  • The significance of anti-inflammatory effect of acupuncture in analgesia is manifested twofold: The first, inflammatory nociceptive pain is a major type of chronic pain. The second, neurogenic inflammation is the mechanism by which certain acupoints or acu-reflex points (ARPs) are formed at the body surface and have short-cut connections to the pathological focus. Selecting ARPs and applying appropriate sensory stimulation or local microtrauma (affected by different needling means or stimulation parameters), combined with low-frequency electrical stimulation or the vagus stimulation in the concha region, are helpful to strengthen the anti-inflammatory and analgesic effect of acupuncture.
