Canker sores are small ulcers in the mouth caused by an assortment of viruses. A susceptibility to canker sores tends to run in families. No successful conventional treatment is available.
Proposed Natural Treatments for Canker Sores
A highly preliminary study suggests that a chemically altered form of the herb licorice known as deglycyrrhizinated licorice (DGL) may be useful for speeding the resolution of canker sores. 1 And, in a second, better designed trial employing a dissolving adhesive patch with glycyrrhiza root extract, researchers noted an improvement in ulcer size and pain compared to the use of a placebo patch.8
A product containing vitamins and minerals as well as the herbs paprika, rosemary , peppermint , milfoil, hawthorn , and pumpkin seed has been used in Scandinavia for many years as a treatment for various mouth-related conditions. A small 6-month study reported that use of this product could reduce frequency of canker sores. 2 However, two subsequent studies failed to find any meaningful benefit. 3-4
One small double-blind study found benefits with an extract of the bark of the red mangrove tree, Rhizophora mangle . 5
A study performed in Iraq reported benefits through use of a mouthwash containing 5% lactic acid. 7
One study failed to find that alpha-linolenic acid from perilla oil reduced incidence of canker sores. 6
