Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Licorice root (Glycyrrhiza glabra) has a long history of use in traditional medicine systems, including Traditional Chinese Medicine (TCM) and Ayurveda, for treating symptoms associated with colds, such as cough and congestion. In these traditions, licorice root is valued for its demulcent (soothing) properties and is often included in herbal formulations aimed at relieving irritation of the throat and supporting respiratory health. Its use as a decongestant is primarily rooted in these traditional practices rather than in robust modern scientific evidence. From a pharmacological perspective, licorice root contains glycyrrhizin, which has demonstrated anti-inflammatory and mild antiviral properties in laboratory settings. These properties may theoretically contribute to easing some symptoms of colds. However, clinical studies directly assessing licorice root’s efficacy as a decongestant or cold remedy in humans are limited and of mixed quality. Most available research focuses on its role in cough syrups or as a flavoring agent, rather than as a primary treatment for congestion. Thus, while there are plausible mechanisms and a rich history of traditional use, the scientific evidence specifically supporting licorice root as a decongestant for colds is weak, and safety concerns—especially with prolonged use—should also be considered. Overall, licorice root’s use for this purpose is best characterized as traditional, with a low to moderate level of supporting evidence.
