HelloPharmacist Scorecard of Burdock by Oregon's Wild Harvest

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

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 root. Burdock is a plant root traditionally used in herbal and food preparations, and this capsule delivers it in concentrated form.

The only other ingredient is pullulan, an inactive component used to make the capsule itself.

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's effectiveness isn't established in the data we hold. The product is marketed for acne, aging skin, breast cancer, common cold, and eczema, but research data we have rates all of these as having insufficient reliable evidence.

That doesn't mean burdock doesn't work—it means solid human trials haven't been published yet, or published data are too limited to draw a firm conclusion. If you're considering it for one of these uses, talk with your doctor or pharmacist about what the current science actually 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.

Burdock is generally well tolerated when eaten as food, and has a long history of traditional use with few reported problems. As a medicinal supplement, though, human safety data are limited.

Rare allergic reactions—including contact dermatitis and, very rarely, anaphylaxis—have been reported. A single case of liver injury was reported in someone taking a multi-ingredient herbal tea that contained burdock, but it's unclear whether burdock was the cause.

Contact dermatitis can occur with prolonged use of burdock root oil or burdock plasters, sometimes within days of starting. You should avoid medicinal amounts of burdock during pregnancy because safety data are lacking and it may affect the uterus.

Don't use medicinal amounts while breastfeeding either—there isn't enough safety information. If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking any supplement.

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 or antiplatelet drugs—like warfarin, aspirin, or clopidogrel—double-check with your pharmacist or doctor before using this product. The interaction is rated Moderate and relates to a potential increase in bleeding risk.

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 is generally well tolerated as food and for short-term use in healthy adults, but the evidence for its effectiveness at the doses used in supplements hasn't been firmly established yet. The main caution is with blood thinners and antiplatelet drugs—check your medications first.

Avoid it during pregnancy and breastfeeding. Talk with your doctor or pharmacist before starting, especially if you take any prescription medications.

Burdock by Oregon's Wild Harvest: Common Questions

Does Burdock by Oregon's Wild Harvest interact with any medications?
Yes. Based on its ingredients, Burdock 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 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?
No. The safety data aren't there to say it's okay during pregnancy—and it may affect the uterus—so you should avoid medicinal amounts. The same goes for breastfeeding. Talk with your doctor or pharmacist about whether burdock is right for you if you're pregnant, planning to become pregnant, or nursing.
What are the side effects?
When eaten as food, burdock causes few or no side effects. Allergic reactions are rare but possible, including contact dermatitis (a skin rash) and very rarely anaphylaxis. Prolonged use of burdock root oil or burdock plasters can cause contact dermatitis in sensitive people, sometimes within days. A single case of liver injury was reported, but it's unclear if burdock was responsible.
Does burdock actually work for acne, eczema, or the common cold?
We don't have solid evidence yet. The research we hold rates burdock as having insufficient reliable evidence for acne, aging skin, breast cancer, common cold, and eczema. That means human trials are either missing or too limited to draw firm conclusions—not that it doesn't work, just that we can't prove it yet. Ask your doctor what the latest research says for your specific use.
What is burdock and why is it in this supplement?
Burdock is a plant root with a long history in traditional herbal medicine and as a food. It's used in supplements because of traditional beliefs about its benefits for skin, immunity, and general health, though clinical evidence is still limited.
Are there any fillers or additives I should know about?
This capsule contains burdock and pullulan—which is the material the capsule itself is made from. There are no other inactive ingredients listed.
Can I take this with my blood thinner?
Not without checking first. Burdock may increase bleeding risk if you take warfarin, aspirin, clopidogrel, or similar drugs. Use the medication search tool on this page to check your exact medication, and then talk with your pharmacist or doctor before starting burdock.
