Pillar 1: Mucociliary Clearance & Soothing (Mullein 10:1)
Mullein leaf (*Verbascum thapsus*) is rich in hydrophilic mucilage polysaccharides, iridoid glycosides (aucubin), and triterpene saponins [1]. When delivered via oral mist, mucilage forms a soothing hydrocolloid film across the oropharynx while saponins support healthy fluid balance inside the bronchial mucus blanket [5], [7]. Because Breathizen uses a 10:1 concentrated extract, each 0.60 mL serving reflects the botanical equivalent of ten parts dried leaf material.
