Differences Between DGL & Licorice Root

When herbalists talk about licorice, they aren’t referring to the sweet black candy with the same name, although licorice root was the original flavor for the candy. Licorice root, harvested from the licorice, or Glycyrrhiza glabra, plant, is an herbal remedy and food ingredient with thousands of years of use. DGL, or deglycyrrhizinated licorice, is a derivative of licorice root. While both products may be beneficial, do not use them to treat any medical condition unless directed to do so by your doctor. The FDA does not oversee herbal remedies, so quality and safety may vary from one product to the next.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Licorice Root and DGL

After drying, herbal manufacturers may grind the hard roots into a powder or make a liquid extraction. The presence of glycyrrhetic acid in licorice root is of concern because it can cause side effects in some. Through a process that removes the acid, called deglycyrrhizination, DGL results, which is still beneficial in treating some conditions. If the product does not contain glycyrrhetic acid, the label will specify “DGL Licorice.”

The “PDR” lists chronic hepatitis, cirrhosis of the liver, renal disorders, high blood pressure and a rapid heartbeat as potentially dangerous side effects associated with taking regular licorice. The risk of side effects increases with overdosing. Do not give licorice root to those who suffer from heart disease, fluid retention, kidney or liver disorders, diabetes or elevated blood pressure. In addition, do not give licorice root to pregnant women and nursing mothers, unless directed to do so by a doctor. Talk to your doctor about the potential interference of licorice products, including DGL, with any current medications you’re taking.
