指纹何故乍然浮，邪在皮肤未足愁。腠理不通名表证，急行疏解汗之投。
（此纹与太渊脉相通，凡有外邪，太渊脉浮，此纹亦浮。盖邪在皮毛腠理之间，故指纹亦显露于外，谓之表
证。速宜疏散，启其皮毛，开其腠理，使邪随微汗而解，一匕成功，何嫌而不投哉？）
忽尔关纹渐渐沉，已知入里病方深。莫将风药轻相试，须向阳明里证寻。
（指纹见沉，知邪入里，但有浅深之别。若往来寒热，指纹半沉，尚在阳明胃经，治宜解肌；若外证壮热不
已，指纹极沉，已入阳明胃腑，速宜攻下。庸妄见其身热，犹以风药治之。盖病在内，治其外，非其治也。不
特病邪不服，适足以燥其阴血，愈增其困耳。）
身安定见红黄色，红艳多从寒里得。淡红隐隐本虚寒，莫待深红化为热。
（神气泰宁，荣卫静谧，定见太平景象。盖黄为中和之气，红为衣冠文物之色，红黄隐隐，景物熙熙，焉有不安
之理！寒邪初入皮毛，经络乍滞，所以纹见红鲜，由血滞也，无论内寒外寒，初病久病，一见此纹，总皆寒证。
凡人中气怯弱，荣卫不充，纹色必淡，淡而兼红，虚寒之应。至谓深红化热，其理安在？红
本寒因，岂能化热？由其寒闭皮毛，腠理不通。盖人身五内之气，时与皮毛之气相通贯，无一息之暂停。今寒
闭汗孔，内出之气无所泄，郁于皮毛之间，渐积渐浓而化为热矣。此内出之气为热，非外受之寒能变热也。）
关纹见紫热之征，青色为风古所称。伤食紫青痰气逆，三关青黑祸难胜。
（荣行脉中，卫行脉外。热壅经络，阻其阴荣之道，所以纹紫。紫为热炽，千古定评也。少阳甲木，其色本
青，肝胆受邪，纹见青色，此伤风候也，但可以风热称之，不可称惊风以误世，夫青者木之色，《内经》有在
天为风，在地为木之言，所以风木同气，肝受风邪纹必见青，此理最明最显。而幼科偏不言青为风，偏言青为惊。
据幼科所论，惊出于心，然青非心之色，何以青为惊乎？此等牵强之说，最为谬误。予有惊风辟妄，详列二卷。
紫而兼青，食伤之候。盖食饮有形之物，阻抑中焦，壅遏脾气，不能宣布，故风木乘其困而侮之，所以痰气上
逆也。疏通壅滞，令其流利可也。倘抑郁既久，脾气愈不运，荣卫愈见涩，则风痰实热，固结中焦，所以青而
兼黑，此抑郁之至也，急宜攻下，庶有生机，误认惊风，百无一救。）
指纹为何突然浮起？这是因为邪气在皮肤表层，尚不足为忧。腠理不通称为表证，应当立即使用疏风解表、发汗的药物进行治疗。
（此处的指纹与太渊脉相通，凡是有外邪侵袭，太渊脉呈现浮象，此处的指纹也会随之浮起。因为邪气停留在皮毛和腠理之间，所以指纹也显露于外部，这被称为表证。此时应迅速进行疏散治疗，开启皮毛，疏通腠理，使邪气随着微微出汗而解除，一次用药即可成功，有什么理由不投用呢？）
指纹忽然在关部逐渐变沉，说明邪气已经入里，病情才刚刚深入。不要随意尝试使用祛风药物，必须向阳明经的里证方向寻求治疗方法。
（指纹呈现沉象，可知邪气已入里，但有浅深之别。如果出现往来寒热，指纹半沉，邪气尚在阳明胃经，治疗宜用解肌法；如果外部症状表现为持续高热不退，指纹极沉，邪气已深入阳明胃腑，应立即采用攻下法。庸医妄见患者身热，仍然用祛风药治疗。因为病在内，却治其外，这不是正确的治法。不仅病邪不能消除，反而足以耗伤阴血，更加重病情。）
身体安定时，指纹呈现红黄色，艳红色多从寒证中获得。淡红色隐隐约约本是虚寒之象，不要等到深红色转化为热证时才处理。
（神气安宁，营卫静谧，定能呈现出太平的景象。黄色是中和之气，红色是衣冠文物的颜色，红黄隐隐，景象和煦，怎么会有不安的道理呢！寒邪刚侵入皮毛，经络暂时阻滞，所以指纹呈现鲜红色，这是由于血液滞涩所致。无论是内寒还是外寒，无论是初病还是久病，一见到这种指纹，总归都是寒证。凡是人体中气怯弱，营卫不充盛，指纹颜色必然淡薄，淡色兼有红色，是虚寒的表现。至于说深红色会转化为热证，道理在哪里呢？红色本源于寒因，怎么能转化为热呢？这是因为寒邪闭塞了皮毛，腠理不通。人体的五脏之气，时刻与皮毛之气相通贯注，没有一刻的暂停。现在寒邪闭塞了汗孔，体内排出的气体无处宣泄，郁积在皮毛之间，逐渐积聚浓重而化为热。这是体内排出的气体化为热，而不是外受的寒邪能变成热。）
关部指纹呈现紫色是热证的征兆，青色为风邪在古代就被称道。伤食导致紫青色，痰气上逆，三关出现青黑色则灾祸难胜。
（营气行于脉中，卫气行于脉外。热邪壅塞经络，阻断了营阴运行的通道，所以指纹呈紫色。紫色代表热势炽盛，这是千古确定的评价。少阳甲木的本色是青色，肝胆受到邪气侵袭，指纹呈现青色，这是伤风的征候，只能称之为风热，不能称之为惊风以免误导世人。青色是木的颜色，《内经》有“在天为风，在地为木”的说法，所以风与木同气，肝受风邪侵袭，指纹必然呈现青色，这个道理最明显。然而儿科医生偏偏不说青色代表风，偏要说青色代表惊。根据儿科医生的论述，惊出于心，但青色不是心的颜色，为什么青色代表惊呢？这种牵强附会的说法，最为谬误。我有《惊风辟妄》一文，详细列于第二卷。紫色兼有青色，是伤食的征候。饮食是有形的物体，阻碍压抑中焦，壅遏脾气，使其不能正常布散，所以风木之气乘其困顿而反侮脾土，导致痰气上逆。应当疏通壅滞，使其流利通畅。如果抑郁时间既久，脾气更加不运化，营卫更加涩滞，那么风痰实热就会固结在中焦，所以青色兼带黑色，这是抑郁到了极点，应当紧急采用攻下法，或许还有生机，如果误认为是惊风，百无一救。）
Why does the fingerprint suddenly float? This is because the pathogenic factor is in the skin layer, which is not yet a cause for concern. Obstruction of the couli (pores and interstices) is termed Exterior Syndrome (Biao Zheng). One should immediately administer herbs that disperse wind and release the exterior to induce sweating.
(The fingerprint here communicates with the Taiyuan pulse. Whenever there is an external pathogenic invasion, the Taiyuan pulse presents as floating, and this fingerprint also becomes floating. Since the pathogen resides between the skin/hair and the couli, the fingerprint also manifests externally, which is called Exterior Syndrome. At this stage, rapid dispersal treatment is required to open the skin/hair and unblock the couli, allowing the pathogen to be resolved through slight sweating. Success can be achieved with a single dose; what reason is there not to administer it?)
If the fingerprint at the Guan position gradually becomes sunken, it indicates that the pathogen has entered the interior, and the disease is just beginning to deepen. Do not casually attempt to use wind-dispelling herbs; one must seek treatment based on Interior Syndromes of the Yangming channel.
(A sunken fingerprint indicates that the pathogen has entered the interior, though there are distinctions in depth. If there is alternating fever and chills, and the fingerprint is half-sunken, the pathogen remains in the Yangming Stomach Channel; treatment should focus on resolving the muscle layer. If external symptoms show persistent high fever, and the fingerprint is extremely sunken, the pathogen has deeply entered the Yangming Stomach Organ; rapid purgation is required. Quack doctors, seeing body heat, still treat with wind-dispelling herbs. Because the disease is internal, treating the exterior is incorrect therapy. Not only will the pathogen not subside, but it will also dry up yin blood, exacerbating the condition.)
When the body is stable, the fingerprint appears red and yellow; bright red often arises from cold syndromes. Faintly visible pale red originally indicates deficiency-cold; do not wait until deep red transforms into heat syndrome.
(With tranquil spirit and quiet Ying-Wei [nutritive and defensive qi], a state of peace is established. Yellow represents the harmonious qi, and red represents the color of ceremonial attire. When red and yellow appear faintly together, the scene is harmonious; how could there be instability? When cold pathogen first invades the skin/hair, meridians temporarily stagnate, causing the fingerprint to appear fresh red due to blood stasis. Whether it is internal or external cold, whether early or late stage, seeing this fingerprint always indicates a cold syndrome. In individuals with weak middle qi and insufficient Ying-Wei qi, the fingerprint color must be pale. Pale combined with red is a sign of deficiency-cold. As for the idea that deep red transforms into heat, where is the logic? Red originates from cold; how can it transform into heat? It is because cold closes the skin/hair and obstructs the couli. The qi of the five zang organs constantly communicates with the qi of the skin/hair without pause. Now, cold blocks the sweat pores, so the qi exiting internally has no outlet, accumulating between the skin/hair, becoming denser and eventually transforming into heat. This heat is generated by the internally exiting qi, not by the externally acquired cold transforming into heat.)
A purple fingerprint at the Guan position is a sign of heat; green has been attributed to wind since ancient times. Food retention causes purple-green colors, and rebellious phlegm-qi follows. Green-black across the three segments brings unbearable disaster.
(Ying qi flows within the vessels, while Wei qi flows outside. Heat congestion in the meridians blocks the pathway of ying-nutritive flow, resulting in a purple fingerprint. Purple signifies blazing heat, a verdict confirmed through ages. Shaoyang Jia Wood naturally corresponds to the color green. When the Liver and Gallbladder are affected by pathogens, the fingerprint appears green, indicating Wind-Cold/Wind-Heat syndrome. It should be called Wind-Heat, not "Jing Feng" [Startled Wind/Convulsion] to avoid misleading the world. Green is the color of Wood. The *Neijing* states, "In heaven it is Wind, on earth it is Wood." Thus, Wind and Wood share the same qi; when the Liver is affected by Wind pathogen, the fingerprint must appear green—a very clear principle. However, pediatricians insist that green does not represent Wind, but rather Jing [Startle]. According to their theory, Jing originates from the Heart, yet green is not the color of the Heart; why does green represent Jing? Such forced explanations are most erroneous. I have written "Refutation of Baseless Claims on Startled Wind," detailed in Volume 2. Purple combined with green indicates food injury. Food, being有形 (substantial), obstructs the Middle Jiao, stifling Spleen Qi and preventing its dissemination. Consequently, Wind-Wood takes advantage of this distress to overact upon Earth, leading to rebellious phlegm-qi. Treatment should focus on unblocking stagnation to restore smooth flow. If depression persists, Spleen Qi fails to transport further, and Ying-Wei flow becomes more stagnant. Then, Wind-Phlegm Excess-Heat consolidates in the Middle Jiao, resulting in green mixed with black, representing extreme depression. Urgent purgation is needed to preserve life; mistaking this for Startled Wind leaves less than one in a hundred chances of survival.)
