NO MIXING REQUIRED!!! Rhinorinse is a pre-made nasal rinse created to increase the convenience and effectiveness of improving your nasal health. Rhinorinse has a composition similar to ocean water and our body's plasma and the composition have been shown in clinical studies to be superior to saline nasal rinses. Avoid potential contamination of using tap water or the hassle of using boiled water or distilled water. And because the solution is pre-made, you can use less of the rinse to gain benefit without the feeling of drowning or your ears being plugged.
