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 (Viburnum), in powder form. Cramp bark is a traditional herbal remedy, though human safety data remain limited.
Does it work?
Insufficient evidence
The evidence we hold on cramp bark doesn't establish that it works for any of the conditions it's traditionally used for — including muscle cramps, period pain (dysmenorrhea), kidney stones, pregnancy-related leg cramps, or diabetes. The ratings are insufficient reliable evidence for all of them, which means the science isn't there yet to say whether it helps.
How safe is it?
Some data gaps
Cramp bark is generally used in traditional medicine, but human safety data are limited — we don't have a lot of real-world information on how it affects people. The safety data advises against using it during pregnancy, and there isn't enough information to know whether it's safe while breastfeeding.
If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist about whether this product is right for you.
Meds to double-check
No known interactions
No interactions are documented in our data for cramp bark. That's not a guarantee that none exist, so confirm with your own doctor or pharmacist before combining it with any prescription or over-the-counter drugs.
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 remedy, but the evidence doesn't yet establish that it works for muscle cramps, period pain, or the other conditions it's used for. If you're considering it, check with your own doctor or pharmacist first — especially if you're pregnant, breastfeeding, or taking any medications.
