The active jiroperties of the family are most conspicuous in species of Strychnos. The fatal drug, Niix-vomica, from which strychnine is extracted, consists of the seeds of an East Indian Strychnos. Tieute, another frightful poison, is prepared from a Java species, and the Ouari poison of South America, from a third species. Meanwhile a Brazilian species, S. Pseudoquina, has a liarm- less fruit, and its bark (Copalche hark) is reputed to be an excellent febrifuge, fully equal to Cinchona. 842. Ord, Valerianaceffi ( Valerian Family).
