Common Broom(Spartium scoparium)
Diuretic and cathartic. Broom tops are used in the form of decoction and infusion, often with squill and ammonium and potassium acetate, as a feeble diuretic, generally in dropsical complaints of cardiac origin. The action is due to the Scoparin contained, whose action on the renal mucous membrane is similar to that of Buchu and Uva-Ursi.
A compound decoction of Broom is recommended in herbal medicine as of much benefit in bladder and kidney affections, as well as in chronic dropsy
It is found to produce a transient rise in arterial pressure, followed by a longer period of decreased vascular tension. Small doses slow the heart for a short period of time and then hasten its rate and at the same time increase the volume of the pulse. Those who advocate its employment claim that it is a useful heart tonic and regulator in chronic valvular disease. It has no cumulative action, like Digitalis.
In large doses, Sparteine causes vomiting and purging weakens the heart, depresses the nerve cells and lowers the blood pressure and has a strong resemblance to the action of Conine (Hemlock) on the heart. In extreme cases, death is caused by impairing the activity of the respiratory organs
