Blue Cohosh: What It Is and How to Use It
Blue cohosh (Caulophyllum thalictroides) is a woodland plant native to eastern North America, whose root was used in Native American traditional practice — most famously by midwives, which earned it the folk name "squaw root." You can find it at William's Natural Foods, 12249 San Pablo Ave, Richmond, CA 94805, in our bulk herb section.

Frequently Asked Questions
Is blue cohosh the same as black cohosh?
No — the similar names cause endless confusion, but they are unrelated plants. Blue cohosh (Caulophyllum thalictroides) is in the barberry family, while black cohosh (Actaea racemosa) is in the buttercup family, and they have different traditional uses. Always check the Latin name on the bin to make sure you are getting the right one.
What was blue cohosh traditionally used for?
Native American tribes used blue cohosh root in traditional practice, and 19th-century Eclectic physicians included it in their herbal repertoire. Folk tradition strongly associated it with women's reproductive wellness. These are historical and traditional uses, not medical recommendations — and importantly, traditional midwifery use does not mean it is safe in pregnancy; modern references advise against using it during pregnancy except under qualified professional guidance.
What does blue cohosh taste like?
The root is bitter and somewhat acrid, with an earthy character typical of traditional medicinal roots. It was historically prepared as a decoction (simmered in water) or tincture rather than drunk as a pleasant tea. In blends, small amounts are combined with better-tasting herbs.
How should blue cohosh be stored?
Keep the dried root in an airtight container in a cool, dark place. Cut root pieces hold their quality for a year or longer when stored properly. As with all dried herbs, replace it if it develops a musty smell or looks faded.
Did you know? Blue cohosh produces one of the most unusual fruits in the eastern woodlands — its bright blue, berry-like seeds sit exposed on thick stalks after the fleshy coating splits, a structure botanists call a "naked seed" that looks like a tiny blue marble on a stem (source: U.S. Forest Service plant profiles).
