"[Plin. Nat. 20.28.] - LIMONION, OR NEUROIDES: THREE REMEDIES.
There is a wild beet, too, known by some persons as “limonion,” and by others as “neuroides;” it has leaves much smaller and thinner than the cultivated kind, and lying closer together. These leaves amount often to eleven in number, the stalk resembling that of the lily. The leaves of this plant are very useful for burns, and have an astringent taste in the mouth: the seed, taken in doses of one acetabulum, is good for dysentery. It is said that a decoction of beet with the root has the property of taking stains out of cloths and parchment.”

"[Plin. Nat. 25.97.] - MOLYBDÆNA: ONE REMEDY.
Molybdæna also grows everywhere in the fields, a plant commonly known as “plumbago.” It has leaves like those of lapathum, and a thick, hairy root. Chewed and applied to the eye from time to time, it removes the disease called “plum-bum,” which affects that organ.”
