This high-concentration of salt water acts as a solvent in the treatment of sinusitis. It flushes mucous crusts and other debris from your nose, and shrinks the membranes as it pulls fluid from them. This decongests and improves the airflow into your nose, which, in turn, opens the sinus passages. Those cilia help keep mucous flowing and prevent mucous from pooling in the sinuses. It is pooled mucous that gives bacteria a chance to grow.
Table salt contains a large number of additives.
Mix ingredients together and store at room temperature. Discard after one week. Irrigate your nose with this hypertonic saline 2-3 times per day. Always pour the amount of fluid you plan to use into a clean bowl.
