Has anyone heard about the Salt Caves? saltcave.co.uk/
I have been going for two and a half years. My COPD Nurse cannot believe what a difference it has made. Since going my readings have stayed the same or improved. I also have a salt pipe (Amazon ) and have just bought Salin Plus therapy device. ( bought mine from Australia, it was cheaper than UK!). salinplus.com
I would definitely recommend the salt treatments. X
