The composition is quite simple and completely natural (you can do it yourself if you know the proportions). Breath freshening medium, mint flavor is not strong. It feels hydrogen peroxide, but it's bearable for me, not disgusting, the more, knowing his favor. I tried to brush your teeth properly. In single rinse daily missing for almost a month. Expensive.
