When I tried the green packs of salt?? I find that it burns. I usually use the larger bottle and put two packs of the blue with filtered water and war

Our green packets are hypertonic, meaning they are twice as concentrated as our isotonic solution. Some physicians do recommend hypertonic solutions in certain cases. They believe that a higher concentrated solution will draw the fluid and mucus out of congested nasal and maybe sinus openings. If you prefer higher salinity or hypertonic solution, you may use 1 hypertonic packet in 8oz of (distilled, filtered [through 0.2 micron], or previously boiled) water. The hypertonic solution may cause some burning and stinging because it is a higher concentration.
