More than 50 million Americans regularly suffer from common mouth ulcers such as canker sores, denture sores and sores resulting from braces or from biting the lip or cheek. Now researchers at the University of Washington School of Dentistry say glycyrrhiza herbal extract (GX) shows promise as the first clinically proven over-the-counter medication to speed the healing process and relieve the pain of canker sores. The herbal extract is available in a product called Cankermelts-GX, medicated discs that release medication to dissolve canker sores and mouth ulcers.
