Remedi was recommended by two of my health care providers. Both wanted me to use the dry salt therapy. I have severe asthma that has been difficult to control, the salt treatments have been very helpful and definitely contributed to improvement of my symptoms. They offer two options, an upright box or bed, the treatment lasts 20 to 30 minutes. You stay full clothed and just sit or lay relaxed while breathing in healthy microscopic salt particles. It has been so helpful I've continued treatments for the past 8 months. Remedi has numerous other health treatments, I've also used the hydromassage and found it helpful and very relaxing. I highly recommend REMEDI, it offers many helpful, relaxing treatment in a very clean inviroment with an exception staff.
