Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
The water should not be tap water, which may contain small amounts of bacteria that are safe to drink but may be dangerous in the nose. The water should be sterile or filtered for micro-organisms; if tap water is used it should be boiled and cooled. [4] Saline solution is also sometimes used. [2]
They provide the cells with water and inorganic ions, while maintaining a physiological pH and osmotic pressure. [2] Sometimes glucose is added as an energy source and phenol red is used as a pH indicator. In medicine, balanced salt solutions can be used as an irrigation solution such as during intraocular surgery and to replace intraocular fluids.
Just keep in mind that you'll need to use distilled, sterile, or previously boiled water, per the U.S. Food and Drug Administration (FDA). (Tap water isn’t safe to use as a nasal rinse because ...
