HelloPharmacist Scorecard of Black Walnut by Herb Pharm
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 green hull extract from Juglans nigra. The extract is suspended in a liquid base of certified organic cane alcohol, vegetable glycerin, vinegar, and distilled water.
Does it work?
Couldn't assess
The evidence for black walnut extract isn't well established for the conditions it's traditionally used for. Our data shows insufficient reliable evidence to rate it for coronary heart disease or wound healing.
If you're considering it for a specific health goal, talk with your pharmacist or doctor about what the research actually supports.
How safe is it?
Well-documented data
Black walnut extract 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 tannins it contains may cause stomach upset or other gastrointestinal discomfort.
Because black walnuts are a major tree nut allergen, there's a risk of allergic reaction in sensitive individuals. The safety data advises against use during pregnancy and while breastfeeding due to insufficient information.
Meds to double-check
No known interactions
No interactions are documented in our data for black walnut extract. That doesn't mean none exist, so run your exact medications through the checker on this page before you start.
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 extract is generally well tolerated in the short term if you don't have a tree nut allergy and aren't pregnant or breastfeeding. If you fall into either of those groups, or if you have questions about whether it's right for your situation, check with your pharmacist or doctor first.
