"[Plin. Nat. 27.16.] - THE ARCTION OR ARCTURUM: FIVE REMEDIES.
The arction is by some called "arcturum" in preference: the leaves of it are like those of verbascum, except that they are more hairy; the stem is long and soft, and the seed resembles that of cummin. It grows in rocky localities, and has a tender root, white and sweet. A decoction of it is made with wine for tooth-ache, being retained for that purpose in the mouth. The plant is taken in drink for sciatica and strangury, and is applied with wine to burns and chilblains, which are fomented also with the root and seed bruised in wine.
