First of all, I agree with the fact that the body influences the mind, and the mind influences the body. I'm not arguing about that point. That's the reason the placebo effect works; if you think you're getting better, you may actually be getting (a little) better.
The main issue here is how these energized water claims are to be evaluated. It's all fine and well for people to report "amazing" effects after consuming energized water. But without baseline measurements and controls, such reports are scientifically meaningless. Something is amazing only if you have something else to compare it to. If energized water actually has all these effects that have been attributed to it, then it should be easy to carry out clinical trials to test them. The interesting question here is, why has no one done so? You'd think the companies producing these machines would have great incentive to conduct clinical trials demonstrating their machines' great abilities. . .
The scientist looks at a phenomenon and says, "Hey, cool! Now, can I make that (or something like it) happen again?" If the answer is no, then what can be said about that phenomenon? Answer: not much.
