HelloPharmacist Scorecard of Rumex Cri. Yellow Dock by Wise Woman Herbals

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 Sep 10, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (2.50 mL) without saying how much of each component you get.

This product contains one active ingredient: yellow dock, a plant whose roots and leaves have been used traditionally. Yellow dock acts as a mild stimulant laxative and contains compounds called anthraquinones and oxalates.

The liquid also holds inactive ingredients — spring water, alcohol, and glycerin — that serve as the base and preservative.

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.

We don't have effectiveness data on file for yellow dock in our facts.

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 appears well tolerated when properly prepared and taken in food amounts. However, the safety data advises against use during pregnancy and while breastfeeding — laxative compounds may pass into breast milk, and there isn't enough safety information to recommend it in pregnancy.

Raw leaves or rhizomes can be unsafe and may cause low blood calcium, kidney stones, and vomiting; older or uncooked leaves should be avoided. Very high doses (500 grams or more) have been linked to serious lung and respiratory effects.

Because yellow dock acts as a laxative and contains oxalates, the manufacturer advises short-term use only and with care.

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, check with your doctor or pharmacist if you use a water pill (diuretic) — yellow dock may lower potassium dangerously. The same caution applies if you take digoxin for your heart, or if you take warfarin to thin your blood.

The laxative effect can raise the risk of bleeding with warfarin.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Yellow dock is a traditional laxative herb that's generally well tolerated at food doses when properly prepared. If you take a diuretic, digoxin, warfarin, or any other regular medication, talk with your doctor or pharmacist before adding this product — the interactions are serious.

Avoid it if you're pregnant or nursing. It's meant for short-term use.

Warfarin (Coumadin)

Rumex Cri. Yellow Dock by Wise Woman Herbals: Common Questions

Does Rumex Cri. Yellow Dock by Wise Woman Herbals interact with any medications?
Yes. Based on its ingredients, Rumex Cri. Yellow Dock 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?
Rumex Cri. Yellow Dock 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 Yellow Dock if I'm pregnant or breastfeeding?
No, the safety data advises against it. There isn't enough safety information in pregnancy, and laxative compounds may pass into breast milk. Talk with your doctor or pharmacist before considering it.
Is Yellow Dock safe to use long-term?
The manufacturer advises short-term use only with care. Yellow dock contains oxalates and acts as a laxative, so it's not intended for ongoing daily use.
What are the side effects of Yellow Dock?
When properly prepared and taken in food amounts, yellow dock is generally well tolerated. Raw leaves or rhizomes, however, can cause low blood calcium, kidney stones, and vomiting. Very high doses have been linked to serious respiratory effects, so avoid older or uncooked leaves.
What does Yellow Dock do?
Yellow dock acts as a mild stimulant laxative through compounds called anthraquinones. It's been used traditionally to support digestion, though we don't have effectiveness data for it in our facts.
Why can't I take Yellow Dock with my water pill or heart medication?
Yellow dock can lower potassium levels when used long-term or in large amounts. If you're on a diuretic (water pill), this compounds the drug's own potassium-lowering effect. If you take digoxin for your heart, low potassium raises the risk of serious heart toxicity.
