Neti pots use normal saline to rinse the nose of excess mucous. Normal saline is water to which salt is added and has the same degree of saltiness as your body's fluids. Saline rinses temporarily relieve nasal stuffiness (congestion) and soothes the irritated cells that line the nose. Saline dissolves dry, sticky nasal crusts and helps the nose clear these secretions.

You can achieve the same effect with a hot shower or a steam bath, but it may be more convenient to use the neti pot several times a day. The major danger from a neti pot is getting your clothing wet. Nevertheless take the precaution of thoroughly cleansing the pot after each use to prevent the growth of bacteria in the pot and especially on the tip that enters your nose.
