HelloPharmacist Scorecard of Cramp Bark by Herbal Terra
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
Cramp Bark by Herbal Terra is a one-ingredient liquid extract made from the dried bark of Viburnum opulus, also called cramp bark — a plant used in traditional medicine. The extract is suspended in menstruum, which is the liquid solvent used to draw out the plant's active compounds.
Does it work?
Insufficient evidence
The evidence for Cramp Bark isn't established in the data we hold. It has been used traditionally for muscle cramps, period pain (dysmenorrhea), kidney stones, pregnancy-related leg cramps, and diabetes, but we don't have reliable scientific evidence to rate how well it works for any of these uses.
If you're thinking about it for a specific concern, talk it over with your doctor or pharmacist.
How safe is it?
Some data gaps
Cramp Bark is generally used in traditional medicine, but human safety data are limited — we know relatively little about how it affects the body in real-world use. The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know it's safe in those situations.
If you're pregnant, nursing, or planning to become pregnant, check with your doctor or pharmacist before taking this product.
Meds to double-check
No known interactions
No interactions are documented for Cramp Bark in our data. That's good news on the medication front — but it's still worth running your specific prescriptions through the search tool on this page and confirming with your pharmacist before you start.
The bottom line

Cramp Bark is a traditional herbal remedy with no documented medication interactions, but the scientific evidence for its effectiveness isn't established. It's not recommended during pregnancy or breastfeeding.
If you're considering it for muscle cramps, period pain, or another condition, talk it over with your own doctor or pharmacist to see if it fits your needs.
