Today, it is used in popular women’s health supplements to help regulate the monthly cycle, ease menopause discomforts, and fertility concerns (2).
Most women have to deal with hot flashes, excessive sweating, headaches, anxiety, mood swings, and vaginal dryness for about 3-4 years during their menopausei XThe time that marks the end of the monthly menstrual cycle at the age of 40-50s due to a decline in female reproductive hormones. . Black cohosh seems to act similar to the hormone estrogen and has pain-relieving effects that help alleviate these symptoms (2),(3). Going further, let’s understand these beneficial effects of black cohosh in detail.
Health Benefits Of Black Cohosh
Black cohosh has several potential benefits when it comes to hormonal balance and women’s health. However, apart from its effects in easing menopausal symptoms, all other benefits need more research to be established.
- May Help With Menopause
The primary benefit of black cohosh is its alleviating effects of menopausal pain and other symptoms. This is also strongly backed by many studies (4).
A study on menopausal women reported a significant reduction in hot flashes on a daily supplementation of 20 mg of black cohosh for 8 weeks (5). Another review of studies on menopausal women concluded a 26% reduction in hot flashes and night sweats on black cohosh supplementation in combination with other substances like St John’s wort, red clover flower extract, ginseng, soy extract, vitamin D, primrose oil, calcium, etc (6).
Black cohosh may provide pain-relief effects by binding to the body’s opioid receptors (7). Therefore it might be effective in reducing body pain and muscle aches during and after menopausei XThe time that marks the end of the monthly menstrual cycle at the age of 40-50s due to a decline in female reproductive hormones. .
- May Help Improve Fertility
Although there’s not much evidence to support this, black cohosh may help improve your fertility. Especially for women with PCOS, black cohosh seems to improve the efficacy of the fertility drug Clomid (clomiphene citrate) increasing their chances to conceive. A few human studies suggest an improvement in ovulationi XThe process when a mature egg is released from the ovary into the fallopian tubes during the monthly menstrual cycle. and chances of conception in women struggling with infertility on supplementation of black cohosh alongside Clomid (8), (9). Although, more research is needed to confirm this effect.
- May Help With Uterine Fibroids
Along with helping regulate your menstrual cycle and improving your chances of conceiving, black cohosh might also help improve the conditions of uterine fibroidsi XThey are growths made of uterine muscles, which are non-cancerous and appear in the uterus during the child-bearing years of life. . A 3-month study on postmenopausal women who took 40 mg of black cohosh daily, reported a 30% decrease in the size of their uterine fibroidsi XThey are growths made of uterine muscles, which are non-cancerous and appear in the uterus during the child-bearing years of life. (12).
- Might Help Decrease The Risks Of Cancer
Studies show that black cohosh may help decrease the risks of breast cancer (13). This is interesting since black cohosh behaves similar to the hormone estrogen (which may potentially increase your risk of breast cancer). Few test-tube studies also suggest that black cohosh may help restrict the spread of cancerous cells (14). Further research is warranted to establish the same.
- May Help Improve Mental Health
According to a review of studies on the effects of herbal supplementation in menopausal women, black cohosh might help menopausal women deal with mental health concerns better. They reported significant improvements in their psychological symptoms (15). However, more research is needed to confirm the same.
- May Help You Sleep Better
Black cohosh supplementation may help improve the duration and quality of sleep in menopausal women (16). As per a study, black cohosh in combination with other compounds like ginger, zinc, hyaluronic acid, and chaste berry might help improve hot flashes associated with anxiety and insomnia (17). However, it is not clear whether it is only because of black cohosh or any of the other ingredients involved.
- May Aid Weight Loss
Women nearing menopausei XThe time that marks the end of the monthly menstrual cycle at the age of 40-50s due to a decline in female reproductive hormones. tend to gain weight with a natural decrease in their estrogen levels. Black cohosh, with its estrogen-like effects, may have a slightly beneficial effect in managing and maintaining their weight (18). However, further human studies are needed to establish this.
People should exercise caution when considering or using black cohosh supplements. Studies on the risks of using it are limited even if numerous side effects have been associated with it.
Dosage And How To Take Black Cohosh?
Black cohosh roots and underground stems are commonly prepared and sold as capsules, ground powder, or liquid extracts. While there are no fixed dosage recommendations, they may vary between 20-120 mg based on different brands and varying health concerns (19).
Additionally, black cohosh is used as an herbal supplement in combination with red clover, soy isoflavones, St. John’s wort, and chaste berry (20), (21), (22), (23).
Since black cohosh seems to have potential effects on your hormones, you might experience changes in your menstrual cycle when you stop taking it. You should consult your doctor for any such concerns.
As the Food and Drug Administration (FDA) does not regulate supplements, the quality, strength, and amount of active ingredients in the product may vary from brand to brand. You should hence look for black cohosh supplements tested and approved by third-party testing organizations like United States Pharmacopeia (USP), NSF International, and ConsumerLab.
Some health professionals claim you should not take black cohosh for longer than 6 months to 1 year because of its potential long-term risks (19). Let’s have a detailed understanding below.
Side Effects Of Black Cohosh
Black cohosh has some potentially mild side effects. They may include nausea, digestive issues, infection, skin rashes, muscle pain, breast pain or enlargement, and bleeding or spotting outside your regular menstrual cycle (19).

Further research is needed to confirm the same for humans (24).
- May Worsen Prior Health Concerns

Because of its blood-thinning and hormonal effects, black cohosh might aggravate certain health issues in people with prior hormonal replacement therapy, breast or uterine cancers, endometriosisi XA disorder in which the endometrium tissue lining the uterus, which normally lies inside the uterus, grows outside the uterus. , liver disease, etc. (25).
- May Have Drug Interactions
There are few medications that might increase the chances of complications and adverse drug interactions adding to the potential side effects of black cohosh (26).
As black cohosh preparations are not regulated by the FDA, there is also a chance that products may contain other botanical or chemical ingredients that could cause harm.
- May Trigger Allergies
Some people might have certain allergic reactions to black cohosh. The herb may also contain small levels of salicylic acid, the active component in aspirin (27). People with aspirin intolerance or allergies should avoid it.
To Sum Up
Black cohosh is a perennial plant known for its remedial effects on women’s health. With its estrogen-like properties, it is used in modern health supplements for women to ease menstrual discomfort and treat menopausal symptoms. Though it has been in use traditionally, it is not regulated by the FDC, and hence should not be taken in large doses without consulting a health practitioner.
