These berries, they say, are remarkably efficacious for all kinds of poisons; so much so indeed, that infants to whom the juice of them has been habitually administered, are rendered proof against all poisons for the rest of their life. The other kind, it is said, manifests a predilection for cultivated localities, and is often found growing there; but as for medicinal properties, it has none. The former kind, they say, is the smilax, the wood of which we have mentioned as emitting a sound, if held close to the ear.
Another plant, similar to this, they call by the name of “clematis:” it is found adhering to trees, and has a jointed stem. The leaves of it cleanse leprous212 sores, and the seed acts as an aperient, taken in doses of one acetabulum, in one hemina of water, or in hydromel. A decoction of it is prescribed also for a similar purpose.”

"[Plin. Nat. 24.88.] - THE CLEMATIS CENTUNCULUS; THREE REMEDIES.
We shall now have to annex some plants, of a marvellous nature no doubt, but not so well known, reserving those of a higher reputation for the succeeding Books.
Our people give the name of “centunculus,” to a creeping plant that grows in the fields, the leaves of which bear a strong resemblance to the hoods attached to our cloaks. By the Greeks it is known as the “clematis.” Taken in astringent wine it is wonderfully effectual for arresting diarrhœa: beaten up, in doses of one denarius, in five cyathi of oxymel or of warm water, it arrests hæmorrhage, and facilitates the after-birth.”
