"[Plin. Nat. 27.19.] - THE ASTER OR BUBONION: THREE REMEDIES.
The aster is called "bubonion" by some, from the circumstance of its being a sovereign remedy for diseases of the groin. It has a diminutive stem with oblong leaves, two or three in number; and at the summit it is surmounted with small radiated heads, like stars. This plant is taken also in drink as an antidote to the venom of serpents: but if required for the cure of inguinal complaints, it is recommended that it should be gathered with the left hand, and attached to the body near the girdle. It is of great service also, worn as an amulet, for sciatica.
