After decades of medical practice, Hua Tuo has mastered the treatment methods such as health preservation, prescriptions, acupuncture and surgery. He is proficient in internal medicine, surgery, gynecology and pediatrics. He can treat clinical symptoms and make accurate diagnosis. , the method is simple and the curative effect is rapid, and it is known as the "miracle doctor". Regarding this, there is a similar comment in "Three Kingdoms" and "Book of the Later Han Dynasty", saying that he was good at maintaining health ("Knowing the art of nourishing one's nature, people at that time thought that a hundred years old would make one look magnificent"), and he was good at using medicine (" There are also precise prescriptions and medicines that can be used to treat diseases. There are only a few kinds of decoctions that can be combined into one. They are divided into separate doses without weighing them. They can be boiled and drunk immediately. It is said about their temperance. If you give them away, they will heal.") Acupuncture is simple ("If it is a needle, it is In just one or two places, the needle was inserted and said, "If something comes, tell the person." The patient said, "It's already here," and "The needle will be pulled out, and the disease will also go wrong.""), the operation is miraculous ("Gu Cut open the abdomen and back, cut off the accumulation", "break the intestines and wash them with drip"). Among the medical records left behind, there are sixteen in the Chronicles of the Three Kingdoms, five in the Biography of Hua Tuo, five in other documents, and twenty-six in total, which are more among doctors in the pre-Qin and Han Dynasties. Judging from the scope of treatment, internal medicine diseases include febrile and venereal diseases, visceral diseases, mental illness, obesity, and parasitic diseases. Diseases belonging to external, pediatric, and gynecological diseases include trauma, intestinal carbuncle, tumors, fractures, acupuncture errors, lactation avoidance, stillbirth, Diarrhea in children, etc. He invented Mafei Powder, setting a precedent for anesthetic drugs in the world. Records of general anesthesia surgery in Europe and the United States began in the early 18th century, more than 1,600 years later than Hua Tuo. "History of World Pharmacy" points out that the use of anesthetics by Arabs may have been introduced from China, because "the famous Chinese doctor Hua Tuo is the best at this technique." "Sui Shu·Jing Ji Zhi" records a volume of "Moxibustion and Acupuncture in Huatuo's Pillow", which has been lost. The "Hua Tuo Acupuncture Sutra" quoted in "Yixin Prescription" may be the lost text of the book, and the "Hua Tuo Mingtang" is quoted in "Taiping Shenghui Prescription". Judging from the extant lost texts, the names and locations of the acupuncture points contained in the "Huatuo Acupuncture Classic" are quite different from those in the "Huangdi Mingtang Sutra".
