Acupuncture is the practice of inserting very thin needles at various locations on the body called acupuncture points. These points are located along a network of channels that run in certain directions where Qi (chee) is said to flow most readily. Qi is often referred to as energy, but its concept is much more complex. Qi gives us and all of nature, here and in the entire universe, life and structure. It is spoken of within the dynamic of yin and yang, a concept of duality and constant balance. Clinically we talk about Qi in the human body as having specific function within each organ system and corresponding meridian. If the flow of Qi becomes blocked, pain results. If the yin or yang of Qi becomes out of balance, pain, disease and/or dysfunction results. An acupuncturist assess the state of Qi and uses specific acupuncture points to help the body correct the imbalance and restore proper function.
