HelloPharmacist Scorecard of Black Haw by Hawaii 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: a wildcrafted Black Haw extract. Black Haw is a traditional herbal remedy that's been used historically for various purposes.
The extract is suspended in vegetable palm glycerin, pharmaceutical-grade alcohol, and artesian Hawaiian purified water.
Does it work?
Not established
The evidence we have doesn't establish Black Haw as effective for asthma, diarrhea, miscarriage prevention, or dysmenorrhea (painful periods). All of these uses are listed as having insufficient reliable evidence to rate.
That means we simply don't have solid human studies to back them up yet.
How safe is it?
Some data gaps
Black Haw is generally used in traditional medicine, but human safety data are limited. The ingredient carries two avoid warnings: its effects on the uterus are uncertain, so you shouldn't use it unless a doctor advises otherwise, and there isn't enough safety information for nursing mothers.
No adverse effects were reported in our data.
Meds to double-check
No known interactions
No interactions are documented for Black Haw in our data. That doesn't mean none exist—it means we found no documented interactions to report.

The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and some safety-information gaps remain.
Black Haw is a traditional herbal remedy with limited human safety evidence and no documented effectiveness for the conditions listed. If you're considering it, talk to your doctor or pharmacist first—especially if you're pregnant, nursing, or have any concerns about uterine effects.
