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. Yellow dock is a plant root traditionally used to support digestive and liver function, though it also has a laxative effect.

The extract is prepared as a glycerite (an alcohol-free extract using glycerin as the preservative) and flavored with vanilla. Glycerin and vanilla flavor are inactive ingredients added for taste and preservation.

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?

No effectiveness ratings are on file in our data for yellow dock root. While it's been used traditionally for various purposes, we don't hold clinical evidence that establishes whether it works for any particular condition.

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 properly prepared and used in food amounts for the short term. The main caution is its laxative effect and its oxalate content — using it long-term or in large amounts raises the risk of potassium loss and other complications.

Consuming raw leaves or rhizomes can be unsafe and may cause low blood calcium (hypocalcemia), kidney stones, or vomiting. Large doses have been linked to skin reactions, and there's one historical report of respiratory depression from an extremely high dose.

During pregnancy, safety data advises against use. While breastfeeding, the laxative compounds may pass into breast milk, so it's best avoided.
