Black Cohosh

Black Cohosh

Black cohosh (Actaea racemosa) is an herbaceous flowering plant of the buttercup family. It often thrives in the woodland in North America and is a popular herbal medicine for many centuries. It is widely used in treating menstrual and menopausal problems. But more than its potent medicinal value, the black cohosh also makes a fine addition to ornamental gardens. It bears fluffy white flowers that look best in a cottage garden or woodland setting.

The plant exudes a sweet but fetid smell, but it is still used in flower arrangements because of its ornamental essence. Black cohosh also has a wildlife value with its ability to attract butterflies like the Appalachian Azure, Spring Azure, and Holly Blue. Instead of feasting on its leaves, these caterpillars prefer to devour the flowers instead.

The Actaea racemosa was formerly known as the Cimicifuga racemosa and was first used by the Native Americans. It was traditionally used for treating malaise, kidney disorders, gynecological problems, and inflammations. The North American colonists treat bronchitis, yellow fever, snakebite nervous problems, and uterine disorders with black cohosh. When the plant reached Europe in the 17th century, locals used it as an aid for pregnancy and labor pain.

Where Black Cohosh Is Found

Where to Find Black CohoshBlack cohosh originated from eastern North America.

It is abundant in the woodlands of Maine, Georgia, Missouri, and Arkansas. This terrestrial plant thrives in places with moisture-retentive soil and dappled shade.

The Eastern United States is still the largest producer of black cohosh, which supports the demand for herbal medicine in treating menopausal problems.

Actaea racemosa is a member of the Ranunculaceae or buttercup family. The name cohosh comes from the Algonquin word which means the appearance of rhizomes. There are around 20 recognized species of the Actaea genus, formerly known as the Cimicifuga genus. It is a close relative to baneberry.

The A. racemosa has two popular varieties: dissecta with deep-cut leaflets, and cordifolia with maple-like leaflets. Other varieties known cultivars of the black cohosh are:

  • Racemosa atropurpurea or the purple-leaf cultivar
  • Racemosa brunette with the darker foliage

The black cohosh should not be confused with the blue cohosh. The latter has a nicotine-like property and is without any research evidence to prove its safety.

How To Grow Black Cohosh

Black cohosh is a naturally appearing plant in its native home, but rare in non-conducive locations. It will proliferate best through its underground rhizomes. If you don’t have an existing plant, there are some varieties of A. racemosa in online herb and seed stores.

The plant is hardy in temperate climates and will grow in USDA 4 to 9. The plant has large roots and may not be ideal for container planting. Outside in the garden, they need to be planted 20-inches apart to allow the roots to grow. Black cohosh will do best in a garden that receives dappled sunlight, preferably under canopies.

Growing Black Cohosh from Seeds

Black cohosh is quite tedious to grow from seeds. It has a slow and low germination rate compared to its rhizomes and cuttings. But if you don’t have a parent plant, using seeds is a viable way of starting black cohosh.

The seeds need stratification or exposure to warm temperatures and then cold to germinate successfully. Expose the seeds to 70⁰F temperature for two weeks and transfer them to the fridge at 40⁰F for three months.

Plant the seeds directly in the garden if possible, or indoors about ¼-inch deep and 2-inches apart. Cover them with about two-inch of leaf mulch. Water and keep the layers moist until the seeds germinate.

If you sow them indoors, transfer the seedlings in spring when two sets of leaves appear in the plant.

  • Rich, organic, and well-draining soil with pH between 5.1 to 6.0
  • Generous amount of water without soaking
  • Pruning in spring
  • Partial shade

Harvesting Black Cohosh

Black cohosh roots are ready for harvest in four to five years if you start them from seeds. If you start them from rhizomes, they are well enough after three years. The best season for gathering their roots is in the fall when their weight and bioactive compounds are at their peak.

Normally, black cohosh roots are cleaned, dried, dehydrated, and stored until ready for use. You can dry the cleaned roots in an herb dryer or dehydrator at low heat and high airflow. Alternatively, you may keep them in a dry place with a temperature between 80 to 95⁰F for several weeks to air dry them.

Once they are thoroughly dried, keep them in burlap sacks in a cool, dark, and dry location. These roots will keep for less than a year.

    I have taken black cohosh in a pill form (80mg) twice a day for years to control my hot flashes. This article says not to take for more than 6 months. Now I’m scared. What can I take in the mean time if I take a break from black cohosh? How long of a break from it do I need?

    • Lezley Posted June 10, 2022 12:01 PM

      Hi Elaina-I used a product called Body Balance which helped a lot. All it is is Aloe and seaweed which is high in minerals. Generally our diets fall short in that area so you might want to look at that. Hope that helps.

    • Michele Posted June 10, 2022 12:23 PM

      I can’t answer you about black cohosh, but I used to have the night sweats, and learned that a capful of raw apple cider vinegar with mother in a large glass of water taken 1-2 times a day totally eliminated the sweats…

    I used 2 caps before bedtime every night for 10 years to replace Premarin after a hysterectomy at 24. I did not have any ill effects. Still no cancer at 63. It helped me keep calm with a raging, angry husband around and I was able to sleep well.
