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: Black Walnut Leaf Glycerite Liquid Extract, a concentrated plant extract made from black walnut leaves. The base is glycerin, a natural sweetener and preservative, plus chocolate flavor for taste.

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 on black walnut leaf for coronary heart disease and wound healing is insufficient to rate — meaning we don't have enough reliable human studies to say whether it works for those purposes. If you're considering it for a specific health goal, talk it over with your doctor or pharmacist about what the current science actually supports.

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 leaf is generally well tolerated in the short term for most adults, though long-term safety hasn't been well studied in humans. The leaf contains high quantities of tannins, which can cause stomach upset, nausea, or other gastrointestinal discomfort when taken by mouth.

Tree nuts, including black walnuts, are a major food allergen — if you have a tree nut allergy, avoid this product. There's also a note that daily use of juglone-containing walnut bark is linked to increased risk of tongue cancer and lip leukoplakia, so if you're thinking of long-term use, discuss it with your doctor first.

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.

If you're curious about black walnut leaf extract and have no tree nut allergy, short-term use appears generally well tolerated — but the evidence for what it actually does isn't established. Before you start, especially if you're pregnant, breastfeeding, or taking any medications, check in with your doctor or pharmacist to make sure it fits your situation.

Black Walnut Leaf Chocolate Flavor by TerraVita: Common Questions

Does Black Walnut Leaf Chocolate Flavor by TerraVita interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Black Walnut Leaf Chocolate Flavor. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Black Walnut Leaf Chocolate Flavor 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 while pregnant or breastfeeding?
The safety data we hold advises against use during breastfeeding. For pregnancy, there isn't enough information to know either way — talk with your doctor or pharmacist about whether it's right for you.
What are the side effects?
The leaf contains tannins, which commonly cause stomach upset or other gastrointestinal discomfort. If you have a tree nut allergy, avoid it — black walnuts can trigger allergic reactions. Long-term use isn't well studied in humans, so if you're planning to take it regularly, check with your doctor first.
Does black walnut leaf actually work for heart disease or wound healing?
We don't have enough reliable evidence to say. The studies we hold rate both uses as having insufficient evidence. Your doctor or pharmacist can discuss what's known and whether it's a reasonable option for your situation.
What is black walnut leaf extract?
It's a concentrated liquid extract made from the leaves of the black walnut plant. This product delivers it in a glycerin base with chocolate flavor.
Is this safe for long-term use?
Short-term use is generally well tolerated, but we don't have good human safety data for long-term use. If you're thinking of taking it regularly, talk with your doctor or pharmacist first.
