An evolutionary perspective for integrating mechanisms of acupuncture therapy

This study applies an evolutionary medicine perspective to comprehend the therapeutic effects of acupuncture. It draws upon modern evolutionary theory to integrate the currently fragmented theories regarding the efficacy of acupuncture in alleviating pain and promoting healing. We explore the interaction between the nervous and immune systems in the context of survival and homeostasis, and elucidate both the local and systemic effects of acupuncture therapy on pain relief and tissue healing. The mechanisms involved are categorized into two main types: local effects, which include immune cell migration, local vasodilation, and the release of adenosine; and distal systemic effects, which involve the regulation of the descending pain control system and the autonomic nervous system, with a particular focus on the parasympathetic nervous system. In conclusion, this integrated perspective not only deepens our understanding of acupuncture within a scientific narrative but also underscores the need for further research to validate and expand our knowledge, thereby enhancing its scientific credibility and clinical applicability.
