Particularly important in acupuncture is the free flow of Qi, it is commonly translated as “vital energy”. Acupuncture treatment regulates the flow of Qi, tonifying where there is deficiency, draining where there is excess, and promoting free flow where there is stagnation. An axiom of the medical literature of acupuncture is “no pain, no blockage; no blockage, no pain.” Acu is based on the idea of representing an ill sound organism full with blockages that eventually will heal by “pressing” specific points (speakers).
