HelloPharmacist Scorecard of Yellow Dock by Herbalist & Alchemist

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.

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: a fresh Yellow Dock root extract. Yellow Dock is a plant whose root has been used traditionally as a mild laxative and nutritional support.

The liquid is made with distilled water, ethyl alcohol, and vegetable glycerin 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: promotes healthy skin and liver function.
  • We looked for evidence on: Skin health, Liver health, Detoxification, Digestive support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't hold effectiveness ratings for Yellow Dock in our data, so we can't tell you what the scientific evidence says about how well it works for any particular 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 it's properly prepared and used in food amounts. The main caution is that it acts as a laxative and contains oxalates, so it's best used short-term and with care — especially if you're prone to kidney stones or have calcium absorption issues.

The safety data advises against taking Yellow Dock during pregnancy or while nursing because there isn't enough safety information and the laxative compounds may pass into breast milk. Raw Yellow Dock leaves or roots can be unsafe and may cause serious problems like low blood calcium (hypocalcemia), kidney stones, and vomiting; stick with properly prepared versions.

In large amounts, it can also cause skin irritation (dermatitis) when taken by mouth or from direct contact with the plant.

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.

Before taking Yellow Dock, double-check if you use diuretics (water pills), digoxin (Lanoxin) for your heart, or warfarin (Coumadin) as a blood thinner — all three carry serious interaction potential. If you're unsure whether your blood pressure or heart medication is a diuretic, ask your pharmacist.

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 is traditionally used as a gentle digestive support, but it's not one to take lightly if you're on heart or blood pressure medications — especially digoxin, diuretics, or warfarin. Check your exact medications with the tool on this page before starting, and talk with your pharmacist if you take anything for your heart or blood clotting.

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 Herbalist & Alchemist: Common Questions

Does Yellow Dock by Herbalist & Alchemist 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 pregnant?
The safety data advises against it. There isn't enough information to know whether it's safe during pregnancy, and the laxative effect is a concern. Talk with your doctor or pharmacist before taking this if you're pregnant or planning to be.
Is it safe to take Yellow Dock while breastfeeding?
No — the safety data recommends avoiding it while nursing because the laxative compounds may pass into breast milk. It's best to skip this one until you're done nursing.
What are the side effects of Yellow Dock?
When properly prepared and used in normal amounts, it's generally well tolerated. The main side effect is its laxative action. Rare serious effects from raw or old leaves include low blood calcium, kidney stones, and vomiting. Large amounts can cause skin irritation.
Why can't I just use raw Yellow Dock from my garden?
Raw Yellow Dock leaves and roots can be unsafe and may cause serious problems like low blood calcium, kidney stones, and vomiting. This product is a properly prepared extract — that's different and safer than eating raw plant material.
How long should I take Yellow Dock for?
The safety data recommends using it short-term and with care, rather than long-term. If you're thinking of using it regularly, talk with your pharmacist first.
Does Yellow Dock contain oxalates?
Yes, it does. That's one reason the data recommends caution — oxalates can contribute to kidney stones and affect calcium absorption, so it's not ideal if you have a history of either.
