HelloPharmacist Scorecard of Yellow Dock Root 1,000 mg by Nature's Way

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 11, 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: yellow dock root at 1,000 mg per capsule. Yellow dock is a plant traditionally used as a mild laxative.

The capsule itself is made from plant-derived material, and the formula includes magnesium stearate and silica as inactive ingredients.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Traditional digestive support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't have effectiveness ratings in our data for yellow dock root, so we can't tell you how well it works for any particular condition. If you're thinking about using it, talk with your pharmacist or doctor about what the evidence shows for your specific 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 properly prepared and used in food amounts for a short time. However, the safety notes flag that it acts as a laxative and contains oxalates—compounds that can build up in the body—so it's meant for short-term use and should be used with care.

Raw leaves or rhizomes can be unsafe and may cause low blood calcium (hypocalcemia), kidney stones, and vomiting. The supplement should not be used during pregnancy or while breastfeeding, as there isn't enough safety data and the laxative compounds may pass into breast milk.

Meds to double-check

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) or digoxin (a heart medication)—both carry Major-severity interaction risks involving low potassium. Warfarin (a blood thinner) also interacts at Moderate severity through increased bleeding risk.

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.

Yellow Dock Root is best considered only for short-term use and only if you don't take a diuretic, digoxin, or warfarin. If you're on any of those or other regular medications, check with your pharmacist first—the interaction risks are real.

Yellow Dock3 drug types · 78 drugs

Digoxin (Lanoxin)

Theoretically, yellow dock might increase the risk of digoxin toxicity when used long-term or in large amount.
When yellow dock is used chronically or in large amounts, hypokalemia may occur. This might increase the toxic effects of digoxin.

Likelihood Probable Evidence D
Diuretic Drugs

Theoretically, yellow dock might increase the risk of hypokalemia when taken with diuretics.
When yellow dock is used chronically or in large amounts, hypokalemia may occur, and overuse of yellow dock might compound diuretic-induced potassium loss.

Likelihood Probable Evidence D
Warfarin (Coumadin)

Theoretically, the laxative effects of yellow dock might increase the effects of warfarin, including the risk of bleeding.
The anthraquinones in yellow dock have a mild stimulant laxative effect. Consuming excessive amounts can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding.

Yellow Dock Root 1,000 mg by Nature's Way: Common Questions

Does Yellow Dock Root 1,000 mg by Nature's Way interact with any medications?
Yes. Based on its ingredients, Yellow Dock Root 1,000 mg 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 Root 1,000 mg 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?
No—the safety data advises against it. There isn't enough safety information during pregnancy, and the laxative compounds in yellow dock may pass into breast milk, so it's best avoided while nursing. Talk with your doctor if you're considering it.
What are the side effects?
When properly prepared and used short-term, yellow dock is generally well tolerated. Raw leaves or rhizomes can cause serious problems like low blood calcium, kidney stones, and vomiting, so avoid those forms. In large amounts, it may cause a skin rash. It also acts as a laxative, so diarrhea is possible.
How long can I take this?
The safety data recommends short-term use only. It's not meant to be a long-term supplement because of its laxative effect and oxalate content. Talk with your pharmacist about what 'short-term' means for your situation.
Why does it matter that yellow dock is a laxative?
The laxative effect can increase how warfarin (a blood thinner) works in your body, raising your bleeding risk. It also triggers the potassium loss problem with diuretics and digoxin. That's why dose and duration matter so much with this one.
What is yellow dock used for?
Yellow dock is traditionally used as a mild laxative to support digestion. We don't have effectiveness ratings for it in our data, so if you want to know how well it works for a specific condition, ask your pharmacist.
