Under the name of Cascara Cordial, Parke, Davis & Co. have long made a palatable preparation of cascara, which enjoys the confidence of those who use it. Kasagra, or Cascara Aromatica, is a liquid preparation of cascara sagrada, used extensively by physicians, made by Frederick Stearns & Co., of Detroit.
