Deglycyrrhizinated Licorice (DGL)
The safe form of licorice for healing the stomach lining.
Also known as: DGL • Glycyrrhiza glabra
Overview
Deglycyrrhizinated licorice, or DGL, is a form of licorice root that has had glycyrrhizin removed. Glycyrrhizin is the compound responsible for the potential side effects of licorice, such as high blood pressure and low potassium levels. DGL retains the beneficial compounds that help heal the stomach lining, making it a safe and effective remedy for peptic ulcers, acid reflux, and gastritis. It works by increasing mucus production, which protects the stomach from acid.
