Dry salt acts like a sponge attracting foreign sunstances along its path through the respiratory tracts. The dry salt can be imagined behaving like a toothbrush that cleans the respiratory system removing the build-up of the foreign elements and the cause of various ailments and conditions. 

Inhaled dry salt particles may help to reduce inflammation in the entire respiratory tract and widen the airway passages. A clean respiratory system natually results in higher oxygen intake, increases energy, and an improved immune system. 

The dry salt particles act as an anti-bacterial agent, dissolving bacteria and pollutants lodged in the respiratory tract. These are the either coughed up or naturally expelled by the body.
