demand for " concentrations " was the means of discover- 

 ing the two alkaloids contained in this drug — Hydrastin 

 — the white, and Berberine — the yellow, besides others 

 of less value. For many years these and the powdered 

 root were the chief forms administered. Latterly, 

 however, the whole drug in the form of a fluid extract 

 is the most used and popular. It is a very valuable 

 remedy in disordered states of the digestive apparatus. 

 As a general bitter tonic it is applicable to debilitated 

 conditions of mucuous tissues. As a remedy for various 

 gastric disorders it takes a leading place, acting very 

 beneficially in acute inflammatory conditions. It will be 

 found of value in all cases of dyspepsia, biliousness and 

 debility of the system. It is especially indicated in 

 catarrhal states of the mucous membranes, gastric 

 irritability, and passive hemorrhages from the pelvic 

 tissues. Externally it is used as a lotion in treatment 

 of eye affections and as a general cleansing application.
