Warning : Blue cohosh is a toxic herb. Natural and Alternative Treatments (NAT) strongly recommends against using it.
What Is Blue Cohosh Used for Today?
There is no credible evidence that blue cohosh is effective for any of the conditions for which it has been used. Furthermore, several published reports cite cases of serious side effects to infants apparently caused by blue cohosh. (See Safety Issues.)
Blue cohosh is usually used as a tincture. Common dosages range from 5 to 10 drops taken every 2 to 4 hours.
There are many serious safety concerns with blue cohosh.
Given these reports, the availability of safe alternatives for stimulating labor, and the lack of studies to document the herb's efficacy and safety, NAT strongly advises against using blue cohosh.
