Another concept within TCM is the Yin and Yang theory. Everything in nature is classified as being either Yin (cold, female, dark, liver meridian, etc) or Yang (hot, male, light, gallbladder meridian, etc). In fact, they are complementary opposites of one another. It is important to understand that the meridians are categorized into being either Yin or Yang. Under healthy circumstances, the body maintains a state of balance between Yin and Yang when Qi is moving smoothly through the meridians.
If there is an imbalance in Yin and Yang or if the movement of Qi is deficient, blocked, moving in the wrong direction, or in excess, the body may already be in a diseased state or more susceptible to illness in the future. In traditional approaches, acupuncture is used to stimulate points either along meridians or points that lie outside these pathways that may connect two meridians, to correct the imbalance and restore the flow of Qi. There are over 1,000 acupuncture points on the body.
Western medicine explains it a different way. Instead of “rivers of Qi flow", there are hormones and other bio-chemicals that compose the internal regulating system, that are either stimulated or inhibited by the hypothalamus.
Acupuncture is excellent for pain relief as it helps to increase the level of beta endorphins which lowers pain levels and gives oneself a sense of happiness and euphoria. (They’re the same hormones responsible for the so-called "runner’s high.")

Air + Food = QI e = mc2
Therefore QI is NOT ENERGY!!!!
In 1997, acupuncture needles were re-classified from "experimental" to "medical device" by Health Canada.
