HelloPharmacist Scorecard of Black Cohosh Extract Plus by Meijer Naturals

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.

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Black Cohosh Extract Plus contains three active herbal ingredients. Black cohosh root extract is included to support menopausal symptoms, for which it's considered possibly effective.

Chasteberry fruit powder is added for premenstrual syndrome and breast tenderness — both rated possibly effective. Dong quai root powder rounds out the formula, though we don't have enough evidence on file to rate its effectiveness for the conditions it's traditionally used for.

The product is made with gelatin capsules.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: helps keep woman's natural hormones in healthy balance.
  • We looked for evidence on: Menopausal symptoms, Premenstrual syndrome (PMS), Dysmenorrhea, Amenorrhea, Mastalgia, Premenstrual dysphoric disorder (PMDD) — and 4 related terms.
  • The strongest evidence on file: Black Cohosh is rated "Possibly Effective" for Menopausal symptoms (Natural Medicines).
  • Also on file: Vitex Agnus-castus is rated "Possibly Effective" for Mastalgia, Premenstrual syndrome (PMS).
  • Also on file: Black Cohosh is rated "Insufficient Reliable Evidence To Rate" for Breast cancer-related hot flashes, Premenstrual syndrome (PMS), Dysmenorrhea.

Black cohosh is possibly effective for menopausal symptoms based on available evidence. Chasteberry is possibly effective for premenstrual syndrome and breast tenderness.

For the other uses these herbs are sometimes marketed for — including acne, anxiety, sexual dysfunction (black cohosh), and bone health or migraine relief (dong quai) — we don't have enough reliable evidence to establish whether they work. If menopausal symptoms or PMS relief is what you're after, there's a reasonable foundation.

For other conditions, the evidence just isn't there yet.

The evidence, ingredient by ingredient Black Cohosh Vitex Agnus-castus Dong Quai

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Black cohosh and chasteberry are generally well tolerated in the short term, though both may affect hormones and warrant guidance from a doctor or pharmacist. The most common side effects you might notice are mild: black cohosh may cause breast tenderness, dizziness, headache, tiredness, or stomach upset.

Chasteberry may cause diarrhea, fatigue, headache, nausea, or irregular periods. Dong quai is generally well tolerated but may cause burping or flatulence, and it can make your skin more sensitive to sunlight.

Rare but serious concerns include liver damage with black cohosh and increased bleeding risk with dong quai. Pregnancy and breastfeeding: black cohosh and chasteberry both lack enough safety data and may affect the uterus or hormones, so they're best avoided while pregnant or nursing.

Dong quai safety data while breastfeeding is incomplete, so it's best avoided too.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Black Cohosh, Dong Quai, Vitex Agnus-castus.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 798 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this product, double-check if you use warfarin (Coumadin) or other blood thinners — dong quai significantly increases bleeding risk. Also flag estrogens and hormone therapy, birth control pills, antidepressants (especially serotonergic ones like sertraline or duloxetine), antipsychotics, dopamine agonists, metoclopramide (Reglan), and any drugs that stress the liver.

Black cohosh may slow how your liver clears many medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product may help with menopausal symptoms and premenstrual syndrome if you're not taking medications that interact with it. If you're on warfarin or other blood thinners, birth control, hormone therapy, antidepressants, antipsychotics, or any medication metabolized by your liver, talk to your pharmacist before starting — the interaction list is long.

Black Cohosh Root Extract7 drug types · 652 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
Black Cohosh Root Extract full monograph & interactions

Dong Quai root powder3 drug types · 163 drugs

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Likelihood Possible Evidence D

Chasteberry fruit powder5 drug types · 121 drugs

Antipsychotic Drugs

Theoretically, vitex agnus-castus could interfere with the activity of antipsychotic drugs.
Vitex agnus-castus might interfere with the action of dopamine antagonists such as antipsychotic drugs due to its dopamine agonist effects.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, vitex agnus-castus could interfere with oral contraceptives.
Vitex agnus-castus might interfere with the efficacy of oral contraceptives due to possible hormone modulating activity.

Likelihood Possible Evidence B
Dopamine Agonists

Theoretically, vitex agnus-castus could interfere with dopamine agonists.
Vitex agnus-castus might potentiate the actions of dopaminergic agonists due to possible dopaminergic effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, vitex agnus-castus could interfere with the activity of estrogens.
Vitex agnus-castus has hormone modulating activity that can interfere with the efficacy of hormone replacement therapy.

Likelihood Probable Evidence D
Metoclopramide (Reglan)

Theoretically, dopaminergic effects of vitex agnus-castus could interfere with metoclopramide.
Vitex agnus-castus might interfere with the action of dopamine antagonists such as metoclopramide due to its possible dopaminergic effects.

Black Cohosh Extract Plus by Meijer Naturals: Common Questions

Does Black Cohosh Extract Plus by Meijer Naturals interact with any medications?
Yes. Based on its ingredients, Black Cohosh Extract Plus has a known interaction with 797 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Black Cohosh Extract Plus contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this help with my hot flashes?
Black cohosh is possibly effective for menopausal symptoms like hot flashes based on available evidence. It's worth a try, but results vary from person to person. Check your medications first — especially if you're on hormone therapy or estrogen.
Can I take this if I'm on birth control?
Not without talking to your doctor or pharmacist first. Chasteberry may interfere with how oral contraceptives work, which could reduce their effectiveness. You'll want personalized advice before starting.
Is it safe to take while I'm breastfeeding?
No. Both black cohosh and chasteberry lack enough safety data for breastfeeding and may affect milk-related hormones. Dong quai's safety information while breastfeeding is also incomplete. It's best avoided.
What are the most common side effects?
Black cohosh users most often report breast tenderness, dizziness, headache, tiredness, or stomach upset. Chasteberry may cause diarrhea, fatigue, headache, nausea, or irregular periods. Dong quai typically causes burping or flatulence.
I'm on an antidepressant. Is this product safe for me?
Not without checking first. Black cohosh may increase serotonin syndrome risk when combined with certain antidepressants, and it can also slow how your liver clears some of these drugs. Talk to your pharmacist before you start.
Can I take this with my blood thinner?
Probably not — dong quai in this product increases bleeding risk with blood thinners like warfarin (Coumadin), and it may do the same with other anticoagulants. Don't start without your doctor's approval.
