Synopsis

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

Licorice root (Glycyrrhiza glabra) has a long history of use in traditional medicine systems, particularly in Traditional Chinese Medicine (TCM) and Ayurveda, for treating various throat and respiratory conditions, including laryngitis. The root is valued for its soothing, demulcent (mucus-soothing), and anti-inflammatory properties. Historically, licorice root has been used as an ingredient in herbal teas, lozenges, and gargles to relieve sore throat, hoarseness, and inflammation associated with laryngitis.

From a scientific standpoint, licorice root contains glycyrrhizin, which has demonstrated anti-inflammatory and antimicrobial effects in laboratory and animal studies. Some small clinical studies and reviews suggest that licorice may help reduce throat pain and irritation. For example, licorice gargles have been found to reduce postoperative sore throat in several randomized controlled trials. However, there is limited direct clinical evidence specifically addressing the efficacy of licorice root for acute laryngitis. Most supporting evidence is extrapolated from studies on sore throat or general upper respiratory tract irritation.

In summary, the use of licorice root for laryngitis is primarily justified by tradition, with some plausible mechanisms and limited scientific support. More rigorous clinical trials are needed to confirm its effectiveness specifically for laryngitis. Individuals should also be cautious with licorice use, as long-term or excessive intake can cause significant side effects, including hypertension and electrolyte imbalances.
