Why can acupuncture treat pain?
Acupuncture, an integral part of traditional Chinese medicine, has been used for three thousand years to treat disease and relieve pain. By piercing some specific points on the surface of the human body with special metal fine needles, certain therapeutic purposes can be achieved.
In the Chinese medical book "Huangdi Neijing", there was a discussion of "taking pain as the acupoint", that is, where there is pain, the needle should be inserted there. In addition, the "Huangdi Neijing" also has a discussion of "selecting acupoints along the meridians", and acupuncture is placed on the acupoints far away from the pain site, and the analgesic effect is achieved by dredging the meridians.
Analgesic Mechanism of Acupuncture
Acupuncture works on various parts of the central nervous system, including the spinal cord, brainstem, cerebral ganglia, and cerebral cortex, to relieve pain. The central mechanisms of acupuncture action include neurohumoral and neurotransmitters, which are involved in analgesia.
• At the level of the spinal cord, spinal opioids, glutamate, norepinephrine, and serotonin are key elements of acupuncture analgesia.
• At the brain level, endogenous opioid peptides, the limbic system play an important role in regulating analgesia.
Various studies on acupuncture have shown that acupuncture analgesia is initiated by stimulating the small afferent sensory nerve fibers that innervate the muscles. These signals then send impulses to the spinal cord, ultimately affecting the supraspinal centers.
