My husband has SEVERE asthma to the point were a couple weeks ago he was on the way to the ER. We went to see our naturopath and she gave him some steroids to see if that would get him to be able to breathe on his own. It helped for a day. He decided to try the Salt Chalet and it's been amazing. He's sleeping through the night and not having to take his inhaler! This was a man who did 2 to 3 breathing treatments a night! This has been a blessing. He continues to go 2 to 3 times a week. This is worth every penny.
