Black Cohosh has been studied for its potential to help with some of the most challenging menopause symptoms. It is traditionally used in Western herbal medicine to help:
- Relieve hot flushes associated with menopause
- Relieve night sweats associated with menopause
- Reduce the occurrence of menopausal symptoms
This article breaks down its benefits, how it works and the science behind it.
What is Black Cohosh?
Black cohosh is a plant that is native to North America. Its scientific names are Actaea racemosa and Cimicifuga racemosa.1 This perennial herb thrives in woodland areas and is a member of the buttercup family.1 The plant is primarily known for its root and rhizome, which are the parts utilized in various remedies.1

Black cohosh has a long history of use by Native American tribes.1 Over time, its reputation has grown, and today it is traditionally used in Western herbal medicine to help reduce the occurrence of menopausal symptoms.
Black cohosh is often confused with other cohosh species, such as blue cohosh. However, these plants are distinct in their properties and uses, so it's worth checking labels carefully.1
The popularity of black cohosh in modern herbal medicine has led to the development of various supplements and preparations. From capsules to tinctures, black cohosh is available in multiple forms, making it accessible for those seeking herbal support for menopausal symptoms.
How Black Cohosh Works for Menopausal Symptoms
Menopause brings a slew of uncomfortable symptoms, including hot flashes, mood swings, and sleep disturbances. These symptoms can significantly disrupt daily life and well-being. Black cohosh has been studied as a potential herbal option for some of these symptoms, but how does it work?
Researchers are still working out exactly how black cohosh works, and it is not thought to increase hormone levels.2 Black cohosh is traditionally used in Western herbal medicine to help relieve hot flushes associated with menopause, one of the most common and bothersome menopause symptoms. These hot flashes are part of the vasomotor symptoms commonly experienced during menopause.
In addition to hot flashes, black cohosh is traditionally used in Western herbal medicine to help relieve night sweats associated with menopause. If you're experiencing other changes, such as vaginal dryness, talk to your health professional about the options that suit you.
Sleep is often disrupted during menopause.3 If sleep is a concern, it's worth talking to your health professional.
Though not a one-size-fits-all solution, black cohosh’s potential to relieve menopausal symptoms makes it a valuable option. For many women, it offers a natural pathway to manage the challenges of menopause.
Scientific Evidence on Effectiveness
The scientific community has shown considerable interest in black cohosh, particularly regarding its effectiveness in relieving menopausal symptoms. However, the evidence is mixed, with some studies suggesting benefits while others do not.4,5 Systematic reviews and meta-analyses have called for more rigorous research to conclusively assess black cohosh’s efficacy.4,5 While some studies report improvements in symptoms after two to three months of treatment, others find no significant difference compared to placebo.4,6,7 This discrepancy highlights the need for more well-designed, long-term studies to fully understand black cohosh’s potential.
Despite mixed results, some postmenopausal women report subjective improvements in their symptoms when using black cohosh. These anecdotal experiences, combined with some supportive studies, suggest that black cohosh may be a worthwhile option for those seeking natural relief from menopausal symptoms.
Insights from Clinical Trials
Clinical trials provide a closer look at the potential benefits and limitations of black cohosh. Some trials have reported a reduction in menopause-related symptoms compared to placebo, while others have found no significant difference.4,6
Some research has looked at specific symptoms, such as night sweats, which are part of the vasomotor symptoms of menopause.6 These findings suggest that black cohosh may have targeted applications, even if its overall efficacy for all menopausal symptoms is still under debate.
The mixed results from clinical trials underscore the importance of individualized treatment approaches. What works well for one person may not be as effective for another, highlighting the need for personalized medical advice and careful monitoring when using black cohosh in a randomized controlled trial.
Safety and Side Effects
Black cohosh isn't right for everyone, and it's important to be aware of possible side effects. Common side effects can include an upset stomach and a headache.8 Additionally, some individuals may experience a rash.2,8 These symptoms are usually mild.2
However, there have been rare instances of serious liver damage associated with black cohosh use.1 Although it’s uncertain if black cohosh directly causes these issues, it is sometimes recommended to limit its use to no more than six months.1,2 Monitoring liver health and consulting a healthcare provider before starting black cohosh is crucial.
Individuals with hormone-sensitive conditions, such as breast cancer, should avoid using black cohosh.1 Additionally, breastfeeding women should refrain from taking this herb to avoid potential risks to the infant.1
To ensure safety, it's essential to consult a healthcare provider before starting black cohosh, especially for those with existing liver diseases or other medical conditions that might interact with the herb.
Who Should Avoid Black Cohosh?
Certain groups of people should avoid black cohosh due to potential risks and side effects. Pregnant women, breastfeeding women, and individuals with breast cancer or at high risk for it should not use black cohosh.1,8 This herb can potentially exacerbate hormone-sensitive conditions, making it unsafe for these individuals.
Women who have had breast or uterine cancer, those with endometriosis, and children under 18 should also avoid black cohosh. The potential for hormone-like effects makes it unsuitable for these populations.
Individuals with liver disease should be particularly cautious, as black cohosh has been associated with rare instances of liver damage.1 Avoiding black cohosh in these cases helps prevent further complications and ensures overall health safety.
Potential Drug Interactions
Black cohosh can interact with various medications, potentially causing adverse effects or reducing the effectiveness of certain treatments.1,8
Because black cohosh can interact with a number of medicines, consulting a healthcare provider before starting black cohosh is essential. This precaution helps ensure that black cohosh does not interfere with other medications you may be taking.
Women should seek medical advice when combining black cohosh with other treatments. This step helps prevent potential complications and ensures that all medications work effectively and safely together.
