@djallan I did a little more research and it appears there is no scientific research or studies. It appears from the few articles I did find from MD's that it is popular in Europe and result from a few studies should positive results. From what I read it seems it can't harm you (with that being said there is always the possibility it can) I have the bed lamp also and likewise no different but I am going to try this salt inhalation and see if anything happens there. I tired trelegy and didn't seem to be any different. Currently on Tudorza , Symbicort, albuterol, Proair, 2.5L O2, 15 mg prednisone (going on 20 years for UC but does help me breathe easy) I was on 30 but could only get down to 15 before I could feel the symptoms getting worse. I also take 1200 mg twice a day of Mucinex. Occasionally do the flute value. Stay safe out there the Dorian track seems to change every few hours. Good luck on the biopsy. Breathe easy.
