黄帝问岐伯曰∶余闻皮有分部，（前说十五大络，循其行处以求其病。次说皮部十二络之以
十二经上之
以皮分十二部，以取其病，故曰皮有部也。）脉有经纪，（大络小络，总以十二大脉，以为皮部

夫络脉之见也，其五色各异，青黄赤白黑不同，其故何也？岐伯曰∶经有常色而络无常变。
（常，谓五色见者定是络色也。然五脏六腑之注定属五行，故脏腑大经各有常色。阴络随于阴经，

黄帝询问岐伯说：我听说皮肤有分部，（前面论述了十五个大络，沿着它们的循行部位来探求疾病。接着论述了十二皮部，将十二经脉之气散布于体表分为十二个部分，以通过观察皮部来诊察疾病，所以称为“皮有部”。）脉象有纲纪，（大络和小络，统属于十二条主要经脉，作为皮部的纲纪。）筋结有网络，（十二经筋，各自有结聚之处，各有包络。）骨骼有度量标准，（骨骼有大小长短的度量。）它们所引发的疾病各不相同，（因为皮、脉、筋、骨各不相同，所以皮、脉、筋、骨所患的疾病也不同。）辨别其分部，以及左、右、上、下、阴、阳所在的具体位置，（辨别在皮、脉、筋、骨分部中的不同之处，有左有右，有上有下，有阴有阳，这六种所在的位置。）疾病的开始与终结，（病邪客居在前述六个方面，有初起也有极盛之时。平按：《素问》中“终始”作“始终”。）希望听您讲讲其中的道理。
岐伯回答说：想要了解皮部，要以经脉为纲纪，所有经脉都是这样。（想要知道皮肤的各部区别，以十二经脉为纲纪。十二经的皮部络脉，都以此为例。平按：注释中的“部别”，袁刻本作“别部”。）阳明经的阳气，名叫“害蜚”，上下（手阳明和足阳明）遵循同样的法则，（蜚，音扶贵反。阳明大经为阳，所以大小络脉属于阳明之阳。阳明经脉有手经和足经，手经在上部（头面），足经在下部（下肢）。又因手阳明在手为下、在头为上；足阳明在头为上、在足为下。诊察颜色和施行针刺，方法都是一样的，其余类推。平按：《甲乙经》在“蜚”字下有“十二经”三字。）观察该部中有浮现在皮肤的络脉，都是阳明经的络脉，（浮，指大小络脉显现于皮肤表面。）如果颜色多青则疼痛，多黑则痹证，（络脉都有五色，但根据各络脉颜色偏多的情况来候察不同的疾病。邪气客居在分肉之间，逼迫肌肉刚开始疼痛，所以络脉呈青色。久留体内变为冷或热，或者导致麻木不仁而成痹证，所以络脉色深变黑。）多黄赤则热，（热邪炽盛于内，气溢于皮肤，所以络脉呈黄赤色。平按：《素问》、《甲乙经》无“多”字。）多白则寒，（垩白，代表寒。所以寒气在中，络脉呈白色。）五色都出现则是寒热错杂，（青、赤、黄等为阳色，白、黑两种为阴色，现在阴阳二色俱见，应当知道所患疾病有寒有热。）络脉充盛则病邪传入经脉，（盛，指大小络脉充盛。大小络脉中痛、痹、热、寒、寒热五种邪气盛者，则顺着络脉传入经脉。平按：《素问》、《甲乙经》在“入”字下有“客”字。）
阳络主外，阴络主内。（阳络主管外部，阴络主管内部。在阳络者主外，在阴络者主内。）少阳经的阳气，名叫“枢特”，上下遵循同样的法则，观察该部中有浮现在皮肤的络脉，都是少阳经的络脉，络脉充盛则病邪传入经脉，所以在阳者主内，在阴者主出，渗流入内部，所有经脉都是这样。（少阳络脉充盛则传入经脉，所以主内；经脉充盛外溢，所以主出。所有阴阳络脉主内出的规律，都可以以此类推。渗，音山荫反，意为下入。平按：“枢特”在《素问》中作“枢持”，《甲乙经》作“枢杼”，注云：一作持。“上下同法”四字，《甲乙经》没有。“络脉”二字中的“脉”字，《素问》、《甲乙经》均无。“主出”在《甲乙经》中作“主外”。注释下的“下入也”三字袁刻本脱漏。）太阳经的阳气，名叫“关枢”，上下遵循同样的法则，观察该部中有浮现在皮肤的络脉，都是太阳经的络脉，络脉充盛则病邪传入并客居于经脉。（外部充盛，则传入大经。）少阴经的阴气，名叫“枢儒”（而泉反。平按：《素问》作“儒”，新校正云：“《甲乙经》作‘’。”今本《甲乙经》仍作“儒”，正统本《甲乙经》作“”。日本丹波元简《素问识》认为“”音软，引用《仓颉篇》解释为柱上承斗的曲木。宜从《甲乙经》作“”。），上下遵循同样的法则，观察该部中有浮现在皮肤的络脉，都是少阴经的络脉，络脉充盛则病邪传入并客居于经脉，它进入经脉时，从阳部注入经脉，（从阳络部注入阳经。）经脉之气外出时，从阴部注入骨骼。（从阴络部外出注入阴经，向内注入骨骼，少阴主骨。平按：《素问》、《甲乙经》无“经”字。“阴”字下《素问》有“内”字，《甲乙经》有“部内”二字。）心主（心包）的阴气，名叫“害肩”，上下遵循同样的法则，观察该部中有浮现在皮肤的络脉，都是心主的络脉，络脉充盛则病邪传入并客居于经脉。太阴经的阴气，名叫“关枢”（平按：“关枢”在《素问》中作“关蛰”，新校正云：《甲乙》“蛰”作“执”。今本《甲乙》仍作“蛰”，正统本《甲乙经》作“执”，袁刻亦作“蛰。”），上下遵循同样的法则，观察该部中有浮现在皮肤的络脉，都是太阴经的络脉，络脉充盛则病邪传入并客居于经脉。凡是十二条经脉，是皮肤的分区。（皮肤有分部，是因为以十二脉分为各部。平按：“经脉者”在《素问》、《甲乙经》中作“经络脉者”。）
因此各种疾病的发生，下面广泛论述外邪主导百病的次第过程。必定先客居在皮毛，邪气侵袭人体则腠理开泄，开泄后则侵入络脉，停留不去，传入腑脏，禀受于肠胃。（外邪气，指风寒暑湿。邪气进入身体致病，首先附着于皮毛，停留不出，则腠理孔窍开放，趁机而入，即客居于络脉，络脉传入阳经，阳经传入六腑，于是禀承肠胃之气而形成百病。平按：《素问》、《甲乙经》在“络脉”下有“留而不去传入于经”八字。）邪气刚开始进入皮肤时，像冷水洒身一样毫毛竖起，腠理开泄：（ ，苏护反，流逆上也，谓寒邪逆入腠理也。外邪入身为病也，初着皮毛，能开腠理也。平按：《甲乙经》作“淅”。）它进入络脉时，则络脉充盛且颜色改变；（能使络脉充盛、颜色改变。）它客居于经脉时，则正气减损虚弱而脉象陷下；（正气减损为虚，进而血少脉陷。平按：“减”在《素问》中作“感”，道藏本作“盛”，《甲乙经》也作“盛”。）如果停留在筋骨之间，寒邪多则筋挛骨痛，热邪多则筋弛骨消，肌肉消瘦破裂，毛发干枯直立败坏。（循经进入筋骨之间，停留不去。寒邪不去则产生两种病：一是筋挛拘急，二是骨乃疼痛。若热邪不去则产生五种病：一是筋热缓弛，二是骨热消细，三是身肉消瘦，三烁，余药反，淫邪在肉也；四是破裂，五是毛发焦枯直立，五也。热邪如此客居于筋骨之间，最终会导致死亡。平按：“施”在《素问》、《甲乙经》中作“弛”。《甲乙经》作“ ”。注“淫邪在肉”，袁刻本“肉”作“内”。 字，袁刻本作“ ”。）
黄帝说：先生所说的皮的十二个部分，它们生病的情况是怎样的？岐伯说：皮是脉的分区，邪气客居在皮肤则腠理开泄，开泄后邪气就进入客居于络脉，络脉满盈则注入经脉，经脉满盈则进入并舍居于腑脏，所以皮肤有分部，如果不治疗就会生大病。（前面阐明邪气进入皮毛乃至禀受于肠胃，其次言邪气进入乃至筋骨之间，现在言邪气进入至于脏腑，都可以从浅至深，以至于大病，在浅表阶段不治疗，遂生大病。与，通“疗”。平按：“不与”今本《甲乙经》作“不愈”，正统本作“不与”，《素问》新校正云：“《甲乙经》不与作不愈，全元起本作不与，元起云：气不与经脉和调，则气伤于外，邪流入于内，必生大病也。本注与训疗，与元起所解亦异。”）黄帝说：好。
关于络脉的显现，其五色各异，青、黄、赤、白、黑不同，这是什么原因呢？岐伯说：经脉有常色而络脉无常变。（常，谓五色见者定是络色也。然五脏六腑之注定属五行，故脏腑大经各有常色。阴络随于阴经，色亦不改。阳络虽属阳经，以是阳脉之阳，故随时变也。平按：《甲乙经》无“青黄赤白黑不同”七字。络无常变正统本《甲乙经》作络脉无常变。）黄帝说：经脉的常色是怎样的？岐伯说：心色赤，肺色白，肝色青，脾色黄，肾色黑，这些都对应其经脉的颜色。（五脏五行之色皆合经脉，故经之色常应也。平按：注“常”下原缺一字，根据经文当作“应”。）黄帝说：络脉的阴阳，也对应其经脉吗？岐伯说：阴络的颜色对应其经脉。阳络的颜色变化无常，随着时令而行。（络有阴阳，阴络是阴之阴，故随经色不变；阳络是阳之阳，故随时变也。平按：时上《素问》、《甲乙经》均有四字。）寒邪多则血液凝涩，凝涩则呈青黑色，热邪多则血液濡润泽亮，濡润泽亮则呈黄赤色，这是正常的颜色，称为无病。（淖，丈卓反，濡甚也。解其阳络随时而变也，冬月寒甚，则经脉凝泣，凝泣不通，则阳络壅而青黑；夏日热甚，血气濡甚，则阳络热而黄赤也。阳络如此随四时而变者，此为阳络常色，谓之无病之候也。不可见而色见者，病也。平按：凝泣《素问》、《甲乙经》均作凝泣。淖泽今本《甲乙经》作 泽，正统本《甲乙》作淖泽。此其，《素问》其作皆。常色者，者字袁刻作也。注则经脉，则字袁刻作虽。）五色都出现，称为寒热错杂。黄帝说：好。（随一时中五色俱见者，此为寒热之病也。）
[Ping An]: This section, from the beginning to "and then a major illness arises, Huangdi said: Excellent," is found in *Suwen* (Treatise on Plain Questions), Volume 15, Chapter 56, "Pi Bu Lun" (Treatise on Skin Regions). From "Since the appearance of the collaterals and meridians" to the end, it is found in *Suwen*, Volume 15, Chapter 57, "Jing Luo Lun" (Treatise on Meridians and Collaterals). Additionally, from the beginning to the end, it is found in *Jiaying Jing* (The Systematic Classic of Acupuncture and Moxibustion), Volume 2, Part 1, Lower Section.
Huangdi asked Qibo: I have heard that the skin has distinct regions, (Previously, the fifteen great collaterals were discussed, seeking disease by following their pathways. Next, the twelve skin regions were discussed, dividing the Qi of the twelve meridians into twelve parts on the surface to diagnose disease by observing the skin regions, hence called 'skin has regions'.) the vessels have their organizing principles, (The great and small collaterals are collectively governed by the twelve main meridians, serving as the organizing principles for the skin regions.) the sinews have knots and networks, (The twelve sinew meridians each have points of knotting and respective envelopments.) and the bones have measurements, (Bones have measurements of size and length.) and the diseases they generate differ from one another, (Because the skin, vessels, sinews, and bones are distinct, the diseases arising in them differ.) distinguishing their regions, and the locations of left, right, upper, lower, yin, and yang, (Distinguishing the differences within the skin, vessel, sinew, and bone regions, there are left and right, upper and lower, yin and yang, these six types of locations.) the beginning and end of diseases, (Pathogenic factors reside in the aforementioned six aspects, having both an initial stage and an extreme stage. Ping An: 'Zhong Shi' [end and beginning] in *Suwen* is written as 'Shi Zhong' [beginning and end].) I wish to hear the principles regarding this.
Qibo replied: To understand the skin regions, one must take the meridians as the organizing principle; this applies to all meridians. (To know the distinctions of the skin regions, the twelve meridians serve as the organizing principle. The skin region collaterals of the twelve meridians all follow this example. Ping An: In the note, 'Bu Bie' [region distinction] is written as 'Bie Bu' [distinction of region] in Yuan's edition.) The Yang aspect of the Yangming meridian is named 'Hai Fei' (Flying/Ascending), and the upper and lower (Hand Yangming and Foot Yangming) follow the same method, (Fei, pronounced Fu Gui fan. The great channel of Yangming is Yang, so the great and small collaterals belong to the Yang aspect of Yangming. The Yangming meridian includes hand and foot channels; the hand channel is associated with the upper part (head/face), and the foot channel with the lower part (lower limbs). Furthermore, Hand Yangming is lower in the hand but upper in the head; Foot Yangming is upper in the head but lower in the foot. Diagnosing colors and performing acupuncture follow the same methods, and the rest can be inferred similarly. Ping An: *Jiaying Jing* has three characters 'Twelve Meridians' after 'Fei'.) Observe if there are floating collaterals in the region; these are all the collaterals of the Yangming meridian, (Floating refers to the great and small collaterals appearing on the skin.) if the color is predominantly blue/green, there is pain; if predominantly black, there is Bi syndrome (obstruction), (Collaterals exhibit five colors, but different diseases are predicted based on which color predominates in the various collaterals. When pathogenic factors lodge between the muscle layers, pressing on the muscles causing initial pain, the collateral appears blue/green. If lingering for a long time, becoming cold or hot, or leading to numbness and forming Bi syndrome, the collateral becomes deeply blue/black.) if predominantly yellow/red, there is heat, (Excessive heat inside causes Qi to overflow to the skin, so the collateral appears yellow/red. Ping An: The character 'Duo' [predominantly] is absent in *Suwen* and *Jiaying Jing*.) if predominantly white, there is cold, (White like chalk indicates cold. Thus, when cold qi resides inside, the collateral appears white.) if all five colors appear, there is alternating cold and heat, (Blue/green, red, and yellow are Yang colors; white and black are Yin colors. Since both Yin and Yang colors appear, one should know that the disease involves both cold and heat.) when the collaterals are full/excess, the pathogen enters the meridians, (Full/excess refers to the fullness of the great and small collaterals. When the five pathogens—pain, Bi, heat, cold, and alternating cold/heat—are excessive in the great and small collaterals, they enter the meridians along the collaterals. Ping An: *Suwen* and *Jiaying Jing* add the character 'Ke' [lodge/reside] after 'Ru' [enter].)
Yang collaterals govern the exterior, and Yin collaterals govern the interior. (Yang collaterals govern the exterior, Yin collaterals govern the interior. Those in the Yang collaterals govern the exterior, those in the Yin collaterals govern the interior.) The Yang aspect of the Shaoyang meridian is named 'Shu Te' (Pivot Special), and the upper and lower follow the same method. Observe if there are floating collaterals in the region; these are all the collaterals of the Shaoyang meridian. When the collaterals are full/excess, the pathogen enters the meridians; thus, what is in the Yang governs the interior, and what is in the Yin governs the exit, seeping into the interior; this applies to all meridians. (When Shaoyang collaterals are full/excess, they enter the meridians, thus governing the interior; when meridians are full/excess and overflow outward, they govern the exit. The rules of Yin and Yang collaterals governing entry and exit can be understood by this example. Shen, pronounced Shan Yin fan, means descending/entering. Ping An: 'Shu Te' in *Suwen* is 'Shu Chi' [Pivot Hold], and in *Jiaying Jing* is 'Shu Zhu' [Pivot Pin], noted as also 'Chi'. The four characters 'Shang Xia Tong Fa' [Upper and lower follow the same method] are absent in *Jiaying Jing*. The character 'Mai' [vessel] in 'Luo Mai' is absent in *Suwen* and *Jiaying Jing*. 'Zhu Chu' [govern exit] in *Jiaying Jing* is 'Zhu Wai' [govern exterior]. The three characters 'Xia Ru Ye' [means entering downward] are omitted in Yuan's edition.) The Yang aspect of the Taiyang meridian is named 'Guan Shu' (Gate Pivot), and the upper and lower follow the same method. Observe if there are floating collaterals in the region; these are all the collaterals of the Taiyang meridian. When the collaterals are full/excess, the pathogen enters and lodges in the meridians. (Exterior excess enters the great meridians.) The Yin aspect of the Shaoyin meridian is named 'Shu Ru' (Pivot Confucian/Pillar) (Er Quan fan. Ping An: *Suwen* writes 'Ru', Xin Zheng Jiao says: "*Jiaying Jing* writes ''. Current editions of *Jiaying Jing* still write 'Ru', orthodox edition writes ''. Danbo Yuanjian's *Suwen Shi* in Japan states '' sounds like 'Ruan', citing *Cangjie Pian* as the curved wood supporting the dipper on the pillar. It is advisable to follow *Jiaying Jing* writing ''. ), and the upper and lower follow the same method. Observe if there are floating collaterals in the region; these are all the collaterals of the Shaoyin meridian. When the collaterals are full/excess, the pathogen enters and lodges in the meridians. When entering the meridians, it flows from the Yang region into the meridians, (Flowing from the Yang collateral region into the Yang meridians.) and when exiting the meridians, it flows from the Yin region into the bones. (Exiting from the Yin collateral region into the Yin meridians, internally flowing into the bones; Shaoyin governs the bones. Ping An: The character 'Jing' [meridian] is absent in *Suwen* and *Jiaying Jing*. After the character 'Yin', *Suwen* has 'Nei' [inside], and *Jiaying Jing* has 'Bu Nei' [region inside].) The Yin aspect of the Heart Master (Pericardium) is named 'Hai Jian' (Shoulder Burden), and the upper and lower follow the same method. Observe if there are floating collaterals in the region; these are all the collaterals of the Heart Master. When the collaterals are full/excess, the pathogen enters and lodges in the meridians. The Yin aspect of the Taiyin meridian is named 'Guan Shu' (Gate Pivot) (Ping An: 'Guan Shu' in *Suwen* is 'Guan Zhe' [Gate Hibernation], Xin Zheng Jiao says: *Jiaying* 'Zhe' is 'Zhi'. Current *Jiaying* still writes 'Zhe', orthodox edition writes 'Zhi', Yuan edition also writes 'Zhe'.), and the upper and lower follow the same method. Observe if there are floating collaterals in the region; these are all the collaterals of the Taiyin meridian. When the collaterals are full/excess, the pathogen enters and lodges in the meridians. All twelve meridians are the regions of the skin. (Skin has regions because the twelve meridians divide them into parts. Ping An: 'Jing Mai Zhe' [Meridians are] in *Suwen* and *Jiaying Jing* is written as 'Jing Luo Mai Zhe' [Meridians and Vessels are].)
Therefore, the onset of all diseases, discussed extensively below regarding how external pathogens lead to various diseases in sequence, must first lodge in the skin and hair. When pathogenic factors invade, the interstices (Cou Li) open; once open, they enter the collaterals, stay without departing, transmit to the Fu organs, and assimilate into the stomach and intestines. (External pathogenic factors refer to wind, cold, summer-heat, and dampness. When pathogenic factors enter the body to cause disease, they first attach to the skin and hair. If they linger and do not exit, the pores of the interstices open, allowing entry, lodging in the collaterals. The collaterals transmit to the Yang meridians, and the Yang meridians transmit to the Six Fu organs, thereby assimilating the Qi of the stomach and intestines to form various diseases. Ping An: *Suwen* and *Jiaying Jing* have eight characters 'Liu Er Bu Qu Chuan Ru Yu Jing' [Stay without departing, transmit to the meridians] after 'Luo Mai' [collaterals].) When pathogenic factors initially enter the skin, bristles rise like being sprinkled with cold water, and the interstices open: ( , Su Hu fan, flowing upward against the flow, meaning cold pathogenic factors逆流 into the interstices. When external pathogenic factors enter the body to cause disease, initially attaching to skin and hair, they can open the interstices. Ping An: *Jiaying Jing* writes 'Xi'.) When they enter the collaterals, the collaterals become full/excess and the color changes; (Causing collaterals to become full/excess and color to change.) when they lodge in the meridians, Qi is diminished and becomes deficient, leading to sinking/collapse; (Diminished Qi is deficiency, leading to blood scarcity and sunken pulses. Ping An: 'Jian' [diminish] in *Suwen* is 'Gan' [feel/sense], Daozang edition writes 'Sheng' [excess/full], and *Jiaying Jing* also writes 'Sheng'.) If they remain between the sinews and bones, excessive cold causes sinew spasms and bone pain, while excessive heat causes sinews to relax and bones to atrophy, flesh to emaciate and rupture, and hair to become straight and decay. (Entering the sinews and bones along the meridians and remaining there. If cold pathogenic factors do not depart, two diseases arise: one is sinew spasm and stiffness, two is bone pain. If heat pathogenic factors do not depart, five diseases arise: one is sinew heat and relaxation, two is bone heat and atrophy, three is flesh emaciation, three Shuo, Yu Yao fan, evil pathogenic factors in flesh; four is rupture, five is hair dry and straight, five. Heat pathogenic factors lodging in the sinews and bones in this manner eventually lead to death. Ping An: 'Shi' in *Suwen* and *Jiaying Jing* is 'Chi' [relax]. *Jiaying Jing* writes ' '. Note 'Yin Xie Zai Rou' [evil pathogenic factors in flesh], Yuan edition writes 'Rou' as 'Nei'. Character , Yuan edition writes as ' '.)
Huangdi said: You spoke of the twelve regions of the skin, how do they become diseased? Qibo said: The skin is the region of the vessels. When pathogenic factors lodge in the skin, the interstices open; once open, the pathogen enters and lodges in the collaterals. When the collaterals are full, it transmits to the meridians; when the meridians are full, it enters and resides in the Fu and Zang organs. Therefore, the skin has regions. If not treated, major illnesses will arise. (Previously, it was clarified that pathogenic factors enter the skin and hair up to assimilating into the stomach and intestines; next, it was stated that pathogenic factors enter up to the sinews and bones; now it is stated that pathogenic factors enter up to the Fu and Zang organs. All can progress from shallow to deep, leading to major illness. If not treated at the shallow stage, major illness ensues. 'Yu' is synonymous with 'Liao' [treat]. Ping An: 'Bu Yu' [not treat/not heal] in current *Jiaying Jing* is 'Bu Yu' [not heal], orthodox edition writes 'Bu Yu'. *Suwen* Xin Zheng Jiao says: "*Jiaying Jing* 'Bu Yu' is written as 'Bu Yu' [not heal], Quan Yuanqi edition writes 'Bu Yu' [not treat]. Yuanqi said: If Qi does not harmonize with the meridians, Qi is damaged externally, and pathogenic factors flow inward, inevitably causing major illness. This note interprets 'Yu' as 'treat', differing from Yuanqi's explanation.) Huangdi said: Excellent.
Regarding the appearance of collaterals, their five colors differ, with blue/green, yellow, red, white, and black varying differently. What is the reason? Qibo said: Meridians have constant colors, while collaterals have variable colors. (Constant refers to the five colors seen being definite collateral colors. However, the Five Zang and Six Fu organs are fixedly assigned to the Five Elements, so the great meridians of the Zang and Fu organs each have constant colors. Yin collaterals follow Yin meridians, and their colors do not change. Although Yang collaterals belong to Yang meridians, as they are the Yang of Yang vessels, they change according to the times. Ping An: *Jiaying Jing* lacks the seven characters 'Qing Huang Chi Bai Hei Bu Tong' [blue/green, yellow, red, white, black differ]. 'Luo Wu Chang Bian' [collaterals have no constant change] in orthodox *Jiaying Jing* is written as 'Luo Mai Wu Chang Bian' [collateral vessels have no constant change].) Huangdi said: What are the constant colors of the meridians? Qibo said: The heart is red, the lungs are white, the liver is blue/green, the spleen is yellow, and the kidneys are black; all correspond to the colors of their respective meridians. (The colors of the Five Zang corresponding to the Five Elements all match the meridians, so the color of the meridians is constantly corresponding. Ping An: The original note is missing one character after 'Chang' [constant]; based on the text, it should be 'Ying' [correspond].) Huangdi said: Do the Yin and Yang of the collaterals also correspond to their meridians? Qibo said: The color of Yin collaterals corresponds to their meridians. The color of Yang collaterals changes without constancy, proceeding according to the seasons. (Collaterals have Yin and Yang. Yin collaterals are Yin of Yin, so they follow the meridian color without changing; Yang collaterals are Yang of Yang, so they change according to the times. Ping An: Four characters before 'Shi' [time/season] are present in *Suwen* and *Jiaying Jing*.) Excessive cold causes blood to congeal and stagnate; congealing and stagnating leads to blue/black colors. Excessive heat causes blood to be moist and lustrous; moist and lustrous leads to yellow/red colors. These are normal colors, called indicating no disease. (Nao, Zhang Zhuo fan, extremely moist. Explaining that Yang collaterals change according to the times: in winter when cold is severe, meridians congeal and stagnate; congealing and stagnating blocks flow, causing Yang collaterals to be obstructed and appear blue/black; in summer when heat is severe, blood and Qi are extremely moist, causing Yang collaterals to be hot and appear yellow/red. When Yang collaterals change according to the four seasons in this way, this is the normal color of Yang collaterals, called the sign of no disease. Colors appearing where they should not are signs of disease. Ping An: 'Ni Qi' [congeal and stagnate] in *Suwen* and *Jiaying Jing* is written as 'Ni Qi'. 'Nao Ze' in current *Jiaying Jing* is 'Ze', orthodox edition writes 'Nao Ze'. 'Ci Qi' [this is], *Suwen* writes 'Qi' as 'Jie' [all]. 'Chang Se Zhe' [normal color ones], the character 'Zhe' in Yuan edition is 'Ye' [particle]. Note 'Ze Jing Mai' [then meridians], the character 'Ze' in Yuan edition is 'Sui' [although].) If all five colors appear together, it is called alternating cold and heat. Huangdi said: Excellent. (If all five colors appear simultaneously in one season, this is a disease of alternating cold and heat.)
