HelloPharmacist Scorecard of Yellow Dock 2,000 mg by Nature's Answer

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 extract at 2,000 mg per serving. Yellow dock is a plant whose root has traditionally been used as a laxative and digestive aid.

The product is delivered as a liquid in a base of purified water, vegetable glycerin, and certified organic alcohol.

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.

Our data does not include effectiveness ratings for yellow dock, so we can't tell you from the evidence we hold whether this product works for its intended purpose.

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 taken in food amounts. However, the safety data advises against use during pregnancy and while nursing — there isn't enough safety data, and because yellow dock acts as a laxative, compounds may pass into breast milk.

Consuming raw leaves or rhizomes can cause serious effects including low calcium (hypocalcemia), kidney stones, and vomiting; the product itself is an extract, so prepared properly, but older or uncooked leaves should be avoided. Large amounts can cause a skin rash, and the herb contains oxalates, which warrant caution with long-term use.

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.

Check before taking this if you use diuretics (water pills), digoxin, or warfarin. All three carry Major or Moderate risk of serious effects, including altered potassium levels and increased bleeding or heart medication toxicity.

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 may appeal to people looking for a natural laxative or digestive support, but it's a short-term remedy only. If you take diuretics, digoxin, or warfarin, you need to talk with your pharmacist before using this — the interactions are serious.

Pregnancy and breastfeeding are reasons to skip it.

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 2,000 mg by Nature's Answer: Common Questions

Does Yellow Dock 2,000 mg by Nature's Answer interact with any medications?
Yes. Based on its ingredients, Yellow Dock 2,000 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 2,000 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 use yellow dock while I'm pregnant?
No — the safety data advises against it. There isn't enough safety information, and because yellow dock acts as a laxative, the risks outweigh any benefit. Talk with your doctor or pharmacist about safer options.
Is yellow dock safe to take while nursing?
No. Laxative compounds may pass into breast milk, so it's best avoided while you're breastfeeding.
What happens if I take too much yellow dock?
Large amounts can cause diarrhea and skin rashes. Raw or uncooked leaves are unsafe and can cause low calcium, kidney stones, and vomiting. Stick to short-term use and the recommended dose.
Why does yellow dock interact with diuretics and heart medications?
Yellow dock can lower potassium levels in your body when used long-term or in large doses. Diuretics also lower potassium, so combining them raises your risk of dangerously low levels. Digoxin depends on normal potassium to work safely, so low potassium makes toxicity more likely.
Can I take this with warfarin?
Not without checking with your pharmacist first. Yellow dock's laxative effect can cause diarrhea, which strengthens warfarin's effects and raises your bleeding risk.
