Licorice root, sold as capsules and liquid extracts, comes from the licorice plant. Its active component is called glycyrrhizin.
People with hepatitis C should not take licorice without first talking to their doctors. The herb can interact with certain medications. And taking licorice over a long period of time can cause serious side effects, including high blood pressure, headache and sluggishness. Glycyrrhizin can worsen ascites, the buildup of fluid in the abdomen, a condition sometimes caused by cirrhosis.
