HelloPharmacist Scorecard of Burdock Root 430 mg by NOW

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 supplement contains one active ingredient: burdock root at 430 mg per capsule. Burdock is a plant root that's been used historically as both a food and herbal remedy.

The capsule itself is made with hypromellose (a plant-based capsule material) and stearic acid (a binding agent).

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 Burdock product and its label doesn't state a use — see Burdock'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.

The evidence for burdock isn't established yet. The data we hold shows insufficient reliable evidence to rate its use for acne, aging skin, breast cancer, common cold, and atopic dermatitis (eczema).

That doesn't mean it doesn't work — it means the clinical trials aren't robust enough yet to say either way.

The evidence, ingredient by ingredient Burdock

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.

Burdock is generally well tolerated when used as food or in the short term by healthy adults, though human safety data are limited. Serious adverse effects are rare, but allergic reactions including contact dermatitis and anaphylaxis have been reported.

One case of liver inflammation occurred in someone taking a multi-ingredient detox tea containing burdock, though it's unclear whether burdock or another ingredient caused it. Contact dermatitis, especially from burdock root oil or plasters, has been documented and can appear up to a week after use.

Don't use medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus. Avoid medicinal use while breastfeeding — there isn't enough safety information.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your pharmacist or doctor before taking this.

Side effects, ingredient by ingredient Burdock

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 — Burdock.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 122 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 your exact blood thinners and antiplatelet drugs before starting — these include aspirin, warfarin, clopidogrel, apixaban, and others. Burdock may theoretically increase bleeding risk with these medications, though no human cases have been reported.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Burdock root is a traditional herbal remedy that's generally well tolerated, though the evidence for specific health claims isn't established yet. The main caution is a Moderate interaction with blood thinners and antiplatelet drugs.

If you take any of those medications or have a history of allergies to plants in the daisy family, check with your pharmacist first.

Does Burdock Root 430 mg by NOW interact with any medications?
Yes. Based on its ingredients, Burdock Root 430 mg has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Burdock Root 430 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.
Can I take this if I'm on aspirin or another blood thinner?
Not without checking first. Burdock has a documented Moderate interaction with blood thinners and antiplatelet drugs — there's a theoretical risk of increased bleeding. Use the interaction checker on this page with your exact medications, or talk to your pharmacist before starting.
Is burdock safe during pregnancy or breastfeeding?
No. Avoid medicinal amounts during pregnancy because of lack of safety data and possible effects on the uterus. Also avoid while breastfeeding — there isn't enough safety information. Talk with your doctor or pharmacist for personalized advice.
What's burdock actually used for?
Historically it's been used for acne, aging skin, breast cancer, common cold, and eczema, but the evidence we hold shows insufficient reliable evidence to rate it for any of these uses. That means the clinical studies aren't strong enough yet to confirm it works.
Will this give me side effects?
Most people tolerate burdock well, especially when used short-term. Serious reactions are rare, but allergic responses including contact dermatitis and anaphylaxis have been reported. One case of liver inflammation was reported in someone taking a multi-ingredient detox tea containing burdock, though it's unclear whether burdock caused it.
What's in the capsule besides the burdock root?
The capsule itself is made of hypromellose, a plant-based material, and the contents are bound with stearic acid. There are no artificial fillers or unnecessary extras.
