Licorice - Research
Licorice is one of the most extensively researched medicinal and food plants.1 Studies on licorice have demonstrated positive effects for treatment of various types of ulcers.5 Others showed that dietary consumption of licorice root extract may help to lower cholesterol and act as an antioxidant.5,6
The German Commission E approved licorice root for inflammations of the upper respiratory tract and stomach ulcers.1
Licorice extracts are used in cough drops, syrups, laxatives, and nicotine lozenges.4 The root is also added to teas.
