Catalpa.

Catalpa. Catalpa bignonioides Walt. Catalpa-tree, or Catawba-tree. Indian Bean.—This is a beautiful, indigenous, flowering tree, of the fam. Bignoniaceae, the seeds of which have been employed in asthma. Eugene O. Eau obtained from them tannin and a bitter crystalline principle. (A. J. P., xlii, 204.) F. K. Brown obtained from the seeds resin, fixed oil, tannin, sugar, and two crystalline bodies, their exact nature not being determined. (A. J. P., 1887, 230.) I. Schneck states that large doses cause nausea, vomiting, and slow, weak, intermittent pulse. He gave two fluidrachms (7.5 mils) of the tincture (1 oz. troy to 1 pint) every one to three hours.
