Acupuncture stimulates specific anatomical points with fine needles, producing measurable physiological responses that are documented in peer-reviewed research. Needle insertion activates A-delta and C nerve fibers, triggering the release of endogenous opioid peptides such as beta-endorphin and enkephalins. This is the best-established mechanism in acupuncture research. Acupuncture also reduces pro-inflammatory cytokines and has demonstrated effects on gastrointestinal motility in studies of functional digestive conditions. Research is exploring acupuncture’s effects on the gut-brain axis and the hypothalamic-pituitary axis, though the mechanisms in these areas are still being characterized and are better established for electroacupuncture than for manual needling.
The evidence base is strongest for chronic pain and headache prevention. Two 2016 Cochrane systematic reviews, the most rigorous form of research synthesis in medicine, found acupuncture at least as effective as prophylactic medication for reducing how often migraines and tension-type headaches occur in many patients. Multiple systematic reviews support its effectiveness for chronic pain. For conditions including anxiety, insomnia, and certain digestive disorders, research is ongoing and results are promising, though the evidence is less uniform and more condition-specific.
Dr. Leo’s clinical approach layers two frameworks on top of this physiological foundation. Classical Oriental medicine provides a diagnostic lens, including pattern recognition through tongue diagnosis, pulse quality, and symptom relationships, that informs how he understands the presenting condition in terms of systemic balance and organ system function. Functional medicine testing then identifies the specific biochemical and inflammatory factors at work. Together they allow Dr. Leo to build a more complete clinical picture and design treatment accordingly.
Dr. Leo holds a Doctorate in Acupuncture from Won Institute of Graduate Studies and is a Nationally Board Certified Diplomate of Acupuncture and Oriental Medicine. He completed a rigorous two-year apprenticeship with Dr. Christina Captain at the Sarasota Center for Acupuncture and Nutrition, where he trained in functional medicine, targeted nutritional therapy, and acupuncture injection therapy. His primary clinical focus is digestive health, and the downstream effects that restoring gut function produces on every other system in the body.
