How Acupuncture Relieves Pain: A TCM‑Based Explanation Supported by Modern Neurophysiology
(Integrating meridian theory, qi–blood physiology, and modern pain science); Reference: Pain Reports. 2024 Sep 13;9(5): Review: “Recent advances in acupuncture for pain relief”.
Acupuncture has long been rooted in the classical TCM principle: “Where there is pain, there is blockage; when the blockage is removed, pain is relieved.” Modern research increasingly aligns with this view. The article notes that acupuncture has achieved global expansion and shows promise for both acute and chronic pain management .
Below is a TCM‑style interpretation that bridges classical theory with the mechanisms described in the article.
1. Unblocking the Meridians: Restoring the Flow of Qi and Blood
In TCM, pain arises when meridians are obstructed and qi–blood cannot circulate freely. Needle insertion stimulates meridians, disperses stagnation, and restores flow.
Modern research parallels this concept: acupuncture induces local physiological responses at the needling site , including microcirculation changes and inflammatory modulation—consistent with “opening the channels.”
2. Harmonizing Qi and Blood: Supporting Internal Balance
Qi drives function; blood nourishes tissues. When either is deficient or stagnant, pain develops.
The article reports that acupuncture triggers peripheral and central release of endogenous opioids and biochemical mediators. In TCM terms, this resembles strengthening the body’s internal healing capacity—allowing qi to move and blood to nourish, reducing pain naturally.
3. Regulating Zang‑Fu Organs: Treating Pain at Its Root
TCM teaches that organ systems influence pain patterns:
Liver qi stagnation → headaches, rib‑side pain
Kidney deficiency → low back/knee pain
The article notes that acupuncture may target sources that drive pain, such as inflammation, partly via autonomic modulation . This aligns with the TCM view that acupuncture restores organ harmony and addresses root causes—not just symptoms.
4. Calming the Shen: Pain and Emotion Share the Same Pathways
Emotional stress disrupts qi flow and worsens pain. Acupuncture helps settle the Shen (spirit), easing tension and restoring internal harmony.
Modern neuroimaging shows acupuncture modulates brain networks involved in sensory, affective, and cognitive processing . This dual effect—reducing pain and stabilizing mood—mirrors classical TCM understanding.
5. Individualized Treatment: Acupoints, Techniques, and Practitioner Skill Matter
TCM emphasizes pattern differentiation and individualized treatment.
The article similarly states that acupuncture is a complex multifaceted intervention, with efficacy influenced by acupoint selection, needling technique, stimulation method, and practitioner expertise .
Integrated Summary
From a TCM perspective, acupuncture relieves pain by:
Unblocking meridians
Regulating qi and blood
Harmonizing organ systems
Calming the mind
Tailoring treatment to the individual
From a modern scientific perspective, acupuncture works through:
Local physiological responses
Spinal and supraspinal modulation of nociceptive signaling
Endogenous opioid release
Brain network modulation
Autonomic and inflammatory regulation
Both frameworks converge on the same conclusion: Acupuncture is a safe, multi‑layered, neuromodulatory therapy that addresses both the symptoms and drivers of pain.
