"[Plin. Nat. 25.102.] - THE GREATER AIZOÜM, ALSO CALLED BUPHTHALMOS, ZOÖPHTHALMOS, STERGETHRON, HYPOGESON, AMBROSION, AMERIMNON, SEDUM MAGNUM, OR DIGITELLUS: THIRTY-SIX REMEDIES. THE SMALLER AIZOÜM, ALSO CALLED ERITHALES, TRITHALES, CHRYSOTHALES, ISOËTES OR SEDUM: THIRTY-TWO REMEDIES.
Of the plant known as aizoüm there are two kinds; the larger of which is sown in earthen pots. By some persons it is known as “buphthalmos,” and by others as “zoöphthalmos,” or else as “stergethron,” because it forms an ingredient in the composition of philtres. Another name given to it is “hypogeson,” from the circumstance that it generally grows upon the eaves of houses: some persons, again, give it the names of “ambrosion” and “amerimnon.” In Italy it is known as “sedum magnum,” “oculus,” or “digitellus.” The other kind of aizoüm is more diminutive, and is known by some persons as “erithales” and by others as “trithales,” from the circumstance that it blossoms three times in the year. Other names given to it are “chrysothales” and “isoëtes:” but aizoüm is the common appellation of them both, from their being always green.
The larger kind exceeds a cubit in height, and is somewhat thicker than the thumb: at the extremity, the leaves are similar to a tongue in shape, and are fleshy, unctuous, full of juice, and about as broad as a person’s thumb. Some are bent downwards towards the ground, while others again stand upright, the outline of them resembling an eye in shape. The smaller kind grows upon walls, old rubbish of houses, and tiled roofs; it is branchy from the root, and covered with leaves to the extremity. These leaves are narrow, pointed, and juicy: the stem is a palm in height, and the root is never used.”

"[Plin. Nat. 26.92.] - MASTOS: ONE REMEDY.
Aizoüm, which we have spoken of under the name of digitellus, is the great specific for diseases of the mamillæ. The milk is increased by taking erigeron in raisin wine, or else sonchos boiled with spelt. The plant known as “mastos,” applied topically, removes the hairs from the mamillæ, which make their appearance after child-birth: it has the effect also of dispersing scaly crusts upon the face, and other cutaneous affections. Gentian also, nymphæa heraclia employed in a liniment, and root of cyclaminos, remove all blemishes of the skin. Seeds of cacalia, mixed with melted wax, plump out the skin of the face and make wrinkles disappear. Root of acoron, also, removes all spots upon the skin.”
