THE ROLE OF WHITE HOREHOUND (Marrubium vulgare L.) IN MODERN MEDICINE AND TRADITIONAL FOLK HEALING

Abstract

White horehound (Marrubium vulgare L., Lamiaceae), as a medicinal plant, has long been widely used in folk medicine mainly for cough, to promote expectoration, for respiratory discomfort associated with colds, as well as for mild dyspepsia (abdominal bloating, meteorism/flatulence) and temporary loss of appetite. The Committee on Herbal Medicinal Products (HMPC) under the European Medicines Agency (EMA) notes that preparations made from the aerial parts of white horehound (Marrubii herba) may be used traditionally in adults and adolescents over 12 years of age: as an expectorant for cough associated with the common cold, for symptomatic relief of mild dyspeptic complaints, and for temporary loss of appetite. This article—based on scientific sources—describes the phytochemical composition of white horehound (especially marrubiin), possible mechanisms of action, the level of clinical evidence, preparation forms used in folk medicine, dosing approaches, and key safety considerations and restrictions.
