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.

Appearance

From the single stalk rising from the ground, there is a single, large, three-branched leaf plus a fruiting stalk. The bluish-green leaflets are tulip-shaped, entire at the base, but serrate at the tip. Its species name, ''thalictroides'', comes from the similarity between the large highly divided, multiple-compound leaves of meadow-rue and those of blue cohosh.

It is found in hardwood forest of the eastern United States, and favors moist coves and hillsides, generally in shady locations, in rich soil. It grows in eastern North America, from Manitoba and Oklahoma east to the Atlantic Ocean.
