一、误吞铜钱，多食荸荠，即可化坚为软，从大便出。又方，多食胡桃自化而出。（胡
桃与铜钱共食即成粉可证。）
一、误吞铁、骨等物，肠中不能转送觉坠者，多食青菜猪油，则送入大肠，与粪同出，
甚效。
一、误吞黄金，昔江应宿治一王姓者，因事犯盐院，惊惧自吞黄金一、二钱，心中愦愦
，无
伏，计无所出，沈思银工熔金，必用硼砂，硼砂制金故也。急市硼砂四钱为末，米粥分二次
服下，少顷煎承气汤服利下，硼砂裹金从大便而出。或误服金屑未死者，用鸭血灌之可活。
一、误吞铁钉，昔张景岳先生治一王氏子，甫周岁，其母以铁钉与之玩弄，不觉纳之口
中，
甚。先生晓之曰，岂有倒悬可以出钉，而能无伤命哉。因速令抱正，遂闻啼声，乃钉已下咽
，不在喉矣。其父曰，娇嫩之脏，安能堪此。先生因其哀求之切，不能不允，故以慰之，然
计无从出，而逼索方药，顷刻再四，只得静坐斋头，潜思熟计，亦无所得。乃取本草一玩，
觊启其机，见所载云，针畏朴硝，逐悟得一方。用活磁石一钱、朴硝二钱，并研为末，付其
父，令以熬熟猪油加蜜和调药末，与之食，于申未之顷尽吞之。至次早，其父匍匐阶前曰，
昨于三鼓忽解下一物，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。乃京中钉鞋所用蘑菇钉也。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。
一、误吞铜钱，多吃荸荠，即可使坚硬的铜钱软化，随大便排出。另一方法，多吃胡桃（核桃）使其自行化出。（胡桃与铜钱同食即成粉末，可作证明。）
一、误吞铁器、骨头等物，若在肠中无法转动下行而感到下坠者，多吃青菜和猪油，则能将其送入大肠，与粪便一同排出，效果极佳。
一、误吞黄金，昔日江应宿治疗一位王姓患者，因事触犯盐政官员，惊恐之下自吞一两钱黄金，心中烦闷昏乱，心神不宁，无计可施。他沉思银匠熔金必用硼砂，是因为硼砂能熔化黄金。于是急忙购买四钱硼砂研为细末，分两次用米粥送服。不久后煎服承气汤以通利大便，硼砂包裹着黄金从大便排出。若是误服金屑但未死亡者，灌服鸭血即可救活。
一、误吞铁钉，昔日张景岳先生治疗一位王氏之子，刚满周岁，其母给铁钉让他玩耍，不慎吞入口中，情况危急。先生告知家属说，难道有倒悬取钉而不伤性命的方法吗？于是迅速让人将孩子抱正，随即听到啼哭声，说明钉子已咽下，不在咽喉处了。孩子的父亲说，娇嫩的内脏，怎能承受此物。先生因其哀求恳切，不忍拒绝，便加以安慰，但苦于无计可施，而家属又急切索要药方，片刻间反复催促，只得静坐书房，深思熟虑，也无结果。于是拿起《本草纲目》翻阅，希望从中获得启发，见书中记载：“针畏朴硝”，顿时领悟得一法。使用活磁石一钱、朴硝二钱，共同研为细末，交给其父，令其用熬熟的猪油加蜂蜜调和药末，喂给孩子吃，在申时到未时之间全部吞服。到了第二天早上，其父跪爬在台阶前说，昨天半夜忽然排出一物，大如芋头，晶莹如白菜，润滑无棱角，药物包裹在外面，拨开查看，则钉子在其中了。乃是京城制鞋所用的蘑菇钉。大概硝石非借助磁石不能使药物附着于钉上，磁石非借助硝石不能迅速驱逐钉子排出，不用油则无以润滑，不用蜜则未必能吞咽。综合这四种物质，着着的附着，逐者的驱赶，润者的润滑，协同功效合力，包裹保护而出。
I. If a copper coin is accidentally swallowed, consuming many water chestnuts (Dioscorea esculenta) can soften the hard object, allowing it to be passed out through the stool. Another method involves consuming many walnuts (Juglans regia) to facilitate its natural dissolution and expulsion. (The fact that walnuts and copper coins become powder when eaten together serves as evidence.)
II. If ironware, bones, or similar objects are accidentally swallowed and cause a sensation of heaviness or dropping in the intestines because they cannot move downward, consuming plenty of green vegetables and lard (pig fat) can help push them into the large intestine for elimination with feces, which is highly effective.
III. Regarding the accidental swallowing of gold: In the past, Jiang Yingsu treated a patient surnamed Wang who, due to fear after offending the salt administration official, swallowed one or two qian of gold. The patient suffered from mental confusion and restlessness, with no solution in sight. Recalling that silversmiths use borax (Borax) to melt gold, he hastily purchased four qian of borax, ground it into powder, and took it in two doses mixed with rice gruel. Shortly thereafter, Chengqi Tang (Cassia Decoction) was decocted and administered to induce purgation. The borax wrapped around the gold, and it was expelled through the stool. For those who have accidentally ingested gold dust but are not yet dead, administering duck blood can save their lives.
IV. Regarding the accidental swallowing of an iron nail: Mr. Zhang Jingyue once treated the son of a family surnamed Wang, who was just one year old. His mother gave him an iron nail to play with, and he inadvertently swallowed it, creating a critical situation. Mr. Zhang informed the family, "Is there any way to retrieve a suspended nail without endangering life?" He then instructed them to hold the child upright. A cry was heard, indicating the nail had passed the throat and entered the esophagus/stomach. The father said, "How can such delicate internal organs withstand this?" Moved by the father's desperate pleas, Mr. Zhang comforted him but, lacking an immediate solution despite repeated urgent requests for a prescription, sat quietly in his study to think deeply. Still finding no answer, he picked up the Bencao (Materia Medica) to seek inspiration. He noticed the entry stating, "Needles are feared by Mirabilite." This suddenly inspired a formula. He used one qian of active lodestone (Magnetitum) and two qian of mirabilite (Natrii Sulfas), grinding them together into a fine powder. He gave this to the father, instructing him to mix the powder with boiled lard and honey, and feed it to the child, ensuring complete ingestion between 3 PM and 5 PM (Shen-Wei hours). The next morning, the father crawled before the steps saying, "Yesterday at midnight, I passed an object about the size of a taro root, crystal clear like cabbage, smooth and lubricated without sharp edges. The medicine coated the outside; upon inspection, the nail was inside. It was a mushroom-headed nail used in shoe-making in the capital." Essentially, mirabilite alone cannot make the medicine adhere to the nail, nor can lodestone alone rapidly expel the nail. Without oil, there is no lubrication; without honey, swallowing may be difficult. Combining these four elements allows the adhering agent to stick, the expelling agent to drive, and the lubricant to ease passage, working synergistically to wrap and expel the foreign body.
