Description of the substance

Plant Description
Jamaica dogwood is indigenous to Central America, Florida, and the West Indies, and can now also be found in Texas, Mexico, and the northern part of South America. The plant's characteristic pods bear four projecting longitudinal wings. The bark is yellow or grayish brown on the outer surface, and lighter colored or white on the inner surface. The Jamaica dogwood's distinctly acrid and bitter taste causes a burning sensation in the mouth, and the bark gives off an unpleasant odor.

---Description---A tree with very valuable wood and with the foliage and habit of Lonchocarpus. The pods bear four projecting longitudinal wings. The pounded leavesand young branches are used to poison fish the method followed is to fill an open crate with the branches, drop it into the water, and swill it about till the water is impregnated with the liquid from the leaves, etc.; this quickly stupefies the fish and enables the fishers to catch them quickly. In commerce the bark is found in quilled pieces 1 or 2 inches long and 1 inch thick. The outer surface yellow or greyish brown, inner surface lighter coloured or white, and if damp a peculiar blue colour. Inside it is very fibrous and dark brown, taste very acrid and bitter, and produces burning sensation in mouth with a strong disagreeable smell like broken opium. In 1844 attention was called to its narcotic, analgesic and sudorific properties which are uncertain.
