Miao medicine has a long history, which is recorded in legends, poems and documents. Liu Xiang's "Talking about Bian Yuan Wu" in the Western Han Dynasty records: "I heard that the ancient doctor was called Miao Fu, and Miao Fu was a doctor, practicing medicine in the countryside." Ozawa (Eupatorium adenophorum) and Acorus calamus, known as Miao medicine, often appear in the documents of the Spring and Autumn Period and the Warring States Period, such as Chu Ci. About one third of Miao notes in Shennong Herbal Classic; The first volume of Compendium of Materia Medica contains 15 species, and the second volume contains 27 seedling drugs. This shows that Miao medicine penetrated into the treasure house of Chinese medicine a long time ago and was included in the pharmacopoeia of Chinese medicine books, which occupies an important position in history.

Miao medicine has a long reputation for its remarkable curative effect. /kloc-At the end of 0/9, Yi Long, the second child in Huataoting, Guizhou Province, took out the stillbirth for the pregnant woman by caesarean section. After a month of treatment, the pregnant woman recovered, which was a sensation and an anecdote. Leishan Miao Medicine is handy for poisonous snake injury, and can cure furuncle, carbuncle, gangrene, snake venom, arthritis, rheumatism, rheumatoid and other diseases that can kill people in a short time. Hunan's "phoenix hall record" records that "Miaodi produces more drugs, either swallowed or applied, which is very effective." Therefore, military and political officials attached great importance to Miao doctors after the Qing Dynasty. For example, in the same year of Xi 'an, the rebel army led by huangping county Pan accused Nerijiang of treating knife wounds and gunshot wounds for the rebel army; Xiong Xiling, Premier of Beiyang Government, visited his hometown Xiangxi for many times to invite Miao doctors to Beijing for treatment. During the Long March, Comrade He Long attached great importance to Miao doctors and repeatedly instructed "not only to find good Miao guides, but also to mobilize Miao doctors to advance with the troops". After the founding of New China, Miao medicine was further developed, and many prescriptions for difficult diseases were discovered and developed.

Miao people live in scattered places and there are many dialects, which leads to great differences in the content of Miao medicine and presents a colorful style. For example, on the basis of the common characteristics of Miao medicine theory "thirty-six diseases, seventy-two diseases and forty-nine turns", "thirty-six meridians and seventy-two diseases" were formed in northeastern Guizhou, "two classes and five meridians, thirty-six diseases and seventy-two diseases" were used in southeastern Guizhou, and "forty-nine turns" was widely used in some areas in eastern Guizhou.

In terms of etiology and pathology, Dr. Miao believes that the stomach is the most important organ of the human body, and the stomach governs everything. At the same time, it is clearly pointed out that abnormal emotions are one of the pathogenic factors. Miao doctors in southeastern Guizhou divide diseases into two categories: cold syndrome and fever, and also divide diseases into cold meridian, hot meridian, fast meridian, slow meridian and semi-meridian according to different manifestations and bad luck. This is undoubtedly Miao doctor's in-depth understanding of the etiology and pathogenesis of the disease. Miao doctors in western Hunan believe that poison is the general cause of many diseases. As the four methods to cure poison, detoxification, showing poison and attacking poison are at the top of all laws. This is the academic view of Miao doctor's clinical poisoning first.

"No disorder, no disease". This is a summary of Miao medical mechanism. "Chaos" refers to the disorder phenomenon caused by the destruction of some tissues and structures of human body. Treatment should not only pay attention to the "poison" of the total cause, but also pay attention to the "disorder" of the total pathogenesis. In some cases, as long as the "chaos" is cured first, its "poison" often disappears without treatment. Therefore, among the seventeen methods of treating Miao diseases, the method of treating "chaos" accounts for the largest proportion. This is the methodology of "treating disorder as the foundation" in Miao medicine clinic.

In the diagnosis of diseases, Miao medicine diagnosis is similar to traditional Chinese medicine, but each has its own characteristics. In the four consultations of Miao doctors, visiting is very important and its characteristics are very obvious. For example, the fifteen-visit method in zhijin county, Guizhou, is to look at the shape, four hairs (hair, eyebrows and eyelashes), nails and palms. This method has the same similarities with traditional Chinese medicine, but it has its own characteristics. For example, Chinese medicine generally only looks at hair and looks at other three hairs less; Miao doctors pay attention to nails, which are mostly used in obstetrics and gynecology; Another example is looking at fingerprints. Miao doctors in traditional Chinese medicine should observe the color and length of fingerprints, but Chinese medicine should observe the ups and downs to determine the exterior and interior, and Miao doctors should observe the morphology to determine the etiology and attributes. The combination of the two has certain practical significance for improving the correct rate of clinical diagnosis.

Miao doctor is very particular about taking pulse diagnosis. Some Miao doctors classify the pulse as 1 1. The number of pulses is less than that of traditional Chinese medicine, but the parts of pulse taking are more than that of traditional Chinese medicine. There are various methods of pulse diagnosis throughout the ages. The earliest method of pulse diagnosis is the three-knocking and nine-waiting method recorded in Huangdi Neijing.

The smell diagnosis of Miao doctors is rarely used, and it is mainly used for vomiting, diarrhea, abnormal urine and other diseases. In addition, the diagnosis of Miao medicine in some places is very unique, mainly including blood diagnosis, emergency diagnosis and biological diagnosis. Miao doctors divided all diseases into two categories: cold disease and fever, so they formulated two principles: treating cold disease with heat and treating heat with cold. The treatment methods of diseases are mainly internal treatment and external treatment. A Miao doctor summed up the three principles of treating diseases, that is, improving the good structure of the human body, adjusting the physiological functions of the human body and supplementing the substances needed by the human body. According to these three principles, they formulated the 17 principle of treating diseases.

According to the investigation, there are more than 28 10 species of medicinal plants and more than 0/000 species of Miao medicine in Guizhou. Since the founding of New China, especially since the Third Plenary Session of the Eleventh Central Committee, Miao medicine research has developed rapidly.
