What is Acupuncture?

The intent of acupuncture therapy is to promote health and alleviate pain and suffering. The method by which this is accomplished, though it may seem strange and mysterious to many, has been time tested over thousands of years and continues to be validated today.

The perspective from which an acupuncturist views health and sickness hinges on concepts of "vital energy," "energetic balance" and "energetic imbalance." Just as the Western medical doctor monitors the blood flowing through blood vessels and the messages traveling via the nervous system, the acupuncturist assesses the flow and distribution of this "vital energy" within its pathways, known as "meridians and channels".

The acupuncturist is able to influence health and sickness by stimulating certain areas along these "meridians". Traditionally these areas or "acupoints" were stimulated by fine, slender needles. Today, many additional forms of stimulation are incorporated, including herbs, electricity, magnets and lasers. Still, the aim remains the same - adjust the "vital energy" so the proper amount reaches the proper place at the proper time. This helps your body heal itself.

Acupuncture is just one form of therapy used within the coherent system of healing known as Oriental Medicine. Oriental Medicine includes herbology, physical therapy, dietetics and special exercises (such as Tai Chi and Qi Gong), and is a complete medical system unto itself and is not another branch of modern Western medicine. Acupuncture evolved from principles and philosophies unique to Oriental thinking and Oriental Medicine, and is most effectively applied when done in accordance with those principles.

History of Acupuncture

Acupuncture was first discussed in the ancient Chinese medical text "Huang Di Nei Jing" (The Yellow Emperor's Classic of Internal Medicine), originating more than 2000 years ago.

During the 6th Century, improved transportation and communications within the Asian Continent led to the introduction of Chinese medicine to Japan, and along with Buddhism came in the form of religious medicine.

In the 17th century, Waichi Sugiyama, in search of a simple, painless and speedy insertion method, developed the insertion tube, a small cylindrical tube through which the needle is inserted. This insertion method is still used today by practitioners worldwide, and in Japan by over 90% of the acupuncturists.

Japanese acupuncture has been well established as the primary form of health care for over a thousand years. An acupuncturist's role was comparable to that of a modern physician. When Dutch and German medicine was introduced in the 19th century, the Western modality of medicine quickly became the dominant medical practice.

Today in Japan, acupuncture remains an integral part of the health care system, offered in conjunction with medicine. In North America, acupuncture has grown into what is now a common form of pain management therapy in many clinics and hospitals. The Washington Post reported in 1994 that an estimated 15 million Americans, or roughly 6% of the American population has visited an acupuncturist and has tried acupuncture for a variety of symptoms including chronic pain, fatigue, nausea, arthritis, and digestive problems.

In 1995, the U.S. Food and Drug Administration (FDA) classified acupuncture needles as medical instruments and assured their safety and effectiveness.

The medical community for the most part now accepts acupuncture and a growing number of medical schools, such as UCLA, include acupuncture training in their curriculum.

In 1997, the US National Institute of Health issued a report titled: "Acupuncture: The NIH Consensus Statement". It stated that acupuncture is a very useful method for treating many conditions. It acknowledges the side effects of acupuncture are considerably less adverse than when compared to other medical procedures such as surgery or pharmaceuticals. In addition, the NIH made the recommendation to U.S. insurance companies to provide full coverage of acupuncture treatment for certain conditions. This momentous advancement in the status of acupuncture in the United States has certainly influenced its status elsewhere in the world, including in Canada.

In 1997, the Ontario Medical Association officially recognized acupuncture as a 'complimentary medicine', acknowledging its broad success in treatment. As acupuncture becomes increasingly accessible to more Canadians, Doctors recommend it more and more as an effective relief for many medical conditions.

Acupuncture treatment is included in many Insurance plans. It is a sure sign of acupuncture's acceptance into the mainstream. It is also an indicator of its success.

Ancient Acupuncture Theories

The understanding of how acupuncture works has evolved with its practice, but the descriptions set down a thousand years ago have largely been retained. The dominant function of acupuncture is to regulate the circulation of qi (vital energy) and blood. Approximately 2,000 years ago, the pre-eminent acupuncture text, Huangdi Neijing (Yellow Emperor’s Classic on Internal Medicine), was written. In it, acupuncture was described as a means of letting out excess qi or blood by making holes in the body along certain pathways, called jingluo (meridians). For some of these meridians, it was advised to acupuncture in such a way as to let out the blood but not the qi; for others, to let out the qi, but not the blood. Many diseases were thought to enter the body through the skin, and then penetrate inward through muscle, internal organs, and, if not cured in timely fashion, to the marrow of the bone. By inserting a needle to the appropriate depth—to correspond with the degree of disease penetration—the disease could be let out.

Prior to the time when there were microscopes by which people could envision individual cells and before autopsies revealed the intricate structures within the body, doctors and scholars projected the internal workings of the body from what they could actually experience, which was the world outside the body. On this basis, the workings of the body were described in terms similar to those used to describe the visible world. One of the critical aspects of nature for humans living a thousand years ago, when Chinese civilization was well developed, was the system of water courses, which included tiny streams, huge rivers, man-made canals and irrigation systems, and the ocean. It was envisioned that the body had a similar system of moving, life-giving fluid. This fluid was the qi, and the pathways through which it flowed were the meridians.

Instead of discussing acupuncture in terms of letting something out of the body, physicians began describing it in terms of regulating something within the body. The flow of qi through the meridians, just like the flow of water through a stream, could be blocked off by an obstruction— a dam across the waterway. In the streams, this might be a fallen tree or a mud slide; in humans, it might be caused by something striking the body, the influence of bad weather, or ingestion of improper foods. When a stream is blocked, it floods above the blockage, and below the blockage it dries up. If one goes to the point of blockage and clears it away, then the stream can resume its natural course. In a like manner, if the qi in the meridian becomes blocked, the condition of the body becomes disordered like the flooding and dryness; if one could remove the blockage from the flow of qi within a meridian, the natural flow could be restored.

In a blocked stream, just cutting a small hole or crevice in the blockage will often clear the entire stream path, because the force of the water that penetrates the hole will widen it continuously until the normal course is restored. In the human body, inserting a small needle into the blocked meridian will have a similar effect. Just as a stream may have certain points more easily accessed (or more easily blocked), the meridians have certain points which, if treated by needling, will have a significant impact on the flow pattern. Many acupuncture points are named for geological structures: mountains, streams, ponds, and oceans.

Although this description of the basic acupuncture concept is somewhat simplified, it conveys the approach that is taught today to students of traditional acupuncture: locate the areas of disturbance, isolate the main blockage points, and clear the blockage. Of course, many layers of sophistication have been added to this model, so that the needling—which might be carried out in several different ways—can be seen to have subtle and differing effects depending upon the site(s) needled, the depth and direction of needling, and even the chemical composition of the needle (such as gold, silver, or steel). For example, some needling techniques are used for the primary purpose of increasing the flow of qi in a meridian without necessarily removing any blockage; other techniques reduce the flow of qi in the meridians. These tonifying and draining methods, as well as transference methods that help move qi from one meridian to another, are part of the more general aim of balancing the flow of qi in the body.

Ultimately, all the descriptions of acupuncture that are based on the traditional model involve rectifying a disturbance in the flow of qi. If the qi circulation is corrected, the body can eliminate most symptoms and eventually—with proper diet, exercise, and other habits—overcome virtually all disease.

Acupuncture Mechanisms of Action

Several processes have been proposed to explain acupuncture's effects, primarily those on pain. Acupuncture points are believed to stimulate the central nervous system (the brain and spinal cord) to release chemicals into the muscles, spinal cord, and brain. These chemicals either change the experience of pain or release other chemicals, such as hormones, that influence the body's self- regulating systems. The biochemical changes may stimulate the body's natural healing abilities and promote physical and emotional well-being. There are three main mechanisms:

Conduction of electromagnetic signals: Western scientists have found evidence that acupuncture points are strategic conductors of electromagnetic signals. Stimulating points along these pathways through acupuncture enables electromagnetic signals to be relayed at a greater rate than under normal conditions. These signals may start the flow of pain-killing biochemicals, such as endorphins, and of immune system cells to specific sites in the body that are injured or vulnerable to disease.

Activation of opioid systems: Research has found that several types of opioids may be released into the central nervous system during acupuncture treatment, thereby reducing pain.

Changes in brain chemistry, sensation, and involuntary body functions: Studies have shown that acupuncture may alter brain chemistry by changing the release of neurotransmitters and neurohormones. Acupuncture also has been documented to affect the parts of the central nervous system related to sensation and involuntary body functions, such as immune reactions and processes whereby a person's blood pressure, blood flow, and body temperature are regulated. Preclinical studies have documented acupuncture's effects, but they have not been able to fully explain how acupuncture works within the framework of the Western system of medicine.

According to the National Institute of Health Consensus Statement on Acupuncture:

"Acupuncture as a therapeutic intervention is widely practiced in the United States. While there have been many studies of its potential usefulness, many of these studies provide equivocal results because of design, sample size, and other factors. The issue is further complicated by inherent difficulties in the use of appropriate controls, such as placebos and sham acupuncture groups. However, promising results have emerged, for example, showing efficacy of acupuncture in adult postoperative and chemotherapy nausea and vomiting and in postoperative dental pain. There are other situations such as addiction, stroke rehabilitation, headache, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, low back pain, carpal tunnel syndrome, and asthma, in which acupuncture may be useful as an adjunct treatment or an acceptable alternative or be included in a comprehensive management program. Further research is likely to uncover additional areas where acupuncture interventions will be useful."

Increasingly, acupuncture is complementing conventional therapies. For example, doctors may combine acupuncture and drugs to control surgery-related pain in their patients. By providing both acupuncture and certain conventional anesthetic drugs, some doctors have found it possible to achieve a state of complete pain relief for some patients. They also have found that using acupuncture lowers the need for conventional pain-killing drugs and thus reduces the risk of side effects for patients who take the drugs

Despite the powerful technology available today, even the modern physicists cannot explain exactly how this ancient healing therapy works. Perhaps in the near future, the actual chemical and electromagnetic events that occur during acupuncture will be described

How acupuncture works

The mechanisms of acupuncture, though not solidly proven, have exhibited several commonly accepted effects to the body. Most notable is that acupuncture stimulates the central nervous system—the brain and spinal cord. Most people report a tingling sensation, feeling relaxed or even energized. Again, this is largely based on the individual receiving the acupuncture treatment and how he or she perceives it.

During an acupuncture treatment session, anywhere from 1 to 20 FDA-approved, metallic needles are inserted into the body, ranging from just breaking the surface to up to 1 or several inches long. The longer acupuncture needles (such as 5 to 9 inches) are inserted into areas of deeper muscle/fat layers or along, under the skin or even scalp, depending on what is being treated and the required depth or penetration. The acupuncture needles are often left in for approximately 15 to 30 minutes. Some practitioners insert needles, turn them either in one direction or the other or both, depending on what they are attempting to achieve, and these needles are inserted for perhaps 10 seconds only, removed and the same needle is used for treatment of other points on that same patient. In certain instances, needles are warmed or electrically charged after insertion. The electrical acupuncture can be used with needles or through the use of a non-penetrating probe.

People experience acupuncture differently, and rarely do they describe it as 'painful'. Unlike needles used for injections, the tip of an acupuncture needle comes smoothly to a point, instead of by way of a sharp edge. Acupuncture needles are also extremely thin—about 20 times thinner than a typical hypodermic needle used for injections. The acupuncture needles are solid and do not remove tissue as would occur with a hypodermic needle, making them safer. Some practitioners also use moxibustion and burn this on the needles during insertion. This is an herb compound that is often used.

Acupuncture also has a cupping component to it, whereby cups are heated and applied to the skin to create suction and bring blood close to the surface.

There are areas on the body that are considered a micro system and some acupuncturists may treat only those micro systems, such as treating only the ear (auriculotherapy), only the face, only the hand, only the foot, etc.

In the US, only sterile, one-time use needles (that are sealed prior to use) are allowed. After use, the acupuncture needles must be disposed in a proper hazardous waste receptacle.

During the course of the acupuncture procedure, specific chemicals release into the body, supposedly affecting back pain and neck pain physically and psychologically.
