Lead-Wokt, or Plum logo, L. a genus of exotic plants, consisting of four species ; the most remarkable of which is the Euro-paea : its root is perennial, strikes deep into the ground, and grows naturally in the southern parts of Europe.

This very acrid and poisonous vegetable may be propagate d either by parting the roots, or by the seeds ; as it will grow in the open air of our climate, and is far from being an useless plant. Its root was formerly kept in the shops, and is still occasionally employed for drawing blisters, and exciting salivation.—The leaves of lead-wort, according to BEchstein, are vulnerary, and may be advan-:usly applied to the back of horses injured by the pressure of the saddle, or for healing other sores.
