"[Plin. Nat. 26.65.] - LAPPAGO OR MOLLUGO: ONE REMEDY. ASPERUGO: ONE REMEDY.
Lappago is employed also for this disease; a plant similar to the anagallis, were it not that it is more branchy, bristling with a greater number of leaves, covered with rugosities, full of a more acrid juice, and possessed of a powerful smell. The kind that resembles anagallis most closely, is known as mollugo. Asperugo is a similar plant, only with a more prickly leaf. The juice of the first is taken daily, in doses of one denarius, in two cyathi of wine.”
