Synopsis

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

Licorice root (Glycyrrhiza glabra) has a long-standing history in traditional medicine systems, such as Traditional Chinese Medicine (TCM) and Ayurveda, where it has been employed to address a variety of digestive complaints, including nausea and vomiting. In these traditions, licorice root is believed to soothe the stomach lining and reduce inflammation, which may help relieve gastrointestinal discomfort. Its demulcent properties—meaning it can form a soothing film over mucous membranes—are thought to protect the stomach and esophagus from irritation caused by gastric acids or toxins.

However, direct scientific evidence supporting licorice root's efficacy specifically for nausea and vomiting is limited. Most clinical research on licorice focuses on its effects on gastric ulcers, inflammation, and respiratory issues. Some studies suggest that deglycyrrhizinated licorice (DGL) may aid in healing gastric mucosa, potentially reducing symptoms that can include nausea. However, these studies rarely isolate nausea and vomiting as primary endpoints, and robust randomized controlled trials for this use are lacking.

In summary, while licorice root continues to be used in traditional medicine for gastrointestinal complaints, including nausea and vomiting, the scientific validation for these particular uses is weak. Its use remains primarily tradition-based, and more high-quality clinical research is needed to confirm its efficacy for these symptoms.
