HelloPharmacist Scorecard of Yellow Dock by New Sun

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 Oct 1, 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.

Yellow Dock contains one active ingredient: yellow dock root, a plant traditionally used as a mild laxative. The capsule itself includes gelatin as an inactive binder.

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 hold don't include effectiveness ratings for yellow dock, so the evidence base for this ingredient isn't established in our data.

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 in food amounts when properly prepared, but it comes with real cautions. Raw leaves or rhizomes can cause serious problems — low blood calcium (hypocalcemia), kidney stones, and vomiting — and very large amounts have been linked to breathing problems.

The root contains oxalates and acts as a laxative, so use it short-term and with care. During pregnancy, safety data suggests avoiding it — there isn't enough information to know it's safe.

While nursing, laxative compounds can pass into breast milk, so avoid use during lactation. Talk with your doctor or pharmacist about whether this is right for your situation.

Side effects, ingredient by ingredient Yellow Dock

Meds to double-check

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.

Check before taking this if you're on diuretics (water pills) — yellow dock can lower your potassium dangerously. If you take digoxin for your heart, that same potassium drop raises the risk of toxicity.

Warfarin (a blood thinner) is another Major concern because yellow dock's laxative effect can increase bleeding risk. Run your exact medications through the search tool on this page to be sure.

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 someone looking for short-term digestive support, but it's not a grab-and-go supplement. If you're on any heart or blood-pressure medication — especially diuretics, digoxin, or warfarin — you need to check with your own doctor or pharmacist first.

The same goes for pregnancy and breastfeeding. Keep the dose modest and use it briefly.

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 by New Sun: Common Questions

Does Yellow Dock by New Sun interact with any medications?
Yes. Based on its ingredients, 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?
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 while I'm pregnant?
The safety data advises against it — yellow dock is rated possibly unsafe in pregnancy. There isn't enough information to know either way for certain, so talk with your doctor or pharmacist before taking it.
Is it safe to use while breastfeeding?
No — the laxative compounds in yellow dock can pass into breast milk, so avoid it while nursing. Talk with your pharmacist or doctor about other options.
What happens if I eat the raw plant instead of the capsule?
Raw yellow dock leaves or rhizomes are unsafe. They can cause low blood calcium, kidney stones, vomiting, and in very large amounts, serious breathing problems. Use only properly prepared forms, and avoid old or uncooked leaves.
Can I take this long-term?
No — yellow dock is best used short-term. The safety notes caution against chronic use because it can build up side effects, especially low potassium, and it contains compounds that can cause problems with long-term exposure.
What does yellow dock actually do?
Yellow dock acts as a mild laxative — it has compounds that stimulate bowel movements. The product facts don't include effectiveness ratings, so we don't have evidence data on it in our system.
Will it cause a rash or skin reaction?
In large amounts, yellow dock can cause dermatitis (a skin rash). If you're sensitive to the plant, even touching it topically can trigger a reaction in some people.
