(瘵有鬼，鬼病当祭，故瘵从之。《葛氏钤方》有祭炼法，以癸亥夜半跪祷北斗，皆祭
瘵法。若果有瘵鬼，亦是孽冤为祟，药石云何)
《良方》云∶骨蒸劳者，由积热附于骨而然也(此至脉之病也。夫肾主骨，骨至于蒸，
真阴
竭矣。阳何以根据而传各经，此病是孽)。亦曰传尸 ，复连无辜，其名不一。此病皆由脾
胃所致。其形羸瘦腹胀，泻痢，肢体无力，传于肾则盗汗不止，腰膝冷痛，梦与鬼交，小
便黄赤。传于心则心神忪悸，喜怒不时，颊唇赤色，作寒作热。传于肺则胸满短气，咳嗽吐
痰，皮肤甲错。传于肝则两目昏暗，胁下妨痛，闭户忿怒。五脏既病，则难治疗。
《大全》云∶妇人血风劳症(肝热生风，故病名血风。曰劳者，病久血虚，月候不行，
而发
热不止也)，因气血素虚，经候不调，或外伤风邪，内挟宿冷，致使阴阳不和，经络痞涩，
腹中坚痛，四肢酸疼，月水或断或来，面色萎黄羸瘦。又有产后未满百日，不谨将护，脏腑
虚忪，百脉枯竭，遂致劳损，久不瘥则变寒热，休作有时，饮食减少，肌肤瘦瘁，遇经水当
至则头目昏眩，胸背拘急，四肢疼痛，身体烦热，足重面浮，或经水不通，故谓之血风劳气
也。
按薛氏曰∶东垣云喜怒不节，起居不时，有所劳伤，皆损其气。气衰则火旺，火旺则秉
其脾
土，脾主四肢，故困热懒言，动作喘乏，表热自汗，心烦不安。当病之时，宜安心静坐，存
养其气，以甘寒泻其热气，以酸味收其散气，以甘温补其中气。经云∶劳者温之，损者益之
。《要略》云∶平人脉大为劳，以黄 建中汤主之(此是劳伤元气，乃脾肺气虚，非血风劳
也。当从损治。血风劳者，乃肝血虚风，热而成劳也。风劳冷劳因虚乘袭，日久变成劳热。
气虚者气不足，热劳者血不足。至骨蒸劳瘵，大都难治矣)。
（瘵病被认为有“鬼”作祟，若是鬼病应当祭祀，因此“瘵”字从“疒”旁加“责”或关联祭祀之意。《葛氏钤方》中有祭炼之法，即在癸亥日的半夜跪拜祈祷北斗星君，这都是祭祀瘵病的仪式。如果真的有瘵鬼，那也是由于冤孽因果造成的灾祸，药物又怎么能起作用呢？）
《良方》说：骨蒸劳，是由于积热附着在骨骼上而形成的（这是涉及脉象和病机的病症。肾主司骨骼，骨骼出现蒸热的感觉，说明真阴已经枯竭。阳气失去了依附的基础，从而传变到各个经络，这种病属于冤孽所致）。也称为传尸、复连、无辜等，名称不一。这种病都是由脾胃功能失调引起的。患者形体消瘦、腹部胀满、腹泻痢疾、四肢无力；病邪传入肾脏，则导致盗汗不止、腰膝冷痛、梦中与鬼交合、小便黄赤；传入心脏，则心神惊悸、喜怒无常、脸颊嘴唇发红、忽冷忽热；传入肺脏，则胸部胀满、呼吸短促、咳嗽吐痰、皮肤干燥如鳞甲；传入肝脏，则两眼昏花、胁肋部疼痛不适、关起门来容易愤怒。五脏都受到病变影响后，就难以治疗了。
《大全》说：妇女血风劳症（肝经有热而生风，所以病名叫做血风。称为“劳”，是因为病程长久导致血虚，月经停止不来，并且发热不止），这是由于气血原本虚弱，月经周期不调，或者外感风邪，内挟宿有的寒邪，致使阴阳不和，经络阻滞涩滞，腹部坚硬疼痛，四肢酸痛，月经有时断绝有时来潮，面色萎黄、形体消瘦。又有产后未满一百天，如果不谨慎调养护理，脏腑空虚惊悸，全身血脉枯竭，于是导致劳损，久治不愈就会变成寒热往来，发作有定时，饮食减少，肌肤瘦弱憔悴，遇到月经该来的时候，则头目昏眩，胸背部拘急紧张，四肢疼痛，身体烦热，脚重脸肿，或者月经不通畅，所以称之为血风劳气。
按薛己的说法：李东垣曾说，喜怒没有节制，起居没有规律，有所劳伤，都会损伤元气。气衰弱则火旺，火旺则克制脾土，脾主四肢，所以感到困倦发热、懒于言语，活动时气喘乏力，体表发热、自汗，心烦不安。在患病期间，应当安心静坐，涵养元气，用甘寒的药物清泻热气，用酸味的药物收敛耗散之气，用甘温的药物补益中气。《内经》说：劳损的病要用温补的方法，亏损的病要加以补益。《金匮要略》说：平人脉象大而无力是劳病，用黄芪建中汤主治（这是劳伤元气，属于脾肺气虚，不是血风劳。应当按照虚损来治疗。血风劳，是肝血虚生风，因热而成劳。风劳、冷劳是因虚而受邪侵袭，日久变成劳热。气虚是气不足，热劳是血不足。至于骨蒸劳瘵，大多都很难治疗了）。
(Chai disease [consumptive disease] is believed to be caused by "demons"; if it is a demon illness, sacrifices should be performed; hence the character for Chai implies connection to sacrificial rites. *Ge Shi Qian Fang* [The Key Prescriptions of Ge's Family] contains methods of ritual purification and sacrifice, specifically kneeling in prayer to the Big Dipper at midnight on the Guihai day; these are all rituals for sacrificing to cure Chai disease. If there truly were a Chai demon, it would also be a manifestation of karmic retribution or ancestral grievances, so how could medicinal herbs have any effect?)
*Liang Fang* [Excellent Prescriptions] states: Bone-steaming Lao [chronic consumptive syndrome with bone-heat] arises from accumulated heat attaching to the bones (This involves pathology related to pulse diagnosis. The Kidney governs the bones; when the bones feel steaming hot, it indicates that the True Yin [essential bodily fluids and cooling energy] has been exhausted. Yang Qi loses its foundation and transmission to various meridians; this disease is attributed to karmic retribution). It is also called Chuanshi [transmitted corpse/consumption], Fulian [repeated infection], and Wugu [innocent victim], with various names. This disease is primarily caused by dysfunction of the Spleen and Stomach. Symptoms include emaciation, abdominal distension, diarrhea and dysentery, and limb weakness. If the pathogen transmits to the Kidney, it causes night sweats that do not stop, cold pain in the lower back and knees, dreams of sexual intercourse with spirits, and yellow-red urine. If it transmits to the Heart, it causes palpitations and mental restlessness, irregular emotions (anger or joy), redness of the cheeks and lips, and alternating sensations of cold and heat. If it transmits to the Lung, it causes chest fullness, shortness of breath, coughing with phlegm, and skin resembling fish scales (dry and scaly). If it transmits to the Liver, it causes dim vision, painful obstruction in the hypochondrium, and irritability leading one to close doors and become angry. Once the Five Zang Organs are diseased, treatment becomes difficult.
*Dà Quán* [Great Collection] states: Women's Xuefeng Lao [Blood-Wind Consumptive Syndrome] (Heat in the Liver generates Wind, hence the name Blood-Wind. It is called Lao because prolonged illness leads to Blood deficiency, cessation of menstruation, and persistent fever). This occurs due to pre-existing deficiency of Qi and Blood, irregular menstruation, external contraction of Wind pathogens, and internal retention of chronic Cold. This results in disharmony of Yin and Yang, and stagnation/obstruction of the meridians. Symptoms include hard and painful abdomen, soreness and pain in the four limbs, intermittent menstruation, sallow complexion, and emaciation. Additionally, within 100 days postpartum, if care is not taken, the Zang-Fu organs become deficient and palpable, and all vessels become depleted, leading to consumptive damage. If not cured for a long time, it transforms into alternating chills and fever with regular intervals, reduced appetite, emaciated skin and muscle, dizziness and blurred vision upon the expected arrival of menstruation, stiffness and tension in the chest and back, pain in the four limbs, body heat and vexation, heavy legs, and facial edema, or amenorrhea. Hence it is called Xuefeng Laoqi [Blood-Wind Consumptive Qi].
According to Xue Ji: Li Dongyuan stated that unregulated emotions, irregular daily routines, and physical overexertion all damage Qi. When Qi declines, Fire flares up; when Fire flares, it controls Spleen Earth. Since the Spleen governs the four limbs, the patient feels fatigued and hot, reluctant to speak, panting and fatigued upon movement, with surface heat and spontaneous sweating, and mental restlessness. During the illness, one should sit quietly with a calm mind to nourish Qi, use Sweet-Cold herbs to drain Heat, use Sour herbs to astringe scattered Qi, and use Sweet-Warm herbs to tonify Middle Qi. The Classics state: For Lao [exhaustion], use warming methods; for Sun [deficiency], use tonifying methods. *Jin Gui Yao Lue* [Essential Prescriptions of the Golden Cabinet] states: A normal person with a large but weak pulse suffers from Lao disease, treated with Huangqi Jianzhong Tang [Astragalus Decoction to Build the Middle]. (This refers to injury to Original Qi, constituting Spleen and Lung Qi deficiency, not Xuefeng Lao. It should be treated as a deficiency condition. Xuefeng Lao is caused by Liver Blood deficiency generating Wind and Heat leading to consumption. Feng Lao [Wind Consumptive Syndrome] and Leng Lao [Cold Consumptive Syndrome] arise from deficiency allowing pathogenic invasion, transforming into Heat-Lao over time. Qi deficiency means insufficient Qi; Heat-Lao means insufficient Blood. As for Guzheng Lao Zhai [Bone-Steaming Consumptive Disease], most cases are difficult to treat.)
