Black Walnut Ingredients & Drug Interactions
What is this page for?
First and foremost: checking Black Walnut against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Black Walnut by Red Moon Herbs
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.
What’s inside
Low disclosure
This product contains one active ingredient: Black Walnut Green Hull Extract, Fresh. Black walnut hull is the outer covering of the black walnut fruit and is traditionally used to support health, though clinical evidence for its specific benefits is limited.
The liquid form also contains water and alcohol as inactive ingredients.
Does it work?
Couldn't assess
The evidence we hold for black walnut does not establish that it is effective for coronary heart disease or wound healing — the ratings are insufficient reliable evidence to rate. That means the research to date isn't strong enough to say whether it works for these uses.
We don't hold effectiveness data for other claimed uses either.
How safe is it?
Well-documented data
Black walnut hull contains high amounts of tannins, compounds that can irritate your stomach and cause gastrointestinal upset when taken by mouth. The product may be acceptable for short-term use in most adults, but human safety data are limited and long-term use hasn't been well studied.
Tree nuts, including black walnuts, can trigger allergic reactions in people with tree nut allergies — tree nuts are a major food allergen in the United States.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we checked. That said, always run your exact medications through the checker on this page before you start any new supplement, or ask your pharmacist.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you're considering black walnut for a specific health goal, know that the evidence supporting it isn't yet established in our data. It's generally well tolerated for short-term use but can cause stomach upset due to tannin content.
Anyone with a tree nut allergy should avoid it. Talk to your pharmacist before starting, especially if you're pregnant, breastfeeding, or plan to use it long-term.
