Asthma is a disease characterized by episodes of phlegm and shortness of breath. Its attacks are often related to factors such as uneven hot and cold climate, improper diet, fatigue and stimulation of odor. In winter, the climate is easy to change, especially the cold, cold air stimulation easily triggers asthma, not only brings unimaginable pain to the patient, but more importantly, the long “asthma” does not heal can also bring serious complications, such as emphysema. Chinese medicine believes that asthma has a persistent root and is triggered by cold or exertion. Asthma can be triggered by cold in two ways: one is due to external wind and cold and internal stoppage of accumulated drinks. The symptoms include cough and wheezing, phlegm in the throat, thin white phlegm, no thirst, fear of cold without sweating, headache, cold limbs, white fur, floating string or slippery pulse. The treatment is Xiao Qing Long Tang with addition and subtraction as the main formula. The second is cold encapsulating heat, phlegm-heat within and wind-cold outside. The symptoms are coughing and wheezing, coughing with yellowish white phlegm, cold and fear of wind, spontaneous sweating, red tongue, thin yellow fur, and slippery pulse. The treatment is to add and subtract mala-xing-shi-gan-tang and Ding-tiang-tang. If triggered by climate or environmental changes, the patient feels itchy in the nose, throat, eyes and ears, sneezing, nasal congestion, runny nose, chest congestion, followed by a rapid onset of asthma with phlegm sounding in the throat and foamy phlegm, which is called wind-phlegm croup, the treatment is Su Xing Er Chen Tang and San Zi Yang Yin Tang with addition and subtraction. If the asthma occurs for a long time, with phlegm and gas stagnation and deficiency of both lungs and kidneys, it is called deficiency asthma. The symptoms include roaring in the throat like snoring, low voice, shortness of breath, shortness of breath, wheezing when moving, frequent attacks, weak coughing of phlegm, thin sputum or sticky and foamy sputum, and the treatment is to add and subtract Pingshang Gu Ben Tang. If asthma does not occur during the day, but occurs at midnight, it is called “nocturnal asthma”, which is considered by Chinese medicine to be due to yang deficiency at night, and yang energy is difficult to reach outside. Asthma is treated at the onset of symptoms and at the beginning of the day. Treating the symptoms is to relieve the attack, while treating the root is to prevent recurrence, which is also the key to treatment. The main organs of the lungs, spleen and kidneys and their interactions should be taken into account. Generally speaking, deficiency of lung qi is manifested by coldness, spontaneous sweating, easy to catch cold, frequent sneezing before attack, itchy and teary eyes, so it is advisable to nourish lung qi and strengthen yang, such as Yu Ping Feng San, Huang Qi Jian Zhong Tang, Sheng Wei San, etc. Spleen deficiency is manifested by poor digestion, phlegm after eating, loose stools or easy to have loose stools, so it is advisable to regulate the spleen and stomach and warm the middle yang, such as Six Gentlemen’s Soup, Tonic Zhong Yi Qi Soup, etc. If the patient has spermatorrhea, premature ejaculation, lumbar soreness and cold limbs, tinnitus, memory loss, palpitations and panting, it is appropriate to fill the essence and warm the lower yuan, and according to the yin deficiency and yang deficiency, use six flavors and eight flavors with Ziheche, tortoise and deer Erxian cream, Qing’e pill and so on. There was a patient surnamed Li, female, 22 years old. She had a history of asthma for 8 years, especially in autumn and winter. In the past 3 months, she had an attack every night with chest tightness and sneezing, sticky sputum, itchy throat, thin and slightly counted pulse, and red tongue. The disease is in the lung and spleen. Firstly, we used Xiao Qing Long Tang with Scutellaria baicalensis to decompose the surface and the interior, and secondly, Yu Ping Feng with Kidney Qi Pill with Daphne Scoparia, Aster, Winter Flower and Su Zi to nourish the lung and benefit the kidney and warm the lung meridian. After half a month, the asthma was greatly reduced. Later, the symptoms all disappeared after a month of regulating with raw pulse san and lung tonic soup plus saxifrage, winter flowers, aconite and almond, etc. Later, he was regulated from the medicine of tonifying the lung and warming the kidney to strengthen the spleen and resolve phlegm for more than 2 months, without any unprecedented occurrence. Another example is Zhang, male, 60 years old, asthma for more than 20 years, in recent years, regardless of winter and summer, monthly attacks. In addition to asthma, he also has phlegm, loose stools, decreased nausea, back pain, and little sleep, with white and greasy coating and sunken and soft pulse. This is due to deficiency of Yang in the spleen and kidney and phlegm in the lung. The treatment was to treat the symptoms by adding and subtracting Su Zi Qi Lowering Soup, Ling Gui Zhu Gan Soup, San Zi Yang Yin Soup, and Scape Drabble, Bai Qian, Gan Jiang and Wu Wei. After half a month, the asthma was significantly reduced and the sputum was also reduced. After a month of treatment with Jinshui Liujun and Renqi Wan, the asthma had subsided, and then a cream was boiled to consolidate it with ten whole tonic, pacifying asthma and fixing the root of the soup, and Renqi Wan with Ziheche, deer horn gum and gum. ”The lung is a delicate organ that does not tolerate cold and heat. For asthma patients, they should also pay attention to proper exercise, frequent sun exposure and avoid long periods of closed doors and windows in winter. The appropriate time for tonic, so that the lung can be nourished to reduce the occurrence of asthma, can often eat some beneficial food, such as lamb, dog meat, venison, donkey meat, prawns, chicken soup, as well as sesame, soy products, honey, radish, snow pear, water chestnut, duck pear, lotus seeds, yam, lotus root, walnuts and other nourishing Yin and dry, moisten the lungs to stop coughing food. And according to the needs of the disease, medicinal supplements can be made, such as the cream formula made of the principle of strengthening the spleen and warming the kidneys with the principle of removing phlegm, regulating the qi and dispelling the wind, which has both tonifying and therapeutic effects, used to treat asthma, can improve the body’s constitution, enhance the body’s ability to resist disease and reduce or prevent attacks.
