I have a diagnosis of Oral Lichen Planus, diagnosed through biopsy, of 6 years duration. It has flare-ups and quiescent phases, but right now I am in the worst flare-up I have ever experienced. Steroid mouth washes don't help, only adding thrush to the equation, so I mostly just put up with it, eat soup, and yogurt, and hold bio yogurt in my mouth for several minutes, several times a day, as this has been the best treatment I have found so far. I have been googling (well who doesn't these days!) and I wondered if Lysander might help, it seems to be effective on mouth ulcers. Any advice?
