In ancient times, traditional Chinese medicine practitioners recognized plum kernel qi, mostly from the throat intermediary between the feeling, hot skin, such as broken flocculent, such as membrane, such as plum kernel and other foreign body sensation in the throat to describe its symptoms, according to the combination of Chinese and Western medicine, plum kernel qi should be equivalent to Western medicine pharyngeal foreign body sensation. The causes of pharyngeal foreign body sensation are more complex. From the perspective of Western medicine, the pharyngeal plexus consists of the pharyngeal branch of the glossopharyngeal nerve and vagus nerve, as well as the pharyngeal branch of the sympathetic nerve from the superior cervical ganglion. In clinical practice, foreign body sensation in the pharynx is particularly common due to gastric lesions (such as chronic gastritis and gastric ulcer). The understanding of the pathogenesis of plum kernel gas in Chinese medicine and its evidence and treatment typing methods are generally as follows. First, according to the understanding of the evidence and treatment of the disease mechanism of the internal organs. Mainly due to the heart, liver and gallbladder, spleen and stomach and other internal organs disorders, treatment in the regulation of the internal organs. The heart is the main blood vessel and the spirit, if the heart and blood is insufficient, the spirit is not nourished, it is suspicious and good at thinking, feeling in the throat like something like cancer, restlessness, especially in middle-aged women, available Ganmai Dazao Tang and Gui Spleen Tang and other additions and reductions. The liver and gallbladder are responsible for drainage, while the spleen and stomach are responsible for transportation and transformation, and are the hubs of qi elevation. If the liver is depressed, the bile is not drained, the Shaoyang meridian is blocked, the qi is unfavorable, mainly discomfort on one side of the throat, or see chest tightness, not wanting to eat, heartburn, easy dry retching, bitter mouth, dry throat, pulse string, available Xiao Chai Hu Tang main. If the liver depression offends the spleen, the transport and transformation is not healthy, the stomach does not harmonize and descend, phlegm and turbidity is generated within, and the gas is knotted together, blocking the throat, then the pharynx, such as things, swallowing, vomiting, mainly liver depression offends the spleen, free remote san, four reverse san, such as the addition and reduction of regulation. For those with spleen deficiency and stomach failure, we can use Xuanfu Dianchu Shi Tang plus or minus to regulate it, and for those with cold in the liver and stomach, we can add dry ginger and Wu Zhuyu. If liver stagnation and fire injure yin, we can use consistent decoction or Danjuana Free and Easy San to add and reduce, if accompanied by lung yin deficiency, add yin nourishing and lung clearing products as appropriate. Second, according to the qi, blood and fluid pathogenic evidence and treatment understanding. Mainly due to “depression”, it is classified as depression. For those who are mainly suffering from qi stagnation and phlegm coagulation, the symptoms are intermittent and may be aggravated by emotional discomfort, obstruction in the pharynx without localization, or stuffiness and pain in the chest, which can be treated by adding and subtracting Han Xia Hou Pu Tang or Si Wei San. In cases with phlegm coagulation, the obstruction in the pharynx is persistent, sometimes light and sometimes heavy, with false irritation and sleeplessness, palpitations, chest tightness, bitterness in the mouth, good breath, or cough with phlegm, dizziness and vomiting, yellowish coating on the tongue and slippery pulse. Treatment is to resolve phlegm, harmonize the stomach and clear heat to drain bile, and can be added and subtracted with warm bile soup. Blood stasis is a variable disease, mostly of long duration, due to qi stagnation or phlegm condensation. There are also dampness and turbidity of the evil stay together, resulting in qi stagnation, obstructing the pharynx, resulting in the birth of plum kernel gas. The symptoms are pharyngeal stagnation, head and body heaviness, chest tightness and abdominal distension, mucousy stools, or hot odor, yellow and greasy tongue coating, and slippery pulse. Treatment is to resolve dampness and clear heat, detoxify the pharynx. Ganlu Disinfectant Dan is used for this purpose. To sum up, the treatment of pharyngeal syndrome should be balanced with the treatment of phlegm, dampness and stasis. At the same time, attention should be paid to weighing both the symptoms and the root cause, and reasonable prescription of drugs, and emphasize psychotherapy, including careful inquiry and examination, so that patients have a sense of trust, while patient and kind explanation, persuasion, so that patients eliminate doubts, so as to achieve better results.
