Blue Cohosh

Caulophyllum thalictroides


This plant has yellow-green flowers, blue berry-like fruits, and bluish-purple foliage.


Spotted growing in a deciduous forest.


It has been used medicinally for ages, especially to induce labor. Although, the safety of this plant is seriously questioned and it is not generally regarded as a safe supplement.

Blue cohosh has effects similar to the hormone estrogen. It also narrows the vessels that carry blood to the heart, which can decrease oxygen in the heart.
