A new study from the China Academy of Chinese Medical Sciences examines the 'bidirectional regulation' effect of acupuncture, proposing that therapeutic outcomes arise from the coordinated activation of two sets of independent regulatory systems rather than a single, self-contradictory mechanism. The research clarifies how acupuncture influences homeostasis across various physiological functions by engaging distinct neural pathways, stabilizing opposing states like excess and deficiency.

Why it matters

This refined understanding of acupuncture's regulatory mechanisms has important implications for both research and clinical practice. By distinguishing segment-specific from system-level effects, practitioners can design more precise treatment strategies aligned with the underlying neural pathways of disease. For researchers, the framework offers testable hypotheses that bridge traditional concepts with modern neuroscience, potentially improving experimental design and advancing the clinical standardization of acupuncture.

The details

The study systematically analyzed experimental and clinical evidence to elucidate how acupuncture recruits autonomic and central regulatory circuitry to sustain homeostasis. The authors propose a model in which different acupoints activate distinct neural circuits, collectively contributing to the stabilization of physiological set points rather than producing contradictory effects through a single pathway. The research distinguishes between 'homotopic acupoints,' which exert specific regulatory effects on target organs innervated by the same spinal segment, and 'heterotopic acupoints,' which modulate organ function across spinal segments. This framework explains why the same acupoint may appear to produce opposite clinical effects by acting on different target organs or regulatory loops.

  • The study's findings were reported in May 2025 in the journal of Acupuncture Research.
  • The research was funded by a Key Project of the National Natural Science Foundation of China (No. 82230123).

What they’re saying

“Acupuncture should not be understood as a single stimulus producing inherently opposite outcomes. Instead, its effects emerge from structured interactions between somatic inputs and autonomic regulation.”

— Study Author

What’s next

The study's findings offer a more precise framework for understanding how targeted somatic stimulation contributes to systemic balance, which could lead to the development of more effective and personalized acupuncture treatments.

The takeaway

This study provides a solid scientific explanation for the bidirectional regulatory effect of acupuncture, bridging traditional concepts with modern neuroscience. By distinguishing between different types of acupoints and their corresponding neural pathways, the research lays the groundwork for advancing the clinical standardization and experimental reproducibility of acupuncture.
