How Acupuncture Works, a Western Perspective

We all know the explanation given: Qi, energy and meridians. Meridians -channels or canals where the energy (Qi – pronounced Chee) flows. But how can we explain it in a more modern, scientific way? Acupuncture as we all know uses fine hair-like stainless steel needles (no, there is not medicine in them) that are inserted in different areas of the body. Once inserted, the fun starts: a micro trauma is caused in the muscle which activates the nerves and lymphatic tissues. Immediately the body reacts by activating diverse centers in the brain: the limbic system, the thalamus, hypothalamus, amygdala and others. The immune system is activated and the creation of new muscle fibers, collagen and elastin is elicited. The endocrine system starts its job by regulating the hypothalamus-pituitary-adrenal axis, meanwhile the cardio-vascular system helps not only transporting hormones but by bringing oxygen and nutrients to the area where the needles have been inserted. Let me summarize: the needle is inserted and the central nervous system is regulated as well as the endocrine (hormones), immune and cardiovascular which at the end brings homeostasis. What about the sensation experienced once the needle is inserted? In Chinese medicine, it is called the “Arrival of Qi” (De Qi) but scientifically what happens is that different nerve categories have been activated and that is why the patient experiences numbness (the parasympathetic system is taking over), heaviness, tingling, electric sensation, swollen, or travelling sensation. Now, we all know the more or less scientific explanation of acupuncture, so in your next visit don’t be scared… all is fine and is completely normal… Enjoy your treatment!
