The ephemeron930 has leaves like those of the lily, but smaller; a stem of the same height, a blue flower, and a seed of which no use is made. The root is single, about the thickness of one’s finger, and an excellent remedy for diseases of the teeth; for which purpose it is cut up in pieces, and boiled in vinegar, the decoction being used warm as a collutory. The root, too, is employed by itself to strengthen the teeth, being inserted for the purpose in those that are hollow or carious.

Root of chelidonia931 is also beaten up with vinegar, and kept in the mouth. Black hellebore is sometimes inserted in carious teeth; and a decoction of either of these last-mentioned plants, in vinegar, has the effect of strengthening loose teeth.
