Will this help I have high blood pressure?

During nasal irrigation, saline rinse flows through the nasal cavity, and it is not ingested into the stomach. The rinse used in Naväge has the same amount of salt (0.9%) as in human blood and the moisture that forms on the mucous membranes. Without the use of saline (i.e., if you use plain water with no salt in it), nasal irrigation causes a painful, burning sensation, and it can injure the sensitive nasal passages. Because virtually zero salt is absorbed by the body during the nasal irrigation process, our Medical Director advises that nasal irrigation is safe for individuals who have high blood pressure or who must avoid sodium intake for other reasons.
