  • Step 1: Identify DGL Identify the licorice product as DGL. DGL is processed licorice from which the natural glycyrrhizic acid has been removed. High doses of glycyrrhizic acid have been shown to cause high blood pressure, fluid retention, and low potassium levels.

  • TIP: DGL products are available for purchase online or in natural food stores.
  • Step 3: Use DGL mouthwash Use a DGL mouthwash to treat canker sores. Mix 200 milligrans of DGL powder with 200 milliliters of warm water; swish it in your mouth for two to three minutes, spit it out, and repeat three or four times per day.
  • Step 4: Treat ulcers with tincture Treat ulcers with a licorice root tincture. Take 1 teaspoon of DGL liquid root tincture three times a day; take the tincture by itself or combine it with a cup of warm water.
  • Step 5: Apply DGL cream Apply a thin layer of DGL cream or gel to areas of atopic dermatitis. Preliminary studies show the licorice helps to calm the dry, irritated skin.
