HelloPharmacist Scorecard of Niu Bang Zi by Herbal Terra

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 Aug 27, 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: certified organic Niu Bang Zi (Arctium lappa) — also known as burdock — in the form of a dried seed liquid extract. Burdock is a root vegetable with a long history in herbal traditions.

The liquid extract form means the active compounds from the seeds have been concentrated and dissolved into a preparation you can take by mouth.

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 we hold on burdock for common uses — acne, aging skin, breast cancer, common cold, and eczema — is insufficient to establish whether it works. That doesn't mean it doesn't; it means the scientific data we have isn't strong enough to say either way.

If you're considering this for a specific condition, talk with your doctor or pharmacist about what the current evidence supports.

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.

When burdock is eaten as a food, it's well tolerated, and it has a long history of use with few reported side effects. For medicinal use, though, human safety data are limited, so caution is warranted.

Serious allergic reactions are rare but possible, including contact dermatitis (a rash from skin contact) and, very rarely, anaphylaxis. A single case of liver injury has been reported in someone taking a multi-ingredient herbal tea that contained burdock; it's unclear whether burdock was responsible.

Contact dermatitis has also occurred with prolonged use of burdock root oil or plasters, sometimes appearing days after application. Because safety data in pregnancy are lacking and there's a possibility of effects on the uterus, avoid medicinal amounts of burdock if you're pregnant.

There isn't enough safety information to recommend it during breastfeeding either. Talk with your doctor or pharmacist about these concerns before taking this product if you're pregnant, planning to become pregnant, or breastfeeding.

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.

Before you start Niu Bang Zi, double-check any blood thinners (anticoagulants) or antiplatelet drugs you're on — such as warfarin, dabigatran, rivaroxaban, aspirin, clopidogrel, or ticagrelor. Lab evidence suggests burdock may thin the blood further, though this hasn't been reported in humans.

Clear it with your doctor or pharmacist first.

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.

Niu Bang Zi is generally well tolerated when used short-term, but the evidence for its effectiveness for common conditions isn't established in our data. If you take blood thinners or antiplatelet medications, check with your doctor or pharmacist first — the interaction is theoretical but documented in lab research.

Pregnant and breastfeeding people should avoid it. It's worth a conversation with your own healthcare provider about whether this is right for you.

Niu Bang Zi by Herbal Terra: Common Questions

Does Niu Bang Zi by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Niu Bang Zi 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?
Niu Bang Zi 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 use this if I'm pregnant or breastfeeding?
No. The safety data advise against medicinal amounts of burdock in pregnancy because of potential effects on the uterus, and there isn't enough information to recommend it while breastfeeding. Talk with your doctor or pharmacist for personalized guidance.
What's burdock, and what is it supposed to do?
Burdock (Arctium lappa) is a root vegetable with a long history in herbal use. This product is a liquid extract of the dried seeds. The evidence we have isn't strong enough to say whether it works for acne, aging skin, breast cancer, cold, or eczema, so we can't make a claim about what it does.
What are the side effects?
When burdock is eaten as food, it's well tolerated. Serious side effects are rare but can include allergic reactions — contact dermatitis (a rash) and very rarely anaphylaxis. A single case of liver injury was reported with a multi-ingredient tea containing burdock, though it's unclear if burdock was the cause. Contact dermatitis has occurred with prolonged use of burdock root oil or plasters, sometimes days after use starts.
Is this safe for long-term use?
Burdock is likely safe for short-term use in healthy adults, but human safety data for long-term use are limited. If you're thinking about using it regularly, talk with your doctor or pharmacist first.
Can I take this with blood thinners?
Lab research shows burdock may reduce platelet clumping, which theoretically could increase bleeding risk with blood thinners or antiplatelet drugs. This hasn't been reported in humans, but it's important enough to check with your doctor or pharmacist before combining them.
