Synopsis
Source of validity: Traditional
Rating (out of 5): 3
Chinese Licorice (Glycyrrhiza uralensis) has been used in Traditional Chinese Medicine (TCM) for centuries to support the health of mucus membranes, particularly in the respiratory and digestive systems. In TCM, licorice is considered a harmonizing herb, often included in formulations to "moisten" the lungs, soothe coughs, and alleviate sore throat, which are symptoms often associated with irritation or inflammation of mucosal tissues. Historical texts such as the "Shennong Bencao Jing" (Divine Farmer’s Materia Medica) mention its use for symptoms related to dryness and inflammation of the throat and lungs.
Modern phytotherapy recognizes that licorice contains glycyrrhizin, a saponin glycoside, which exhibits anti-inflammatory and soothing (demulcent) properties. While some laboratory and animal studies suggest licorice extracts can modulate mucosal inflammation and may enhance mucus production, clinical evidence in humans specifically for mucus membrane support is limited. Most clinical research focuses on licorice’s role in treating peptic ulcers (lining of the stomach) and sore throats, which are related to mucus membrane health. However, the majority of supportive evidence comes from traditional use and historical documentation rather than robust modern clinical trials.
In summary, Chinese Licorice is justified for supporting mucus membranes primarily based on traditional use, with some suggestive but not conclusive scientific rationale.
