Caulophyllum thalictroides

Specific Indications. - Uterine pain with weight and fullness and pains in the legs; sense of pelvic congestion; sluggish labor pains; as a partus praeparator.

Action and Therapy. - Caulophyllum is a good emmenagogue. It may be used where there is congestion with irritation, and the natural functions are badly performed. In troubles dependent upon such irregularities, it has given fair results, though macrotys (Black Cohosh) has supplanted it for most conditions.

Uses

It was used as a medicinal herb by American Indians, and can also be used as a dietary supplement that can induce labor, regulate menstrual flow, suppress menstruation, and ease the pain and difficulty that accompany childbirth. Many Native American tribes and later European herbologists and mid-wives would use this herb in conjunction with other herbs and fluids for abortive and contraceptive purposes. As such, this herb should not be taken during pregnancy.
