The Barberry of the gardens (which is the European variety) differs in some respects 

 from the B. Can adensis" above described. The berries are larger and more juicy. It 

 is cultivated for the berries and bark : the former are sour, and are used for their grate- 

 ful acid flavor. They are used in preparini: drinks in febrile diseases, and are said to 

 be antiscorbutic. The bark is used in medicine for jauudice, and in the arts for dye- 

 ing yellow. The coloring matter is a crysta'.li/able substance called berberin.
