不堪望，奚以方。
军吏梅平，因得疾除名，还家。家居广陵，未至二百里，止亲人舍，其曰先生适至主人
许，主人令先生视之。先生一望见，即谓平曰∶“君早见我，可不至此，今疾已结，不可为，
趣
按∶凡人内有病，必先后于外，故医以望为第一要义。扁鹊之著名，即在于能望也，先
生望平色，知其必死，虽有所本，亦由能决。今之医士，不解斯义，徒恃切脉，以作指针。
故病者将死，犹为定方。吾见亦多矣。噫！（孙思邈注）
胆若寒，效难见。
昔汉郭玉尝言∶“贵者处尊高以临臣，臣怀怖慑以承之。其为疗也，有四难焉。自用意
而不任臣，一难也；将身不谨，二难也；骨节不强，不能使药，三难也；好逸恶劳，四难也。
针有分寸，时有破漏，重以恐惧之心，加以裁慎之志，臣意犹且不尽，何有于病哉。此其所
以不愈也。”不知先生所得之医经中，已有此言，故先生治曹操头风未除。操曰∶“佗能愈。
此小人养吾病，欲以自重，然吾不杀此子，终当不为吾断此根原耳。”操之为是言，殆即郭
氏所谓∶“贵者处尊高以临臣”之意也。先生之不能根治，即医经所载二语尽之矣。（孙思
邈注）
黑血聚，盛怒愈。
按∶血郁于上焦，非可剖而出之，惟盛怒则肝之鼓动力足，郁自散。上行则吐，势所必
然。先生尝本此以治郡守病，以为使之盛怒则瘥，乃多受其货而不加功。无何，弃去，又遗
书辱詈之。郡守果大怒，令人追杀之，不及。因 恚，吐黑血数升而愈。（孙思邈注）
难以救治，用什么方剂呢？
军吏梅平，因为患病被免职，回家。家住广陵，离家不到二百里，住在亲戚家。那天先生刚好来到主人那里，主人让先生给梅平看病。先生一眼看见，就对梅平说：“你早点来见我，不至于到这个地步，现在病邪已经凝结，无法医治了，快离开吧。”
按语：大凡人体内有病，必然先反映于外表，所以医生把望诊作为第一要义。扁鹊之所以著名，就在于他能通过望诊诊断疾病。先生观察梅平的气色，知道其必死无疑，这虽然有所依据，但也源于他能够决断。现在的医生，不理解这一道理，仅仅依靠切脉，把它当作治疗的指针。所以病人即将死亡时，还在开方子。我见到的这种情况很多了。唉！（孙思邈注）
胆气若寒，疗效很难显现。
从前汉代郭玉曾经说：“地位尊贵的人处于高位俯视臣下，臣下怀着恐惧畏惧的心情去承接侍奉。为他们治疗，有四个难点。自以为是而不信任臣下，这是第一个难点；自身生活不谨慎，这是第二个难点；骨节不强健，不能配合用药，这是第三个难点；喜好安逸厌恶劳动，这是第四个难点。针刺有分寸，时间上有疏漏，再加上恐惧的心理，加上谨慎的态度，即使是名医仓公尚且不能完全治愈，何况是普通的病人呢。这就是他们不能痊愈的原因。”不知道先生所掌握的医经中，是否已有此言，所以先生治疗曹操的头风病未能除根。曹操说：“华佗能治好我的病。这个小人想借此抬高自己的身价，然而我不杀这个人，终究不会让他为我断绝这个病根。”曹操说这番话，大概也就是郭氏所说的“地位尊贵的人处于高位俯视臣下”的意思。先生不能根治，就是医经所载的那两句话概括尽了。（孙思邈注）
黑血积聚，盛怒后痊愈。
按语：血液郁结在上焦，不可能剖开取出，只有盛怒时肝气的鼓动力量充足，郁结自然消散。气血上行则呕吐，这是势所必然的。先生曾经根据这一原理治疗郡守的病，认为使他盛怒就能痊愈，于是收受了郡守很多财物却不加治疗。没过多久，就抛弃离去，又写信辱骂他。郡守果然大怒，派人追杀华佗，没追上。郡守因此愤怒，吐出几升黑血而痊愈。（孙思邈注）
Difficult to treat; what prescription can be used?
Mei Ping, a military official, was dismissed due to illness and returned home. His residence was in Guangling. Before traveling two hundred li, he stopped at a relative's house. On that day, the Master happened to arrive at the host's place. The host asked the Master to examine Mei Ping. Upon seeing him, the Master immediately said to Mei Ping: "If you had seen me earlier, you would not have reached this state. Now the pathogenic factor has consolidated, and it cannot be treated. Leave quickly."
Note: Generally, when there is an internal disease, it must manifest externally first. Therefore, physicians consider observation (Wang Zhen) as the primary principle. Bian Que became famous precisely because of his ability to observe. By observing Mei Ping's complexion, the Master knew he would surely die. Although this was based on evidence, it also stemmed from his ability to make decisive judgments. Physicians today do not understand this principle; they rely solely on pulse diagnosis (Qie Mai) as their guide. Thus, even when a patient is near death, they are still prescribing formulas. I have witnessed this situation many times. Alas! (Commentary by Sun Simiao)
If the Gallbladder Qi is cold, therapeutic effects are hard to manifest.
In the past, Guo Yu of the Han Dynasty once said: "Noble persons occupy high positions and look down upon ministers; ministers receive them with fear and trepidation. Treating them presents four difficulties. Being self-willed and not trusting ministers is the first difficulty; being careless with one's body is the second difficulty; having weak joints and being unable to facilitate medication administration is the third difficulty; loving ease and hating labor is the fourth difficulty. Acupuncture has its specific points and timing may have omissions. With a fearful heart and cautious will, even the expert physician Cang Gong could not guarantee complete cure, let alone ordinary patients. This is why they do not recover." It is unknown whether the medical classics possessed by the Master contained these words, which explains why the Master failed to completely cure Cao Cao's Head Wind (Tou Feng). Cao Cao said: "Hua Tuo could cure my illness. This villain cultivates my illness to elevate himself. However, if I do not kill this man, he will ultimately not cut off the root of my disease." Cao Cao's statement likely reflects the meaning of Guo's words: "Noble persons occupy high positions and look down upon ministers." The Master's inability to achieve a radical cure was fully explained by the two sentences recorded in the medical classics. (Commentary by Sun Simiao)
Accumulation of black blood; recovery through intense anger.
Note: Blood stagnation in the Upper Jiao cannot be removed by incision. Only when intense anger occurs does the Liver's driving force become sufficient, causing the stagnation to dissipate naturally. As the qi and blood move upward, vomiting is inevitable. The Master once applied this principle to treat the Prefect's illness. He believed that inducing intense anger would lead to recovery. Therefore, he accepted much of the Prefect's wealth but provided no treatment. Soon after, he left abruptly and sent a letter insulting the Prefect. The Prefect indeed became furious, ordered men to chase and kill Hua Tuo, but failed to catch him. Out of resentment, the Prefect vomited several sheng of black blood and recovered.
