Blue cohosh is used for stimulating the uterus and starting labor; starting menstruation; stopping muscle spasms; as a laxative; and for treating colic, sore throat, cramps, hiccups, epilepsy, hysterics, inflammation of the uterus, infection of the female organs (pelvic inflammatory disease), over-growth of uterine tissue (endometriosis), and joint conditions.
In foods, the roasted seeds of blue cohosh are used as a coffee substitute.
How does it work?
It is thought that blue cohosh might have effects similar to the hormone estrogen. It also may narrow the vessels that carry blood to the heart that can decrease oxygen in the heart.
