虚者补之,实者泻之,虽三尺之童,皆知之矣。至于五实五虚,岂可以泛泛虚实
用药哉?《内经》明言其状,如俗工不识何?此二证所以见杀于委靡之手也。坐视人之死,
犹相夸曰∶“吾药稳。”以诳病家。天下士大夫亦诚以为然,以诳天下后世,岂不怪哉!夫一身犹一
国也。如寻邑百万围昆阳,此五实证也,故萧王亲犯中原而笃战。如河内饥,而又经火灾,此
五虚证也,故汲黯不避矫诏而发仓。此可与达权知变者论,不可与贪常嗜琐者说也。
故曰∶庸人误天下,庸工误病患,正一理也。
《内经》曰∶五实者死,五虚者亦死。夫五实
者,谓五脏皆实也;五虚者,谓五脏皆虚也。腑病为阳,易治而鲜死;脏病为阴,难治而多死。
《经》明言∶脉盛,皮热,腹胀,前后不通,闷瞀者,五实也。脉盛为心,皮热为肺,腹胀
为脾,前后不通为肾,闷瞀为肝,五脏皆实之证也。五虚者反是∶脉细,皮寒,气少,泻利前后,
饮食不入者,五虚也。脉细为心,皮寒为肺,气少为肝,泄利前后为肾,饮食不入为脾,此
五脏皆虚之证也。夫五实为五脏俱太过,五虚为五脏俱不及。《内经》言此二证皆死,非谓
必死也,谓不救则死,救之不得其道,亦死也。其下复言∶将粥入胃则虚者活,身汗后利则实者
活,此两证自是前二证之治法也。后人不知是治法,只作辨验生死之断句,直谓病患有此则生
,无此则死。虚者听其浆粥自入胃,实者听其自汗自利,便委之死地,岂不谬哉?夫浆粥入
胃而不注泄,则胃气和,胃气和则五虚皆实也,是以生也;汗以泄其表,利以泄其里,并泄
则上下通,上下通则五实皆启矣,是以生也。此二证异常,却不宜用。班氏所谓有病不服药
之言,盖其病大且笃故也。
余向日从军于江淮之上。一舟子病,予诊之,乃五实也。余自幼
读医经,尝记此五实之证,竟未之遇也。既见其人,窃私料之,此不可以常法治,乃可大作
剂而下之。殊不动摇,计竭智穷,无如之何。忽忆桃花萼丸,顿下七、八十丸,连泻二百余
行,与前药相兼而下,其人昏困,数日方已。盖大疾之已去,自然卧憩,不如此,则病气无
由衰也。徐以调和胃气之药, 粥日加,自尔平复。
又尝过鸣鹿邸中,闻有人呻吟声息,瘦削痿然无力。余视之,乃五虚也,余急以圣散子,二服
作一服。此证非三钱、二钱可塞也。续以胃风汤、五苓散等药,各大作剂,使顿服,注泻方
止,而浆粥入胃,不数日,而其人起矣。
故五虚之受,不加峻塞,不可得而实也。彼庸工治
此二证,草草补泻,如一杯水,救一车薪之火也,竟无成功,反曰∶虚者不可补,实者不可
泻。此何语也?吁!不虚者强补,不实者强攻,此自是庸工不识虚实之罪也。岂有虚者不
可补,实者不可泄之理哉?予他日又思之∶五实证,汗、下、吐三法俱行更快;五虚证,一
补足矣!今人见五实证,犹有塞之者,见五虚证,虽补之而非其药。本当生者,反钝滞迁延
,竟至于死耳!夫圣散子有干姜,寻常泻利勿用,各有标本;胃风、五苓有桂,所以温经散
表,而分水道。圣散子之涩燥,胃风、五苓之能分,皆辛热辛温之剂也,俗工往往聚讪,以予
好用寒凉,然予岂不用温补?但不遇可用之证也。
谤喙。咸欲夸己以标名,从谁断之?悲夫!
凡是虚证就用补法,实证就用泻法,即使是几岁的孩童也知道这个道理。至于五实和五虚这两种病证,怎么能用一般的虚实理论来随意用药呢?《黄帝内经》明确描述了它们的症状,但世俗的医生却不认识,这就是为什么这些病人往往死在那些萎靡不振、医术低劣的医生手中的原因。看着别人死去,他们却互相夸耀说:“我的药很稳妥。”以此来欺骗病人家属。天下的士大夫也真的认为这是对的,从而欺骗天下和后世的医者,这难道不奇怪吗!
人体就像一个国家一样。比如王寻率领百万大军包围昆阳城,这就是五实证的表现,所以萧王(刘秀)亲自率军深入中原进行殊死搏斗。又比如河内地区发生饥荒,又遭受火灾,这就是五虚证的表现,所以汲黯不顾假传圣旨的风险而打开粮仓赈济灾民。这种权变之道只能与通达事理、懂得变化的人讨论,不能与那些墨守成规、拘泥于琐碎细节的人说。
所以说:平庸的人误了天下,平庸的医生误了病患,道理是一样的。
《黄帝内经》说:出现五实证的会死,出现五虚证的也会死。所谓五实,是指五脏都处于实证状态;所谓五虚,是指五脏都处于虚证状态。腑病属于阳,容易治疗且很少死亡;脏病属于阴,难以治疗且多导致死亡。
《内经》明确指出:脉象盛大,皮肤发热,腹部胀满,大小便不通,胸闷昏厥,这是五实证。脉盛对应心,皮热对应肺,腹胀对应脾,前后不通(大小便闭)对应肾,闷瞀(胸闷昏厥)对应肝,这是五脏皆实的证候。五虚证则相反:脉象细弱,皮肤发冷,气短少息,大小便泄利不止,饮食无法入口,这是五虚证。脉细对应心,皮寒对应肺,气少对应肝,泄利前后对应肾,饮食不入对应脾,这是五脏皆虚的证候。
所谓五实,是五脏功能都太过亢盛;五虚,是五脏功能都极度不足。《内经》说这两种证候都会死,并不是说必然死亡,而是说如果不救治就会死,如果救治不得当方法,也会死。经文接着说:“如果粥食进入胃中,虚证患者就能活;如果身体出汗且大便通畅,实证患者就能活。”这两句话实际上是针对前两种证候的治疗方法。后人不知道这是治法,只把它当作判断生死的断语,直接认为病人有这些表现就生,没有就死。让虚证病人听任浆粥自行入胃,让实证病人听任其自汗自利,这就等于把病人推向死地,这难道不是谬误吗?
如果浆粥进入胃中且不发生泄泻,那么胃气调和,胃气调和则五虚转化为实,所以能活;通过发汗解除表邪,通过通利解除里滞,表里双解则上下通畅,上下通畅则五实得以开启,所以能活。这两种证候病情异常严重,此时不宜使用常规药物。班固所说的“有病不服药”的话,是因为病情重大且危急的缘故。
我当年随军在江淮一带时,有一位船夫生病,我诊察后,发现是五实证。我自幼读医书,曾记得这五实证的描述,但从未遇到过。见到这个人后,我私下推测,此病不能用常法治,必须大剂量使用攻下法。起初用药后病情毫无动摇,我想尽了办法也无计可施。忽然想起桃花萼丸,立刻让他服下七八十丸,结果连续腹泻二百多次,与前服的药物一起排出体外,病人陷入昏沉困倦的状态,几天后才恢复。因为大病邪气去除,自然需要卧床休息,如果不这样,病气就无法衰退。随后我用调和胃气的药物,逐渐增加米粥的摄入,病人就这样平复了。
我又曾经过鸣鹿驿站,听到有人呻吟声息,身体消瘦痿软无力。我看他,发现是五虚证,我急忙使用圣散子,将两服药量合并为一服煎煮。这种证候不是三钱、二钱的小剂量可以应付的。随后再用胃风汤、五苓散等药物,也都大剂量煎煮,让病人一次性服用,直到停止泄泻,浆粥能够进入胃中,没过几天,病人就起来了。
所以,对于五虚证的受邪,如果不采用峻猛的补益固涩之法,是不可能使其转为实证的。那些庸医治疗这两种证候,草草地补泻,就像用一杯水去救一车柴的火一样,最终没有成功,反而说:“虚证不可补,实证不可泻。”这是什么话呢?唉!不虚的人强行进补,不实的人强行攻伐,这完全是庸医不识虚实之罪的体现。哪里有虚证不可补、实证不可泻的道理呢?
我后来又想:五实证,汗法、下法、吐法同时运用见效更快;五虚证,只要补足正气即可!现在的人见到五实证,还有堵塞治疗的;见到五虚证,虽然补益但不是对症的药。本来能活的病人,反而因迟钝停滞、拖延迁延,最终导致死亡!圣散子中含有干姜,通常用于止泻痢,各有标本侧重;胃风汤、五苓散中含有桂枝,用来温经散表,分利水道。圣散子的涩燥,胃风汤、五苓散的分利作用,都是辛热或辛温的方剂。世俗的医生往往聚在一起讥讽我,说我好用寒凉药,然而我难道不用温补药吗?只是没有遇到适合用的证候罢了。
诽谤之声四起,大家都想夸耀自己以标榜名声,这该由谁来评判呢?可悲啊!
For deficiency syndromes, apply tonification; for excess syndromes, apply purgation. Even a child of three years old knows this. But what about the Five Excess (Wu Shi) and Five Deficiency (Wu Xu) syndromes? How can one casually prescribe medication based on general concepts of excess and deficiency? The *Huangdi Neijing* (Yellow Emperor's Inner Canon) clearly describes their manifestations, yet ordinary physicians fail to recognize them. This is why patients often die at the hands of incompetent doctors who are lethargic and inept. Watching others die while boasting, "My medication is stable," thereby deceiving the patient's family, is common. Scholars throughout the world also genuinely believe this, thereby deceiving future generations. Is this not strange?
The human body is like a state. For instance, when Wang Xun led a million troops to besiege Kunyang, this represented an **Five Excess** syndrome; thus, Prince Xiao (Liu Xiu) personally ventured into the central plains to fight a decisive battle. Conversely, when Henei suffered famine compounded by fire, this represented a **Five Deficiency** syndrome; thus, Ji An disregarded the risk of forging imperial edicts to open granaries for relief. Such principles of adapting to changing circumstances can only be discussed with those who understand flexibility, not with those who cling to convention and trivialities.
Therefore, it is said: Mediocre people mislead the world, and mediocre physicians mislead patients; the principle is the same.
The *Huangdi Neijing* states: Those presenting with Five Excess will die; those presenting with Five Deficiency will also die. "Five Excess" refers to all five Zang organs being in an excess state; "Five Deficiency" refers to all five Zang organs being in a deficiency state. Fu organ diseases belong to Yang, are easier to treat, and rarely result in death; Zang organ diseases belong to Yin, are difficult to treat, and frequently result in death.
The Classic explicitly states: A surging pulse, hot skin, abdominal distension, obstruction of urination and defecation, and chest oppression with dizziness constitute the Five Excess syndrome. A surging pulse corresponds to the Heart; hot skin corresponds to the Lung; abdominal distension corresponds to the Spleen; obstruction of urination and defecation corresponds to the Kidney; chest oppression and dizziness correspond to the Liver. These are signs that all five Zang organs are in excess. The Five Deficiency syndrome is the opposite: a fine pulse, cold skin, shortness of breath, uncontrolled diarrhea and urinary incontinence, and inability to eat or drink. A fine pulse corresponds to the Heart; cold skin corresponds to the Lung; shortness of breath corresponds to the Liver; uncontrolled diarrhea and urinary incontinence correspond to the Kidney; inability to eat corresponds to the Spleen. These are signs that all five Zang organs are deficient.
Five Excess means the five Zang organs are excessively hyperactive; Five Deficiency means they are profoundly inadequate. When the *Neijing* says these two syndromes lead to death, it does not mean death is inevitable, but rather that without treatment, death occurs, and even with treatment, improper methods also lead to death. The text further states: "If porridge enters the stomach, the deficient patient lives; if sweat appears and bowels move, the excess patient lives." These two statements are actually therapeutic methods for the aforementioned syndromes. Later generations misunderstood these as diagnostic criteria for life and death, believing that presence of these signs indicates survival and absence indicates death. Allowing a deficient patient to wait for porridge to enter the stomach naturally, and allowing an excess patient to wait for spontaneous sweating and bowel movements, is equivalent to sending them to their death. Is this not absurd?
If porridge enters the stomach without causing diarrhea, the Stomach Qi harmonizes. When Stomach Qi harmonizes, the Five Deficiency transforms into excess, leading to survival. Sweating resolves the exterior, and purgation resolves the interior. Simultaneous resolution allows communication between the upper and lower jiao. When upper and lower communicate, the Five Excess is opened, leading to survival. These two syndromes are exceptional and severe; routine medications are inappropriate. The statement by Ban Gu regarding "not taking medicine when ill" applies because the disease is major and critical.
In my past military service along the Jianghuai region, a boatman fell ill. Upon diagnosis, I identified it as a Five Excess syndrome. Having studied medical classics since childhood, I recalled the description of this syndrome but had never encountered it clinically. Observing the patient, I privately deduced that conventional therapy would fail; instead, a large dose of purgatives was required. Initial treatments failed to move the condition. Exhausted of ideas, I suddenly remembered Taohua E Wan (Peach Blossom Calyx Pill). I administered 70–80 pills immediately. The patient experienced over 200 episodes of diarrhea, expelling both the new and previous medications. He fell into a coma-like stupor, recovering after several days. This was necessary because removing a major pathogen requires natural rest; otherwise, the pathogenic qi cannot subside. Subsequently, I used herbs to harmonize Stomach Qi, gradually increasing his intake of rice gruel, and he recovered.
Once passing through the Mingu Post Station, I heard groaning from someone who was emaciated, flaccid, and weak. Upon examination, I diagnosed a Five Deficiency syndrome. I urgently prescribed Sheng San Zi (Holy Powder), combining two doses into one preparation. This syndrome cannot be treated with small doses of 3 qian or 2 qian. I then followed up with Wei Feng Tang (Stomach Wind Decoction) and Wu Ling San (Five-Ingredient Powder with Poria), administering large doses at once. Diarrhea ceased, porridge entered the stomach, and within a few days, the patient rose and recovered.
Therefore, for Five Deficiency syndromes, unless strong astringent and tonifying measures are taken, recovery is impossible. Mediocre physicians treat these syndromes with casual tonification or purgation, akin to using a cup of water to extinguish a cartload of burning firewood. They achieve no success yet claim, "Deficiency cannot be tonified, excess cannot be purged." What nonsense! It is the fault of incompetent physicians who do not understand excess and deficiency that they force tonification on non-deficient cases and force purgation on non-excess cases. How can there be a principle that deficiency cannot be tonified or excess cannot be purged?
I later reflected: For Five Excess syndromes, employing sweating, purgation, and vomiting methods simultaneously yields faster results; for Five Deficiency syndromes, simple tonification suffices! Yet today, some physicians still obstruct treatment for Five Excess, and for Five Deficiency, they use incorrect tonifying herbs. Patients who should survive instead suffer from sluggishness and delay, ultimately dying. Sheng San Zi contains Gan Jiang (Dried Ginger), typically used for diarrhea, addressing specific indications. Wei Feng Tang and Wu Ling San contain Gui Zhi (Cinnamon Twig), which warms meridians, disperses the exterior, and separates fluids. Sheng San Zi’s astringency and dryness, and the fluid-separating ability of Wei Feng Tang and Wu Ling San, are all acrid-hot or acrid-warm formulas. Vulgar physicians often gather to slander me, claiming I favor cold-cooling herbs. Do I not use warm-tonifying herbs? I simply do not encounter suitable cases for them.
Slander abounds; everyone seeks to boast and gain fame. Who shall judge this? Alas!
