Ptelea is an excellent tonic, hardly surpassed in its general uses by any agent of our Materia Medica, if we except Hydrastis. It may be employed in all atonic states of the stomach and upper intestinal canal, when it is desirable to increase the appetite and digestion. It is claimed to exert an influence upon the respiratory apparatus, but we have never noticed any action other than as a tonic.
