Nasal irrigation is an ancient health practice that originated from the yoga tradition.
During the 19th century, nasal flushing was encouraged by physicians as a method of routine
cleansing. Now, a growing body of scientific evidence shows that this practice is safe,
effective, and beneficial. It is becoming more accepted as a simple way of treating common sinus
problems caused by allergies, colds, and sinus infections.
In practice, nasal irrigation is the flushing of a warm saline solution
through the nostrils to clean out the nasal passages and to alleviate stuffiness
and nasal blockage.
