All my life I had suffered from recurrent mouth ulcers, every treatment I had tried without success. Conventional medicine provides lotions to soothe the area and relieve pain but not a solution. About six months ago I decided to try the five oils (what I had to lose) from the Ophtas I suffered on a weekly basis without a break. Today, half a year later, I can say with full mouth, no more slaps! It just works! Warmly recommends to me that it certainly did only good!
