From the Manufacturer:
DGL has become known as "The Lining Tamer" for a very good reason! Studies have shown that DGL stimulates and accelerates the natural protective factors in the digestive tract, which helps relieve stomach discomofort immediately.
DGL from Enzymatic Therapy is a unique extract of deglycyrrhizinated licorice widely used in Europe. It's chewable because saliva enhances the effect of DGL's natural compounds. In DGL, the glycyrrhizin compound-associated with high blood pressure-has been removed.
