Yu Genchu pointed out in the Common Theory of Typhoid Fever: “Where the treatment of typhoid fever to open up the depression as the first”. It suggests that the six channels of typhoid fever have depression as the commonality of the disease mechanism. One, all six channels have depression evidence six channels to transport qi and blood, unrestricted yang qi, it is appropriate to circulate and evil suppression. The smoothness of the vitality is flourishing, suppressing the disease. The sun unifies the Ying and Wei, its gas is distributed on the table, Ying and Wei is about the spirit, so the sun Qi and Qi, Ying and Wei is out of harmony, outside the meridian is unfavorable, for headache, chills and fever, for the spirit is not invigorated. Yangming is full of qi and blood, “the stomach and intestines flow, qi is smooth” (Ben Jing Shu Zhi), Yangming qi is stagnant, qi and blood is not smooth; earth congestion and wood depression, liver loss of drainage, for the fullness of the abdomen, belching less food, emotional distress, stool is not smooth. Shaoyang is the master of the pivot, Yang Qi is popular and smooth, out of the table and into the interior, all rely on Shaoyang for its mediation, the pivot is not conducive, then the chest is bitter and full, hey do not want to eat, the heart is annoyed and vomiting, the bowels are not smooth. Taiyin in Tibet for the spleen and lungs, the spleen is the main ascending and clearing, and the stomach is the same as the pivot of qi lift: the lungs are the main body of qi, “all the qi large-air stalls allow charm inonweigh thin F (9) poor grits stop stool ะจ stop ring strips of ancient yttrium miscellaneous ancient fun funk redress vomit (8) 8 bow around (2) 7 crack bath (3) hazel depression. Shao Yin is the main water and fire, in the upper for the heart, the main fire to hide the spirit, in the lower for the kidney, the main water to hide the essence. Shao Yin Yang Qi is not enough, the spirit is not invigorated, and even “but want to sleep”, “the heart is troubled but want to sleep”, “but want to sleep”; Shao Yin water deficit fire, water deficit loss of nourishment, fire disturbs the gods. “disturbed in the heart and unable to sleep”. The blood is the mainstay of the syncope, and the liver is the mainstay of the drainage, and the liver vein is “injected into the chest”; the pericardium of the hand syncope is “the official of the minister, happy and happy out of the place”, performing orders on behalf of the ruler, and “the blood is the god of man”. Blood is the spirit of man. The six channels of yin and yang are the basis for the onset of depression. The six channels of depression are closely related to the strength and weakness of the six channels of yin and yang. In general, the main point is that the Yang Qi is in full bloom, the disease is born in the three Yang, and easy to turn into heat and fire, long will hurt the Yin and consume Qi, the actual evidence is mostly, or mixed with the real; Yang Qi is not enough, the disease in the three Yin, belong to the deficiency evidence. Yang deficiency is prone to internal cold, while fluid and blood are prone to stop and stasis, forming a mixed pattern of deficiency and reality. If the yin is insufficient, it is easily affected by changes in emotion and will, and the disease mostly occurs in the three yin, and the most evil is found in the liver meridian of the fructus yin. The basic rule of treatment for depression is to dredge the qi mechanism from the six meridians. The main cause of solar depression is the loss of harmony between the Ying and Wei, so it is advisable to harmonize the Ying and Wei and smooth the solar meridians. The main feature is discomfort with headache, neck discomfort, or body aches and pains, and no obvious abnormality in diet and stool. Gui Zhi Tang is the representative formula. For neck discomfort, use Gui Zhi plus Ge Gen Tang; for insomnia and palpitations, use Gui Zhi plus Dragon Bone and Oyster Tang; for prolonged illness and deficiency of Ying and Wei, with body aches and pains, aggravated by exertion but alleviated by rest, with a pale tongue and weak pulse, use Gui Zhi Xin Jia Tang combined with Huang Qi Gui Zhi Wu Wu Wu Wu Tang.

Yangming depression is mainly due to the loss of harmony of the gastrointestinal qi. The treatment should be to harmonize the gastrointestinal qi and lower the turbidity and channel the stagnation. If the stomach Qi is not harmonized, the emotions are not smooth, the stomach and epigastric distention and fullness, belching and cacophony, reduced diet, unpleasant stools, and greasy tongue coating, use orange and hedgehog and ginger soup combined with three things of white powder to remove croton cream, add half asia and whirling dried flowers; if the stomach is not harmonized and lowered, food stagnation does not dissolve, belching and food odor, thick and greasy tongue coating and slippery pulse, use half asia and thick park soup with jiao sanxian and betel nut; if the stomach Qi is stagnant, food stagnation turns into heat, damp-heat stagnation, stomach and epigastric distention and fullness or pain, yellow and greasy tongue coating, slippery or smooth pulse, use half asia diarrhea and heart soup combined with gardenia, and damp-heat stagnation. The use of Hanxia diarrhea heart soup combined with gardenia seeds and thick park soup, bowel irregularities, combined with Xiao Cheng Qi Tang. Yangming Shaoyang Qi stagnation, with Da Chai Hu Tang, Yangming damp-heat congestion, earth congestion and wood depression, impatience and irritability, bitter and dry mouth, irregular stool, yellowish tongue coating, with Artemisia Inchi Tang and Xiao Shen Che Tang. Shaoyang depression is mainly due to unfavorable pivot mechanism and irregular flow of Yang Qi. For symptoms of chest pain and fullness, inappetence to eat and drink, heart trouble and bitterness, red tongue and thin pulse, use Xiao Chai Hu Tang with Chuan Bai Mu and Sheng Ma Ye; for symptoms of nausea and vomiting, irregular stools with yellowish coating, use Da Chai Hu Tang; for symptoms of bitterness and thirst with inappetence to drink and loose stools, use Chai Hu Gui Zhi Gan Jiang Tang.

For deficiency of lung yin, chest tightness, abnormal sleep, and tasteless diet, use Mai Men Dong Tang and Bai He Zhi Mu Tang with Chuan Bei Mu and Radix Platycodon. Taiyin spleen is responsible for water and fluid transportation, and lung is responsible for regulating water channels. Taiyin qi is stagnant, water and fluid transportation and distribution are abnormal, resulting in internal growth of phlegm and dampness. Shaoyin depression is blamed on the deficiency of water and fire, and the treatment is divided into two ways: strengthening the main body of water and benefiting the source of fire. Shao Yin Yang Qi deficiency, depression, fatigue, sleeplessness, seemingly awake, lazy speech and lazy movement, light and fat tongue, sunken and weak pulse, use Si Wei Tang instead of Gunpowder; if there is pain in the limbs, or headache and body pain, heavy limbs, light tongue, use Pei Zi Tang; if there is easy fright and fear, insomnia and dreaminess, light tongue, sunken and thin pulse, use Er Jia Long Mu Tang.

Heart Qi deficiency, confusion, grief and anxiety, mental confusion, sadness and weeping, weakness and tiredness, pale tongue, weak pulse, Ganmai Dazao Tang with Baihe Dihuang Tang, which nourishes the heart and calms the mind by benefiting Qi and tonifying the middle. The syncretic yin depression is blamed on the liver meridian with unfavorable qi flow, or the heart pericardium with stagnation and loss of harmony. Liver Qi stagnation, depression, sullenness, distension and fullness in the chest, belching and sighing, the evidence changes with mood fluctuations, with a light red tongue, thin white fur and string pulse. The treatment is to dredge the liver and regulate the qi, and to smooth the qi flow, using Si Yan San combined with Han Xia Hou Pu Tang as the main formula, and adding or subtracting with the evidence; or using Decoction of Liver, which has a stronger effect on qi and relieves depression, for the treatment of “violent anger injuring the liver, qi rebellion, fullness and obstruction, etc.”. If liver stagnation turns into heat and fire, combining with gardenia and black bean soup, or white head worm soup, to clear liver heat, promote depression and dredge the liver; if fire is strong and hurts yin, using peony and roasted licorice, adding angelica; if liver and kidney yin is deficient, qi is not smooth, and emotions are unhappy, using Liu Wei Di Huang Wan and sour date soup, adding Chai Hu and Chuan Bei Mu.
