Do any of you have alternatives that might work on oral lichen planus, a reader asked last time. She’s been advised to take steroids, which she would like to avoid if at all possible. Try a few drops of citricidal in water as a mouthwash, especially after brushing your teeth at bedtime, says one reader. She keeps her toothbrush in the solution as you could otherwise keep reinfecting your mouth. One reader’s problem disappeared after he started using Neways’s toothpaste and mouthwash. It also cleared up his mouth ulcers. Another reader is persevering with a herbal preparation of Commiphora molmol (myrrh). Put five drops of the solution in water, and use as a mouthwash before swallowing. This should be repeated three times a day. Avoid smoking and drinking alcohol, and hot and spicy foods.
