I'm not asking for medical advise, just about the availability of culinary dead sea salt.
Since it was brought up, I would point out that nebulizing saline does not function as a bronchodilator, whose function is to open the airways, but as a airway fluid hydrating agent. I'm interested in this subject because our 9-month old has cystic fibrosis, and it has been shown that 'going to the beach' and nebulized 7% hypertonic saline improve lung function and reduce exacerbations in people with CF. Saline is thought to decrease the viscosity of the ASL, which is abnormally thick in CF.
Thanks for the responses!
