The Concept of Blood (Xue) in TCM Acupuncture Theory

The concept of Blood (Xue) as it is used in Traditional Chinese Medicine theory comprises a host of different meanings, actions and effects than they way the term is commonly understood in western medicine. Chinese medicine states that the Blood is a dense form of body fluids that have been acted upon and enegized by Qi. The Blood of Chinese medicine flows both within the blood vessels as well as within the meridians, as it has a synergistic relationship with Qi. From a clinical perspective, these relationships indicate a broad spectrum of influences that must be considered when forming a TCM diagnosis. While conditions such as uterine bleeding have more obvious links to the Blood, an unsteady mind as it may arise in such conditions as depression and anxiety may also be strongly related.
