HelloPharmacist Scorecard of Caulophyllum Tha. Blue Cohosh by Wise Woman Herbals

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (2 mL) without saying how much of each component you get.

This liquid contains one active ingredient: blue cohosh, a botanical traditionally used in herbal preparations. The formula also includes spring water and alcohol as inactive ingredients.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Blue Cohosh product and its label doesn't state a use — see Blue Cohosh's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

We hold no evidence data for blue cohosh's effectiveness in our records. That doesn't mean it doesn't work — it means the research backing for this ingredient isn't established in the information we have on file.

The evidence, ingredient by ingredient Blue Cohosh

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Blue cohosh carries real safety concerns. It can cause stomach upset including diarrhea and cramping, chest pain, nausea, vomiting, and irritation of mucous membranes.

More seriously, blue cohosh affects the heart and has been linked to heart attacks, heart failure, and shock in newborns whose mothers used blue cohosh during pregnancy. The safety data advises against use during pregnancy and while breastfeeding.

Side effects, ingredient by ingredient Blue Cohosh

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Blue Cohosh.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 259 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.

Check with your doctor or pharmacist if you take blood pressure medications (like captopril, enalapril, losartan, or valsartan), diabetes drugs (insulin, glimepiride, glyburide, pioglitazone, or rosiglitazone), or nicotine. Blue cohosh may reduce how well your blood pressure and diabetes drugs work, and can amplify nicotine's effects.

Does Caulophyllum Tha. Blue Cohosh by Wise Woman Herbals interact with any medications?
Yes. Based on its ingredients, Caulophyllum Tha. Blue Cohosh has a known interaction with 259 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Caulophyllum Tha. Blue Cohosh contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Is blue cohosh safe during pregnancy?
No. The safety data advises against blue cohosh in pregnancy — it may stimulate the uterus and has been linked to serious harm to newborns, including heart attacks, heart failure, and shock. Talk with your doctor or midwife if you are thinking about any herbal supplement during pregnancy.
Can I take this while breastfeeding?
There isn't enough safety information to know. The data advises against use while breastfeeding. Talk with your doctor or pharmacist about your specific situation before taking this product.
What side effects can blue cohosh cause?
Common effects include stomach upset, diarrhea, cramping, nausea, vomiting, and mouth irritation. More serious concerns are chest pain and changes in blood pressure and blood sugar. Because blue cohosh affects the heart, it carries real risk — talk with your doctor or pharmacist before starting.
Does blue cohosh actually work?
We don't have effectiveness data for blue cohosh in our records, so we can't tell you whether it's proven to work for any condition. That's a good question to ask your herbalist or healthcare provider.
Why is alcohol in this product?
Alcohol is listed as an inactive ingredient — it's used as a preservative and solvent in liquid herbal extracts. The amount per dose should be small, but if you're sensitive to alcohol or need to avoid it, check the label or talk with your pharmacist.
