"[Plin. Nat. 25.100.] - THE ACORON OR AGRION: FOURTEEN REMEDIES.
The acoron has leaves similar to those of the iris, only narrower, and with a longer stalk; the roots of it are black, and not so veined, but in other respects are similar to those of the iris, have an acrid taste and a not unpleasant smell, and act as a carminative. The best roots are those grown in Pontus, the next best those of Galatia, and the next those of Crete; but it is in Colchis, on the banks of the river Phasis, and in various other watery localities, that they are found in the greatest abundance. When fresh, they have a more powerful odour than when kept for some time: these of Crete are more blanched than the produce of Pontus. They are cut into pieces about a finger in length, and dried in leather bags in the shade.
There are some authors who give the name of “acoron” to the root of the oxymyrsine; for which reason also some prefer giving that plant the name of “acorion.” It has powerful properties as a calorific and resolvent, and is taken in drink for cataract and films upon the eyes; the juice also is extracted, and taken for injuries inflicted by serpents.”
