Why Acupuncture?

Acupuncture involves the insertion of extremely thin needles through your skin at strategic points on your body. A key component of traditional Chinese medicine, acupuncture is most commonly used to treat pain.

Acupuncture has been used for thousands of years to prevent, treat and heal many ailments of the human body, mind and spirit.

Based on holistic philosophy, one ailment may affect other parts of the body that the patient may not even realize. In Traditional Chinese Medicine (TCM) the entire body is addressed, not just the isolated problem.

Many Western practitioners view the acupuncture points as places to stimulate nerves, muscles and connective tissue. This stimulation boosts your body's natural painkillers and increases blood flow.

How Does It Work?

Acupuncture effects every major system of the body, including the cardiac, gastrointestinal, circulatory, cerebral, genitourinary, endocrine and immune systems. It would take an entire book to describe all of the mechanisms involved, and in fact there is such a book for those who are interested in that level of detail. In this post my purpose is to summarize that research in a way that’s easy for lay people to understand, while providing links to more technical resources for medical professionals and others that might be interested.
Broadly speaking, acupuncture has three primary effects:
It relieves pain.
It reduces inflammation.
It restores homeostasis.
The following is a list of mechanisms that have been identified so far:
Acupuncture promotes blood flow. This is significant because everything the body needs to heal is in the blood, including oxygen, nutrients we absorb from food,
immune substances, hormoes, analgesics (painkillers) and anti-inflammatories. Restoring proper blood flow is vital to promoting and maintaining health. For example if blood flow is diminished by as little as 3% in the breast area cancer may develop. Blood flow decreases as we age and can be impacted by trauma, injuries and certain diseases. Acupuncture has been shown to increase blood flow and vasodilation in several regions of the body.
Acupuncture stimulates the body’s built-in healing mechanisms. Acupuncture creates “micro traumas” that stimulate the body’s ability to spontaneously heal injuries to the tissue through nervous, immune and endocrine system activation. As the body heals the micro traumas induced by acupuncture, it also heals any surrounding tissue damage left over from old injuries.
Acupuncture releases natural painkillers. Inserting a needle sends a signal through the nervous system to the brain, where chemicals such as endorphins, norepinephrine and enkephalin are released. Some of these substances are 10-200 times more potent than morphine!
Acupuncture reduces both the intensity and perception of chronic pain. It does this through a process called “descending control normalization”, which involves the serotonergic nervous system. 2 I will explain this process in further detail in the next post.
Acupuncture relaxes shortened muscles. This in turn releases pressure on joint structures and nerves, and promotes blood flow.
Acupuncture reduces stress. This is perhaps the most important systemic effect of acupuncture. Recent research suggests that acupuncture stimulates the release of oxytocin, a hormone and signaling substance that regulates the parasympathetic nervous system. You’ve probably heard of the “fight-or-flight” response that is governed by the sympathetic nervous system. The parasympathetic nervous system has been called the “rest-and-digest” or “calm-and-connect” system, and in many ways is the opposite of the sympathetic system. Recent research has implicated impaired parasympathetic function in a wide range of autoimmune diseases, including arthritis, lupus, rheumatoid arthritis and inflammatory bowel disease.
