Licorice root (Glycyrrhiza glabra) has a long history of use in traditional medicine systems, including Traditional Chinese Medicine (TCM) and Ayurveda, for addressing respiratory issues such as congestion and cough. In TCM, licorice root is considered a harmonizing herb and is frequently included in formulas to soothe the throat, reduce phlegm, and ease breathing. It is believed to have expectorant and demulcent properties, which help to loosen mucus and relieve irritation in the respiratory tract.

From a scientific perspective, licorice root contains glycyrrhizin and other compounds that exhibit mild anti-inflammatory and antimicrobial effects, which could theoretically support respiratory health. There is some laboratory and animal research suggesting these constituents might reduce inflammation in the airways and inhibit certain pathogens. However, direct clinical evidence specifically supporting licorice root’s efficacy in treating sinus congestion in humans is limited. Most human studies on licorice focus on its effects in sore throat, cough, or gastric issues rather than nasal or sinus congestion.

Overall, while licorice root’s use for congestion is well-established in traditional medicine, robust clinical trials are lacking. People interested in using licorice root for congestion should be mindful of potential side effects (such as increased blood pressure) and should consult a healthcare provider, especially if using it for more than a few days or in large amounts.
