Yes, I wonder too. I have a new ND that has a Smachine called the Asyra. You hold to copper rods and it scans your body, detecting blockages. Not meant to diagnose, but used as a tool to pick up stuff. I am not sure if I trust it! I've been scanned for food allergy s, bacteria, parasites, chemical sensitivtys, food allergy and sensitivities and more. I just don't know if I believe it to be true.....I am now going to get some real testing to hopefully confirm some of what this machine is picking up. It is highly advanced technology, and supposed to be 99%. It is way beyond todays stuff, but again, I want some proof. Scio sounds very similar.
