Vomiting is one of the eight methods of Chinese medicine, and it is regarded as an important means of expelling the evil directly from the body, together with sweating and diarrhea. The vomiting method is divided into oral medication to induce vomiting, medication blowing nose to vomit, objects and equipment to explore vomiting and other methods. Oral drugs to induce vomiting and drugs blowing nose to vomit are the use of drugs to achieve the vomiting method. Chinese medicine has a long history of research and application of this type of drugs, prescriptions. The famous physicians who are skilled in this method have emerged from generations. Drug blowing nose to vomit refers to the use of spicy drugs such as blowing into the nasopharynx to cause radioactive vomiting. Object probing is to induce vomiting by constantly probing the posterior pharyngeal wall of the patient with a probe. It is often used in combination with pharmacologic emetics. Vomiting method caused by the intense movement of the stomach and intestines, both excretion of waste and toxins, but also sweating, smooth blood and Qi, excitement of the vagus nerve, involving the brain and even the overall functional activities of life, can repair the malfunctioning neurohumoral regulation, can change the pathological state of the internal environment, to achieve the “evil to the right since the restoration” of the therapeutic effect. Vomiting can cure diseases, which is one of the valuable experience accumulated by working people from long-term medical practice. The Yellow Emperor’s Classic of Internal Medicine has records on vomiting, such as Suwen? Yin and Yang Ying Xiang Daxue” said: “its high, and thus over the” (Zhang Jinyue commentary: over, also, said to rise and spread, vomit Chung’s); “Shennong Ben Cao Jing” has been recorded in the vomiting medicine. Such as guati, li lu and other drugs. Han Dynasty Zhang Zhongjing understanding of vomiting method has developed, the application of the vomiting method is very strict, pointing out what should be vomited, what can not be vomited, for those who do not vomit, proposed “less added to the fast vomit for the degree”, and vomiting method prescriptions a thing Guati San treatment “sun in the drink, body heat pain heavy “and” persistent food in the epigastrium. Qing dynasty Cheng Guopeng “medical heart enlightenment” to “vomiting” listed in the “eight methods of medicine”, specifically as a treatment method introduced separately. Both pointed out that “when vomiting can not vomit and can not not vomit, vomiting can not be its method to mistake people”, but also from the perspective of methodology to teach people how to “can not vomit” evidence into “can vomit” evidence. The modern late famous doctor Pu Fu Zhou in the book “Pu Fu Zhou medical experience” put forward the principle of “vomit but do not slow down”. That is, to seize the disease, the urgent attack do not lose, in order to obtain the cure. In short, “vomiting” from the “Yellow Emperor’s Classic of Internal Medicine” since the development of successive generations of doctors, especially Zhang Zihe’s contribution in this area is particularly outstanding. Unfortunately, in modern times, due to changes in the practice environment and medical education, there are fewer and fewer doctors who are skilled in the vomiting method of healing.
