"[Plin. Nat. 21.99.] - FOUR REMEDIES DERIVED FROM THE VINCAPERVINCA.
The vincapervinca, too, or chamædaphne, is dried and pounded, and given to dropsical patients in water, in doses of one spoonful; a method of treatment which speedily draws off the water. A decoction of it, in ashes, with a sprinkling of wine, has the effect of drying tumours: the juice, too, is employed as a remedy for diseases of the ears. Applied to the regions of the stomach, this plant is said to be remarkably good for diarrhœa.”

"[Plin. Nat. 24.90.] - THE EGYPTIAN CLEMATIS, DAPHNOÏDES, OR POLYGONOÏDES: TWO REMEDIES.
There is another kind also, known as the “Egyptian” clematis, otherwise as “daphnoïdes” or “polygonoïdes:” it has a leaf like that of the laurel, and is long and slender. Taken in vinegar, it is very useful for the stings of serpents, that of the asp in particular.”
