【歌】劳热神思多困倦，客邪口燥及心烦，内伤有瘀成潮热，外感无时热又温，平昔经前实积看，去多经后
作虚论，实宜清解虚温补，寒热谵言另立门。
【论】王太仆曰∶如大寒而甚，热之不热，是无火也。热来复去，昼见夜伏，夜发昼止，是无火也，当治其
心。如大热而甚，寒之不寒，是无水也，当助其肾。心盛则生热，肾盛则生寒，肾虚则寒动于中，心虚则热伏于内。
李氏曰∶潮热有时为内伤、为虚热，无时为外感、为实。虚者，大温经汤。实者，四物汤加柴胡、黄芩。经闭者，
滋血汤。骨蒸者，大胡连丸、乌鸡丸。五心烦热，四物加胡连、川连。无汗者，茯苓补心汤。有汗者，加味逍遥散。
【脉】洪数有力是为实热，细数无力即是虚热。浮主外邪，沉乃里热，表里虚实，以此分别，脏腑经络，具
在脉诀。
平时发热
平时发热必偏阳，人瘦阴虚火自狂，能戒五辛如淡食，胜如煎服地黄汤。
临经发热
血去阴虚内热生，口干烦躁不和平，行过初至须分治，客实虚潮另有名。
劳热
因劳发热为劳热，肢体酸痛盗汗多，烦躁不宁神困倦，急投良剂免沉 。午前热属气分，清心莲子饮。午后
热属阴分，地黄汤。若劳心者，天王补心丹。劳力者，加味逍遥散。
客热
客热皆由元气虚，卫家浅薄外邪居，心烦口渴肌肤燥，加味逍遥治有余。《良方》曰∶经行体虚，温暖过度，
外邪乘之，故曰客热，其状上焦胸膈之间虚热，口燥心烦，手足壮热是也。
潮热
要知潮热阳明实，热至如潮不失期，若是太冲停瘀血，桃仁承气可行之。
实热
脉洪有力名为实，热在先前经未行，便闭唇焦兼口渴，可煎玉烛把衣更。
虚热
脉来无力便知虚，阴不足兮气有余，必是去多经水后，六神补血自能除。
寒热
寒热虽云外中风，阴虚阳弱不相同，更寻气血分虚实，寒热交争又一宗。经曰∶阳虚则恶寒，阴虚则发热，阳不
足则先寒后热，阴不足则先热后寒。阴阳不调之，故当分气血虚实治之。寸口脉微为阳不足，则阴气上入于阳中，宜
补中益气汤。尺部脉弱为阴不足，则阳气下陷于阴中，宜益阴地黄丸。若怒动肝火者，小柴胡汤。寒热交争，生地黄丸。
【歌诀】
因劳累而致的发热，常伴有神思疲惫、多困倦；
感受外邪客热，则见口燥及心烦；
内伤且有瘀血阻滞而成潮热；
外感发热无固定时间，热度时高时低；
平时经前若有实邪积滞需仔细查看；
经后出血过多则按虚证论治；
实证适宜用清热解表法，虚证适宜用温补法；
若出现寒战高热伴胡言乱语，则另立门类讨论。
【论述】
王太仆说：如果极度寒冷且严重，用温热药治疗却不回暖，这是命门火衰（无火），应当治疗心脏。如果发热来去无常，白天显现夜晚潜伏，夜晚发作白天停止，这也是命门火衰（无火），应当治疗心脏。如果极度炎热且严重，用寒凉药治疗却退不了热，这是肾阴亏虚（无水），应当资助肾脏。心气盛则生热，肾气盛则生寒，肾虚则寒气动于中焦，心虚则热气伏于内。
李氏说：有固定时间的潮热属于内伤、属于虚热；没有固定时间的发热属于外感、属于实热。虚证，用大温经汤（Da Wen Jing Tang）。实证，用四物汤（Si Wu Tang）加柴胡（Bupleuri Radix）、黄芩（Scutellariae Radix）。经闭者，用滋血汤（Zi Xue Tang）。骨蒸潮热者，用大胡连丸（Da Hu Lian Wan）、乌鸡丸（Wu Ji Wan）。五心烦热（手心、脚心及心胸烦热），用四物汤加胡连（Coptidis Rhizoma, 此处指黄连类）、川连（Coptidis Rhizoma）。无汗者，用茯苓补心汤（Fu Ling Bu Xin Tang）。有汗者，用加味逍遥散（Jia Wei Xiao Yao San）。
【脉诊】
脉象洪大数急且有力，是实热；
脉象细小数急且无力，即是虚热。
浮脉主外邪侵袭，沉脉主里热，通过脉象可以分辨表里虚实，脏腑经络的病变都包含在脉诀之中。
【平时发热】
平时发热必然偏向阳分，身体消瘦者阴虚导致虚火妄动，如果能戒除辛辣食物如同清淡饮食一样，胜过煎服地黄汤（Di Huang Tang）。
【临经发热】
月经来潮失血导致阴虚，内生虚热，出现口干烦躁、情绪不平和，行经初期与经后须分别治疗，外感实证与虚性潮热另有名称区分。
【劳热】
因劳累而发热称为劳热，肢体酸痛、盗汗多，烦躁不安、精神困倦，应紧急投用良剂以免病情沉重。午前发热属气分病，用清心莲子饮（Qing Xin Lian Zi Yin）。午后发热属阴分病，用地黄汤（Di Huang Tang）。若是用心过度者，用天王补心丹（Tian Wang Bu Xin Dan）。若是用力过度者，用加味逍遥散（Jia Wei Xiao Yao San）。
【客热】
客热皆由元气虚弱，卫气（Wei Qi，防御之气）浅薄导致外邪停留，出现心烦口渴、肌肤干燥，可用加味逍遥散（Jia Wei Xiao Yao San）治疗有余之邪。《良方》说：经期身体虚弱，保暖过度，外邪乘虚而入，所以叫客热，其症状表现为上焦胸膈之间虚热，口燥心烦，手足壮热。
【潮热】
要知道潮热多属阳明腑实，发热如潮水般定时而至不失期约，如果是太冲脉停瘀血，可用桃仁承气汤（Tao Ren Cheng Qi Tang）攻下瘀热。
【实热】
脉象洪大有力名为实热，发热在经前未行经时出现，伴有大便闭塞、嘴唇焦裂兼口渴，可煎服玉烛散（Yu Zhu San）以调和气血。
【虚热】
脉来无力便知为虚，阴液不足而阳气相对有余，必定是经后出血过多所致，六神补血（此处指代补血之法或方义，原文似缺方名或指代特定补血思路，依文意译为补血）自然能消除。
【寒热】
寒热虽说是外感中风所致，但阴虚阳弱的情况也不相同，更需探寻气血分辨虚实，寒热交争又是另一宗派。经文说：阳虚则恶寒，阴虚则发热，阳气不足则先寒后热，阴气不足则先热后寒。阴阳不调和，所以应当分气血虚实进行治疗。寸口脉微表示阳气不足，则阴气上入于阳中，宜用补中益气汤（Bu Zhong Yi Qi Tang）。尺部脉弱表示阴气不足，则阳气下陷于阴中，宜用益阴地黄丸（Yi Yin Di Huang Wan）。若是怒动肝火者，用小柴胡汤（Xiao Chai Hu Tang）。寒热交争者，用生地黄丸（Sheng Di Huang Wan）。
[Verse]
Heat due to overwork is often accompanied by mental fatigue and drowsiness;
External pathogenic heat causes dry mouth and irritability;
Internal injury with blood stasis leads to tidal fever;
External contraction fever has no fixed time, with fluctuating temperatures;
If there is excess accumulation before menstruation, it must be examined carefully;
Excessive bleeding after menstruation should be treated as deficiency;
Excess patterns are suitable for clearing heat and resolving the exterior, while deficiency patterns are suitable for warming and tonifying;
Chills, high fever, and delirium are discussed in a separate category.
[Discussion]
Wang Taipu said: If there is severe cold that does not respond to warming treatment, it indicates a lack of Mingmen Fire (Mingmen Fire Deficiency), and the Heart should be treated. If fever comes and goes unpredictably, appearing during the day and hiding at night, or occurring at night and stopping during the day, this also indicates a lack of Mingmen Fire (Mingmen Fire Deficiency), and the Heart should be treated. If there is extreme heat that does not respond to cooling treatment, it indicates Kidney Yin Deficiency (Kidney Water Deficiency), and the Kidneys should be assisted. Exuberant Heart Qi generates heat, exuberant Kidney Qi generates cold, Kidney Deficiency causes cold to move within the Middle Jiao, and Heart Deficiency causes heat to hide internally.
Li Shi said: Tidal fever with a fixed time belongs to internal injury and deficiency heat; fever without a fixed time belongs to external contraction and excess heat. For deficiency patterns, use Da Wen Jing Tang (Great Warming of the Menses Decoction). For excess patterns, use Si Wu Tang (Four Substances Decoction) added with Chai Hu (Bupleuri Radix) and Huang Qin (Scutellariae Radix). For amenorrhea, use Zi Xue Tang (Nourishing Blood Decoction). For bone-steaming fever, use Da Hu Lian Wan (Great Coptis Pill) and Wu Ji Wan (Black Chicken Pill). For five-palm heat (heat sensation in palms, soles, and chest), use Si Wu Tang added with Hu Lian (Coptidis Rhizoma) and Chuan Lian (Coptidis Rhizoma). For those without sweat, use Fu Ling Bu Xin Tang (Poria Nourishing Heart Decoction). For those with sweat, use Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder).
[Pulse Diagnosis]
A pulse that is surging, rapid, and forceful indicates excess heat;
A pulse that is fine, rapid, and weak indicates deficiency heat.
A floating pulse governs external pathogens, while a deep pulse governs interior heat; through the pulse, exterior/interior and excess/deficiency can be distinguished. The diseases of zang-fu organs and meridians are all contained in the Pulse Formulas.
[General Fever]
Fever occurring generally always leans towards the Yang aspect. In emaciated individuals, Yin Deficiency causes deficient fire to run rampant. If one abstains from pungent foods just as they would eat bland food, it is superior to decocting and taking Di Huang Tang (Rehmannia Decoction).
[Fever Before Menstruation]
Loss of blood during menstruation leads to Yin Deficiency and endogenous heat, causing dry mouth, irritability, and emotional instability. Treatment differs between the beginning and end of the flow; external excess and deficiency-type tidal fevers have distinct names.
[Overwork Fever]
Fever caused by labor is called overwork fever, characterized by limb soreness, abundant night sweats, restlessness, and mental fatigue. Good prescriptions should be administered urgently to prevent the condition from becoming severe. Fever in the morning belongs to the Qi aspect; treat with Qing Xin Lian Zi Yin (Clear Heart Lotus Seed Drink). Fever in the afternoon belongs to the Yin aspect; treat with Di Huang Tang (Rehmannia Decoction). For those who overuse their mind, use Tian Wang Bu Xin Dan (Emperor of Heaven's Heart-Nourishing Pill). For those who overexert physically, use Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder).
[External Contraction Fever]
External contraction fever arises from Yuan Qi (Original Qi) deficiency and shallow Wei Qi (Defensive Qi), allowing external pathogens to reside. Symptoms include irritability, thirst, and dry skin; Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder) treats the excess. *Liang Fang* states: During menstruation, when the body is weak and warmth is excessive, external pathogens take advantage, hence called "external contraction fever." Its presentation is deficient heat in the Upper Jiao chest and diaphragm, with dry mouth, irritability, and intense heat in the hands and feet.
[Tidal Fever]
One must know that tidal fever is often Yangming Excess. Fever arrives like the tide without missing its schedule. If it is due to blood stasis stopping in the Taichong channel, Tao Ren Cheng Qi Tang (Peach Kernel Cathartic Decoction) can be used.
[Excess Heat]
A surging and forceful pulse is named excess heat. Heat occurs before menstruation begins, accompanied by constipation, cracked lips, and thirst. Yu Zhu San (Jade Candle Powder) can be decocted to harmonize blood and qi.
[Deficiency Heat]
A weak pulse indicates deficiency. When Yin is insufficient and Qi is relatively excessive, it is certainly due to excessive bleeding after menstruation. Nourishing blood will naturally eliminate it.
[Chills and Fever]
Although chills and fever are said to be caused by external wind-stroke, cases of Yin Deficiency and Yang Weakness are different. One must further seek to distinguish excess and deficiency in Qi and Blood; chills and fever alternating is another category. The Classic says: Yang Deficiency causes aversion to cold, Yin Deficiency causes fever. Insufficient Yang leads to chills first then fever; insufficient Yin leads to fever first then chills. Because Yin and Yang are unharmonized, treatment should differentiate based on Qi and Blood excess and deficiency. A faint pulse at the Cun position indicates Yang insufficiency, where Yin Qi ascends into Yang; Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) is appropriate. A weak pulse at the Chi position indicates Yin insufficiency, where Yang Qi sinks into Yin; Yi Yin Di Huang Wan (Nourish Yin Rehmannia Pill) is appropriate. If anger stirs Liver Fire, use Xiao Chai Hu Tang (Minor Bupleurum Decoction). For alternating chills and fever, use Sheng Di Huang Wan (Raw Rehmannia Pill).
