Licorice Precautions

Special precautions & warnings:

  • In large amounts, licorice containing glycyrrhizin can cause high blood pressure, salt and water retention, and low potassium levels, which could lead to heart problems.
    • Licorice can be found with glycyrrhizin removed; the product is called DGL (for “deglycyrrhizinated licorice”). DGL products are thought to cause fewer side effects.
  • People with heart disease or high blood pressure should be cautious about using licorice.
  • When taken in large amounts, licorice can affect the body’s levels of a hormone called cortisol.
  • Pregnant women should avoid using licorice as a supplement or consuming large amounts of licorice as food, as some research suggests it could increase the risk of preterm labor.
