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: Black Haw Bark Extract, Dry. Black Haw is a plant traditionally used in herbal medicine, though human safety and effectiveness data remain limited.
The liquid also contains alcohol, water, and glycerin as inactive ingredients.
Does it work?
Not established
The evidence we hold doesn't establish how well Black Haw works for asthma, diarrhea, miscarriage prevention, or period pain (dysmenorrhea). For all of these uses, the data are insufficient to rate it.
If you're considering this for one of those purposes, talk with your pharmacist or doctor about what the evidence actually supports.
How safe is it?
Some data gaps
Black Haw is generally used in traditional medicine, but human safety data are limited, so caution is warranted. The effects on the uterus are uncertain — the safety data advise against use in pregnancy unless a doctor specifically recommends it, as it's rated possibly unsafe.
There isn't enough safety information for nursing mothers, so breastfeeding while taking this product should be discussed with your doctor or pharmacist first.
Meds to double-check
No known interactions
No interactions are documented in our data for Black Haw Bark Extract. Check your exact medications with the search tool on this page to be sure, and talk with your pharmacist if you take anything for hormone-related conditions or if you're pregnant or nursing.
