In Chinese medicine, meridians are "rivers of energy" that course through our bodies. They form a map that enables acupuncturists to determine treatment strategies for helping their patients heal. There are 71 meridians, of which 12 of which are specifically related to organs such as the Heart, Liver, Spleen, Kidney and Lung.

According to Chinese medicine, when energy is blocked, we have pain and disease. When energy flows, we have health. It is the job of an acupuncturist to determine where the energy is blocked, and to help unblock the energy so the body can go about healing itself.

The Liver meridian has five primary functions. It stores blood, maintains the free flow of the qi (energy), dominates the tendons, manifests in the nails, and opens into the eyes. Liver is associated with the Wood element. The primary emotion associated with the Liver is anger, and the personality type is the Type A personality.
