Herb Pharm Black Haw
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that black haw, as formulated by Herb Pharm, has limited data to support its use for general health. While the ingredient calcium is present in the product, the specific effects of black haw itself are not well-documented in the data provided. You should not rely on this supplement for any specific health benefit without consulting a healthcare provider, as the primary data available pertains to calcium, not the whole herb.
How it works
Black haw is traditionally used, but the provided data only describes the mechanism of one of its ingredients, calcium. Calcium supports bone mineralization and neuromuscular relaxation, meaning it helps relax muscles and support nerve signaling [NIH ODS]. This does not confirm that black haw itself has these effects, as the herb's full mechanism is not described in the data.
Safety profile
Data not available for black haw specifically. The FDA received a total of 592,059 adverse event reports across all supplements, but no reports are listed for this product. For the ingredient calcium, high intakes can cause constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Based on the available data, we cannot recommend black haw for any specific purpose. If you are considering this supplement, you should discuss it with your doctor, especially if you take any medications that interact with calcium. The evidence is insufficient to support its use, and you should prioritize supplements with stronger clinical backing.
