Acupuncture Qi is so mysterious. Our acupuncturist is explaining Qi system to the foreign friend.
Acupuncture is based upon the jing luo channel network theory of the circulation of Qi. Although Qi permeates every part of the body, it tends to collect and travel along channels called "jing luo." These are the so-called "meridians" of acupuncture. The jing luo channel system connects all aspects of the body together into one network of energetic communication.
Just as water flowing through a landscape tends to seek the path of least resistance, so Qi flows through the body. The flow of Qi follows the folds and creases of the body's landscape. It follows the divisions between muscles and the clefts between muscles and bones, collecting in the small hollows and depressions of the body to form pools of Qi.
These "pools of Qi" are places where Qi is concentrated and more accessible. They are the acupuncture points, where Qi can be accessed and manipulated through the use of finger pressure (acupressure), massage techniques (Tui na; literally "pinch and pull"), dermal friction (Gua sha), cupping, moxibustion (a form of heat therapy), and, of course, acupuncture.
The successful manipulation of Qi begins by contacting the Qi in the channel at one or more of the points being needled. This is called "obtaining the Qi" and is heralded by the arrival of the "Qi sensation." The patient typically feels the Qi sensation locally around the needle site and then in adjacent areas, usually along the associated channel. It has been described as a dull, heavy, aching, or mildly electrical sensation that spreads in wave-like patterns. Most people do not find the Qi sensation to be painful or unpleasant, just unusual.
An experienced acupuncturist can usually feel the patient's Qi through the needle once it arrives at the site. Once the practitioner has obtained the Qi and successfully manipulated it, the needles are removed. The entire process can take anywhere between just a few minutes to over an hour, depending on the condition of the patient. Most acupuncture treatments last about twenty minutes.
