HelloPharmacist Scorecard of Butterbur Extract Powder 150 mg by BulkSupplements.com

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 11, 2026

What’s inside

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: butterbur whole herb extract at 150 mg per serving. Butterbur is a plant used in herbal medicine, and this extract is formulated to be pyrrolizidine alkaloid (PA) free—an important detail, since raw butterbur can damage the liver.

The powder also contains maltodextrin, an inactive ingredient used as a filler to make it easier to mix and measure.

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

This product doesn't appear to be marketed for a specific use, so we graded Butterbur's overall clinical evidence instead.

Moderate

Some clinical evidence supports Butterbur for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Allergic rhinitis (hay fever) — rated "Possibly Effective" (Natural Medicines).
  • On file: Migraine headache — rated "Possibly Effective" (Natural Medicines).

The evidence we hold shows butterbur extract is possibly effective for two uses: migraine headache prevention and allergic rhinitis (hay fever). That means there's some research supporting its use for these conditions, but the evidence isn't conclusive.

If you're considering it for migraine or allergy relief, talk with your pharmacist or doctor about whether the current research matches your situation.

The evidence, ingredient by ingredient Butterbur

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.

Butterbur is generally well tolerated, and most people who take it don't report serious side effects. The most common ones you might notice are belching, diarrhea, drowsiness, fatigue, headache, itchy eyes, rash, or stomach upset.

Serious liver damage from pyrrolizidine alkaloids is rare but possible; this is why the safety notes emphasize using only PA-free standardized products like this one. The product label advises against use during pregnancy—there isn't enough safety data, and the risks to a developing baby are unclear.

Breastfeeding is also not recommended because we don't have enough information on whether it passes into breast milk or what effects it might have on an infant. If you're pregnant, planning pregnancy, or nursing, talk with your doctor before starting.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Butterbur.

Theoretically, CYP3A4 inducers might increase the toxicity of butterbur.

Butterbur Extract Powder 150 mg by BulkSupplements.com: Common Questions

Does Butterbur Extract Powder 150 mg by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Butterbur Extract Powder 150 mg has a known interaction with 87 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Butterbur Extract Powder 150 mg 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 this butterbur product safe for my liver?
This product is formulated to be free of pyrrolizidine alkaloids (PAs), which are the compounds that can damage the liver. As long as you use a PA-free standardized product like this one, the liver risk is much lower. That said, there are rare reports of liver injury even with PA-free products, so if you have liver disease or concerns, mention it to your pharmacist.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advises against butterbur during pregnancy because the risks aren't well understood. It's also best to avoid while breastfeeding. If you're pregnant, planning pregnancy, or nursing, talk with your doctor before taking any supplement.
What side effects should I watch for?
Most people tolerate it well. Common side effects include belching, diarrhea, drowsiness, fatigue, headache, itchy eyes, rash, or stomach upset. Serious effects are rare. If you notice anything unusual or liver symptoms like yellowing of skin or eyes, stop and tell your pharmacist right away.
Does this really work for migraines or allergies?
The research shows butterbur is possibly effective for both migraine headache prevention and hay fever (allergic rhinitis), which means there's some good evidence behind it—but it's not a sure thing. Your results may vary, and it works best as part of a broader plan with your doctor.
What's maltodextrin in the inactive ingredients list?
That's a filler—a powder that helps the extract mix smoothly and stay stable. It's not an active ingredient; it just makes the product easier to use.
