Aphthous ulcers (canker sores) are commonly related to stress.
Hence the nickname “stress ulcers”.
Stress can suppress the body’s immunity by raising levels of naturally produced steroids in the blood. This can result in a number of disorders including mouth or aphthous ulcers. These ulcers are usually quite painful, often multiple and do not respond to orthodox medical treatment. They are not due to infection. (See figure)
Although they usually disappear spontaneously in about 10 days without treatment, they can persist or frequently recur in a percentage of patients. Because wheatgrass is a potent anti-inflammatory agent, it can be quite effective first in relieving pain and secondly in reducing the duration and frequency of occurrence of aphthous ulcers.
Hold a small amount of wheatgrass extract in your mouth for a minute, two or three times a day if possible. It often eases or eliminates pain.
