Black cohosh, also known as black snakeroot, fairy candle, or bugbane, is a flowering plant native to North America. It thrives in the wet Pacific Northwest climates, both in the wild and cultivated in gardens and parks. It is best known for its medicinal usage as a female reproductive tonic and for providing mild rheumatism relief.


Black Cohosh is an herbaceous perennial herb that grows in moist, heavy soils; it produces tall, tapering racemes, or clusters of white midsummer flowers. It sprouts compound leaves that are vibrant green and textured.

Cultivation and Harvesting:

Black Cohosh can be found on the west side of the Cascades, in wetlands, river basins, and coastal forests. It is happiest in old growth forests with rotting nurse trees, thriving wildlife, and amongst companion plants such as trillium and devils club. Black Cohosh needs the variety of insects found in a healthy, complete forest for pollination. 1

Southern Oregon Cultivation:

Black Cohosh, although considered endangered by United Plant Savers, is found in heavily shaded woodland areas, and stands usually thrive in hilly, deciduous wooded lands. There are few areas in Southern Oregon to find wild Black Cohosh, but it's responsible reintroduction into its proper growing climate is highly recommended.

History and Folklore:

The name cohosh comes from the Algonquian word for “rough.”

The root decoction was used to address mild pain during menstruation and childbirth, uncomfortable menopausal symptoms, and to regulate the menstrual cycle. The root was also used as a poultice to treat venomous snake bites.

Herrick records that among the Iroquois the root decoction of Black Cohosh, whose common name translates to "horse smells" and "smells like horse" amongst tribal tradition,  was used to promote the flow of milk in female bodied individuals; it was used to treat rheumatism by decocting the root in a foot bath, and washing the affected parts. A steam or sweat bath was also prepared using the leaves and root. In some cases, leaves were used as a poultice to treat a baby’s sore back, and for general muscle aches.4

Traditional Usage: general occasional pain relief, help diminishing night sweats, ease of menstrual cramps, supporting healthy menstrual cycles, uterine tonic, ovarian anti inflammatory support, and to support vaginal dryness relief. 

Modern Applications:

There is substantial evidence from modern clinical trials confirming the traditional uses of black cohosh for treating premenstrual tension and other gynecological issues.2 It is one of the herbs approved by the German Commission E, which approved use of the root for premenstrual discomfort, dysmenorrhea or climacteric (perimenopausal or postmenopausal) neurovegetative ailments. Black Cohosh is used as primary remedy for rheumatism and myalgic pain.4,5

Uses and Preparations:

Dried Herb Tea Preparation: 

Up to 2 grams per day in leaf tea and/or root decoction.

Using a reusable tea bag or tea ball, immerse the loose dried herbs into boiling water and allow to steep for 5-10 minutes, preferably covered, in order to release the maximum amount of herbal goodness. Some herbal tea can carry a strong flavor. We recommend organic honey as a sweetener which preserves the beneficial herbal compounds. 


Up to 2-4 mL daily, and as needed for acute situations.  Exceeding the suggested dosage may cause mild frontal headaches, nausea, and gastric discomfort.

Some herbal tinctures can have a strong flavor on their own. Adding your tincture to a glass of 6-8oz of water is one easy way to help, should you wish to dilute the flavor.
