The Plant For Treating Period Cramps, Sleep Issues & More

The deeper you dive into the world of herbalism, the more you come to realize that nature has already come up a cure for almost every ailment out there—from headaches to fatigue and beyond. One natural remedy that many herbalists have turned to for centuries is a medicinal plant known as black cohosh. While it hasn’t quite gone mainstream in the wellness world, black cohosh has shown potential to help women during their cycle and through menopause and also offer some relief to those struggling with PCOS. Here’s everything you need to know about adding it to your plant-powered health arsenal.

What is black cohosh?

Native to North America, black cohosh (actaea racemosa or cimicufuga racemosa) is also known as bugbane, mugwort, rattleroot, and black snakeroot. The medicinal plant grows in the Eastern deciduous forest and is wild harvested in the Appalachian and the Ozarks, and its power is packed in its roots and underground stems.

Black cohosh has been used across the world as a natural remedy for centuries. Algonquins took the herb internally to remedy kidney programs, while the Iroquois used it topically for achy joints to ease pain. In the case of the Cherokees, it was used as a diuretic and treatment for tuberculous and fatigue.

Black cohosh gained mainstream popularity in the late 19th century, when herbalist Lydia E. Pinkham started selling an herbal tonic to support women’s health (or, as she referred to it, “women’s complaints”) that included a variety of herbs including black cohosh. Though she was considered a little “off her rocker” at the time, her product is still sold and beloved by many.

Fast-forward to the current day, and black cohosh has been most readily prescribed in Europe for a range of symptoms related to women’s health and hormonal balance—usually in place of more conventional hormone replacement therapies. It is, however, banned in Denmark due to its potential links to liver damage.

Why does black cohosh help ease the symptoms of menopause? (Looking at you, hot flashes.)

First and foremost, black cohosh is a phytoestrogen—a naturally occurring product that contains estrogen-like properties. “I typically suggest black cohosh to my patients going through menopause as well as other hormone problems such as PCOS for its ability to help rebalance hormones,” shared Will Cole, D.C., IFMCP, a functional medicine practitioner. “Since black cohosh can also help improve sleep, it does double duty in hormone health since adequate sleep is essential for hormone production.”

And while black cohosh is often associated with supporting hormonal issues in women, many studies on its efficacy are inconclusive. Most of the research done on black cohosh focuses on Remifemin, a supplement for menopausal women that contains a regulated dosage of the herb (40 mg). Remifemin has been used in Europe since the 1950s to treat symptoms of menopause and has been heavily researched since then with mixed results.

While not all studies have found conclusive data, many have found enough evidence of potential efficacy to recommend additional studies. (One study concluded that taking black cohosh reduced hot flashes by showing it was more effective than a placebo, while another one found that it was no more effective than the placebo.)

As with many herbs, though, it’s considered relatively safe, so it may be worth trying out to see if it works for you.

What else might it be able to help with?

It helps menopausal women get some sleep.

Many women in the early stages of menopause complain of insomnia. One study showed that menopausal women reported having a better night’s sleep (“increased sleeping efficiency” and “decreased wake after sleep onset” were the terms they used) when taking black cohosh. The study did not find any negative effect of taking the herb.

It eases menstrual cramps.

Black cohosh has also been shown to be helpful for those who suffer from menstrual cramping. While there aren’t many research studies to back this up, herbalists have been prescribing the herb to women during their time of the month for decades.

It relieves symptoms of PCOS.

There’s some evidence that black cohosh may help reduce pain in patients with polycystic ovary syndrome (PCOS). One comprehensive review looked at 33 studies and concluded that there is evidence that black cohosh—along with vitex, tribulus, licorice, Paeonia lactiflora, and Chinese cinnamon—is an effective herbal medicine at easing symptoms such as irregular menstrual cycles, hirsutism, and acne. Another study even showed that women with PCOS who used the herb were more fertile than those who didn’t, but again, more research is needed.
