Black Walnut Ingredients & Drug Interactions
What is this page for?

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 Nature's Sunshine
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
Full disclosure
This product contains one active ingredient: Black Walnut hulls extract. The hull is the outer layer of the walnut fruit, and this extract form concentrates what's in that part of the plant.
Does it work?
Couldn't assess
The evidence for Black Walnut hulls extract isn't established yet. Our data shows insufficient reliable evidence to rate it for coronary heart disease or wound healing.
That doesn't mean it doesn't work — it means we don't have enough rigorous studies to say one way or the other.
How safe is it?
Well-documented data
Black Walnut hulls extract is generally well tolerated when taken by mouth. The main concern is that the hull contains high amounts of tannins, which can cause stomach upset or gastrointestinal irritation in some people.
Tree nuts, including walnuts, are a major food allergen in the United States, so if you have a tree nut allergy, you should avoid this. The safety data advises against use during pregnancy and breastfeeding — there isn't enough information to know it's safe in those situations.
Short-term use in most healthy adults appears acceptable, but long-term safety hasn't been well studied.
Meds to double-check
No known interactions
No interactions are documented in our data for Black Walnut hulls extract.
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 hulls extract may appeal to someone looking for a traditional herbal supplement, but the evidence for what it actually does isn't solid yet. If you have a tree nut allergy, are pregnant, breastfeeding, or have a sensitive stomach, talk to your pharmacist before starting it.
No interactions with medications are documented, but that's always worth a quick double-check with your exact drug list.
