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 supporting respiratory health and alleviating bronchial congestion. In TCM, licorice root is often included in herbal formulas intended to "moisten the lungs," soothe sore throats, and ease coughing. Historical texts reference its expectorant and demulcent (soothing) properties, which are believed to help thin and expel mucus from the airways, thus easing congestion.

Modern scientific research on licorice root for bronchial congestion is limited. Some laboratory studies suggest that compounds in licorice, such as glycyrrhizin and liquiritin, may have anti-inflammatory, antimicrobial, and soothing effects on mucous membranes. A few small clinical studies and animal models have shown that licorice extracts can reduce airway inflammation and mucus production, but these findings are preliminary and not robust enough to establish efficacy. Most authoritative reviews conclude that while licorice root is traditionally used for respiratory ailments, rigorous clinical trials in humans are lacking.

In summary, licorice root’s use for bronchial congestion is primarily supported by traditional use, with some suggestive but insufficient scientific evidence. It is generally considered safe for short-term use, but long-term or excessive intake can cause serious side effects, including hypertension and electrolyte imbalances. Always consult a healthcare provider before using licorice root for respiratory issues.
