The symptoms are; Small grey saucer-shaped sores, a surrounding red tender halo, pain on talking and eating. Large ulcers cause pain in the underlying muscle and enlarged lymph glands.
Cabbage juice speeds the healing of the mouth and peptic ulcers. Sip 7-10 fl oz daily, freshly juiced with a handful of mint leaves for added healing and improved flavor. Hold each mouthful in contact with the ulcers for as long as you can before swallowing. Three major antioxidant vitamins A, C, and E work together to boost immunity and strengthen the mucous membranes. Beta-carotene from which the body manufactures vitamin A is found in brightly colored fruits.
Aloe vera can be used to make a mouthwash to combat sore mouth ulcers. Mixed the juice with boiled water and gargle.
Boil a handful of carrot leaves in 300 ml of water for 5 minutes, let it cool slightly and use as a gargle and mouthwash.
You can also dip a cotton bud in pure clove or tea tree oil and apply neat to ulcers several times a day. Add a single drop of essential oil of rose, clary sage, geranium or savory tumbler of tepid water and use as mouthwash.
