The following is a snippet from a great article about acupuncture. We've noted the source below if you would like to read the entire article.
June 28, 2014 - " Researchers have discovered that acupuncture causes a special biochemical reaction that reduces inflammation and muscle pain. The study, published in Molecular Neurobiology, investigated the effects of needling one acupuncture point on the leg. The research team measured a remarkable effect. Manual acupuncture stimulation downregulated M1 macrophages (pro-inflammatory cells) and upregulated M2 macrophages (anti-inflammatory cells). As a result, acupuncture reduced pain and swelling. This neurobiological acupuncture continuing education study solves a great mystery, how does acupuncture work? The secret is in the biochemistry...This study measured responses in muscle tissues and confirmed that M1 to M2 macrophage phenotype switching is triggered by acupuncture stimulation. Acupuncture literally flips a switch wherein initial inflammatory responses are reduced and the secondary healing responses are promoted."
