The Sumach as thus prepared exerts a direct influence upon the processes of waste and repair—alterative. It has not been much used, and we can not tell whether it will prove better than others of this class; still it deserves a thorough trial. It is claimed to be antidotal to the action of mercury, especially in chronic mercurial disease, and has been employed in the treatment of secondary syphilis, after mercurialization, with advantage.
