The importance of the abdomen especially the dantian as an energetic centre, the fundamental source of our qi, is central to acupuncture. The extraordinary vessels originate from this area. The ren, du (internally) and the chong mai flow centrally with the dai mai encircling the whole abdomen. The deep pathways of the twelve main channels all have connections throughout the abdomen. It would seem then, that a method of directly assessing what is happening in this area, must be of tremendous clinical use. A way of diagnosing the centre itself rather than using it only for treatment. To get to the root of the problem one must literally assess the condition of the root itself.
