HelloPharmacist Scorecard of Burdock Root by Cedar Bear

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 (0.50 mL) without saying how much of each component you get.

This product contains one active ingredient: burdock root in a liquid form. The liquid is prepared with vegetable glycerin and purified water as inactive ingredients — these are the carriers that make the burdock drinkable and shelf-stable.

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 doesn't establish that burdock works for the conditions listed — acne, aging skin, breast cancer, common cold, and eczema all carry a rating of insufficient reliable evidence. That doesn't mean burdock is ineffective; it means clinical trials strong enough to prove it haven't been done yet, or the data isn't robust enough to say either way.

If you're considering it for one of these uses, talk it over with your doctor to see whether trying it makes sense for your situation.

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 eaten as food and in short-term use by healthy adults, though thorough safety studies are limited and it has a long history of traditional use with few reported problems. Serious allergic reactions including anaphylaxis are rare but possible, and contact dermatitis has occurred — especially with prolonged skin contact or use of burdock plasters, sometimes showing up a week after application.

A single case of liver injury was reported in someone taking a multi-ingredient herbal tea containing burdock, but it's unclear whether burdock itself was responsible. The safety data advises against taking burdock in medicinal amounts during pregnancy and while breastfeeding due to lack of safety data and potential effects on the uterus.

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 take this product, double-check it with your doctor or pharmacist if you're on any blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, and similar medications) — there's a Moderate-severity interaction risk for increased bleeding, even though it hasn't been seen in actual patients yet.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Burdock root as a liquid supplement is generally well tolerated in the short term, but evidence doesn't yet establish it works for common skin or health complaints. If you're on a blood thinner or antiplatelet medication, check with your doctor or pharmacist before starting it.

Pregnant or breastfeeding people should avoid it in medicinal doses. Talk it over with your own healthcare provider to see if it fits your health goals.

Burdock Root by Cedar Bear: Common Questions

Does Burdock Root by Cedar Bear interact with any medications?
Yes. Based on its ingredients, Burdock Root 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 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 burdock safe during pregnancy or while breastfeeding?
No — the safety data advises against taking burdock in medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus, and there isn't enough safety information for breastfeeding either. If you're pregnant or nursing, talk with your doctor or pharmacist before using this product.
Can I take burdock if I'm on a blood thinner like warfarin?
That's something to check with your own doctor or pharmacist first. Lab research suggests burdock might increase bleeding risk when combined with blood thinners, though it hasn't been reported in actual patients — still a Moderate-severity concern worth clearing before you start.
Does burdock cause side effects?
When eaten as food, burdock is well tolerated. Serious allergic reactions like anaphylaxis are rare. Contact dermatitis (a rash) has occurred, especially with prolonged skin use or burdock plasters, sometimes showing up days after application. A single case of liver injury was reported with a multi-ingredient herbal tea, but it's unclear if burdock was the cause.
Does this product actually work for acne, eczema, or colds?
The evidence we hold doesn't establish that burdock works for those uses — acne, aging skin, breast cancer, common cold, and eczema all lack reliable evidence. That doesn't mean it doesn't work; it means clinical trials strong enough to prove it haven't been completed yet.
What's burdock actually for?
Burdock has a long history of traditional use and is commonly eaten as food. It's been used traditionally for skin health and general wellness, but clinical evidence supporting those uses isn't established yet in our data.
