SinuSalt is a preparation for making nasal irrigation liquid.
Traditionally, nasal cleaning liquid was prepared dissolving table salt in water. However, refined table salt includes up to 10% of substances for preventing clumping (aluminium hydroxide, ferrocyanides), silica and other additives like iodine and fluorine that irritate the sensitive nasal mucosa. An alternative for said liquid could be saline physiological solution obtainable in pharmacies, but this is not advisable either because it lacks ions (Ca++, K+) present in the mucosa and is critical for the ciliary function.
Various studies have demonstrated that, in contrast with the physiological saline solution, the Locke Ringer saline solution is the best for maintaining the activity of the nasal cilia both in experimental models and clinical trials.

SinuSalt is a combination of chemically pure salts specially formulated to make a Locke-Ringer solution specifically for nasal irrigation. It produces a solution with a salt concentration similar to that existing in the nasal mucosa. In addition, it is slightly alkaline to facilitate the fluidification of the mucus and soften the chlorine existing in tap water. Other components of SinuSalt is xylitol, a vegetable sugar obtained from fruits and trees, which is highly hygroscopic and also has anti-adherent properties against bacteria and fungi.
