The tops of Cytisus scoparius.
Dose.—Of an infusion of one ounce to a pint of boiling water, one to two ounces. Of a decoction of one ounce to a pint and a half of water, boiled down to a pint, one to one and a half ounces.
Therapeutic Action.— Scoparius is diuretic, laxative, tonic, and in large doses emetic and cathartic. Mead and Cullom recommend it strongly for its diuretic properties. Pereira speaks of it as a powerful diuretic, and says: "I can not call to mind a single case in which it has failed to act upon the kidneys. In some cases it produces a most marked and beneficial effect upon the dropsical effusion. According to my experience it is more certain than any other diuretic in dropsies."
