Essence and qi refer to the basic substances that constitute the human body and are the material basis of various functional activities of the human body. Among them, essence refers to fine substances with reproductive function, and qi refers to various gaseous substances inside the human body, such as oxygen and carbon dioxide.
Body fluid refers to a liquid substance in the human body, which has the function of moistening and nourishing the body. Blood vessels refer to the blood circulation system of the human body, which is responsible for transporting oxygen and nutrients to all parts of the body and bringing waste and carbon dioxide back to the lungs and kidneys for excretion.
In Huangdi Neijing, these concepts are used to describe the physiological processes and life phenomena inside the human body, which is of great significance to the theory and clinical practice of traditional Chinese medicine. In addition to the above concepts, the original text also mentioned the methods of keeping in good health, such as quietness and nothingness, obeying the true qi and hiding the spirit. These methods tell people to keep their inner peace, reduce their desires and follow the laws of nature in order to keep their health and mental peace.
I have a background of essence, body fluid and blood vessels;
The background of the sentence that Yu Wenren has essence, body fluid and blood vessels can be traced back to the medical classic Huangdi Neijing in the Spring and Autumn Period and the Warring States Period. Huangdi Neijing is one of the earliest medical classics in China, covering many aspects such as TCM theory, diagnosis, treatment and health preservation. In this classic, the author expounds the physiology, pathology and treatment of human body in detail under the pretext of the dialogue between Huangdi and Zeebe.
In The Theory of Ancient Innocence, the first article in Huangdi Neijing, Huangdi asked Qi Bo about human life process and physiological phenomena. Qi Bo explained in detail the various components of the human body and their roles in life activities. Among them, essence, qi, body fluid and blood are one of the most important substances in human body.
Huangdi Neijing corresponds these material compositions and life processes in the human body with philosophical concepts such as Yin-Yang and Five Elements in nature, and constructs a complete theoretical system of traditional Chinese medicine. At the same time, Huangdi Neijing also provides people with health care methods and guidance, which has become an important basis for TCM theory and clinical practice.
