At the Asheville Salt Cave and Spa, people find relief from a number of ailments, like acne, allergies, arthritis, and cystic fibrosis.
News 13 spoke to one of their clients, Kim Moran, about how regular sessions in the salt cave changed her life.
Moran says she's suffered from debilitating asthma for most of her life.
But now, surrounded by 20 tons of pure pink salt for 45 minutes once a week, she told us her life has drastically changed.
"I wheezed all of the time. I had difficulty breathing. Even walking up stairs was difficult for me," Moran said. "But, I started coming to the salt cave and all of a sudden I could breathe again."
Now, without any form of prescribed medication or inhalers, Moran says she is able to live her life without losing her breath and is doing things she never thought she'd be able to do.
"I can now hike three or four miles easily without having any issues with my breathing. I work in a two-story office building. Instead of taking the elevator, I'm up and down the stairs 50 times a day," Moran said.
"My breathing is just open, my lungs are open," she added.
As to how it all works, Dr. Norman Edelman, the Senior Scientific Adviser to the American Lung Association, has said inhaled salt could perhaps thin mucus in the airway, making it easier to raise.
However, The American Lung Association added that there is no evidence-based findings to create guidelines for patients and clinicians on salt therapy, and it should be discussed with your doctor.
