Licorice

Also known as: DGL, deglycyrrhizinated licorice, Glycyrrhiza glabra

Licorice is the root of Glycyrrhiza glabra, which contains glycyrrhizin. The DGL form has the glycyrrhizin removed and is mainly used to soothe the stomach and oesophageal lining.

  • Soothing the throat and cough – traditional use
