Simaba Cedron. Nat. ord., Simarubaceae.

Habitat. - New Granada and Central America.

Part employed. - The seed.

The Cedron "is a small tree, with an erect stem not exceeding 6 inches in diameter, branching at top in an umbellate form, with large glabrous, pinnate leaves, and pale brown flowers, in long branching racemes. The fruit is a large, solitary drupe, containing a single seed. The whole plant appears to be impregnated with a bitter principle, but it is the seed only which is used." The dried fruit "is light, of a yellowish ash-colour, flattish-ovate, with one edge convex, the other nearly straight, the convex outline terminating at each end in an obtuse point, of which that at the apex is most prominent. It is about 2 inches long, and 16 lines in its greatest breadth. Within, the seed is loose and movable. The seed itself is about 1 1/2 inch long, 10 lines broad, and 1/2 inch thick. It is convex on one side, flat or slightly concave on the other, and presents an oval scar near one extremity of the flat surface. It is hard and compact, but may be readily cut with a knife.

"Cedron seed is inodorous, but of a pure and intensely bitter taste, not unlike that of Quassia. It yields its virtues to water and alcohol. Mr. Lowry obtained from it a crystalline substance, intensely bitter, freely soluble in boiling water, and neutral to test-paper, which he supposes to be the active principle, and proposes to name Cedrin. He obtained it by first exhausting Cedron with ether, then treating it with alcohol, and crystallizing from the tincture.'"

The above description is extracted from Wood and Bache's "United States Dispensatory" (13th Ed.), and is given at length, as, from the mystery that hung about it from what is said in Teste's "Materia Medica," a valuable medicine was likely to fall into disrepute.

It has long enjoyed a reputation, employed externally and internally in snake-bites, though, like some others of this class, its virtues may be exaggerated. It has been used as a preventive of Hydrophobia, and as a remedy for Intermittent Fever, etc.

A description of the plant is given by S. W. J. Hooker (vide Pharm. Journ., Jan., 1851., x., 344).
