I have noticed since doing cleanses and flushes that almost all of my adjustments have been from the mid-thorasic down, with an occasional adjustment in the upper thorasic for my heart and lungs I believe.
I have known since I was 15 about the nerve relationship to organs in the bottoms of our feet, but just in the last three years began to understand the nerve relationship to organs in the spine; now I am beginning to understand this relationship in the colon and teeth/mouth. I am sure the hands have involvement as well after all our bodies survive due to these open channels of communication through our nervous system. I should study acupuncture which would give me the whole picture I am sure.
