At the end of the Eastern Han Dynasty, there was a serious epidemic (influenza) outbreak in Changsha, and many people lost their lives. At that time, Zhang Zhongjing, as an outstanding doctor, personally participated in the fight against influenza. Through in-depth practice, he has accumulated rich clinical experience, and has made in-depth summaries and condensations. In the process, he put forward the famous theory of the dialectic of the six classics, and created a variety of effective prescriptions for influenza such as Guizhi Tang, Xiao Chai Hu Tang, Baihu Tang, and Chengqi Tang. These formulas still play an important role in the field of traditional Chinese medicine and have made indelible contributions to the cause of human health.
Climate variability is closely related to influenza epidemics. Traditional Chinese medicine theories have an in-depth understanding of the impact of climate change on disease. According to this theory, climate change can lead to four scenarios, namely: to but not to, not to, to but not to, and to too much. All four conditions can affect the spread and outbreak of the disease. Therefore, doctors need to pay close attention to climate change and take corresponding prevention and control measures according to the specific situation to ensure people's health and safety.
To but not to:The big green dragon soup is the most suitable
In Yuyao in the 70s of the 20th century, Lubu District and Zhangting District were hit by an outbreak of influenza. In that season, it was supposed to be the height of summer, but strangely enough, the weather was unusually cold, and in the morning it was even necessary to wear cotton clothes. Such an abnormal climate makes people extremely susceptible to wind cold. The flu spread rapidly in the region, with many families falling ill at the same time. Every day, there is a surge in the number of patients in the hospital, about 80% of whom are flu patients. The main symptoms of these patients with influenza are chills, fever, and anhidrosis, with a temperature of 38 to 38Between 5, headache, nasal congestion, runny nose, and joint aches all over the body. A small percentage of patients will have a slight cough and mild pharyngeal congestion. On examination, their white blood cell count and neutrophil count remained normal, but lymphocyte and eosinophil counts increased. As for the cause of the flu, experts believe that it is mainly due to the "to-to-come" climate impact. The season that should have been warm was unusually cold, and the patients felt the cold evil, and the evil qi invaded from the bladder of the foot sun, and was condensed between the sun and the sun. **This disease, if only the white tiger soup with cinnamon branches is used, it is biased towards Yangming; However, the use of cinnamon sticks alone is insufficient. Therefore, it is necessary to solve the evil of the sun and yang meridians at the same time, and it is most appropriate to choose Daqinglong soup. The cinnamon branches and ephedra in the Daqing Dragon Soup can jointly solve the evil of the sun, and the use of hemp and cinnamon together can increase the power of solving the surface. For the symptoms of thirst and drinking, this is a phenomenon that the heat in the sun is already burning, so it is necessary to reuse the plaster to clear the heat. At the same time, licorice, ginger, and jujube are added to reconcile the medicinal properties, so that hemp, cinnamon, gypsum and other medicines can better exert their medicinal effects, and jointly complete the task of solving the surface and clearing the inside. In practice**, about 10% of male patients develop epistaxis after taking the drug. Experts have different opinions on this phenomenon: some believe that it is a sign of deterioration of the condition; Some people also think that it is because the medicinal properties of Ma Gui are too strong and not suitable for patients. But in fact, the "Treatise on Typhoid Fever" clearly points out that epistaxis is a manifestation of evil fever and a sign of improvement. Usually epistaxis will stop on its own in about half a day, and hemostatic drugs should not be used at this time, because this may cause internal disturbance of evil qi. It was observed that the fever of the patient would follow a ladder downward trend the day after epistaxis. Although most patients are able to use Daqinglong Tang quickly**, there are still a few cases of fever and chills with a body temperature of 39 or higher. For these patients, the method of combining Xinliang Jieping with Qingli heat should be used instead, and Yinqiaosan and Baihu decoction should be selected. Through this, the heat can gradually subside and restore health. In addition, about 12% of patients will experience temporary chest tightness, irritability and other uncomfortable symptoms the day after taking Daqinglong soup. For these conditions, doctors advise patients to drink plenty of hot water to sweat and reduce fever quickly. As the sweating fever subsides, these uncomfortable symptoms will gradually subside. This is just as it is said in the "Book of Shang": "If the drug cannot cause a vertigo reaction, then the disease is difficult to **." 
Before it came:Ginseng is poisonous and dispersible
Ten days before the winter solstice in 1982, the temperature in the Yaodong region plummeted below freezing, an anomalous climate phenomenon known as "Arrived Before Arrival". At this time, sporadic cases of influenza began to appear in the area. Every day, the hospital sees about 10 such patients. Common symptoms include dizziness, weak legs, extreme fatigue, and chills. After measurement, the temperature of these patients was at 373 to 385. Their complexion is dull, their mouths are not thirsty, their tongues are pale coating, there are slight tooth marks on the edge of their tongues, and their pulses are characterized by a number of pulses. On a routine blood test, their white blood cells and neutrophils were about normal. Due to this "coming" cold weather, the body's yang energy is not fully stored, and it is difficult to resist the invasion of external evils. When the evil qi invades the solar meridian, the patient begins to experience a series of symptoms, such as dizziness, weak legs, and difficulty walking. At this time, it is urgent to adopt the method of upholding righteousness to drive away evil spirits. Yu Jiayan, a physician in the late Ming and early Qing dynasties, conducted an in-depth analysis of the pathogenesis of this disease in the "Medical Law", and proposed to use the method of "ginseng sequestration and poison powder". If the dose of astragalus is increased in clinical application, the effect will be more significant. Usually, after 3 doses, the patient's heat subsides and the symptoms of fatigue disappear. Even low white blood cell counts can be corrected in some patients. However, there are some cases that are more unique. The main symptoms in these patients are dizziness, fatigue, and pallor. After a routine blood test, their white blood cell count was as high as more than 20,000. For these patients who are obviously deficient, if they are given 2 doses of flavored ginseng, although the evil qi will temporarily subside, the patient's body temperature will not only rise, but also may appear red face, thirst and cold drinks and other symptoms of qi and burnt. At this time, it is necessary to switch to the warm disease method**, and good results can be obtained. These are just the special cases of individual cases. To and not to:Resistance to dissipation and dissolution of the surface of the clear
At the beginning of the 20th century, global temperatures continued to rise, and summer heat became almost the norm. After the summer solstice, the heat wave continues to hit, which is called "solstice but not go". At this time, the flu virus is also waiting for an opportunity to spread with the help of this heat wave. After influenza infection, people's symptoms are mostly chills and fever, and the body temperature fluctuates between 38 and 395. In the morning, the body temperature drops a little, but in the afternoon it rises again. Unbearable thirst, ruddy complexion, shortness of breath, constipation, pulses like strings or slippery numbers, and the tongue coating is thin white or yellow. Although routine blood tests may be normal, physical discomfort is hard to ignore. This influenza virus is the evil of anger described by Wu Youke in "Treatise on Warm Epidemics". It attacks people of all ages indiscriminately, young and old, who can be victims. When I was studying at New China Medical College in Shanghai, I had the privilege of studying with Mr. Zhang Cigong. He often uses Wu Youke's Dayuan drink to ** this disease, and the effect is remarkable. However, the condition seems to be much more serious today than it was then. The simple Dayuan drink can no longer meet the needs of **, and its anti-surface ability and laxative effect are insufficient. Therefore, we need to take a more comprehensive approach. Anti-Anger Powder is a compound preparation composed of a variety of traditional Chinese medicines such as Dayuan Drink and Lifting Powder. It has the effect of relieving the surface and clearing the inside, relieving the air and subduing the evil. Generally, after 3-5 doses, the patient's body temperature can return to normal. This is not only a direct blow to the virus, but also an effective regulation and recovery of the human immune system. By resisting dissipation, people are able to return to normal life and work more quickly.

It's too much:Fresh water reed root back to sigh
In the summer of 1940, the beginning of autumn had passed, but the scorching heat was still in full swing scorching the earth. There are still five short days left before the summer heat, but the weather is so hot that people sweat like rain, as if the summer heat does not want to go away easily. At this moment, an old man surnamed Chen walked into the outpatient department. He was in his sixties, his face was wrinkled, and his body trembled slightly. He told the doctor that he had been suffering from a high fever for three days, and every time he woke up, his body felt like he was being burned by flames, and sweat was sliding down his cheeks and wetting his clothes. His face was red, his breath was heavy, his mouth was dry, and he only wanted to drink a cold drink to relieve the heat that had risen from the bottom of his heart. His urine was dark red in color, like strong tea, indicating an extreme lack of water in his body. Doctors immediately examined him and found that his temperature was as high as 395. Significantly higher than normal body temperature. Through observation and diagnosis, the doctor believed that this was a case of damp temperature disease, which belonged to the type of Yangming heat. Therefore, the doctor decided to use White Tiger Soup for addition and subtraction**. This is a traditional Chinese medicine prescription, which is mainly used for symptoms such as high fever, thirst, and red urine. However, when he returned to the clinic the next day, the old man's high fever still did not subside, and his body temperature even climbed to 396℃。The doctor was puzzled, why did the white tiger decoction add or minus ** have no effect? He examined the old man's symptoms again, and suddenly noticed that the old man's tongue ** had a crack, and there was no trace of moist fluid to the touch. This discovery made the doctor suddenly realize that the high fever had seriously consumed the fluid in the body, resulting in the exhaustion of the chemical source. A simple spicy and cool heavy agent** can no longer meet the needs of the old man, and a large dose of traditional Chinese medicine must be added to nourish yin and nourish the liquid. Therefore, the doctor added fresh water reed root decoction juice instead of water to the original recipe, and at the same time added traditional Chinese medicine such as Xianshengdi, Xuanshen and Mai Dong. These traditional Chinese medicines have the effect of nourishing yin and nourishing the body, clearing away heat and moistening dryness, and can effectively replenish the fluid consumed in the body. On the third day, when the doctor took the temperature of the old man again, he was pleasantly surprised to find that his body temperature had dropped to 372. All symptoms have improved significantly. The old man's mental state has also recovered a lot, and he is full of emotion and sighs at the miraculous curative effect of traditional Chinese medicine. This case is clearly a case of "too much". In the environment of continuous high temperatures, the body's fluids are already consumed before the disease. Once the warm evil invades, the yin and jin in the body are obviously insufficient, and the simple pungent coolness can no longer meet the needs. In this case, it is necessary to combine pungent and cool with traditional Chinese medicine that nourishes yin and nourishes to achieve significant results. Mr. Fan Wenhu is a well-known Chinese medicine expert, and he likes to use fresh water reed root decoction instead of water to ** patients with high fever and injury. This method can quickly replenish fluid in the body and help the patient return to normal body temperature. In recent years, virus-induced infection and fever have become one of the key topics in contemporary medical research. Traditional Chinese medicine uses a variety of methods to improve diseases, such as supporting healthy qi, driving away evil spirits, stretching qi, warding off evil spirits, etc. If we can summarize a set of effective methods, we will definitely make greater contributions to human health. It is also a disease such as influenza, and its pathogenesis is also different due to climate changes and individual differences. As a result, the methods are also different. The characteristics of the methods of traditional Chinese medicine diseases vary from person to person, from time to time, and from place to place, and are still fully reflected in the rapid development of modern medicine today. This is one of the reasons why TCM still has a place in the field of modern medicine. Traditional Chinese medicine will continue to contribute to the cause of human health.
