Question 1

How does DGL licorice work to heal the stomach lining?

Accepted Answer

DGL works by stimulating mucus secretion and increasing the production of mucosal prostaglandins, which protect the stomach lining. The flavonoids present in DGL promote mucosal cell proliferation and inhibit inflammatory mediators. Unlike regular licorice, the glycyrrhizin is removed, allowing it to heal ulcers and soothe irritation without affecting systemic cortisol levels (Evidence Level B).

Question 2

Does DGL licorice interact with any prescription medications?

Accepted Answer

DGL generally has no significant drug interactions because the compound responsible for interactions—glycyrrhizin—is removed during processing. Whole licorice interacts with blood pressure medications and diuretics, but DGL does not carry these risks. However, patients should always consult a physician regarding potential interactions with specific anticoagulants or antiplatelet drugs.

Question 3

What is the correct dosage for DGL for acid reflux and ulcers?

Accepted Answer

The recommended adult dosage for DGL is 380–760 mg chewed 15 to 20 minutes before meals. Chewing is essential because it mixes the active compounds with saliva to coat the esophagus and stomach lining effectively. This dosage is supported by Evidence Level B for promoting the healing of gastric ulcers and managing GERD symptoms.

Question 4

Is DGL licorice safe to take during pregnancy?

Accepted Answer

Yes, DGL is considered safe during pregnancy because the glycyrrhizin, which can cause hypertension and preterm labor, has been removed. Standard licorice root is contraindicated in pregnancy, but the deglycyrrhizinated form offers digestive relief without these risks. Pregnant women should still consult their healthcare provider before adding any supplements to their regimen.

Question 5

Can DGL help heal gastric ulcers effectively?

Accepted Answer

Yes, clinical evidence (Level B) suggests DGL is effective for healing gastric ulcers. It acts as a demulcent, forming a protective barrier over the ulcerated tissue, and stimulates mucus production to shield the stomach from acid. Studies indicate it can be as effective as standard pharmaceutical treatments for promoting mucosal healing and preventing recurrence.
