一、来宅女人，年近三旬，因患虚损，更兼喉癣疼痛，多医罔效。余诊其脉，则数而无
力。察其证，则大便溏泄。问其治，则皆退热清火之剂。然愈清火而喉愈痛。察之既确，知
其本非实火，而且多用寒凉，以致肚腹不实，总亦格阳之类也。遂专用理阴煎及大补元煎之
类出入间用，不半月而喉痛减，不半年而病全愈。
一、王氏子，甫周岁，其母以一铁钉与之玩弄，不觉纳之口中，吞入喉间，其父号呼求
救。余往视之，但见其母倒提儿足，以冀其出，口鼻皆血，危剧之甚。余晓之曰∶岂有倒悬
可以出钉而能无伤命者哉？因速令抱正，遂闻啼声。余曰∶钉已下咽，不在喉矣。其父曰∶
娇嫩之脏，安能堪此？但因其哀求之切，不得不允，姑以慰之，然计无从出，而逼索方药，
顷刻数四。余只得静坐斋头，潜思熟计，亦无所得，乃取本草一玩，觊启其几。见所载曰∶
铁畏朴硝。遂得一计，乃用活磁石一钱，朴硝二钱，并研为末，付其父。令以熬熟猪肉加蜜
和调药末与之，于申末之顷尽吞之。至次早，其父匍匐阶前曰∶昨于三鼓时，忽解下一物，
大如芋子，莹如 菜，润滑无棱，药护其外，拨而视之，则钉在其中矣。持以视余，乃京中
钉鞋所用蘑菇钉也。其父索其方，并问其故。余曰∶所用者，芒硝、磁石耳。盖硝非磁石不
能使药附钉，磁石非硝不能逐钉速出，非油则无以润，非蜜则未必吞。合是四者，则着者着
，逐者逐，润者润，同功合力，裹护而出矣。公亦以为然否？其父手额称谢曰∶神哉！不可泯
也，宜笔记之，以资后人之识焉。
一、来宅的女主人，年龄接近三十岁，因为患有虚损病，又兼有喉癣引起的疼痛，多位医生治疗都没有效果。我诊察她的脉象，发现脉搏快而无力。观察她的症状，发现大便稀溏泄泻。询问之前的治疗方法，都是使用退热清火的药剂。然而越是清火，喉咙的疼痛反而越严重。经过详细检查确认，知道她根本就不是实火，而且由于过多使用寒凉药物，导致腹部脾胃虚弱不实，这总属于格阳证（真寒假热）一类。于是专门交替使用理阴煎和大补元煎等方剂，不到半个月喉咙痛减轻，不到半年疾病完全痊愈。
二、王家的儿子，刚满周岁，他的母亲拿一枚铁钉给他玩耍，孩子不知不觉吞入口中，卡在咽喉之间，父亲大声呼救。我去查看时，只见母亲倒提着孩子的双脚，希望钉子能掉出来，结果口鼻都出血了，情况非常危急。我劝告他们说：哪有倒悬着就能让钉子出来而不伤及性命的道理呢？于是急忙让人把孩子抱正，随即听到孩子的哭声。我说：钉子已经咽下去了，不在喉咙里了。父亲说：孩子脏腑娇嫩，怎么能承受这种伤害呢？只是因为他哀求得急切，不得不答应姑且安慰他一下，然而实在想不出办法，逼问药方，一会儿就问好几次。我只得安静地坐在书房里，深思熟虑，也没有想出办法，于是拿起《本草纲目》翻阅，希望能从中得到启发。看到书上记载：铁畏朴硝（芒硝）。于是想到一个计策，便取活磁石一钱，朴硝二钱，一起研成粉末，交给孩子的父亲。让他用煮熟的猪肉加蜂蜜调和药粉给孩子吃，在申时末刻全部吞服。到了第二天早上，父亲爬在台阶前说：昨天半夜三更时，忽然排出一物，大小像芋头，晶莹像白菜，光滑没有棱角，外面包裹着药物，拨开一看，钉子就在其中。拿着给我看，原来是北京城里钉鞋用的蘑菇钉。父亲索要药方，并询问其中的原理。我说：所用的是芒硝和磁石罢了。大概是因为硝石没有磁石就不能使药物附着在钉子上，磁石没有硝石就不能迅速将钉子排出，不用油就没有润滑作用，不用蜂蜜就不一定能吞下。结合这四者，粘着的粘着，驱逐的驱逐，润滑的润滑，协同功效合力，包裹保护着排出来了。您也认为这样吗？父亲抚额致谢说：真是神妙啊！不能埋没它，应该记录下来，以供给后人认识参考。
1. The female owner of the Lai residence, nearing thirty years of age, suffered from *Xu Sun* (Deficiency and Damage) complicated by pain due to *Hou Xuan* (Throat Lichen/Atrophic Pharyngitis), with no effect from multiple physicians. Upon examining her pulse, I found it rapid yet forceless (*Shu Er Wu Li*). Observing her symptoms, I noted loose stools and diarrhea (*Da Bian Tang Xie*). Inquiring about previous treatments, I learned they had all used heat-clearing and fire-purging prescriptions. However, the more the fire was cleared, the worse the throat pain became. After thorough examination and confirmation, I determined that this was not excess fire (*Shi Huo*), but rather a condition caused by excessive use of cold and cool herbs, leading to abdominal deficiency and coldness, which falls under the category of *Ge Yang* syndrome (True Cold, False Heat). Consequently, I exclusively alternated between *Li Yin Jian* (Reasoning Yin Decoction) and *Da Bu Yuan Jian* (Great Tonification of the Source Decoction). Within half a month, the throat pain subsided; within half a year, the disease was completely cured.
2. The son of the Wang family, just one year old, was playing with an iron nail provided by his mother and accidentally swallowed it into his throat. His father cried out for help in distress. Upon my arrival, I saw the mother holding the child upside down by the feet, hoping the nail would fall out, resulting in bleeding from the mouth and nose, a critically dangerous situation. I advised them, "Is there any way to extract the nail by suspending the child upside down without endangering their life?" I immediately instructed someone to hold the child upright, after which the child began to cry. I stated, "The nail has already passed the pharynx and is in the esophagus/stomach." The father replied, "How can such delicate internal organs withstand this?" Due to his desperate pleading, I reluctantly agreed to try something merely to comfort him, though I had no immediate solution. He repeatedly demanded a prescription in a short time. I sat quietly in my study, thinking deeply, but found no answer. I then picked up the *Ben Cao* (Materia Medica) to read, hoping for inspiration. I saw the entry stating: "Iron fears *Pu Xiao* (Mirabilite)." This gave me an idea. I took one qian of living lodestone (*Ci Shi*) and two qian of *Pu Xiao* (Mirabilite/Glauber's Salt), ground them into powder, and gave it to the father. I instructed him to mix the powder with boiled pork and honey, and have the child swallow it entirely towards the end of the Shen hour (3-5 PM). The next morning, the father crawled before the steps and said, "Yesterday around midnight, I suddenly passed a object, as large as a taro root, clear like cabbage, smooth and edgeless, coated externally by the medicine. Upon inspection, the nail was inside." He showed it to me; it was a mushroom-headed nail used for shoe-making in Beijing. The father asked for the prescription and its rationale. I explained, "I used Mirabilite and Lodestone. Essentially, without Lodestone, Mirabilite cannot make the medicine adhere to the nail; without Mirabilite, Lodestone cannot rapidly expel the nail. Without oil/fat, there is no lubrication; without honey, swallowing might be difficult. Combining these four elements, the adhering agent adheres, the expelling agent expels, the lubricant lubricates, working synergistically to wrap and protect the nail during expulsion." Do you agree? The father bowed and thanked me, saying, "Truly miraculous! It must not be forgotten. It should be recorded to aid future generations' understanding."
