Bloodletting therapy, also known as “acupuncture and bloodletting therapy,” is a method of using needles or knives to pierce or cut specific acupuncture points and certain parts of the body to release a small amount of blood in order to treat diseases. The origin of this therapy can be traced back to the ancient Stone Age. At that time, people found in their labor practice that using a sharp stone acupuncture, acupuncture in the affected area to release blood, can treat certain diseases. With the development of science, metal needles were used for acupuncture, and later, according to the needs of medical practice, “sharp needles” were used specifically for bloodletting treatment. The earliest written records of this therapy are found in the Yellow Emperor’s Classic of Internal Medicine, such as “the one who pricks the liao, pricks the blood veins of the small liao”: “Ivana Chen is removed, and the bad blood is also removed”. It is also clearly stated that pricking and releasing blood from the luo can treat epilepsy, headache, mute, fever and asthma, epistaxis and other symptoms. According to legend, Bian Ji cured Prince Guo’s “corpse syncope” by releasing blood at Bai Hui point, and Hua Tuo cured Cao Cao’s “head wind syndrome” by releasing blood through acupuncture. During the Tang and Song dynasties, this therapy has become one of the major methods of Chinese medicine. According to the New Book of Tang, the imperial physician of Tang Dynasty cured Emperor Gaozong of Tang Dynasty’s “head dizziness and inability to see” with the method of bloodletting from the top of the head. In the Song Dynasty, the method was incorporated into the acupuncture song “Yu Long Fu”. During the Jin and Yuan dynasties, Zhang Zihe’s acupuncture and moxibustion cases in “Confucianism” were almost all effective in acupuncture and bloodletting, and he believed that acupuncture and bloodletting was the most rapid way to attack evil. Derived to the Ming and Qing dynasties, bloodletting has become very popular, the needle tool also developed quickly, the three prong needle has been divided into coarse, fine two, more suitable for clinical application. Yang Jizhou’s “Acupuncture and Moxibustion Dacheng” recorded the cases of 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 the “Crosstalk of the Yajia” and “Li Bo Era”.
