Acupuncture at Zusanli (ST36) for the benefits of sepsis-laboratory evidence for "preventive treatment of disease" and "holistic concept" in the protective effects of acupuncture: a literature review of rodent studies.

Researchers reviewed existing animal studies to understand how acupuncture at the Zusanli point (ST36), located below the knee, might protect against sepsis, a life-threatening condition where the body's response to infection causes widespread inflammation and organ damage. The review examined laboratory studies in rodents to explore why this specific acupuncture point has been traditionally used in Chinese medicine for disease prevention and overall health maintenance. The studies found that stimulating ST36 activates multiple body systems simultaneously, including the nervous system, hormone regulation, and immune responses. This stimulation appears to reduce inflammation throughout the body by triggering anti-inflammatory pathways through nerve connections and by releasing protective particles called exosomes into the bloodstream. Interestingly, some research suggests that acupuncture at ST36 may work preventively—meaning it could help protect against inflammation before disease occurs, not just treat it afterward. This supports the traditional Chinese medicine concept of "preventive treatment of disease." The researchers identified that lower-intensity electrical stimulation at this point activates disease-independent anti-inflammatory pathways, suggesting potential for preventive care applications. However, the review also highlighted important gaps in understanding exactly how these protective mechanisms work, including which nerve pathways are most important and how the protective exosomes function. While these findings are promising, they come from animal studies, so more research is needed to confirm these effects in humans. If you're considering acupuncture for inflammatory conditions or preventive care, consult with a licensed acupuncturist who can develop an individualized treatment plan.

This literature review examined rodent studies investigating ST36 acupuncture's mechanisms in sepsis-related multi-organ inflammation. Key findings indicate that ST36 stimulation modulates the neuro-endocrine-immune network and serum exosome activity, demonstrating anti-inflammatory effects in both septic and normal mice. The review identifies three critical research gaps: (1) incomplete understanding of neural circuit mechanisms, particularly regarding interdependent pathways including the sympathetic nervous system, cholinergic anti-inflammatory pathway, and vagal-splanchnic nerve axis; (2) unclear exosome dynamics regarding production mechanisms, cellular origins, and therapeutic targets; and (3) limited investigation of preventive applications despite evidence that low-intensity ST36 electroacupuncture activates disease-independent anti-inflammatory pathways. The review emphasizes the "holistic concept" of acupuncture's systemic effects and supports the traditional "preventive treatment of disease" principle. Clinical implications suggest ST36 may offer both therapeutic and prophylactic anti-inflammatory benefits through multiple simultaneous pathways, though specific sample sizes and effect sizes were not provided in this review article. Further translational research integrating neural circuit complexity and exosome biology is needed.
