The best solution out there is NasalCare's patented, 100 percent natural solution. The solution is made of mineral-rich sea salt, Aloe Vera Extract (to moisturize nasal lining), citric acid (to help smell function), and sodium bicarbonate to buffer and Ph-balance solution. The best on the market by far!
NasalCare's bottle is even better. I love that it is back wash free (anti-backwash technology allowing the solution to flow into nose, not back into bottle) so that I have the peace of mind that the solution is pure during the nasal cleaning process.
