 minuria. Oil of juniper is indicated in chronic nephritis, 

 pyelitis and cystitis ; also in dropsy of cardiac, renal, or hep-

 into serous cavities, through its diuretic properties. The 

 compound spirit of juniper approximates gin in composition, 

 although it is not the official name for that liquor. This 

 preparation is useful in the convalescent period of acute
