The bark of the root Ptelea trifoliata.
Preparation.—Tincture of Ptelea.
Dose.—From one drop to half a drachm.
Therapeutic Action.—The Ptelea is tonic, stimulant, expectorant, alterative, astringent and diaphoretic. Among its uses may be noted its influence in some cases of asthma, greatly relieving the patient, and sometimes accomplishing a cure.
It is a good tonic and stomachic, and as such may be used in debilitated states of the system, in dyspepsia, anorexia, intermittents, convalescent stages of other diseases, and, in short, whenever a corroborant is demanded. We have found the tincture beneficial in chronic rheumatism. Others have used it in the same disease with advantage. Its pungent, excitant, tonic, diaphoretic, and alterative properties would seem to point to it as a useful remedy, in the chronic forms of that disease, attended with debility and requiring excitants.
