Acupuncture is one of the oldest, most commonly used systems of healing in the world. Originating in China some 3,500 years ago, only in the last three decades has it become popular in the United States. In 1993, the Food and Drug Administration estimated that Americans made up to 12 million visits per year to acupuncture practitioners and spent upwards of half a billion dollars on acupuncture treatments.

Traditional Chinese medicine hold that there are as many as 2,000 acupuncture points on the human body, which are connected by 20 pathways (12 main, 8 secondary) called meridians. These meridians conduct energy, or qi (pronounced “chi”), between the surface of the body and its internal organs. Each point has a different effect on the qi that passes through it.

Qi is believed to help regulate balance in the body. It is influenced by the opposing forces of yin and yang, which represent positive and negative energy and forces in the universe and human body. Acupuncture is believed to keep the balance between yin and yang, thus allowing for the normal flow of qi throughout the body and restoring health to the mind and body.

Several theories have been presented as to exactly how acupuncture works. One theory suggests that pain impulses are blocked from reaching the spinal cord or brain at various “gates” to these areas. Since a majority of acupuncture points are either connected to (or are located near) neural structures, this suggests that acupuncture stimulates the nervous system.

Another theory suggests that acupuncture stimulates the body to produce narcotic-like substances called endorphins, which reduce pain. Other studies have found that other pain-relieving substances called opiods may be released into the body during acupuncture treatment

Unlike hypodermic needles, acupuncture needles are solid and hair-thin, and they are not designed to cut the skin. They are also inserted to much more shallow levels than hypodermic needles, generally no more than a half-inch to an inch depending on the type of treatment being delivered.

While each person experiences acupuncture differently, most people feel only a minimal amount of pain as the needles are inserted. Some people reportedly feel a sensation of excitement, while others feel relaxed. If you experience significant pain from the needles, it may be a sign that the procedure is being done improperly.

When practiced by a licensed, trained acupuncturist, acupuncture is extremely safe. As a system of health care, acupuncture already has some inherent safeguards. Because the treatment is drug-free, patients do not have to worry about taking several doses of a medication or suffering a possible adverse reaction.

Properly administered, acupuncture does no harm. However, there are certain conditions you should notify an acupuncturist about before undergoing treatment. If you have a pacemaker, for instance, you should not receive electroacupuncture due to the possibility of electromagnetic interference with the pacemaker. Similarly, if you have a tendency to bleed or bruise easily, or if you are a hemophiliac, you may want to consider a different type of care.

In the late 1970s, the World Health Organization recognized the ability of acupuncture and Oriental medicine to treat nearly four dozen common ailments, including neuromusculoskeletal conditions (such as arthritis, neuralgia, insomnia, dizziness, and neck/shoulder pain); emotional and psychological disorders (such as depression and anxiety); circulatory disorders (such as hypertension, angina pectoris, arteriosclerosis and anemia); addictions to alcohol, nicotine and other drugs; respiratory disorders (such as emphysema, sinusitis, allergies and bronchitis); and gastrointestinal conditions (such as food allergies, ulcers, chronic diarrhea, constipation, indigestion, intestinal weakness, anorexia and gastritis).

In 1997, a consensus statement released by the National Institutes of Health found that acupuncture could be useful by itself or in combination with other therapies to treat addiction, headaches, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, lower back pain, carpal tunnel syndrome and asthma.

Other studies have demonstrated that acupuncture may help in the rehabilitation of stroke patients and can relieve nausea in patients recovering from surgery.

As with most health practitioners, the first visit to an acupuncturist usually begins with the practitioner taking a detailed history. Since traditional Chinese medicine takes a more holistic approach to patient care than Western medicine, you may be asked questions that appear unimportant (questions about your sleep habits, your ability to tolerate heat or cold, your dietary habits, etc.) but are actually vital to the type of care you will receive.

After reviewing your history, the practitioner will begin diagnosing your ailment. Depending on your condition, you may be subjected to an examination of the tongue, as well as an examination of the pulse  a major diagnostic technique in traditional Chinese medicine.

Using all of the information obtained during the history and diagnosis, the practitioner will then determine the cause of your symptoms. Depending on the condition, needles will be inserted into specific acupuncture points on the body. The acupuncturist may use moxa or electrical stimulation to enhance acupuncture’s therapeutic effect.

Depending on the seriousness and the length of your condition, your first visit may take between 30-60 minutes. It may take several visits to see significant improvement or cure your condition. As with any treatment plan, however, make sure that your questions are answered completely, and that the treatment plan seems viable and reasonable. If you don’t understand a particular technique or type of treatment, make sure to ask.
