寇宗 云∶凡看妇人病,入门先问经期。张子和云∶凡看妇病,当先问娠。又云∶凡治妇病
,不可轻用破气行血之药,恐有娠在疑似间也。彭用先云∶凡看产后病,须问恶露多少有无
。此妇科要诀也。沈芊绿云∶婴儿脏气未全,不胜药力,周岁内非重症,勿轻易投药,须酌
法治之,即两三岁内,形气毕竟嫩弱,用药不可太猛,峻攻峻补,反受药累。此幼科之要诀
也。王洪绪云∶痈与疽截然两途,红肿为痈,治宜凉解;白陷为疽,治宜温消。又云∶惟疔
用刺,其余概不轻用刀针,并禁升降痛烂二药。此外科要诀也。
《伤寒论》六经提纲,大半是凭乎问者。至如少阳病,口苦咽干目眩,及小柴胡汤症,往来
寒热,胸胁苦满,默默不欲饮食,心烦喜呕等,则皆因问而知,此孙真人所以未诊先问也。
大肠脉候左寸,小肠脉候右寸,此《脉诀》之言也。自滑伯仁候大小肠于两尺,李士材称为
“千古只眼”,后人遂皆信之。余考汪石山《脉诀刊误》,辨正叔和之说甚多,而独于“左
寸候心、小肠,右寸候肺、大肠”,未尝以为非,谓以腑配脏,二经脉相接,故同一部也。又
昌邑黄坤载元御,谓脉气上行者,病见于上,脉气下行者,病见于下。手之三阳,从手走头
,大小肠位居至下,而脉则行于至上,故与心、肺同候于两寸。其说亦精,可正滑说之误。
杨仁斋谓脉沉细、沉迟、沉小、沉涩、沉微之类,皆为阴;沉滑、沉数、沉实、沉大之
皆为阳。一或误施,死生反掌。余谓亦有不尽然者,按《名医类案·火热门》,壶仙翁治风
热不解,两手脉俱伏,时瘟疫大行,他医谓阳证见阴不治,欲用阳毒升麻汤升提之。翁曰∶
此风热之极,火盛则伏,非时疫也,升之则死矣。投连翘凉膈之剂,一服而解。又按《脉诀
》歌谓伤寒一手脉伏曰单伏,两手曰双伏,不可以阳证见阴为诊,乃火邪内郁,不得发越,
阳极似阴,故脉伏,必有大汗而解。时证见此脉不少,习医者宜审之,不可专主杨氏之说而
仲景《伤寒论》结胸热实,脉沉而紧,心下痛,按之石硬者,大陷胸汤主之。《金匮》
疝绕脐痛,若发则白津出,手足厥冷,其脉沉紧者,大乌头煎主之。同一沉紧之脉,一则属
热,一则属寒,然则临证者,岂可专凭脉乎?
《上海县志·艺术门》载姚蒙善医,尤精太素脉,邹来学巡抚召之视疾,姚曰∶公根器
有一窍出汗水。邹大惊曰∶此余秘疾,汝何由知?姚曰∶以脉得之,左关滑而缓,肝第四叶
有漏通下故也。邹求药。曰∶不须药,到南京便愈。以手策之曰∶今是初七,约十二日可到
。邹即行,果十二日晨抵南京而卒。夫预决死期,脉理精者能之,至因关脉之滑而缓,知其

李东璧《奇经考》云∶凡八脉不拘制于十二正经,无表里配合,故谓之奇。盖正经犹夫
,奇经犹夫湖泽,正经之脉隆盛,则溢于奇经,故秦越人比之天雨降下,沟渠溢满, 霈妄

脉象虚实疑似之间,最难审察。叶思兰治一产妇医案有云∶凡诊脉遇极大极微者,最宜
。如极大而无力,须防阳气浮散于外。如极微之脉,久久寻而得之,于指稍稍加力,按之至骨
愈坚牢者,不可认作虚寒。今此症六部皆无脉,尺后则实数有力,所谓伏匿脉也。阳匿于下
,亢之极矣,岂可泥于产后禁用寒凉哉?其辨别脉象、至为精细,为医者当熟复其言。
鬼祟之脉,忽大忽小,忽数忽迟。虫症之脉,乍大乍小。盖皆无一定之形也。至若气郁
之症,每因脉道不利,迟数不调,最宜审察。虚者之脉,亦有至数不齐者。《汪石山医案》

《汪石山医案》载∶王宜人产后因沐浴,发热呕恶,渴欲饮冷水瓜果,谵语若狂,饮食

寇宗奭说:凡是诊治妇女疾病,进门后首先要询问月经情况。张子和说:凡是诊治妇科病,应当先询问是否怀孕。他又说:凡是治疗妇女疾病,不可轻易使用破气行血的药物,恐怕患者处于疑似怀孕的状态。彭用先说:凡是诊治产后病,必须询问恶露的多少及有无。这是妇科的要诀。沈芊绿说:婴儿脏腑之气尚未发育完全,承受不住药力,周岁以内如果不是重症,不要轻易投药,必须斟酌法治之;即使是两三岁以内的儿童,形体和正气毕竟嫩弱,用药不可太猛烈,峻猛攻伐或峻猛温补,反而会让患者受药物拖累。这是儿科的要诀。王洪绪说:痈与疽是截然不同的两条路径,红肿的是痈,治疗宜用清凉解毒;白陷的是疽,治疗宜用温通消散。他又说:只有疔疮可以用针刺法,其余一概不轻易用刀针,并禁止使用导致疼痛溃烂的药物。这是外科的要诀。
《伤寒论》中六经病的提纲证,大半是通过问诊获得的。至于像少阳病出现的口苦、咽干、目眩,以及小柴胡汤证出现的往来寒热、胸胁苦满、默默不欲饮食、心烦喜呕等症状,都是因为问诊才知道的,这就是孙思邈强调“未诊先问”的原因。
大肠的脉象候于左寸,小肠的脉象候于右寸,这是《脉诀》中的说法。自从滑伯仁将大小肠的脉象候于两尺部,李士材称赞这是“千古只眼”,后人便都相信了这种说法。我考证汪石山的《脉诀刊误》,其中辨正王叔和的说法很多,唯独对于“左寸候心与小肠,右寸候肺与大肠”这一观点,未曾认为有误,他认为以腑配脏,这两条经脉相接,所以同一部位候诊。另外,昌邑人黄坤载(名元御)认为,脉气上行者,病见于上部;脉气下行者,病见于下部。手三阳经从手走向头部,大小肠位居身体最下部,而脉气则行于上部,所以与心、肺一同候诊于两寸部。他的说法也很精辟,可以纠正滑伯仁说法的错误。杨仁斋认为脉象沉细、沉迟、沉小、沉涩、沉微等,都属于阴;沉滑、沉数、沉实、沉大等,都属于阳。一旦误施治疗,生死就在反掌之间。我认为也有不完全如此的情况,查阅《名医类案·火热门》,壶仙翁治疗风热不解,两手脉象俱伏,当时瘟疫盛行,其他医生认为阳证出现阴脉是不治之症,想用阳毒升麻汤来升提阳气。壶仙翁说:这是风热之极,火盛导致脉伏,不是时疫,如果升提就会致死。于是投用连翘凉膈散之类的药剂,一服就解除了病症。又查《脉诀》歌诀说,伤寒一手脉伏叫单伏,两手脉伏叫双伏,不能因为阳证见阴脉就诊断为不治,这是因为火邪内郁,不得发越,阳极似阴,所以脉伏,必然会有大汗而解。时行疫病见此脉象不少,习医者应当审慎考察,不可专门信奉杨氏之说。
张仲景《伤寒论》中结胸热实证,脉沉而紧,心下痛,按之如石头般坚硬,用大陷胸汤主治。《金匮要略》中疝气绕脐痛,发作时流白津,手足厥冷,脉沉紧的,用大乌头煎主治。同样是沉紧的脉象,一个属于热证,一个属于寒证,那么临证时,怎么能专门凭借脉象呢?
《上海县志·艺术门》记载姚蒙善于医术,尤其精通太素脉。邹来学巡抚召他看病,姚蒙说:大人的根器有一窍渗出汗水。邹来学大惊说:这是我的隐秘疾病,你怎么知道?姚蒙说:通过脉象得知,左关脉滑而缓,是因为肝第四叶有漏孔通向下部所致。邹来学求药方。姚蒙说:不需要药,到了南京自然痊愈。用手比划说:今天是初七,大约十二日可以到。邹来学随即出发,果然在十二日早晨抵达南京后去世。预先决断死期,脉理精深的人能做到,但通过关脉的滑而缓就知道有漏孔通向下部,恐怕没有这种事。地方志书喜欢用夸张的辞藻,往往就是这样。
李东璧《奇经考》说:凡八脉不受十二正经的限制,没有表里配合,所以称为奇经。大概正经如同沟渠,奇经如同湖泽,正经的脉气隆盛,就会溢入奇经,所以秦越人将其比作天雨降下,沟渠溢满,雨水妄行,流入湖泽。按照这个说法,“奇”字应当读作奇偶的“奇”(指无表里配合)。有人读作奇正的“奇”,这是不对的。
脉象虚实之间,最难审察。叶思兰治疗一位产妇的医案中说:凡是诊脉遇到极大或极微的脉象,最宜审慎。如果脉象极大但无力,须防备阳气浮散于外。如果脉象极微,久久寻找才能摸到,在手指稍稍加力,按至骨头感觉愈坚牢的,不可认作虚寒。现在这个病症六部都没有脉,尺部之后却实数有力,这就是所谓的伏匿脉。阳气隐匿在下部,亢盛到了极点,怎么能拘泥于产后禁用寒凉的说法呢?他辨别脉象,极为精细,作为医者应当熟读并反复体会他的话。
鬼祟致病的脉象,忽大忽小,忽快忽慢。虫症的脉象,乍大乍小。这都是因为没有一定的形态。至于气郁的病症,常常因为脉道不利,迟数不调,最宜审慎考察。虚证的脉象,也有至数不齐的情况。《汪石山医案》记载一人患遗精,脉象有时浮濡而疾,有时沉弱而缓,汪石山说:脉象不恒定,是因为虚的缘故。用人参为君药,加入...(原文此处可能有缺漏,依语境推测为补气药),直到脉象出现六阴...(原文此处可能有缺漏)。亦有反关脉,诊病者均宜详审。吴郡有一位医者在当时很有名声,一位达官新娶姬妾,忽然患心病,痰涌手厥,这位医生诊察两手无脉,推辞不治疗。换医生诊脉,知道是反关脉,一剂药就好了,这位医生的名望顿时减退。
明代王文恪公震泽长语云:徐文定公担任詹事时,到苏州城,听说王时勉是明医,让他诊脉。王时勉发现公的脉有歇止,不敢直言,公说:我的脉向来有异常。王时勉说:像这样没关系。那么脉象又有歇止而非疾病的情况,临证者,能不详细考察吗?(钱塘梁氏《玉绳瞥记》说近来有人只一手有脉,一手无脉,这道理特别难以理解,这也是临证者所应当知道的。)
《汪石山医案》记载:王宜人产后因沐浴,发热呕恶,渴欲饮冷水瓜果,谵语若狂,饮食...(原文此处可能有缺漏)。体质丰浓不受补,医生用清凉药,热势加剧,汪石山诊察,六脉浮大洪数,说:产后暴损气血,孤阳外浮,内真寒而外假热,宜大补气血。给予八珍汤加炮姜八分,热势减轻大半,病患自知平时不宜服人参,不肯再服,过了一天又大热如火,再次给予前剂,暗中加入人参、...(原文此处可能有缺漏)、炮姜,连续进服二三服,热退身凉而痊愈。这段病情脉象,没有一个可以用温补的理由,医生怎能不用清凉药?等到服用清凉药而热势加剧,才知道应当用温补。然而如果不是像汪石山那样有胆识,也不能毅然使用。再者其脉虽浮大洪数,但按之必无力,与叶思兰所说的(见前文)相合,这可以从言外之意得到印证。
元和江艮庭(名声)《论语俟质》说:孔子圣德无所不通,怎么会有不懂医术的呢?从窗户握着病人的手,切其脉,既然切脉而知其病不治,所以说:亡矣,命矣。虽然他的说法未必直接涉及人道,但《礼记》疏中有夫子脉诀的说法,那么江氏的说法也自有依据。况且疾病是儿子所慎重的,难道会轻慢地交给医生而不探究其道理吗?有人说孔子既然懂医术,为什么康子送药他说“未达”(不理解/未尝试)?我说:药应当是丸散之类,不知道是什么东西,即使知道了也无法辨别其种类好坏,所以《魏书·术艺列传》记载:显祖想验证徐謇的能力,把病人放在幕帐中,让徐謇隔着切脉,深得病情兼知色候。后来高祖病重,徐謇延请医生有效,赏赐丰厚,下诏有“诚术两输,忠妙俱至”的话,他的技艺可谓精妙了。然而文昭皇太后怀世宗时,梦见被太阳追逐,化为龙环绕太后,太后醒来惊悸,遂成心疾,王显诊脉说:不是有心疾,将是怀孕生男之象。而徐謇则说是微风入脏,宜进汤药加针灸。所谓智者千虑,必有一失,医道真的不容易言说啊。
脉数时而一止为促脉,促主热,但也有因寒引起的,如伤寒脉促,手足厥逆,可灸之。注家谓其气本动,为寒所迫,则数而促也。脉缓时而一止为结脉,结主寒,但也有因热引起的,如太阳病身黄,脉沉结,少腹硬,小便利,其人如狂者,血证确凿,抵当汤主治。注家谓湿热相搏,脉缓为湿,所以里湿之脉当见沉结也。观此更加知道临证者不可专门凭借脉象了。
Kou Zongshi said: Whenever diagnosing women's diseases, one must first ask about the menstrual period upon entering. Zhang Zihe said: Whenever diagnosing gynecological diseases, one should first ask about pregnancy. He also said: When treating women's diseases, one must not lightly use herbs that break qi and move blood, for fear that the patient might be in a suspected state of pregnancy. Peng Yongxian said: Whenever diagnosing postpartum diseases, one must inquire about the amount and presence of lochia. This is the essential principle of gynecology. Shen Qianlü said: The viscera qi of infants is not yet fully developed and cannot withstand the force of medicine. Within the first year of life, unless it is a severe illness, one should not easily administer medication; treatment must be carefully considered. Even within two to three years of age, the physical form and righteous qi are essentially tender and weak; medication should not be too harsh. Harsh purgation or harsh tonification will instead cause the patient to suffer from the drugs. This is the essential principle of pediatrics. Wang Hongxu said: Carbuncle (Yong) and gangrene (Ju) are two completely different paths. Redness and swelling indicate Carbuncle, which should be treated with cooling and resolving methods; white depression indicates Gangrene, which should be treated with warming and dissipating methods. He also said: Only Ding sores (hard, deep-seated infections) can be treated with acupuncture; for all others, knives and needles should not be used lightly, and herbs that cause pain and ulceration should be prohibited. This is the essential principle of surgery.
The general outlines of the Six Channels in Shanghan Lun (Treatise on Cold Pathogenic Diseases) are largely based on inquiry. For instance, symptoms such as bitter taste in the mouth, dry throat, and vertigo in Shaoyang disease (Lesser Yang Disease), as well as alternating chills and fever, fullness and distension in the chest and hypochondrium, silence and lack of desire for food, mental irritability, and a tendency to vomit in Xiao Chai Hu Tang syndrome, are all known through inquiry. This is why Sun Simiao emphasized "inquiring before diagnosing."
The pulse of the Large Intestine is observed at the left Cun position, and the pulse of the Small Intestine is observed at the right Cun position; this is the statement in Mai Jue (Pulse Classic). Since Hua Bolin observed the pulses of the Large and Small Intestines at both Chi positions, Li Shicai praised this as a "unique insight of the ages," and later generations came to believe it. I examined Wang Shishan's Mai Jue Kan Wu (Correction of Errors in Pulse Classic), which corrects many of Wang Shuhe's statements, but did not object to the view that "the left Cun observes the Heart and Small Intestine, and the right Cun observes the Lung and Large Intestine." He stated that matching Fu organs to Zang organs, since these two meridians connect, they are observed at the same position. Additionally, Huang Kunzai (courtesy name Yuanyu) from Changyi argued that where pulse qi ascends, disease manifests above; where pulse qi descends, disease manifests below. The three Hand Yang meridians travel from the hand to the head. Although the Large and Small Intestines are located at the lowest part of the body, their pulse qi travels upward; therefore, they are observed together with the Heart and Lung at the two Cun positions. His theory is also profound and can correct the error in Hua's theory. Yang Renzhai stated that pulse qualities such as Chen Xi (Deep and Fine), Chen Chi (Deep and Slow), Chen Xiao (Deep and Small), Chen Se (Deep and Choppy), and Chen Wei (Deep and Minute) all belong to Yin; whereas Chen Hua (Deep and Slippery), Chen Shuo (Deep and Rapid), Chen Shi (Deep and Excess), and Chen Da (Deep and Large) all belong to Yang. A mistake in application could lead to death or life instantly. I believe there are exceptions. According to Ming Yi Lei An (Classified Cases of Famous Physicians) under the section on Heat Fire, Hu Xianweng treated unresolved wind-heat with both hands' pulses being Fu (Hidden). At that time, an epidemic was prevalent. Other physicians believed that a Yang syndrome presenting with Yin pulses was incurable and wanted to use Yang Du Sheng Ma Tang (Yang Toxin Ephra Twig Decoction) to raise and lift. Hu Xianweng said: This is extreme wind-heat; excessive fire causes the pulse to hide; it is not an epidemic. Raising it would cause death. He administered Lian Qiao Liang Ge San (Forsythia Cooling Chest Powder), and the condition resolved after one dose. Also, according to Mai Jue songs, if a cold injury presents with a Fu pulse in one hand, it is called Dan Fu (Single Hidden); if in both hands, it is called Shuang Fu (Double Hidden). One should not diagnose it as incurable just because a Yang syndrome shows Yin pulses. It is due to fire pathogen internal stagnation, unable to vent outward; extreme Yang resembles Yin, hence the pulse is hidden. There must be profuse sweating for resolution. Such pulses are not uncommon in epidemic conditions; practitioners should examine them carefully and not solely rely on Yang's theory.
In Zhang Zhongjing's Shanghan Lun, Jie Xiong Re Shi (Chest Binding Heat Excess) presents with a Chen Jin (Deep and Tight) pulse, pain below the heart, hardness like stone upon palpation, and is treated with Da Xian Xiong Tang (Major Expel Thorax Decoction). In Jin Gui Yao Lue (Essential Prescriptions of the Golden Cabinet), Shan Qi (Hernia) with periumbilical pain, discharge of white fluid during attacks, cold limbs, and a Chen Jin pulse is treated with Da Wu Tou Jian (Major Aconite Decoction). The same Chen Jin pulse indicates heat in one case and cold in another. Thus, how can clinicians rely solely on the pulse?
Shanghai County Annals, Art Section, records that Yao Meng was skilled in medicine, especially proficient in Tai Su Mai (Primordial Pulse diagnosis). Governor Zou Laixue summoned him to treat an illness. Yao Meng said: Your Lordship's constitution has an aperture leaking sweat. Zou Laixue was greatly surprised and said: This is my secret ailment; how do you know? Yao Meng said: I deduced it from the pulse. The Guan position on the left is Slippery and Slow; there is a leak in the fourth lobe of the Liver connecting downwards. Zou Laixue requested medicine. Yao Meng said: No medicine is needed; you will recover upon reaching Nanjing. Using his hand to estimate, he said: Today is the 7th; you should arrive around the 12th. Zou Laixue departed immediately and indeed arrived in Nanjing on the morning of the 12th, then passed away. Predicting the time of death is possible for those with profound pulse theory, but knowing of a downward leak from the Slippery and Slow Guan pulse is likely impossible. Local chronicles often use exaggerated language, and this is typical.
Li Dongbi's Qi Jing Kao (Study of Extraordinary Vessels) states: The Eight Extraordinary Vessels are not constrained by the Twelve Regular Meridians and have no exterior-interior pairing, thus they are called Extraordinary. Generally, the Regular Meridians are like ditches, and the Extraordinary Vessels are like lakes and marshes. When the pulse qi of the Regular Meridians is abundant, it overflows into the Extraordinary Vessels. Thus, Qin Yueren compared it to rain falling from the sky; when ditches overflow, water flows wildly into the lakes and marshes. According to this, the character "Qi" (Extraordinary) should be pronounced as in Qi Ou (Odd/Even) (indicating no exterior-interior pairing). Some pronounce it as in Qi Zheng (Odd/Correct), which is incorrect.
Between Deficiency and Excess pulse qualities, it is most difficult to examine accurately. Ye Silan's medical case of a postpartum woman states: Whenever encountering extremely Large or extremely Minute pulses during diagnosis, one must be most cautious. If the pulse is extremely Large but powerless, one must guard against Yang qi floating externally. If the pulse is extremely Minute, found only after prolonged searching, and feels increasingly firm when pressing to the bone with slight additional force, it should not be mistaken for Deficiency-Cold. In this case, there is no pulse in the six positions, but behind the Chi position, the pulse is Excess, Rapid, and powerful. This is what is called Fu Ni Mai (Hidden and Concealed Pulse). Yang qi is concealed below, hyperactive to the extreme. How can one stick to the prohibition of using Cold-Cooling herbs in postpartum cases? His differentiation of pulse qualities is extremely precise; practitioners should study and repeat his words.
Pulses caused by demonic influence fluctuate between large and small, rapid and slow. Pulses caused by parasites vary suddenly in size. These lack a fixed form. Regarding Qi Stagnation syndromes, often due to obstructed pulse channels, resulting in irregular speed, careful examination is essential. Deficient pulses may also have irregular rhythm. Wang Shishan Yi An (Medical Cases of Wang Shishan) records a man suffering from seminal emission, whose pulse was sometimes Floating and Soft with rapidity, and sometimes Deep and Weak with slowness. Wang said: The inconsistency of the pulse is due to deficiency. He used Ren Shen (Ginseng Root) as the chief herb... [text incomplete in source] ...until the pulse showed six Yin characteristics... [text incomplete]. There are also Fan Guan Mai (Reverse Passage Pulses); diagnosticians should examine carefully. A physician in Wu Commandery was famous at the time. A high official's newly acquired concubine suddenly suffered from Heart disease with phlegm surging and hand-Jueyin contraction. This physician diagnosed no pulse in both hands and declined treatment. Another physician diagnosed the pulse, identified it as Fan Guan Mai, and cured her with one dose. This physician's reputation dropped instantly.
Ming Dynasty Wang Wenge Gong's Zhenze Chang Yu states: When Xu Wending Gong served as Hanshi (Director of the Palace Library), he went to Suzhou City and heard that Wang Shimian was a renowned physician. He asked Wang to diagnose him. Wang Shimian noticed pauses in the Duke's pulse but dared not speak. The Duke said: My pulse has always been abnormal. Wang Shimian said: In this case, it is not concerning. Thus, there are cases of pulse pauses that are not pathological; can clinicians fail to examine carefully? (Qiantang Liang's Yusheng Pie Ji mentions someone recently who had a pulse in only one hand and none in the other; this principle is particularly hard to understand, yet it is something clinicians should know.)
Wang Shishan Yi An records: Lady Wang, after bathing postpartum, developed fever, nausea, thirst for cold water and fruits, delirium resembling madness, and loss of appetite. Her physique was robust and she could not tolerate tonification. Physicians used Cooling herbs, and the fever intensified. Wang Shishan diagnosed Floating, Large, Surging, and Rapid pulses in all six positions, stating: Postpartum sudden damage to Qi and Blood causes solitary Yang to float externally; internally true Cold, externally false Heat. It requires major tonification of Qi and Blood. He prescribed Ba Zhen Tang (Eight Treasures Decoction) with Pao Jiang (Prepared Ginger Root) 8 fen. The fever reduced by more than half. The patient knew she usually did not tolerate Ren Shen (Ginseng Root) and refused further doses. After a day, the fever returned fiercely. He gave the previous prescription again, secretly adding Ren Shen, [missing herb], and Pao Jiang. After two or three doses, the fever subsided, the body cooled, and she recovered. In this clinical presentation and pulse image, there was no reason to use Warming-Tonification initially; how could the doctor not use Cooling herbs? Only after the Cooling herbs worsened the fever did they realize Warming-Tonification was necessary. However, without Wang's courage and insight, one could not have resolutely used it. Furthermore, although the pulse was Floating, Large, Surging, and Rapid, it was powerless upon pressure, consistent with Ye Silan's statement (see above). This can be inferred beyond the explicit words.
Jiang Genting (courtesy name Sheng) of Yuanhe in Lunyu Si Zhi states: Confucius, being sage and all-knowing, could not possibly not know medicine. Holding the patient's hand through the window, he felt the pulse. Having felt the pulse and knowing the disease was incurable, he said: Perished, it is fate. Although his explanation does not directly address human affairs, the Commentary on Li Ji contains sayings of Confucius on pulse diagnosis, so Jiang's theory has its basis. Moreover, disease is something sons take seriously; how could they casually entrust it to doctors without investigating the principles? Some ask: If Confucius knew medicine, why did he say "Wei Da" (not understood/not tried) when Minister Kang offered medicine? I answer: The medicine was likely pills or powders; he did not know what it was. Even if he knew, he could not judge its quality. Thus, Wei Shu · Shu Yi Lie Zhuan records: Emperor Xianzhu wanted to test Xu Jian's abilities, placed patients in a tent, and let Xu Jian feel their pulses from outside. He grasped the disease deeply and knew the complexion signs. Later, when Emperor Xiaozu was critically ill, Xu Jian invited effective doctors and received generous rewards. An edict stated: "Sincerity and skill both delivered; loyalty and subtlety both arrived." His art was indeed exquisite. However, when Empress Dowager Wen Zhao carried Emperor Shizong, she dreamed of being chased by the sun, transforming into a dragon circling the Empress. Upon waking, she was startled and developed Heart disease. Wang Xian diagnosed the pulse and said: It is not Heart disease; it is a sign of pregnancy with a male child. But Xu Jian said it was mild wind invading the viscera and recommended decoctions and acupuncture. As the saying goes, even the wise make mistakes in a thousand deliberations; the Way of Medicine is truly not easy to discuss.
A pulse that is Rapid but stops occasionally is Cu Mai (Surging Pulse). Cu primarily indicates Heat, but it can also be caused by Cold, such as in Cold Injury where the pulse is Cu with cold limbs, treatable with moxibustion. Commentators explain that the Qi naturally moves, but forced by Cold, it becomes Rapid and Surging. A pulse that is Slow but stops occasionally is Jie Mai (Knotted Pulse). Jie primarily indicates Cold, but it can also be caused by Heat, such as in Taiyang Disease with yellow skin, Deep Knotted pulse, hard lower abdomen, free urination, and restlessness like madness; this is a definitive Blood stasis pattern, treated with Di Dang Tang (Di Dang Decoction). Commentators explain that Damp-Heat struggle makes the Slow pulse indicative of Dampness; thus, interior Dampness pulses present as Deep and Knotted. Observing this, we further know that clinicians cannot rely solely on the pulse.
