I'm administering 5 sessions of salt cave to my 1 year-old child and I would like to know if there are clinical evidences of this treatment effectiveness. The only "recent" evidence seems to come from the former Soviet Union, a 1999 Lithuanian study. In 2006 another USA study is related to Seasonal Affective Disorder.

Any English MD or Researcher can confirm whether it is approved by UK National Health Service?

I would ask you scientific links or attachments, not newspapers, blogs or commercial website.

Thanks
