How Acupuncture Works Through the Body's Own Opioid System: The Endorphin Evidence
Decades of research confirm acupuncture releases endogenous opioid peptides (endorphins, enkephalins, dynorphins) with frequency-specific patterns, providing the definitive scientific mechanism for acupuncture's pain relief.
Quick Facts
What This Study Found
Acupuncture and electroacupuncture produce analgesia through frequency-specific release of endogenous opioid peptides: low frequency releases endorphins/enkephalins (mu/delta) and high frequency releases dynorphins (kappa), confirmed across animal and human studies.
Key Numbers
How They Did This
