Butcher's Broom Root Extract is a traditional botanical long associated with venous tone and healthy circulation, most commonly used for leg and vascular support.
Its connection to respiratory wellness is indirect — better circulation generally supports more efficient oxygen delivery throughout the body, lungs included.
Direct respiratory research on this specific ingredient is limited; its inclusion here leans more on its established circulatory reputation.
Where it sits in the formula: part of Lungora's Circulation & Cellular Energy category, alongside L-Carnitine, Coenzyme Q10.
