How Acupuncture Works
According to Traditional Chinese Medicine

Acupuncture works by applying a thin needle to an acupuncture point located
along the meridian - a channel like structure. Each of 14 meridians controls a
set of physiological functions of corresponding internal organs throughout
the body. Acupuncture achieves its effect by regulating "Qi" movement in the
meridian. "Qi" is a conceptual energy substance that travels in the meridians
to influence the functions of internal organs. Disruption of Qi movement and
abnormally high and low of Qi are used to explain the symptoms or
diseases. Similarly, by up-regulating or down-regulating the functions of
internal organs through "Qi", acupuncture achieves its therapeutic aims and
correct the imbalance.
According to modern biomedical research

Acupuncture works through the insertion of a thin needle to stimulate
responses of internal organs such as nerve system, vascular system,
endocrine system, and the immune response. These responses lead to the
functional adjustment of human body. For instance, acupuncture may
stimulate brain to release pain control molecules (beta-endorphin) to reduce
the pain. It may also suppress CNS to relief nausea. In other case, studies
have been shown that acupuncture is capable of regulating endocrine
functions and immune responses such as increasing the serum level of
lymphocyte growth factor (IL-2), resulting in an overall adjustment of body's
well-being. In addition, acupuncture may stimulate anti-inflammatory
responses to relief the local pain such as shoulder pain, knee pain and
muscle pain. These pains are usually the results of inflammation.
