HelloPharmacist Scorecard of Extra Strength Burdock Root 4:1 Extract Powder by TerraVita Premium Collection

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 30, 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 extract in a 4:1 concentration (meaning four parts raw root are condensed into one part extract), which makes it more concentrated than the whole plant. Burdock root has a long history of use in traditional herbal practice.

The product has no inactive ingredients listed.

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 on burdock for the conditions listed — acne, aging skin, breast cancer, common cold, and eczema — is not yet established. Our data shows insufficient reliable evidence to rate it for any of these uses.

That doesn't mean it won't help, only that rigorous human studies are lacking.

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 or used short-term by healthy adults, though human safety data are limited. The main concern is that serious allergic reactions, including contact dermatitis and anaphylaxis, are rare but possible — and contact dermatitis has been reported, especially with prolonged use of burdock root oil or plasters.

A single case of liver injury was reported in someone taking a multi-ingredient detox tea containing burdock, but it's unclear whether burdock itself was responsible. During pregnancy, medicinal amounts of burdock are not advised due to lack of safety data and possible effects on the uterus.

While breastfeeding, there isn't enough information to know whether this dose is safe, so talk with your doctor or pharmacist before using it.

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're on anticoagulant or antiplatelet drugs — such as warfarin, clopidogrel, aspirin, or other blood thinners — double-check with your doctor or pharmacist before taking this product. The interaction is Moderate in severity and centers on a possible 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 root is a traditional remedy with a long history of use and few reported side effects in food amounts, but human research on its effectiveness for skin, cancer, or cold symptoms is sparse. If you take blood thinners or antiplatelet drugs, check with your doctor or pharmacist before starting — the interaction is theoretical but plausible.

Otherwise, have your healthcare provider review this alongside any medications you're on.
