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.

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, presented as a powder. There are no other inactive ingredients listed.

Burdock root is a plant that's been used traditionally in herbal and food preparations. This extract form concentrates the compounds from the root.

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 support claims that burdock root works for acne, aging skin, breast cancer, common cold, or atopic dermatitis (eczema)—in each case, there isn't enough reliable research to rate it. If you're considering this product for one of these purposes, talk with your doctor or pharmacist about whether the evidence supports it 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 a food and for short-term use in healthy adults, though human safety data are limited. Serious allergic reactions—including contact dermatitis and, rarely, anaphylaxis—have been reported.

There's one case of liver damage reported in someone taking a detox tea that contained burdock along with other ingredients, though it's unclear whether burdock was responsible. Contact dermatitis has occurred with prolonged use of burdock root oil and burdock plasters, sometimes appearing up to a week after use.

Don't use medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus. Avoid it while breastfeeding because there isn't enough safety information.

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 taking this product, double-check with your doctor or pharmacist if you take any anticoagulant or antiplatelet drugs—blood thinners like warfarin or apixaban, or antiplatelet agents like clopidogrel or aspirin taken for heart protection. Burdock may theoretically increase your bleeding risk when combined with these.

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 plant extract that's generally well tolerated as a food but has limited human safety data in extract form. The main concern is a potential increase in bleeding risk with blood thinners and antiplatelet drugs.

If you take any of those medications, check with your doctor or pharmacist before starting. Those not on blood thinners and without a history of allergies to burdock or plants in its family can usually take it, but talk with your own healthcare provider about whether it makes sense for your needs.
