Licorice Root Nutritional Information
Licorice root--also known as licorice, liquorice, sweet root and gan zao--is mostly grown in Greece, Turkey and Asia. Licorice root contains the compound glycyrrhizin, which is most beneficial part of the licorice root. Licorice root has been used traditionally in both Western and Eastern parts of the world. It is important to note that licorice root is not the same thing as licorice candy, which often contains little or no licorice root and is usually flavored by anise.

Clinical Trials
-
A few clinical trials have determined that glycyrrhizin may reduce complications in hepatitis C patients. Some traditional doctors, however, are wary that there is not enough evidence to support the claim that glycyrrhizin is a viable option for hepatitis C patients. There is also minute evidence from clinical trials that licorice root is beneficial for stomach ulcers.
Forms
-
Licorice root is available in many forms. It can come peeled and dried into a powder or come in capsules, tablets or liquid extracts. It is also available without glycyrrhizin. This product is called deglycyrrhizinated licorice or DGL.

Uses
-
Licorice root is used by herbalists to treat stomach ulcers, bronchitis and sore throat. It also can be used to treat viral infections.
Much like Saint John's wort, licorice root contains antidepressant compounds. Herbalists recommend licorice root as an alternative to St. John's wort; however, long-term use is not recommended.
One of the most beneficial compounds of the licorice root is glycyrrhizin, or glycyrrhetinic acid. It is this acid that contains antiviral agents. It has been shown to inactivate the Herpes simplex virus as well as to promote resistance to candida. However, glycyrrhizin has been shown to cause multiple side effects. It is for this reason that licorice root should not be used continuously for more than four to six weeks.
Dosage
-
Whole licorice root dosage is 5 to 15 milligrams daily. Prolonged use at these levels is not recommended. Users should be monitored by a physician.
The normal dosage of deglycyrrhizinated licorice is two to four 380 mg capsules daily. The capsules should be taken before eating and at bedtime. DGL is much safer for use than whole licorice.
Warnings
-
The glycyrrhizin in licorice root when taken in large amounts can cause high blood pressure, water retention and heart problems.
Licorice root should not be taken with diuretics or medicines that reduce potassium levels. Taking licorice root with these medicines can cause low potassium levels, which can be fatal.
The prolonged use of licorice root can affect hormone levels of cortisol. This can cause interference with steroid drugs like prednisone.
Women who are pregnant should avoid taking licorice root supplements because they can cause preterm labor.
Always consult a physician before taking any supplemental medication.
