Hydrangea Arborescens.

Botanical name: 

Syn.—Hydrangea; Seven Barks.
P. E.—Root.
N. O.—Saxifragaceae.
N. H.—United States.

Properties: Tonic, diuretic, cathartic.

Indications: Frequent urination, accompanied by a sense of burning and sharp, quick pain in the urethra. Pain from the irritation of passing renal sand. Aching in the back with irritation and partial suppression of urine.

Use: It is a mild but permanent tonic to the mucous structure of the genito-urinary apparatus. Corrects the tendency to formation of calculi. We think of it in lithemia, acute nephritis and irritation of the urinary apparatus, especially of an acute nature. It appears to have a favorable action in preventing the formation of calculi, and if formed relieves the pain when passing. In irritation from presence of uric acid and phosphoric crystals it is of value.
