Claims are no good without proper scientific backup. 'Feeling' better doesn't really mean much, we need to see what's actually going on inside
Let me give you a good example. Many patients have had stem cell trials, where stem cells have been injected into heart muscle to see if dead scar tissue will have new muscle formed over it. Before the trials, every patient had an EKG, Echo, Stress Echo and Nuclear scan. After the trial, the same tests were run. We have 2 contradictory sets of results.
