More studies are needed before it is proven that the compounds effectively fight cavities in humans, caution Qing-Yi Lu, Ph.D., a chemist at UCLA's School of Medicine, and Wenyuan Shi, Ph.D, a microbiologist at UCLA's School of Dentistry. If further studies show promise, the licorice compounds could eventually be used as cavity-fighting components in mouthwash or toothpaste, they say.
Licorice has been an important herb in Chinese medicine for many years and is now being rediscovered by Western medicine as a rich source of potentially beneficial compounds. In addition to being used as flavoring and sweetening agents in candy, tobaccos and beverages, compounds derived from licorice root have been shown to help fight inflammation, viruses, ulcers and even cancer, according to the researchers.
