Butcher's broom is a traditional European botanical.
The wording
The page describes it as used for circulatory support, included to encourage healthy blood flow to the lower limbs. That is traditional-use language.
The caveats
The page links no research on butcher's broom, and the amount is not printed. If you take blood pressure medicine or blood thinners, or have circulation concerns, ask a doctor or pharmacist before using it.
