PULVANE
In a twelve-page pamphlet, sent out by the Pulvane Laboratories, Inc., of Des Moines, Iowa, and purporting to deal with “The Therapy of Pulvane, an advanced method for the treatment of Respiratory Diseases,” we are told that Pulvane “was developed in a United States Army General Hospital by officers of the Medical Department.”
Pulvane “originally was intended only for its germicidal action upon tubercle bacilli in the lung,” but it is now also recommended for asthma, hay fever, bronchitis, rhinitis, laryngitis and “other affections of the air passages.” Of the alleged action of Pulvane on tuberculosis we read:
“It destroys the spores of the bacilli as well as the germs themselves. It prevents infection of new areas by aspiration, gravity or surface contact.
“In cases where sputum is positive it is a very noteworthy fact that shortly after treatment is begun, the bacilli begin to disappear, gradually diminish in number, and finally the sputum becomes negative.”
Pulvane is administered, by inhalation, at the offices of the Pulvane Laboratories, Inc. Its “discoverer” chanced on a method of “introducing into solution and volatizing a certain germicide, extremely rare in its usage because of its resistance heretofore to attempts to bend it to scientific will.” This “rare” medicament is alpha naphthol! But since the discovery of this volatizing method “three other ingredients of high therapeutic value have been added.” What are these other ingredients?
“They would be named were it not that Pulvane requires special technique in its preparation and administration. Our medical directors do not consider it advisable to identify them here because of the possibility of incompetent hands attempting their use. The medical directors, however, will be glad to name every ingredient of Pulvane for any reputable member of the profession. Pulvane Laboratories reserve only the method of compounding.”
