One of the research studies has shown that it can improve skin conditions such as acne and eczema. A two-week study that was done on 60 adults applying a topical gel that had licorice extract showed it significantly improved their eczema.


There was another study that showed that licorice extract relieved symptoms of indigestion such as acid reflux, upset stomach and heart burn. There was a one-month study that was on 50 adults that had indigestion. They took 75mg licorice capsule twice daily and the effect was it resulted in significant improvements in their symptoms compared to the placebo group.

There was a 2-month study on 58 adults that took a daily dose of licorice root. And it revealed that it was more effective at reducing their symptoms of gastroesophageal reflux disease over a 2-year period vs common antiacids.

Larger studies on human beings are still needed to 100% validate these findings.

A 3-week study gave 66 preschool aged kids sugar free lollipops that contained 15mg of licorice root twice per day during the school week. The study showed that it significantly reduced the number of streptococcus mutans bacteria. And this is one of the main causes of cavities.
