According to a study published by "The Journal of pharmacy and pharmacology", Scoparia dulcis L. is used in Brazilian folk medicine to treat bronchitis, gastric disorders, haemorrhoids, insect bites and skin wounds, while oriental medicine uses it for hypertension. Administration of an ethanolic extract at 0.5-2 mg kg-1 i.v. to anaesthetized rats produced dose-related hypertension blocked by 1 mg kg-1 of prazosin. An aqueous phase 20 times more potent than the extract produced concentration-dependent contractions in the vas deferens musculature at 1-3 x 10(3) micrograms mL-1, similar to noradrenaline at 10(-8)-10(-4)M. This aqueous fraction also increased inotropism in rat left atria at 25 and 50 micrograms mL-1, and relaxed histamine-induced contractions in guinea-pig tracheal rings at 1-3 x 10(3) micrograms mL-1. The plant extract contains both noradrenaline and adrenaline, which may account for its hypertensive and inotropic effects.
