HelloPharmacist Scorecard of Yellow Dock Root Whole Herb And Extract (Rumex crispus) by Wachters'

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

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 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (790 mg) without saying how much of each component you get.

This product contains 3 active ingredients. Yellow dock root (whole herb and extract) is the main component, combined with chlorophyll and a proprietary blend that includes Wachters' Exclusive Blend of Sea Vegetation.

No inactive fillers or binders are listed.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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 have don't include effectiveness ratings for yellow dock root itself. Chlorophyll is listed with insufficient evidence for several uses—genital herpes, wound healing, shingles, skin cancer, and pancreatitis—meaning the research data on file isn't strong enough to rate whether it works for any of those.

We'd need to know what you're hoping this product does for you; the data we hold doesn't establish that it works for any particular condition.

The evidence, ingredient by ingredient Chlorophyll 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Chlorophyll is generally well tolerated in the short term, though high-quality safety data are limited. The main adverse effect is photosensitization—increased sun sensitivity—and in rare cases, a condition called pseudoporphyria (blistering on the hands) has been reported after oral use.

Yellow dock may act as a laxative and contains oxalates; the facts recommend short-term use and caution. Raw leaves or rhizomes can cause serious problems including low blood calcium (hypocalcemia), kidney stones, and vomiting.

Avoid older or uncooked leaves. In large amounts, yellow dock can cause skin irritation when consumed.

We have no pregnancy or breastfeeding safety data on file for yellow dock itself; chlorophyll is best avoided in pregnancy and while nursing because safety data are insufficient.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Yellow Dock, Chlorophyll.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 353 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 your medications against these types before starting: digoxin or other heart drugs affected by low potassium; diuretics (water pills); warfarin or other blood thinners; any photosensitizing drugs that increase sun sensitivity; and methotrexate. These carry Major or Moderate interaction risks with ingredients in this product.

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.

If you take a heart medication like digoxin, a diuretic, warfarin, a photosensitizing drug, or methotrexate, you need to check with your pharmacist before using this product. The laxative properties and oxalate content also mean it's not meant for long-term daily use.

Talk to your pharmacist about whether this fits your medications and health situation.

Chlorophyll2 drug types · 337 drugs

Methotrexate (Trexall, Others)

Theoretically, chlorophyll may reduce the clearance of methotrexate.
In one case report, a 54-year-old male developed delayed clearance of intravenous high-dose methotrexate with concomitant use of chlorophyll. When chlorophyll was stopped 2 days prior to methotrexate treatment, methotrexate clearance was unaffected.

Likelihood Possible Evidence B
Photosensitizing Drugs

Theoretically, concomitant use of chlorophyll with photosensitizing drugs may have additive effects.
Chlorophyll has been reported to cause photosensitization. In two case reports, pseudoporphyria developed after oral intake of chlorophyll. Theoretically, concomitant use with other photosensitizing drugs may exacerbate this effect.

Likelihood Probable Evidence B
Chlorophyll full monograph & interactions

Yellow Dock Root Whole Herb and Extract3 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 Root Whole Herb And Extract (Rumex crispus) by Wachters': Common Questions

Does Yellow Dock Root Whole Herb And Extract (Rumex crispus) by Wachters' interact with any medications?
Yes. Based on its ingredients, Yellow Dock Root Whole Herb And Extract (Rumex crispus) has a known interaction with 353 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 Root Whole Herb And Extract (Rumex crispus) contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this if I'm on a diuretic or water pill?
Not without talking to your pharmacist first. Yellow dock can lower potassium levels, and diuretics do the same thing—together, they could drop your potassium dangerously low. Your pharmacist needs to know you're considering this product.
What does yellow dock actually do?
The product facts we hold don't include effectiveness ratings for yellow dock, so we can't tell you from our data what condition it's meant to treat or whether research supports that use. Your pharmacist can help clarify.
Is it safe to use long-term?
No. The facts recommend short-term use only because yellow dock acts as a laxative and contains oxalates. It's not designed for ongoing daily use, and raw or older leaves should be avoided entirely.
Can I take this while pregnant or breastfeeding?
The safety data advises against it in both pregnancy and breastfeeding. For yellow dock, there isn't enough safety information. For chlorophyll, there also isn't enough data to know either way. Talk with your doctor or pharmacist for personalized advice.
What side effects might I notice?
Chlorophyll can cause photosensitization—increased sensitivity to sun—which is the most common effect reported. In rare cases, it's been linked to blistering on the hands. Yellow dock can cause skin irritation in large amounts and acts as a laxative.
