Um.  Well, I suppose it does before you are born, but what the article 
indicated was that an artery lies behind the belly button, so that shining the 
LED light on it gets to the blood stream easily.  The other place to shine the 
LED for treating the bloodstream (as opposed to various joints and organs) is 
on the wrists.  The person I was in contact with preferred the belly button 
method.
I don't know any more than I have gleaned via the net, but I can pass that on 
to you.

  Rowena,
  You were the one who emailed and said that all of your blood passes through 
the belly button.  
  I have an enhancer and I tried this I could litterly feel the blood moving to 
different parts of the body, mainly the face.
  Question?  What other acupuncture points are just as valuable???
  I have googled just about everything I could think of to get any information 
but not understanding what all of the words are I am having a hard time.

  Help.  This is good to know.
  Mary
