HelloPharmacist Scorecard of Yellow Dock (Rumex crispus) Root by TerraVita

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 glycerite liquid extract. The extract is suspended in glycerin, an inactive ingredient that acts as the carrier liquid.

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 hold effectiveness ratings for yellow dock in our data, so we can't tell you whether it works for any particular use. If you're considering it for a specific health goal, ask your pharmacist what the evidence shows.

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 seems well tolerated when prepared properly and used in food amounts, but it does act as a laxative and contains oxalates that you should be aware of. The safety data advises against use during pregnancy and breastfeeding because of laxative compounds and insufficient safety information.

Raw or uncooked leaves are unsafe — they've been linked to low blood calcium (hypocalcemia), kidney stones, and vomiting. Very large amounts (500 grams or more) have been associated with serious effects including respiratory depression.

Long-term or excessive use can also cause skin irritation in some people.

  • 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 with your pharmacist if you're on a diuretic (water pill), digoxin (Lanoxin) for your heart, or warfarin (Coumadin) as a blood thinner. These carry the most serious documented interactions.

Yellow Dock (Rumex crispus) Root by TerraVita: Common Questions

Does Yellow Dock (Rumex crispus) Root by TerraVita interact with any medications?
Yes. Based on its ingredients, Yellow Dock (Rumex crispus) Root 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 (Rumex crispus) Root 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.
Is yellow dock safe to use long-term?
No — the safety data recommends short-term use with care. Yellow dock acts as a laxative and contains oxalates, and chronic or large-amount use raises the risk of low potassium and other problems. Talk to your pharmacist about how long it's appropriate for you.
Can I take yellow dock if I'm pregnant?
No. The safety data advises against it during pregnancy because there isn't enough safety data and yellow dock has laxative effects. Talk to your doctor or pharmacist about safe alternatives.
Can I take yellow dock while breastfeeding?
No. The safety data advises against it while nursing because laxative compounds may pass into breast milk. It's best to avoid it during this time.
What happens if I use too much yellow dock?
Raw or uncooked leaves are unsafe and can cause low blood calcium, kidney stones, and vomiting. Very large amounts (500 grams or more) have been linked to serious effects like breathing problems. Stick to proper preparation and use only as directed.
Can this product cause skin problems?
Yes — yellow dock can cause skin irritation (dermatitis) when consumed in large amounts, and touching the plant itself may cause a rash in sensitive people. Use cautiously and watch for any unusual skin changes.
