• Provides 400 mg DGL per tablet, the clinically effective dosage
• Deglycyrrhizination prevents adverse effects associated with licorice consumption
• Pleasant tasting tablets for better compliance

Deglycyrrhizinated licorice, or DGL, has been used clinically for decades, primarily for the treatment of peptic ulcers.1 Licorice has been shown to inhibit several inflammatory enzymes, including both cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), decreasing the production of several potent inflammatory compounds, including prostaglandin E2, thromboxane B2, and leukotriene B4. Importantly, this inhibition is not due to glycyrrhizic acid, the component of licorice which has been removed in DGL, and which is associated with mineralocorticoid excess and hypertension.2 Another component of licorice, glabridin, has been shown to prevent lipopolysaccharide (LPS) induced production of inflammatory compounds, including nitric oxide and interleukin-1 beta, whereas glycyrrhizic acid has no effect.
Clinically, DGL has been shown to have comparable efficacy to cimetidine for both the healing and prevention of ulcer recurrences.3 Additionally, extracts of licorice have been shown to inhibit the adhesion of H. pylori to gastric mucosa, as well as the growth of antibiotic resistant strains, suggesting multiple mechanisms of action for its anti-ulcer benefit.4,5 The use of chewable tablets appears necessary for DGL's efficacy, as it allows for distribution and absorption by the gastric mucosa.3

Chew 1 tablet per day 20 minutes prior to each meal, or as directed by a health care practitioner. Consult a health care practitioner for use beyond 16 weeks.
Potential side effects/Safety
Nearly all contraindications to DGL are due to pseudohyperaldosteronism or mineralocorticoid excess, effects which appear to be primarily due to glycyrrhizic acid. Although there are no apparent contraindications for DGL, patients with hypertension, congestive heart failure and hypokalemia should be monitored carefully. The safety of DGL in pregnancy and breastfeeding is unknown and should be used with caution. Consult a health care practitioner if symptoms persist or worsen. Keep out of reach of children.
No known drug interactions. Licorice influences the activity of several cytochrome enzymes, and reduces warfarin activity in animal models, likely due to glycyrrhizic acid activity. Thus DGL use should be carefully monitored in these patients.
