What It Actually Is
Butcher's Broom is a shrub whose root has a long history of traditional use in Europe, primarily associated with vein and circulatory health.
What Research Generally Shows
Most research on Butcher's Broom focuses on its compounds called ruscogenins, studied mainly for supporting healthy blood vessel tone and circulation.
The Honest Gap
Its specific amount in Lungora isn't broken out from the 575mg blend, so we can't confirm it matches doses used in circulation-focused research.
