HelloPharmacist Scorecard of Black Cohosh 40 mg by Nature's Way
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Black Cohosh 40 mg contains one active ingredient: Black Cohosh root and rhizome extract. The inactive ingredients are cellulose, sodium croscarmellose, stearic acid, and silica — standard binders and fillers that help hold the tablet together.
Does it work?
Moderate evidence
Black cohosh is possibly effective for menopausal symptoms, based on the evidence we hold. For acne, sexual dysfunction, anxiety, and breast cancer-related hot flashes, the evidence isn't established well enough to rate.
If you're considering this for one of those other uses, talk to your pharmacist or doctor about what the science actually supports.
How safe is it?
Well-documented data
Black cohosh is generally well tolerated at typical doses, but there are a few things to know. The most common side effects are mild — breast tenderness, dizziness, nausea, headache, irritability, rash, or tiredness.
Rare but serious concerns include liver damage (hepatotoxicity) and endometrial hyperplasia (overgrowth of uterine tissue), though the evidence on both is conflicting. There's also one case report of serotonin syndrome when black cohosh was added to antidepressants.
During pregnancy, the safety data advises against it — not enough is known about how it affects the developing baby, and it may have effects on the uterus. The same goes for breastfeeding: safety hasn't been established, so it's best avoided.
Meds to double-check
Moderate interaction found
Before taking this product, double-check your medications with a pharmacist if you're on serotonergic drugs like SSRIs or SNRIs (antidepressants), CYP2D6 substrates (a wide category of common medications), hepatotoxic drugs (liver-stressing meds), atorvastatin, cisplatin, estrogen therapy, or OATP substrates. The serotonin and liver interactions carry the most weight.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you're dealing with menopausal hot flashes and your doctor has given you the go-ahead, black cohosh may help. But if you take antidepressants, blood pressure drugs, cholesterol medications, or anything that stresses your liver, you need to check with your pharmacist first.
Avoid it if you're pregnant or breastfeeding.

General Statements
Native to eastern North America, near the Appalachian mountains, black cohosh has traditionally been used by Native Americans for hundreds of years. It grows wild and is called the "fairy candle" due to the tall white flower that grows from the stem. However, the root is what the wild foragers are after, and is dug up in the autumn, dried and powdered.

Black Cohosh 40 mg by Nature's Way Drug Interactions
HelloPharmacist Interaction Report
Black Cohosh 40 mg by Nature's Way does interact with several medication types, and the most serious concern involves serotonergic drugs (antidepressants and similar medications).
Black cohosh can increase serotonin activity in your brain, and combining it with drugs like SSRIs or SNRIs raises the risk of serotonin syndrome — a condition marked by agitation, confusion, rapid heart rate, and high blood pressure.
Read the full breakdown — every affected drug type, severity by severity
There are also moderate-severity concerns with CYP2D6 substrate drugs (a large group metabolized by your liver), hepatotoxic drugs (medications that can stress the liver), atorvastatin (a cholesterol drug), cisplatin (a cancer drug), estrogen therapy, and a minor concern with OATP substrate drugs. The hepatotoxic interaction is particularly worth noting: there's concern that black cohosh itself may be linked to liver damage in rare cases, and combining it with other liver-stressing medications could compound that risk.
One ingredient in this product — Black Cohosh root and rhizome extract — is the only active component. We hold documented interaction data for it.
Altogether, these interactions span 636 individual medications.

For each ingredient in Black Cohosh 40 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Black Cohosh root and rhizome extract
Atorvastatin (Lipitor)
Taking black cohosh with atorvastatin might increase the risk for elevated liver function tests.
In one case report, a patient taking atorvastatin (Lipitor) developed significantly elevated liver function enzymes after starting black cohosh 100 mg four times daily. Liver enzymes returned to normal when black cohosh was discontinued. It is unclear whether the elevated liver enzymes were due to black cohosh itself or an interaction between atorvastatin and black cohosh.
Cisplatin (Platinol-Aq)
Theoretically, black cohosh may reduce the clinical effects of cisplatin.
Animal research suggests that black cohosh might decrease the cytotoxic effect of cisplatin on breast cancer cells.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Some research suggests that black cohosh might inhibit CYP2D6, but there is conflicting evidence.
Some clinical research suggests that black cohosh might modestly inhibit CYP2D6 and increase levels of drugs metabolized by this enzyme. However, contradictory clinical research shows a specific black cohosh product (Remifemin, Enzymatic Therapy) 40 mg twice daily does not significantly inhibit metabolism of a CYP2D6 substrate in healthy study volunteers. Until more is known, use black cohosh cautiously in patients taking drugs metabolized by CYP2D6.
Estrogens
Theoretically, black cohosh may alter the effects of estrogen therapy.
Some research suggests that black cohosh has estrogenic effects. This may enhance or inhibit the effects of estrogen therapy.
Hepatotoxic Drugs
Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
There is concern that black cohosh might be linked to cases of liver failure and autoimmune hepatitis.
Serotonergic Drugs
Combining serotonergic drugs with black cohosh might cause additive serotonergic effects.
Black cohosh might increase the risk of serotonin syndrome when combined with other serotonergic drugs. Black cohosh acts as an agonist at several serotonin receptor subtypes and might interact with other serotonergic medications. In one case, a 55-year-old female who had been on stable treatment with sertraline 50 mg and duloxetine 60 mg daily developed serotonin syndrome after taking black cohosh extract 40 mg daily for 3 days.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Black cohosh may inhibit one form of OATP, OATP2B1, which could reduce the bioavailability and clinical effects of OATP2B1 substrates.
In vitro research shows that black cohosh modestly inhibits OATP2B1. OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
