Licorice Root Extract Treats Canker Sores


What common oral condition appears as shallow ulcers of different sizes, affects one in five Americans, can be caused by food allergies and hormonal changes, and also can cause severe mouth pain?  Commonly referred to as "canker sores," recurrent aphthous ulcers (RAU) now can be treated by an extract in licorice root herbal extract, according to a study published in the March/April 2008 issue of General Dentistry, the Academy of General Dentistry's (AGD) clinical, peer-reviewed journal.


The authors examined the effects of an over-the-counter medicated adhesive patch (with extract from the licorice root) for treatment of RAU versus no treatment. After seven days of treatment, ulcer size in the group who received the adhesive patch with licorice extract was significantly lower, while ulcer size in the no-treatment group had increased 13 percent.


Licorice root extract was used as a prescribed treatment for gastric ulcers until the 1970s, according to the study. In its original form, licorice root extract has a very strong taste.  However, when combined with a self-adhering, time-release, dissolving oral patch, the taste is mild and pleasant.
