HelloPharmacist Scorecard of Niu Bang Zi by Hawaii Pharm

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: burdock seed extract (from Arctium lappa). It's a traditional botanical used in herbal medicine, typically prepared here as a liquid extract for easier dosing.

The product also includes alcohol, water, and glycerin as inactive ingredients—these are the carrier and preservative base that make it a liquid.

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 for the conditions listed in our data. Acne, aging skin, breast cancer, common cold, and atopic dermatitis (eczema) all show insufficient reliable evidence to rate how well burdock works for them.

That doesn't mean it doesn't help—it means the research so far hasn't been rigorous enough to say one way or the other.

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 you eat it as food, and it has a long history of use with few reported adverse effects. However, human safety data for medicinal use are limited.

Rare serious allergic reactions—including contact dermatitis and anaphylaxis—have been reported. There's also one reported case of drug-induced liver injury in someone taking an herbal tea with burdock and other ingredients, though it's unclear whether burdock was the culprit.

Contact dermatitis has occurred with prolonged use of burdock root oil or plasters, sometimes days after application. Avoid medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus.

Don't use medicinal amounts while breastfeeding—there isn't enough safety information. Talk with your doctor or pharmacist if you're pregnant, breastfeeding, or planning to be.

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.

If you take blood thinners (anticoagulants) or antiplatelet drugs like warfarin, aspirin, or clopidogrel, double-check with your doctor or pharmacist before using this product—burdock may theoretically increase bleeding risk. No other medication interactions are documented for the ingredient we checked.

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 has a long folk history and is generally well tolerated as food, but medicinal evidence for the conditions listed isn't established yet. The main concern is a possible increase in bleeding risk if you take blood thinners or antiplatelet drugs.

If you're on those medications, or if you have liver concerns or a history of allergic skin reactions, check with your doctor or pharmacist before starting this product.

Niu Bang Zi by Hawaii Pharm: Common Questions

Does Niu Bang Zi by Hawaii Pharm 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 take this while I'm pregnant or breastfeeding?
Not in medicinal amounts. Safety data are lacking and burdock may affect the uterus during pregnancy. While breastfeeding, there isn't enough information to know if it's safe. Talk with your doctor or pharmacist about whether this is right for you.
Does burdock actually work for acne or eczema?
The evidence isn't established in the data we have. That means research so far hasn't been rigorous enough to say whether it helps these conditions. You might look for other options with clearer evidence, or talk with your doctor about what the science actually supports.
What are the side effects?
When eaten as food, burdock is well tolerated with few reported problems. Rare serious allergic reactions like anaphylaxis can happen. Contact dermatitis (an itchy, red rash) has occurred with prolonged use of burdock root oil or plasters, sometimes days after you start. One case of liver injury was reported, though other ingredients may have been involved.
Is this safe for long-term use?
Burdock is considered likely safe for short-term use in healthy adults, but human safety data for long-term medicinal use are limited. If you're thinking about using it regularly, check with your doctor or pharmacist.
What is burdock and what does it do?
Burdock is a root plant used in traditional herbal medicine. This product is made from the seed extract. It's been used historically with few reported problems, but the evidence for specific health conditions—like acne or eczema—isn't established yet.
What's in this liquid besides the burdock?
The product contains alcohol, water, and glycerin as inactive ingredients. These make it a liquid extract and help preserve it.
