时气之病，是四时之间，忽有非节之气伤人，其病状似伤寒，亦头痛壮热也。而腹满者
，是热入腹，与脏气相搏，气痞涩在内，故令腹满。若毒而满者，毒瓦斯乘心，烦懊者死。
时气之病，是四时之间，忽有非节之气伤人，其病状似伤寒，亦头痛壮热。热入腹内，
与腑脏之气相结，谓之结热。热则大小肠痞涩，大小便难而苦烦热是也。
时气之病，是四时之间，忽有非节之气伤人，其病状似伤寒，亦头痛壮热。若施治早晚
失时，投药不与病相会，致令病连滞不已，乍瘥乍剧，或寒或热，败坏之证，无常是也。
时气之病，是四时之间，忽有非节之气伤人，其病状似伤寒，亦头痛壮热。而又兼疟者
，是日数未满，本常壮热，而邪不退，或乘于阴，或乘于阳。其乘于阳，阳争则热；其乘于
阴，阴争则寒。阴阳之气为邪所并，互相乘加，故发寒热成疟也。
时气之病，是四时之间，忽有非节之气伤人，其病似伤寒，亦头痛壮热。而得吐下之后
，壮热犹不歇者，是肠胃宿虚，而又吐利，则为重虚，其热乘虚而入里，则表里俱热，停滞
不歇，故虽吐下而犹热也。
时气之病，是四时之间，忽有非节之气伤人，客于肌肤，与血气相搏，故头痛壮热。热
歇之后，不嗜食而面青者，是胃内余热未尽，气满，故不嗜食也。诸阳之气，俱上荣于面，
阳虚未复，本带风邪，风邪挟冷，冷搏于血气，故令面青也。
The disease of "Shi Qi" (Seasonal Epidemic Pathogen) refers to an illness caused by the sudden invasion of non-seasonal pathogenic factors during the four seasons. Its clinical manifestations resemble Shang Han (Cold Damage), also presenting with headache and high fever.
If abdominal distension occurs, it is because heat pathogens have entered the abdomen and clashed with the Qi of the Zang-Fu organs, causing Qi stagnation and obstruction internally, thus leading to abdominal fullness. If the toxicity is severe accompanied by distension, it indicates that toxic vapors have attacked the Heart; if the patient experiences mental restlessness and oppression (Fan Ao), it is a fatal condition.
The disease of "Shi Qi" refers to an illness caused by the sudden invasion of non-seasonal pathogenic factors during the four seasons. Its clinical manifestations resemble Shang Han, also presenting with headache and high fever. When heat enters the abdomen and knots with the Qi of the Fu and Zang organs, it is called "Jie Re" (Knotted Heat). Heat causes obstruction in the Large Intestine and Small Intestine, manifesting as difficulty in urination and defecation, along with severe烦热 (restless heat).
The disease of "Shi Qi" refers to an illness caused by the sudden invasion of non-seasonal pathogenic factors during the four seasons. Its clinical manifestations resemble Shang Han, also presenting with headache and high fever. If treatment is administered too early or too late, and the medication fails to counteract the pathogen, the disease becomes lingering and unceasing. It may fluctuate between remission and exacerbation, alternating between cold and heat. Such deteriorated syndromes are unpredictable and variable.
The disease of "Shi Qi" refers to an illness caused by the sudden invasion of non-seasonal pathogenic factors during the four seasons. Its clinical manifestations resemble Shang Han, also presenting with headache and high fever. If accompanied by Malaria symptoms, it is because the number of days has not yet reached completion, the original high fever persists without receding, and the pathogen remains. The pathogen may attack the Yin or the Yang. When attacking Yang, Yang struggles resulting in heat; when attacking Yin, Yin struggles resulting in cold. The Qi of Yin and Yang is overwhelmed by the pathogen and mutually invades each other, thus causing alternating chills and fever, forming Malaria.
The disease of "Shi Qi" refers to an illness caused by the sudden invasion of non-seasonal pathogenic factors during the four seasons, lodging in the skin and muscles and clashing with Blood and Qi, thus causing headache and high fever. After the high fever subsides, if there is loss of appetite and a bluish complexion, it is because residual heat in the Stomach has not yet cleared, and Qi is full/stagnant, hence the lack of desire to eat. All Yang Qi ascends to nourish the face. Since Yang Qi is deficient and has not recovered, and originally carries Wind pathogen, the Wind pathogen carries Cold. Cold clashes with Blood and Qi, thus causing the face to appear blue.
