Qi is a very abstract concept that may be understood and interpreted differently in different cultures and traditions.
In TCM theory, Qi is often considered to be a manifestation of life energy or life force. It is the basic substance that maintains the vital activities of the human body, and is closely related to the physiological functions, pathological changes and methods of the human body.
Specifically, TCM believes that "Qi" is present in various parts and tissues of the human body, and runs through the meridian system. The smoothness of "Qi" will affect the health of the human body. For example, if the "Qi" does not run smoothly, it may lead to problems such as blockage of the meridians and stagnation of qi and blood, which can lead to various diseases.
In **, Chinese medicine often restores the health of the human body by regulating the operation of "Qi". This can be achieved through methods such as traditional Chinese medicine, acupuncture, massage, qigong, etc. For example, the medicinal properties of traditional Chinese medicine can affect the flow and balance of qi, acupuncture can stimulate acupuncture points to regulate the operation of qi, and qigong practice can regulate qi through breathing and body movements.
However, the concept of "Qi" has not been widely recognized and confirmed in science. It is more of a traditional theoretical model used to explain the physiological and pathological phenomena of the human body. Modern medicine is mainly based on the method of empirical science, through the study of physiological and pathological mechanisms to understand and improve diseases.
