Pulse diagnosis has a long history in our country. It is a summary of the long-term medical practice experience of ancient Chinese medical scientists. Bian Que, a famous doctor from the Spring and Autumn Period and the Warring States Period recorded in "Historical Records", was famous for his proficiency in looking, smelling, asking, and palpating, especially for pulse diagnosis. Sima Qian, the author of "Historical Records", even said: "To this day, Bian Que is the one who speaks about pulse." He attributed the invention of pulse diagnosis in ancient my country entirely to Bian Que, which is not accurate. According to historical records, the origin of pulse diagnosis in our country is very ancient. For example, the legendary ancient doctors Dou Ji, Gui Yuqu, etc. have discussed pulse diagnosis. By the Spring and Autumn Period and the Warring States Period, pulse diagnosis had reached a considerable level. The important medical works "Huangdi Neijing" and the later "Difficult Classic" that began to appear at that time already had many detailed discussions on pulse diagnosis. In 1973, a large collection of medical documents - "Pulse Method" and "Yin-Yang Pulse Syndrome" - were discovered in Han Tomb No. 3 at Mawangdui in Changsha, Hunan Province. They were also valuable materials for judging diseases by pulse diagnosis. All these show that pulse theory has become an important part of ancient Chinese medicine more than 2,000 years ago. By the Han Dynasty, pulse diagnosis became more common. Another famous doctor recorded in "Historical Records", Chun Yuyi (also called Cang Gong, about 205 BC -?), studied the pulse technique from his teacher Gongcheng Yangqing for three years, and accepted Gongcheng Yangqing's biography. "Bian Que Pulse Book" given to him. It can be seen from the "medical records" (medical records) of Chun Yuyi's medical treatment recorded in "Historical Records" that he must first diagnose his pulse when seeing a doctor at that time. In "Treatise on Febrile and Miscellaneous Diseases" written by Zhang Zhongjing, a famous doctor in the Eastern Han Dynasty, it can be seen that pulse diagnosis has been widely used in clinical practice and has been further developed and improved. In the Jin Dynasty, the famous doctor Wang Shuhe synthesized the knowledge and experience of pulse studies from previous generations and wrote the book "Mai Jing", which became the earliest existing monograph on pulse studies in my country. The book divides the pulse into twenty-four types, explains each pulse condition, and describes various pulse-taking methods and pulse symptoms of various miscellaneous diseases. It further combines pulse diagnosis and diseases, making pulse science a more practical knowledge. . Since then, the number of writings on ancient Chinese pulse studies has continued to increase. Many famous doctors are proficient in pulse science. For example, Li Shizhen of the Ming Dynasty also conducted in-depth research on pulse science and wrote books such as "Binhu Pulseology" (1564 AD). According to incomplete statistics, there were no less than one hundred kinds of writings on pulse studies before the Qing Dynasty. Although there are repetitions, they still reflect the development of ancient Chinese pulse science to varying degrees. Pulse diagnosis is a diagnostic method that detects pulse changes by touching the pulse in different parts of the human body. Also known as taking the pulse, diagnosing the pulse, pressing the pulse, and holding the pulse. The formation of the pulse is closely related to the qi and blood of the organs. If the qi and blood of the organs are diseased, the blood circulation will be affected and the pulse will change. Pulse diagnosis can be used clinically to infer the progression and prognosis of the disease. In clinical practice, it is mainly necessary to grasp the time of pulse diagnosis, the patient's position, the doctor's fingering and finger strength, and the time of each pulse measurement, which is limited to no less than 50 pulse beats on each side. At the same time, it is necessary to understand the changes in the pulse condition of healthy people. In order to perform pulse diagnosis correctly. Pulse diagnosis used in ancient Chinese medicine in diagnosing diseases is a unique diagnostic method. Pulse diagnosis is one of the "four diagnoses" of traditional Chinese medicine (inspection, smell, inquiry, and palpation). It is also an indispensable objective basis for syndrome differentiation and treatment.
