Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Chinese Licorice (Glycyrrhiza uralensis) has a long history of use in Traditional Chinese Medicine (TCM) for treating colds and respiratory infections. Traditionally, it is believed to harmonize herbal formulas and soothe the throat. Recent scientific studies have investigated its antiviral properties, particularly due to its active compound glycyrrhizin. In vitro research has shown that glycyrrhizin can inhibit the replication of several viruses, including those responsible for respiratory infections like influenza and some coronaviruses (Cinatl et al., 2003). Additionally, licorice extracts have demonstrated anti-inflammatory effects, which may help reduce symptoms associated with colds. However, the evidence supporting the use of Chinese Licorice specifically for treating or preventing common colds in humans is limited. Most clinical studies have been small or focused on related conditions such as chronic hepatitis or broader immune support. There is a lack of large-scale, high-quality randomized controlled trials confirming its efficacy against cold viruses in humans. Safety concerns regarding long-term or high-dose use (such as hypertension and hypokalemia due to glycyrrhizin) are also noted. In summary, while laboratory studies lend some scientific support to the antiviral potential of Chinese Licorice, particularly through glycyrrhizin, robust clinical evidence for its effectiveness in treating or preventing colds is weak. Its use for colds is thus weakly supported by modern science, though it remains a staple in traditional practices.
