Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Licorice (Glycyrrhiza glabra) has a long history of use in traditional medicine systems, particularly in Traditional Chinese Medicine (TCM) and Ayurveda, where it is valued for its soothing effects on the throat and its ability to "moisten" the lungs. Herbalists and singers have historically used licorice root teas, extracts, and lozenges to alleviate throat irritation, hoarseness, and cough, which are symptoms often associated with vocal strain. The demulcent properties of licorice—meaning its ability to form a soothing film over mucous membranes—are believed to provide relief and support for the vocal cords.

While there is a body of clinical and preclinical research on licorice's anti-inflammatory and demulcent effects, most studies focus on its use for gastric or respiratory conditions, not specifically for direct support of the vocal cords. However, its general soothing effects on mucous membranes lend some indirect support for its traditional use in this context. It is important to note that licorice contains glycyrrhizin, which can cause side effects such as hypertension and potassium loss if consumed in large amounts or over long periods.

In summary, licorice's application for vocal cord support is primarily grounded in tradition and historical usage, with some plausible mechanisms based on its known effects on mucous membranes, but there is limited direct scientific evidence specifically validating its use for vocal cords.
