真定有一位旅客。在乙丑年六月期间，他客居他乡。因为旅途劳顿又受了湿气侵袭，导致心下部痞塞胀满，烦躁发热时发时止，躺卧不安稳。于是他在寺庙中住宿。寺中的僧人给他服用了数丸大毒药物，使他腹泻了十多次，心下痞塞的症状稍微减轻。第二天他困倦嗜睡，财物被盗贼抢劫，心中有所触动（情绪波动），随即出现燥热和口渴。他喝了一大碗冷酒。当天夜里脐部和腹部胀痛，僧人再次用之前的药让他腹泻了十多次。病情加重且危重，四肢无力，燥热身体不停抖动衣物，喜欢喝冷水，米谷食物不消化，痢疾排出物像烂鱼肠脑一样，赤白脓血混杂，完全不想吃东西，勉强进食则呕吐，痞塞比之前更严重，嗳气不止，脚部冰冷，小腹部无法忍受疼痛。他请我诊治。诊察他的脉象浮数，一息八九至，按之空虚。我追溯病源寻找根源，原来是暑天的热气已经损伤了正气，又用有毒且大热的药物攻下，一次攻下之后，所伤之物已去尽无余。但留下了巴豆的毒性，流毒于肠胃之间，导致呕吐逆乱而不能进食，这是胃气转而受伤的缘故。以及后来下脓血无度，大块肌肉陷下，皮毛枯槁，这是脾气虚弱衰退的表现。舌上红赤涩滞，口燥咽干，津液不足，这是“下多亡阴”所致。阴液既然已经亡失，心火独自旺盛，所以心胸燥热，烦乱不安。《内经》说：“独阳不生，独阴不长。”这是自然的规律。于是我辞别退下。后来换了一位医生。这位医生到来后，不审察脉象，不探究病源，只看到痞满症状，就用枳壳丸攻下。病情增添了喘促胀满，泻利不禁而死。《金匮要略》说：“不当下而强下之，令人开肠洞泄便溺不禁而死。”说的就是这种情况。圣人治病，用药有法度，不可稍有逾越。《内经》说：“大毒治病，去其六分；小毒治病，去其七分；常毒治病，去其八分；无毒治病，去其九分。如果病未尽除，再依法用谷物、肉类、水果、蔬菜来调养它。不要使治疗过度，过度就会损伤正气。”古籍记载说：“医不三世，不服其药。”这是极其谨慎的态度。那个僧人并非医者流派，妄自用大毒药物攻下太过，几天之内，使人丧命。用药失误，祸患竟然如此严重。病人选择医生，能不谨慎吗？以此为戒。
A guest from Zhending. In the sixth month of the Yichou year, while staying in another place, he contracted dampness due to fatigue and travel. He experienced epigastric fullness and stuffiness (Xin Xia Pi Man), with intermittent irritability and heat sensations, unable to sleep peacefully. He lodged in a temple. The monk administered several pills of highly toxic medicine, causing him to defecate more than ten times. The epigastric stuffiness slightly decreased. The next day, he was lethargic and sleepy. His belongings were robbed by thieves, causing emotional disturbance, which led to dryness-heat and thirst. He drank a large bowl of cold wine. That night, his umbilical and abdominal regions became distended and painful. The monk again administered the previous medicine, causing another ten-plus bowel movements. The condition worsened significantly; his limbs were weak, he felt dry-heat and trembled constantly, preferring to drink cold water. Food and grain were not digested; dysentery stools resembled rotten fish intestines and brains, mixed with red and white pus and blood. He had no appetite at all; forcing food intake caused vomiting. The stuffiness was worse than before, accompanied by incessant belching, cold feet, and unbearable pain in the lower abdomen. He asked me to treat him. I palpated his pulse: floating and rapid, beating eight or nine times per breath, empty upon pressure. I traced the origin of the disease. It seems that the heat of summer had already injured the upright Qi (Zheng Qi). Using highly toxic and hot purgatives further damaged him. After one purge, the pathogenic factors were exhausted. However, the residual toxicity of Crotonis Fructus (Badou, 巴豆) remained, spreading poison between the stomach and intestines, causing nausea and inability to eat, indicating injury to Stomach Qi. Subsequently, excessive discharge of pus and blood occurred, with sunken flesh and withered skin and hair, indicating weakness and decline of Spleen Qi. The tongue was red and rough, mouth dry, throat parched, and body fluids insufficient. This was caused by "excessive purging leading to Yin loss" (Xia Duo Wang Yin). Since Yin was lost, Heart Fire flared alone, causing dry-heat in the chest and heart, restlessness, and unease. The Classics state: "Solitary Yang does not generate, solitary Yin does not grow." This is the way of Heaven. Thus, I declined and withdrew. Later, another doctor was consulted. Upon arrival, this doctor did not examine the pulse nor investigate the source of the disease. Seeing only fullness and stuffiness, he used Zhiqiao Wan (Bitter Orange Pill) to purge. The patient developed additional wheezing and fullness, suffered from uncontrollable diarrhea, and died. The *Jingui Yaolue* states: "Purging when not indicated causes the intestines to open, leading to洞泄 (profuse watery diarrhea) and incontinence of feces and urine, resulting in death." This is exactly what happened. The sages treat diseases with methodical use of medicines, allowing no deviation. The *Neijing* states: "For highly toxic drugs, remove six-tenths of the disease; for slightly toxic drugs, remove seven-tenths; for commonly toxic drugs, remove eight-tenths; for non-toxic drugs, remove nine-tenths. If the disease is not fully resolved, repeat the method using grains, meats, fruits, and vegetables to nourish the body. Do not exceed these limits, as excess will injure the upright Qi." Records state: "If a physician has not practiced for three generations, do not take their medicine." This reflects extreme caution. That monk was not a trained physician but recklessly used highly toxic purgatives excessively. Within a few days, he caused the patient's death. The disaster caused by improper medication is thus severe. When choosing a physician, must one not be cautious? Let this serve as a warning.
