此谓阴阳二气偏虚，则受于毒。若病身重腰脊痛，烦闷，面赤斑出，咽喉痛，或下利狂
走，此为阳毒。若身重背强，短气呕逆，唇青面黑，四肢逆冷，为阴毒。或得病数日，变成
毒者；或初得病，便有毒者，皆宜根据证急治。失候则杀人。
夫时气病，湿毒瓦斯盛，蓄于脾胃，脾胃有热，则新谷郁蒸，不能消化，大小便结涩，故
令身面变黄，或如橘柚，或如桃枝色。
病后邪气未散，阴阳尚虚，因为劳事，致二气交争，阴胜则发寒，阳胜则发热，故令寒
热往来，有时休作而成疟。
此谓病后余毒未尽，形证变转，久而不瘥，阴阳无复纲纪，名为败病。
夫病新瘥者，血气尚虚，津液未复，因即劳动，更成病焉。若言语思虑则劳于神，梳头
澡洗则劳于力，未堪劳而强劳之，则生热，热气还经络，复为病者，名曰劳复。
夫病新瘥者，脾胃尚虚，谷气未复，若即食肥肉、鱼 、饼饵、枣、栗之属，则未
能消化，停积在于肠胃，使胀满结实，因更发热，复为病者，名曰食复也。
夫病新瘥者，阴阳二气未和，早合房室，则令人阴肿入腹，腹内 痛，名为交接劳复。
阴阳易病者，是男子、妇人时气病新瘥未平复，而与之交接得病者，名阴阳易也。其男
子病新瘥未平复，而妇人与之交接得病者，名曰阳易。其妇人得病新瘥未平复，而男子与之
交接得病者，名曰阴易。若二男二女，并不相易。所以呼为易者，阴阳相感动，其毒度着于
人，如换易也。其病之状，身体热冲胸，头重不能举，眼中生眵，四肢拘急，小腹 痛，手
足拳，皆即死。其亦有不即死者，病苦小腹里急，热气上冲胸，头重不欲举，百节解离，经
脉缓弱，气血虚，骨髓竭，便恍恍吸吸，气力转少，着床不能摇动，起居仰人，或
引岁月方死。
这是因为发汗之后津液亏虚减少，患者小肠内有潜伏的热邪，所以导致小便不通。
这指的是阴阳二气偏于虚弱，从而受到毒邪侵袭。如果病症表现为身体沉重、腰脊疼痛、烦闷、面部发红出现斑疹、咽喉疼痛，或者腹泻、狂躁奔走，这称为阳毒。如果病症表现为身体沉重、背部僵硬、呼吸短促、呕吐逆气、嘴唇发青、面色发黑、四肢厥冷，这称为阴毒。无论是患病数日后转变为毒证，还是初起即带有毒证，都应当根据证候紧急治疗。延误时机则会致死。
时气病中，湿毒之气旺盛，蓄积在脾胃，脾胃有热，则新摄入的谷物郁结蒸腾，无法消化，导致大小便结滞涩痛，因此使身体和面目变黄，颜色或像橘子皮，或像桃树枝的颜色。
疾病痊愈后邪气尚未消散，阴阳仍然虚弱，因为从事劳作，导致阴阳二气相互争斗，阴胜则发作寒战，阳胜则发作发热，因此导致寒热往来，有时停止有时发作，从而形成疟疾。
这指的是病后余毒未尽，形体症状发生转变，日久不愈，阴阳失去纲纪调节，称为败病。
凡是疾病刚刚痊愈的人，血气依然虚弱，津液尚未恢复，如果立即进行劳动，会再次致病。如果言语思虑，则是神志劳损；如果梳头洗澡，则是体力劳损。如果不能承受劳作而强行劳作，就会产生热邪，热气回流至经络，再次引发疾病，称为劳复。
凡是疾病刚刚痊愈的人，脾胃依然虚弱，谷气尚未恢复，如果立即食用肥肉、鱼类、糕点、枣、栗子之类的食物，则难以消化，停滞积聚在肠胃，导致胀满结实，进而再次发热，重新致病，称为食复。
凡是疾病刚刚痊愈的人，阴阳二气尚未调和，过早行房事，会导致男子阴囊肿大并牵引入腹，腹内疼痛，称为交接劳复。
阴阳易病，是指男子或妇人患时气病刚刚痊愈尚未平复，就与他人发生性关系而得病，称为阴阳易。如果是男子病刚痊愈尚未平复，与女子发生性关系而得病的，称为阳易。如果是女子得病刚痊愈尚未平复，与男子发生性关系而得病的，称为阴易。如果是两个男子或两个女子之间，并不互相传染。之所以称为“易”，是因为阴阳相互感应，毒邪转移附着于人，如同更换一样。这种病的症状是：热气冲撞胸部，头部沉重不能抬起，眼中分泌物增多，四肢拘挛紧急，小腹疼痛，手足蜷缩成拳，这些情况都会立即死亡。也有不立即死亡的，病人痛苦于小腹内部急迫，热气上冲胸部，头部沉重不想抬起，全身关节松散无力，经脉缓弱，气血虚弱，骨髓枯竭，神情恍惚，气息微弱，气力逐渐减少，卧床不能摇动，起居需要依靠他人，有的拖延岁月才死亡。
This is due to the deficiency and scarcity of body fluids after sweating, combined with latent heat in the Small Intestine (Small Intestine), resulting in the obstruction of urination.
This refers to a condition where both Yin and Qi are biased towards deficiency, making one susceptible to toxic pathogens. If the symptoms include heavy body, pain in the waist and spine, restlessness, red face with macules, sore throat, or diarrhea with mania and running about, this is termed Yang Toxin (Yang Du). If the symptoms include heavy body, stiff back, shortness of breath, vomiting and regurgitation, cyanotic lips, blackish complexion, and cold limbs, this is termed Yin Toxin (Yin Du). Whether the toxin develops after several days of illness or is present from the onset, urgent treatment according to the syndrome is required. Delaying treatment will lead to death.
In seasonal febrile diseases (Shi Qi Bing), damp-toxic qi is abundant and accumulates in the Spleen and Stomach. Heat in the Spleen and Stomach causes newly ingested food to stagnate and steam, preventing digestion. This leads to constipation and difficult urination, causing the body and face to turn yellow, resembling the color of an orange peel or peach branch.
After the illness, pathogenic factors have not dissipated, and Yin and Yang remain deficient. Engaging in labor causes these two Qi to contend; if Yin prevails, chills occur; if Yang prevails, fever occurs. This results in alternating chills and fever, occurring intermittently, forming Malaria (Nüe).
This refers to residual toxins remaining after illness, with changes in physical manifestations that persist without recovery for a long time, leading to a loss of regulatory order between Yin and Yang, named Debilitating Disease (Bai Bing).
For those whose illness has just resolved, Blood and Qi are still deficient, and body fluids have not yet recovered. Immediate labor will cause recurrence. Mental exertion such as speaking or thinking damages the Spirit (Shen); physical exertion such as combing hair or bathing damages strength. Forcing labor beyond capacity generates heat, which returns to the meridians, causing disease again, known as Labor Recurrence (Lao Fu).
For those whose illness has just resolved, the Spleen and Stomach are still weak, and Gu Qi (Grain Qi) has not recovered. Consuming fatty meats, fish, pastries, dates, chestnuts, etc., immediately leads to indigestion, accumulation in the intestines and stomach, causing distension and hardness, followed by recurrent fever and illness, known as Food Recurrence (Shi Fu).
For those whose illness has just resolved, Yin and Yang Qi are not yet harmonized. Early sexual intercourse causes swelling of the genitals extending into the abdomen and abdominal pain, known as Intercourse-induced Labor Recurrence (Jiao Jie Lao Fu).
Yin-Yang Exchange Disease (Yin Yang Yi Bing) occurs when a man or woman who has recently recovered from a seasonal febrile disease but has not fully stabilized engages in sexual intercourse with another person, transmitting the disease. If a man recovers and transmits it to a woman through intercourse, it is called Yang Exchange (Yang Yi). If a woman recovers and transmits it to a man through intercourse, it is called Yin Exchange (Yin Yi). No exchange occurs between two men or two women. It is called "Exchange" because Yin and Yang mutually influence each other, and the toxin transfers to the other person, like a substitution. The symptoms include heat rushing to the chest, heaviness of the head making it difficult to lift, eye discharge, spasm and stiffness of the four limbs, lower abdominal pain, and clenched fists and toes, which can lead to immediate death. In cases where death does not occur immediately, the patient suffers from urgency in the lower abdomen, heat rushing to the chest, heaviness of the head, sensation of joints separating, slack and weak meridians, deficiency of Qi and Blood, exhaustion of Marrow, mental confusion, faint breathing, decreasing strength, inability to move while lying down, dependence on others for daily activities, and may die after months or years.
