Pharmacology
Licorice contains the glycoside, glycyrrhizin which has a similar structure and activity as the adrenal steroids. Licorice has an anti-inflammatory activity similar to cortisone and has been found useful for arthritis and allergies. In addition licorice has been used for mild Addison’s disease and other adrenal insufficiencies, such as hypoglycemia. Licorice also acts like the hormone, ACTH, causing sodium retention, potassium depletion, and water retention.
Excess consumption of licorice can lead to the classic symptoms of hypertension, with edema, increased blood pressure, potassium loss, and muscular weakness. The Deglycyrrhizinated form is most often used to avoid the hypertensive side effects of the glycyrrhetinic acid in whole Licorice. Licorice and DGL have a mild laxative effect and can protect the intestinal lining by increasing the production of mucus, thus alleviating heartburn and ulcers. Licorice and DGL also have a demulcent action and have been used for coughs and other bronchial complaints.
