Short answer: Butcher's Broom contains ruscogenins with a natural venotonic effect, acting as a gentle diuretic that helps flush retained water.
Why "gentle" is a deliberately modest, honest qualifier
This word choice distinguishes Butcher's Broom's natural diuretic action from a harsher, pharmaceutical-strength diuretic effect.
Why "venotonic" is a specific, named property
This term refers specifically to supporting vein tone and function — a checkable, specific mechanism distinct from a general water-retention claim.
💡 Worth knowing: increased urination as the diuretic botanicals work is listed directly as an expected, disclosed effect — not a concerning side effect.
