Horehound (Marrubium vulgare) as a tool for helping with Bronchitis
Expectorant for productive cough and catarrh of the upper respiratory tract / bronchitis
The aqueous extract of horehound (Marrubium vulgare), rich in polyphenols, was tested against bleomycin-induced pulmonary fibrosis in rats. It significantly reduced the inflammatory index and fibrosis score, decreased infiltration of inflammatory cells, and reversed oxidative-stress markers, demonstrating anti-inflammatory and antioxidant protection of lung tissue.
White horehound (Marrubium vulgare) has been traditionally used in Europe and the Mediterranean for respiratory diseases (acute/chronic bronchitis, colds, asthma), lack of appetite, dyspepsia, type II diabetes and as an antihypertensive. This review critically analyses the quality of the scientific evidence behind these ethnopharmacological uses of horehound.
