DGL is a specially processed form of licorice root from which the glycyrrhizin compound has been removed to below 0.6% — eliminating the blood pressure-raising potential of standard licorice root while retaining the gut-protective, mucus-stimulating, and soothing properties that make licorice one of the most important digestive herbs in both Eastern and Western herbal medicine. Research supports DGL for stimulating the proliferation of mucus-secreting goblet cells in the digestive tract, supporting the mucosal lining of the stomach and intestines, and reducing the discomfort associated with gastritis, ulcers, and acid-related digestive conditions. Because DGL works through mucosal stimulation rather than acid suppression, it supports the gut lining without disrupting the digestive process.
What It's Known For
Licorice root has been used in traditional medicine for over 4,000 years across China, Egypt, Greece, Rome, and Ayurvedic practice. One of the most frequently used herbs in Traditional Chinese Medicine — appearing in the Shennong Bencao Jing as a superior harmonizing herb. European herbalism used licorice extensively for respiratory and digestive conditions. DGL form developed in the 20th century to allow long-term therapeutic use without the blood pressure concerns of whole licorice root.
Benefits
• Research shows DGL stimulates proliferation of mucus-secreting goblet cells in the digestive tract
• Studies support healthy stomach lining and gastric mucosal protection
• Known to support digestive comfort and reduce symptoms associated with gastritis

• Studies demonstrate support for intestinal lining integrity
• Known soothing properties for esophageal and gastric tissue
