I'm sorry I haven't answered before now. I seldom come on the . I can't think of the name of the piece of equipment that they use & I have lost the paper I had that describes it. All I can say is it is through a chiropractic clinic here in MN. The drops are from a base product that they make up to match what it is that is showing up in their testing. That's about all I can tell you. Sorry, it's not much help. Oh, this kind of care is being provided by others out in AZ somewhere too but I have no information other than that.
