"[Plin. Nat. 26.93.] - APPLICATIONS FOR THE HAIR. LYSIMACHIA. OPHRYS.
Lysimachia imparts a blonde tint to the hair, and the hypericon, otherwise called “corisson,” makes it black. The same too, with ophrys, a plant with indentations, which resembles the cabbage, but has only two leaves. Polemonia, too, boiled in oil, imparts blackness to the hair.
As for depilatories, I reckon them in the number of cosmetics, fit for women only, though men use them now-a-days. For this purpose archezostis is looked upon as highly efficacious, as also juice of tithymalos, applied with oil every now and then in the sun, or after pulling out the hairs. Hyssop, applied with oil, heals itch-scab in beasts, and sideritis is particularly useful for quinzy in swine.”
