Synopsis
Source of validity: Traditional
Rating (out of 5): 3
Licorice root (Glycyrrhiza glabra) has a long history of use in traditional medicine systems, including Traditional Chinese Medicine (TCM), Ayurveda, and various folk remedies, to help relieve respiratory congestion and soothe the lungs. In TCM, licorice root is often included in herbal formulas to "clear heat" and "resolve phlegm," addressing symptoms like cough and mucus buildup. Its demulcent (soothing) and expectorant properties have been cited for helping to thin and expel mucus, easing breathing and reducing irritation in the respiratory tract.
While there is some preclinical scientific evidence suggesting that licorice root contains compounds (such as glycyrrhizin and liquiritin) with anti-inflammatory, antimicrobial, and mucolytic (mucus-thinning) properties, high-quality clinical trials in humans are limited. Some small studies and laboratory research indicate that licorice extracts can inhibit certain respiratory pathogens and reduce airway inflammation, but these effects have not been robustly confirmed in large-scale human trials for congestion specifically.
Overall, the use of licorice root for lung congestion is primarily rooted in tradition, with moderate supporting evidence from preclinical studies and limited human data. It remains a popular herbal remedy, but individuals should use caution due to potential side effects like hypertension with long-term or high-dose use.
