The qiization of the human body refers to the changes in the movement of qi within the human body, which promotes the functional activities of the internal organs under the action of qi. The process of qiization includes the transformation of tangible things into qi, as well as the transformation of qi into tangible substances. For example, after the intake of food through the transportation of the spleen and stomach to generate ying qi, ying qi through the heart and lungs of the transport transformation function, the formation of tangible blood. The yin and yang of the human body are transformed into each other, forming an unceasing process of qiization, which constitutes the life activity of the human body and is the essence of life. The functions produced by qiization of the human body are of great significance to the human body, such as qi’s functions of promoting, warming, defending, nourishing, and solidifying (consolidating), etc. The role of qiization spreads all over the human body, obtaining nutrients from the outside world, supplying the human body for use, and then excretes metabolic products. If the qi of the human body is abnormal, it may affect the normal function of the human body, for example, if the qi of the lungs is abnormal, the lungs cannot breathe normally, and coughing and wheezing may occur; for example, if the qi of the stomach is abnormal, it may lead to nausea (lack of appetite, reduced food intake), eructation (hiccups), and vomiting; and then, for example, if the qi of the bladder is abnormal, it may lead to dysuria (unsmooth urination) and so on.
