This is a crystalizable substance, obtained from the piper nigrum, longum, and even from cubebs; when pure it is white, but, as found in the market, of a straw-yellow color. It is tasteless and inodorous.
It has been recommended and employed in the treatment of intermittent fevers, with some success. We have used it in this class of diseases, where quinine could not be taken, in some cases successfully, but in a majority it entirely failed.
It was recommended by Magendie as a substitute for cubebs in blenorrhagia.
