Bloodletting therapy, also known as "acupuncture bloodletting therapy", is a method that uses needles or knives to puncture or scratch specific acupuncture points and certain parts of the human body to release a small amount of blood to treat diseases. .
The origin of this therapy can be traced back to the ancient Stone Age. At that time, people discovered in labor practice that certain diseases could be treated by using sharp stones, Bianstone, to prick the affected area and draw blood. With the development of science, metal needles were produced as tools for acupuncture. Later, according to the needs of medical practice, "sharp needles" specially used for bloodletting treatment appeared. The earliest written records of this therapy can be found in the "Huangdi Neijing", such as "The person who pricks the collaterals is to prick the blood vessels of the small collaterals": "If you prick the blood vessels, it will remove them, and bad blood will come out." It is also clearly stated that bloodletting can treat insanity, headache, violent fits, heat-induced asthma, epistaxis and other diseases. According to legend, Bian Que cured Prince Guo's "corpse syndrome" by bleeding at Baihui point, and Hua Tuo used acupuncture and bloodletting to cure Cao Cao's "head wind syndrome". During the Tang and Song Dynasties, this therapy became one of the major methods of traditional Chinese medicine. "New Book of Tang" records: The imperial doctor of the Tang Dynasty cured Tang Gaozong's "vertigo and blindness" by using bloodletting from the top of his head. In the Song Dynasty, this method was incorporated into the acupuncture formula "Jade Dragon Fu". During the Jin and Yuan Dynasties, Zhang Zihe's acupuncture medical records in "Confucian Affairs" almost all relied on acupuncture and bloodletting to achieve results, and he believed that acupuncture and bloodletting were the fastest way to attack evil spirits. By the Ming and Qing Dynasties, bloodletting had become very popular in treating diseases, and needles developed rapidly. Three-edged needles were divided into thick and thin, which were more suitable for clinical application. Yang Jizhou's "Acupuncture Dacheng" recorded the medical records of acupuncture and bloodletting in more detail; Ye Tianshi used this therapy to cure laryngeal diseases; Zhao Xuemin and Wu Shangxian collected many bloodletting therapies and compiled them into "Cuan Ya Waibian" and "Li Zun Parallel Prose". In modern times, bloodletting therapy is still widely used, especially among the people. Its value is gradually recognized and accepted by people.
