Sounds like this is actually being more and more incorporated into modern medicine (like in osteopathic medicine in the US. I have heard of innate intelligence (but rather in the context of "what is intelligence"). What I heard was that innate intelligence is the ability of the body to detect its position in space among other things (athletes would have a high intelligence).
I am not denying that spirituality is useless and bogus. Rather I would say it is misunderstood. All parts of the body communicate and people are moving away from a "brain" only view. We long know of the peripheral nervous system that is capable of dealing with certain things by itself. Recently talk of a brain-gut axis arose. We are understanding our perception better and better every day.
I believe that the aforementioned "conversation" of different tissues in our body is responsible for the link between psyche and health. I am not sure if this is an "energy" flow problem. The issue is the word "energy". These events you mention are probably due to bioelectricity and chemistry, but have not yet been described. Again, I am not saying your statement is wrong, but there is something very physical even behind these spiritual events (physical as in electrons and atoms doing something we do not know exactly what as of now).
Cheers!
