HelloPharmacist Scorecard of Blue Cohosh Root by Mountain Meadow Herbs
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
This product contains one active ingredient: blue cohosh root extract, a liquid herbal preparation. The extract is mixed with vegetable glycerin, distilled water, and organic grain alcohol as inactive ingredients that help preserve and deliver the herb.
Does it work?
Moderate evidence
Blue cohosh root is possibly effective for menopausal symptoms — the main use for this ingredient. For other conditions including acne, sexual dysfunction, anxiety, and breast cancer-related hot flashes, the evidence in our data is insufficient to say whether it works or doesn't.
How safe is it?
Well-documented data
Blue cohosh root is generally well tolerated at typical doses when used short-term, though the rare liver concerns we noted mean it's smart to check with your pharmacist or doctor first. Common side effects that some people report include breast tenderness, dizziness, stomach upset, headache, irritability, rash, and tiredness.
Serious adverse effects are rare but have been documented — most notably liver damage in isolated cases. The product should be avoided during pregnancy because there isn't enough safety data and the herb may affect the uterus; it should also be avoided while breastfeeding since safety has not been established.
Meds to double-check
Moderate interaction found
Before taking this product, double-check if you're on any serotonergic drugs — that's antidepressants, certain migraine medications, and similar drugs that affect serotonin. Also mention if you take drugs metabolized by the liver enzyme CYP2D6, any medication that can harm the liver, estrogen therapy, atorvastatin (Lipitor), or cisplatin for cancer.
Use the medication checker on this page with your exact drugs.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help with hot flashes and other menopausal symptoms. Because it interacts with a broad range of medications — especially antidepressants, heart and blood pressure drugs, and hormonal therapies — you should check your full medication list with a pharmacist before you start.
If you're pregnant, planning pregnancy, or breastfeeding, this product isn't recommended. Talk to your pharmacist about whether it fits your situation.

For each ingredient in Blue Cohosh Root 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.
Blue Cohosh root 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.
