Acupuncture 101: Meridian Points

By Peter A.C. Garrison

According to Traditional Chinese Medicine (TCM), illness and disease are caused by imbalances or breaks in the flow of life force throughout the body. To restore its harmonious flow and health, this "qi" or life force is manipulated by the inserting fine needles into acupuncture points throughout the body. These acupuncture points are primary to the practice of acupuncture by licensed acupuncturists, and according to Traditional Chinese Medicine, there are dozens of them all over the human body.

These acupuncture points create an energetic river or system in the body according to TCM, similar to lakes and rivers. Using this water analogy, TCM likens a healthy body to a healthy water system. When there is a free flow of energy, the system of which it is a part is considered healthy. When there is blockage or stagnation of that energy, the system is unhealthy or diseased. By unblocking or strengthening the flow of qi at key points, acupuncture allows the body to heal itself.

One of the biggest obstacles to an acupuncture treatment for most people is their fear of the needles being inserted into their body. Fortunately, however, the insertion of these needles is almost entirely painless. In the hands of skilled, licensed acupuncturists, the insertion of these needles is in most cases painless. When discomfort is experienced, the sensation is similar to a mild ant bite. It is nowhere near as strong as the sensation one often experiences when donating blood.

The paths or flows of energy, called meridians, formed between acupuncture points are still being mapped out by Western science. The challenge of this task lies in the fact that the meridians don't correspond closely to the established nerve or blood pathways already mapped out by Western medicine. Some scientists are beginning to think that the meridians are located throughout the body's connective tissue.

Western scientists are also attempting to put together the mechanism by which acupuncture points affect the body. New data is suggesting that acupuncture points are actually specialized conductors of the body's biological electromagnetic signals. For example, the flow of a pain signal from a body part to the spinal cord and eventually to the brain are controlled by what Western science posits are "gates" throughout the central nervous system. Like streets and alleys, the body's nerve pathways can handle a limited amount of information or flow through its pathways.

Acupuncture helps to generate signals which move faster than the pain signals, crowding those pain signals out because of the limited capacity of the nerves. The pain signals are thus blocked from reaching the brain. The acupuncture signals may also start the flow of endorphins and other pain-reducing hormones and chemicals, or perhaps signal the immune system to pay attention to specific body parts.

Studies have also found that the stimulation of acupuncture points not only attenuates pain but also affects directly the body's circulation, blood pressure, cell production in blood, and immune system function. The points also stimulate the brain and spinal cord to release chemicals into the rest of the body which alter brain chemistry in a beneficial way.

Does acupuncture work through the body's bio-electric field? Will the meridians one day be mapped by Western tools? Whatever the answer, and whenever Western medicine finally validates the medical knowledge of TCM, there is more than sufficient evidence to show that acupuncture is as effective as Western medicine in relieving many ills and diseases. Does acupuncture do this by actually harmonizing the balance of yin and yang in the body, as TCM suggests, or by some other means? Regardless of the final answer, acupuncture produces amazing results. - 15995
