Pregnancy common cold

It is a Chinese medicinal plant widely distributed in south China and used commonly for treatment of the common cold, laryngopharyngitis, acute gastroenteritis and diarrhea. It is also used as a contraceptive in some districts of Fujian Province. The aqueous extracts of this plant and its precipitate obtained by additing 95% ethanol showed significant effects on terminating pregnancy in rats. In order to elucidate its active principles, we systematically studied the hydrophilic components of the whole plant.
