What is Acupuncture?
Acupuncture is the insertion of very thin, filiform (solid) needles into various "points" on the body, chosen according to Traditional Chinese Medicine diagnostic techniques. The needles we are most familiar with are those used for injecting fluids/medications -- for this purpose, they must be hollow, and much larger in diameter than acupuncture needles. Acupuncture needles are hair-like and flexible -- they may have a brief sting when inserted, but we are neither putting anything into the body or taking anything out. It is basically a painless process.
The human body was mapped out many centuries ago by the Ancient Chinese Masters (and the Ayurvedic Masters did the same thing) into channels or meridians, most of which run length-wise along the body. It represents our body as sort of an electrical grid, with each point representing a switch or a fuse. Even in my yoga practice and teaching, I frequently will remind my students to "plug in" to the ground wherever their body is touching -- and this does help to "ground" and center us. In Acupuncture, the needles do the work of connecting, re-connecting and repairing connections in your nervous system. It is a passive experience, but very much like a "reboot" of your whole Self.
Our brain runs on electrical impulses, so it makes sense that the insertion of a small stainless steel needle under the skin, naturally creates an electrical reaction. The needles help to re-direct our energy, either stimulating or calming the central nervous system, as needed, and thereby facilitating the body-mind to heal itself.
In Traditional Chinese Medicine and Acupuncture, each channel corresponds to a specific organ system and its functions. And each point on each channel has certain actions and effects that it controls, however, it's when you combine them together in various "point prescriptions" that the medicine really begins to work. When all of your circuits/fuses are healthy and fully functioning, your grid will light up just fine! And you will feel great -- most people experience a deep sense of well-being and peace during and for some time after each treatment.
Acupuncture is part of the whole "system" of Chinese Medicine, which involves not simply learning and memorizing the 360+ points on the body -- where they are located anatomically, what their functions are separately, and then all of the many actions and effects they have when combined -- but also how to determine which points to use and when; how to insert the needles (the angle, direction and if any stimulation should be used) and how often to administer for the best outcome. In order to figure this out, a practitioner must also train and become proficient in how to diagnose the root cause of the main complaint or disease. This is the foundation for deciding which points to incorporate. It is also the safest and most effective way to select herbal remedies for each patient.
