HelloPharmacist Scorecard of Cramp Bark (Viburnum) Powder by TerraVita Premium Collection
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: cramp bark powder (a traditional name for Viburnum). It has no inactive fillers or other ingredients listed.
Does it work?
Insufficient evidence
The evidence for cramp bark isn't established in the data we hold. It's been used in traditional medicine for muscle cramps, dysmenorrhea (painful menstrual cramps), pregnancy-related leg cramps, diabetes, and kidney stones, but we have insufficient reliable evidence to rate how well it actually works for any of these uses.
How safe is it?
Some data gaps
Cramp bark is generally well tolerated in traditional use, but human safety data are limited — we don't have a full picture of how safe it is overall. The safety data advise against it during pregnancy, and there isn't enough information to know whether it's safe while breastfeeding.
If you're pregnant or nursing, talk with your doctor or pharmacist before using it.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. Still, run your exact medications through the search tool on this page, and talk with your pharmacist or doctor before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
Cramp bark is a traditional herbal powder with no documented medication interactions, but human safety research is sparse. If you're considering it for muscle cramps or menstrual symptoms and you take any medications or are pregnant or breastfeeding, check with your own doctor or pharmacist first — the limited safety data mean you'll want personalized advice.
