I know a person with cystic fibrosis loses salt quicker through their skin (their skin is salty), so adding extra salt as a treatment may be why.

Oh yes oddone. "Salt" therapy works for all kinds of respiratory issues. Even Empysema. There was a segment on the Doctors about a Mother and Daughter who visited a salt cave to see if it helped with their Asthma. And it worked. The Mother could go without her bronch inhaler after a few "salt" therapies. Salt Caves are popping up all over the place. Especially in Spas. People can buy portable "salt" caves and have them set up at their homes. People can also buy salt pipes and salt inhalers. You can also but "sea salt" at the supermarket and place it in boiling water and breath in the steam for about 15 minutes a day. I thought I remembered you saying you had COPD. You may find this therapy benificial.

Thank you so much, I will try the salt in boiling water. Will let you know any results later.

We has a segment on the use of SALT CAVES for Asthma on December 28, 2008...

Asthma
Nicole struggles with asthma, and now her daughter is suffering from the same condition. She is curious about holistic treatment, so The Doctors send her to the Galos Salt Caves in Chicago, Illinois, where it’s believed to cure everything from acne to asthma. After her trip, Nicole joins The Doctors in studio to report her progress.  She says the trip was therapeutic, and noticed that she has since decreased the usage of her inhaler. She says her daughter’s asthma symptoms improved as well. Dr. Sciabbarrasi, an integrative medicine specialist, says that studies show that cave treatments are beneficial. Dr. Travis says he has a problem recommending salt caves because there is no proof that they actually work.
