Nasal washes like this have been used for years and help to alleviate allergies, chronic sinus disease, and other nasal irritation from things like occupational dust, smog, and smoke.
Box of 100 regular blue colored packets. Premeasured packets of sodium chloride and sodium bicarbonate mixture take the guesswork out of preparing the correct isotonic solution and keep things clean. Use with 8 oz. sinus rinse bottle.
Please do not use the regular blue colored packet in Pediatric 4 oz. (120 ml.) bottle. This may result in some burning or stinging sensations. Also, we caution not to use the orange colored SINUS RINSE™ packet in 8 oz. (240 ml.) of water, as it will make a hypotonic (diluted) solution with the potential risk of significant burning. The right packet in the correct quantity of water will make an isotonic solution and will not create any burning or stinging.
