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

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: freeze-dried black walnut at 400 mg per capsule. The capsule itself is made with hypromellose, a plant-based film material.

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 for black walnut is limited. For coronary heart disease and wound healing, there isn't enough reliable evidence to say whether it works.

You'll want to talk with your doctor or pharmacist about whether this is the right choice for what you're trying to address.

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 fruit itself is generally well tolerated when taken by mouth. However, the leaf, bark, and hull contain high amounts of tannins, which can cause gastrointestinal upset if you take them orally.

Because human safety data are limited and long-term use hasn't been well studied, short-term use is considered acceptable for most adults — but we don't have a lot of information about using it over months or years. The product should be avoided during pregnancy and breastfeeding, as there isn't enough safety information.

Tree nuts, including black walnuts, can trigger allergic reactions in sensitive people; they're classified as a major food allergen in the United States.

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.

Black Walnut 400 mg has no documented medication interactions. It's generally tolerated short-term by most adults, but evidence for its effectiveness is insufficient and long-term safety data are lacking.

Avoid it if you're pregnant or breastfeeding, and watch for tree nut allergy symptoms. Talk with your pharmacist before starting if you're looking to treat a specific health concern.

Black Walnut 400 mg by Eclectic Herb: Common Questions

Does Black Walnut 400 mg by Eclectic Herb interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Black Walnut 400 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Black Walnut 400 mg 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 this if I'm pregnant or breastfeeding?
The data advises against it. There isn't enough safety information for pregnancy or breastfeeding, so it's best avoided during both. Talk with your doctor or pharmacist for personalized guidance.
What's the difference between the nut and the leaf, bark, or hull?
The actual nut is well tolerated by mouth. The leaf, bark, and hull contain high amounts of tannins, which can cause stomach upset and other GI problems. This product is freeze-dried black walnut — the nut — so it shouldn't carry that tannin risk, but be aware it's a tree nut and could trigger an allergy.
Is this safe to take long-term?
We don't have enough data. Black walnut is considered acceptable short-term for most adults, but human safety studies are limited and long-term use hasn't been well studied. If you're planning to use it regularly for months or more, check with your pharmacist first.
Could I have an allergic reaction to this?
Yes, it's possible. Black walnuts are tree nuts and a major food allergen in the United States. If you're sensitive to tree nuts or have a known allergy, avoid this product.
Does this actually work for heart health or wound healing?
There isn't enough reliable evidence to say either way. For both coronary heart disease and wound healing, the evidence is insufficient to rate whether it helps.
