HelloPharmacist Scorecard of Yellow Dock Alcohol Free by Herbal Terra

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: yellow dock root extract, dried. Yellow dock is a plant traditionally used for its laxative properties.

The liquid form also contains glycerin and water as inactive ingredients to make it drinkable.

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 Yellow Dock product and its label doesn't state a use — see Yellow Dock'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 product facts we have don't include effectiveness ratings for yellow dock root extract for any particular condition. We'd recommend asking your pharmacist what you're hoping this product will do—they can tell you whether the evidence supports that use.

The evidence, ingredient by ingredient Yellow Dock

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.

Yellow dock is generally well tolerated when used in food amounts and properly prepared, though it does act as a laxative. The safety data advises against it during pregnancy and while nursing because of insufficient safety data and its laxative effect.

Consuming raw yellow dock leaves or rhizomes may be unsafe—they're linked to low blood calcium (hypocalcemia), kidney stones, and vomiting. In rare cases, very large amounts (500 grams or more) have been linked to serious lung effects.

The product also contains oxalates, which is why short-term use and caution are advised.

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Yellow Dock.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 78 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 if you're on diuretics (water pills), digoxin (Lanoxin) for your heart, or warfarin (Coumadin) or other blood thinners. These carry Major or Moderate interaction risks with yellow dock.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

If you're taking diuretics, digoxin, warfarin, or other blood thinners, this isn't something to start without talking to your pharmacist first. Pregnant or nursing?

The safety data suggests you should avoid it. For anyone else considering it, keep use short-term and at modest amounts—check your medications below before you begin.

Yellow Dock Alcohol Free by Herbal Terra: Common Questions

Does Yellow Dock Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Yellow Dock Alcohol Free has a known interaction with 78 medications, including 76 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Yellow Dock Alcohol Free 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 if I'm pregnant or breastfeeding?
The safety data advises against it during pregnancy because there isn't enough safety information and it has a laxative effect. The same goes for nursing—laxative compounds may pass into breast milk. Talk with your pharmacist or doctor for personalized advice.
What does yellow dock actually do?
Yellow dock root is traditionally used for its laxative properties—it mildly stimulates bowel movement. The facts we have don't include evidence ratings for any specific health condition, so ask your pharmacist what you're hoping to achieve with it.
Is this safe to take every day?
The safety data recommends short-term use and caution. Yellow dock can cause low potassium when used chronically or in large amounts, which is a real concern if you take certain heart or blood pressure medications. Keep use short-term and check with your pharmacist about your specific situation.
What are the side effects?
When properly prepared and used in food amounts, yellow dock is well tolerated. Raw leaves or rhizomes are unsafe and can cause low blood calcium, kidney stones, and vomiting. Very large amounts have rarely caused serious lung effects. Large doses can also cause a skin rash in some people.
Why does the label mention oxalates?
Oxalates are natural compounds in yellow dock. In your body, they can bind to calcium and form kidney stones or cause low blood calcium, especially with raw or uncooked plant material. That's why proper preparation and short-term use matter.
Does this product have any fillers?
It contains glycerin and water as inactive ingredients to make the liquid drinkable. Those are the only other ingredients besides the active yellow dock root extract.
