What is Qi

Qi is an untranslatable word in the Chinese medical lexicon. It signifies a tendency, a movement, something on the order of energy. There are two main aspects of Qi. On the one hand, Qi is thought of as matter without form. When this substance is diseased certain symptoms appear. Qi is also a term for the functional, active aspect of the body. When Chinese doctors do the work of diagnosis (taking a history, feeling the pulse, etc.) they are measuring different types of Qi. When acupuncture is used, the Qi is said to be obtained and then manipulated. Qi is thus an example of the absence of the matter/energy dichotomy in Chinese medicine.

Xue is include Blood ,but is not as same as the blood. Although the red liquid that circulates throughout the body is called blood in Western medicine, that is only part of the Chinese conception of Blood. In addition to being a substance, Blood is also regarded as a force, a level of activity in the body which is involved with the sensitivity of the sense organs, as well as a deep level of the body in the progression of febrile diseases. Traditionally, it is said that Blood is manufactured in the Middle burner, using the Qi derived from the air in the Lungs and food digested by the Spleen. The major function of Blood is to carry nourishment to all parts of the body.
