Itchy and inflamed skin (eczema),there is some evidence that applying licorice to the skin can improve symptoms of eczema. Applying a gel containing licorice three times daily for 2 weeks seems to reduce redness, swelling, and itching.
Heartburn (dyspepsia), research suggests that taking specific combination products containing licorice root seems to improve symptoms of heartburn. Also, using another combination product containing licorice improves heartburn 40% more when compared to other treatments.
Recovery after surgery,research suggests that sucking on a single lozenge containing licorice 30 minutes before having a tube inserted through the mouth into the trachea reduces cough following surgery by about 50%. Also, gargling with a licorice fluid before intubation reduces complications when the breathing tube is removed.
