阳毒这种病，身体沉重，腰背部疼痛，心中烦闷不安，胡言乱语，或者四处奔走，或者看见鬼怪，或者吐血、下痢，脉象浮大且数，面色红赤，斑纹像锦缎一样，咽喉疼痛，吐出脓血，发病五天内可以治疗，到了第七天就无法治疗了。有的伤寒病在一两天内就变成阳毒。或者服药后，经过催吐、泻下之后变成阳毒，用升麻汤主治。
阴毒这种病，身体沉重，背部僵硬，腹中绞痛，咽喉不畅利，毒气攻心，心下部坚硬，呼吸短促不能顺畅呼吸，呕吐逆气，嘴唇发青，面色发黑，四肢冰冷，脉象沉细紧数，身体感觉像被殴打过一样，发病五到六天可以治疗，到了第七天就无法治疗了。有的伤寒初病一两天，就结成阴毒。或者服药六七天以上直到十天，变成阴毒，用甘草汤主治。
百合病的症状，常常沉默想睡觉，但又不能躺卧；有时像健康人一样，想要出门行走，却又不能行走；心里想吃东西，却又吃不下；有时候觉得食物美味，有时候又讨厌闻到食物的气味；好像冷却不冷，好像热却不热；早晨起来口苦，小便颜色深黄，身体外形看起来正常，脉象微数。百脉同出一源，却都生病了，应当根据具体证候进行治疗。百合病，表现为阴证特征的，用阳法来救治；表现为阳证特征的，用阴法来救治。如果见到阳证却去攻伐阴分，又再发其汗，这是逆治，病难治愈；见到阴证却去攻伐阳分，又再用下法，这也是逆治，病难治愈。（《千金方》说：病症表现在阴而攻伐其阳，则阴邪不能解除，再发汗就是逆治。病症表现在阳而攻伐其阴，则阳邪不能解除，再用下法，病就不会痊愈。）
狐惑病，其气色表现像伤寒，沉默想睡觉，眼睛闭不上，睡卧起立都不安宁。腐蚀在喉部叫“惑”，腐蚀在阴部叫“狐”。狐惑病，都不想吃东西，闻到食物气味就恶心，面目颜色一会儿红、一会儿白、一会儿黑。毒气腐蚀在上部的，声音嘶哑；毒气腐蚀在下部的，咽喉干燥。腐蚀在上部，用泻心汤主治。腐蚀在下部，用苦参汤煎水熏洗；腐蚀在肛门的，用雄黄烟熏。病人脉数，没有发热，轻微烦躁，沉默想睡觉，出汗，刚得病三四天，眼睛发红像斑鸠的眼睛；得病七八天，眼四角变黄黑，如果能吃东西的，说明脓已经形成，用赤小豆当归散主治。病人有的从呼吸道开始，向上腐蚀咽喉；有的从下焦开始，向下腐蚀肛门和外阴。腐蚀上部叫惑，腐蚀下部叫狐。狐惑病，用猪苓散主治。
Yang poison disease presents with heavy body, pain in the waist and back, mental restlessness, delirious speech, or running about, or seeing ghosts, or hematemesis and dysentery. The pulse is floating, large, and rapid. The face is red with mottled spots like brocade patterns, accompanied by sore throat and expectoration of pus and blood. It is treatable within five days; after seven days, it becomes untreatable. Some cases of cold damage transform into yang poison within one or two days. Alternatively, after taking medicine that induces vomiting or purgation, the condition may transform into yang poison, which is primarily treated with Shengma Tang (Cimicifugae Decoction).
Yin poison disease presents with heavy body, stiff back, colicky abdominal pain, difficulty in the throat, toxic qi attacking the heart, hardness below the heart, shortness of breath with inability to breathe deeply, vomiting and regurgitation, cyanotic lips, blackish complexion, and cold extremities. The pulse is deep, fine, tight, and rapid. The body feels as if beaten. It is treatable within five to six days; after seven days, it becomes untreatable. Some cases of initial cold damage form yin poison within one or two days. Alternatively, after taking medicine for six to seven days up to ten days, the condition may transform into yin poison, which is primarily treated with Gancao Tang (Licorice Decoction).
The manifestation of Baihe Bing (Lily Disease) is characterized by a desire to remain silent and lie down, yet an inability to do so; sometimes resembling a healthy person who wishes to walk but cannot; desiring food but unable to eat; at times finding food palatable, at other times repulsed by the smell of food; appearing neither cold nor hot; bitter taste in the mouth upon waking, dark yellow urine, while the physical appearance seems normal. The pulse is slightly rapid. Since all vessels originate from one source, they are all diseased; treatment should follow the specific syndrome. When Baihe Bing manifests with yin characteristics, it should be rescued by yang methods; when manifesting with yang characteristics, it should be rescued by yin methods. If yang manifestations are present but yin is attacked, followed by sweating, this is contrary to principle, and the disease is difficult to treat. If yin manifestations are present but yang is attacked, followed by purgation, this is also contrary to principle, and the disease is difficult to treat. (*Qianjin Fang* states: If the disease is in yin but yang is attacked, yin cannot be resolved, and inducing sweat is contrary to principle. If the disease is in yang but yin is attacked, yang cannot be resolved, and purgation will not cure the disease.)
Huhuo Bing (Fox-Spook Disease) presents with symptoms similar to cold damage: silence, desire to sleep, inability to close the eyes, and restlessness in lying down and rising. Erosion in the throat is called "huo" (spook); erosion in the genitalia is called "hu" (fox). Patients with huhuo Bing have no appetite and are repulsed by the smell of food. The facial color changes alternately between red, white, and black. Toxic erosion in the upper part causes hoarseness; toxic erosion in the lower part causes dry throat. Erosion in the upper part is primarily treated with Xixin Tang (Pinellia and Gentian Decoction). Erosion in the lower part is washed with Kushen Tang (Sophora Root Decoction); erosion in the anus is fumigated with Xionghuang (Realgar). The patient has a rapid pulse, no fever, slight irritability, silence, desire to sleep, and sweating. Within three to four days of onset, the eyes become red like those of a turtledove; after seven to eight days, the corners of the eyes turn yellow-black. If the patient can eat, pus has formed, and Chixiaodou Danggui San (Adzuki Bean and Angelica Sinensis Powder) is primarily used. The disease may start from respiration, eroding upward into the pharynx, or from the lower jiao, eroding downward into the anus and genitals. Erosion in the upper part is huo; erosion in the lower part is hu. Huhuo Bing is primarily treated with Zhuling San (Polyporus Powder).
