I've mostly used Listerine and that's pretty sharp. Meridol is different. While it is as blue as the Listerine, which I still there, but it is much milder. It does not burn in the mouth. The Meridol halitosis mouthwash tastes fresh, but I can describe the taste heavy. It is a very special own taste, not peppermint yet another taste, I know. The effect is really convincing. Despite that the Meridol mouthwash is very mild, it prevents bad breath for several hours. After rinsing remains a fresh feeling throughout the mouth. Meridol combated the bad breath causing bacteria, located mainly on the tongue. I had only doubts about the effect because the mouthwash is not as sharp as I was used to, but it surprised me. It works just as well as the sharp mouthwash. On the contrary, it seems to me healthier because it does not burn so.
