As an expectorant, Lung, Bronchial & Sinus Health helps soothe respiratory airways by thinning mucus and loosening phlegm and bronchial secretions.

This wide-ranging formula also features demulcent marshmallow extract to help soothe irritated mucous membranes and herbal expectorants (wild cherry bark, mullein, and horehound) that help improve bronchial secretions.
