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.

Green Black Walnut Hull by Mountain Meadow Herbs is a single-ingredient liquid: an extract of the hull (the outer green covering) of black walnut fruit. There are no other active ingredients and no inactive fillers 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

This is a single-ingredient Black Walnut product and its label doesn't state a use — see Black Walnut'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 evidence we hold doesn't establish how well black walnut hull works. For coronary heart disease (CHD) and wound healing — the two uses in our data — the research is rated insufficient to say whether it's effective or not.

If you're considering it for either of those reasons, talk with your doctor about what the current evidence actually supports and whether it makes sense for your situation.

The evidence, ingredient by ingredient Black Walnut

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.

Black walnut hull is generally well tolerated in the short term for most adults, but human safety data are limited and long-term use hasn't been well studied. The hull contains high amounts of tannins, which can cause stomach upset and digestive irritation when you take it by mouth.

A small number of people may have a tree nut allergy; black walnuts are a major food allergen in the United States, so if you have a tree nut allergy, avoid this product. During pregnancy, there isn't enough safety information — the data advises against use.

While breastfeeding, safety data are also insufficient; talk with your doctor or pharmacist about whether it's appropriate for you. Additionally, daily use of the bark of a related walnut species has been linked to increased risk of tongue cancer and lip leukoplakia, so you should avoid long-term daily use of black walnut hull preparations without medical supervision.

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the green black walnut hull extract in this product. However, absence of documented interactions is not a guarantee none exist, so it's still smart to confirm with your own pharmacist before combining it with any prescription medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Green Black Walnut Hull may be okay for short-term use in adults if your doctor or pharmacist clears it for your situation, but the research on how well it works is incomplete. Avoid it if you're pregnant, breastfeeding, or have a tree nut allergy.

Talk with your own doctor or pharmacist before starting — especially if you have digestive concerns or are thinking about using it long-term.

Green Black Walnut Hull by Mountain Meadow Herbs: Common Questions

Does Green Black Walnut Hull by Mountain Meadow Herbs interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Green Black Walnut Hull. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Green Black Walnut Hull 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.
Will this upset my stomach?
Possibly. Black walnut hull is high in tannins, which commonly cause gastrointestinal upset when taken by mouth. If you have a sensitive stomach, start cautiously and monitor how you feel. If it bothers you, stop and talk with your pharmacist.
Can I take this if I'm pregnant or breastfeeding?
No. There isn't enough safety information during pregnancy, so it's best avoided. The same goes for breastfeeding — the data don't support use during lactation either. Talk with your doctor or pharmacist if you're considering it.
What is black walnut hull supposed to do?
The data we hold look at it for heart disease and wound healing, but the research isn't strong enough yet to say whether it actually works for either one. If you're interested in it for a specific health reason, ask your doctor what the current evidence supports.
Is this safe to use long-term?
Not much is known. It may be fine short-term for most adults, but long-term safety hasn't been well studied in people. Don't use it daily for weeks or months without checking in with your doctor or pharmacist first.
Can I take this if I have a nut allergy?
No. Black walnuts are a tree nut and a major food allergen. If you have any tree nut allergy, avoid this product entirely.
