苏州府通判仰同知（名璇）喜欢研读医书，每当家人生病就自行调理。他的姐姐在六月间因劳累倦怠而中暑，自行服用六和汤、香薷饮之类的药物，结果反而导致虚火上升，出现面红、身热的症状。后来邀请刘宗序诊视，发现六脉疾速且数，三部脉象豁大而无力。刘宗序说：“此病起初是因为中气不足，内伤生冷瓜果及未煮熟的食物，导致体内虚弱发热，这不是六和汤、香薷饮所能治疗的。况且夏季月份，伏阴之气潜伏在内，若再用重寒之药与之相合，这就成了阴盛格阳的病症。急需使用补中益气汤，加入三钱附子、一钱煨干姜共同煎煮，然后将药液置于冰中浸冷后服用。”当夜患者熟睡，直到天明微微出汗而痊愈。仰同知拜谢道：“关于‘伏阴’的说法我已经领教了，但不明白为什么要用冰来冷却药物。”刘宗序说：“这正是《内经》中‘热因寒用’、‘寒因热用’的道理，有什么难理解的？”仰同知大为叹服。
宋朝的蔡元长深受大便秘结之苦，国医们用药都无法使其通利，大概是因为蔡元长不肯服用大黄的缘故。当时史载之还未出名，前去拜见，守门人刁难许久才得以相见。诊脉之后，史载之想要出奇制胜，便请求二十文钱。蔡元长问做什么用，史载之说想买紫菀。于是史载之将紫菀研成末让他服下，不一会儿大便就通了。蔡元长感到惊异，询问原因。史载之说：“大肠是肺的传送器官，现在的秘结没有其他原因，只是肺气浑浊罢了。紫菀能清肃肺气，所以能使大便通畅。”从此史载之的医名大振，蔡元长对他深深敬服。（施彦执《比窗灸》）
常熟徐氏患有中气不足的病症，延请王时勉治疗。王时勉诊脉后说：“此症适宜用补剂，应当用人参。这就像筑基造屋，不能按日计算其建成，必须服药一百副才有望痊愈。”服药十副后，病情没有多少减轻，又另请一位医生，结果病势加重。再次请求王时勉诊治，王时勉诊脉后说：“你对我的医术信念不坚定，又改换其他药物，导致病情加重。”徐某不再隐瞒，说曾服用过理气的药剂。王时勉说：“如果听从我的话就能痊愈，否则就不是我能救治的了。”徐某听从了他的建议，果然到了预定时间而痊愈。我曾经在《格致余论》中看到记载：浦江郑君在仲夏患痢疾，丹溪煎制人参膏给他服用，服到五斤时痢疾停止，服到十斤时疾病完全康复。现在的人轻视身体重视钱财，不顾体质的强弱、病情的深浅，急于求效。何况那些谋利嗜财之徒，动辄施用刚烈峻猛的劫剂，导致轻病变重，重病至危，这种情况往往发生。古人有句话说：“不死于病，而死于医”，能不谨慎吗？
Tongpan Yang (courtesy name Xuan) of Suzhou Prefecture enjoyed studying medical texts. Whenever a family member fell ill, he would manage the treatment himself. His sister suffered from heatstroke due to fatigue and overwork in June. She self-administered formulas such as Liuhe Tang (Six Harmonies Decoction) and Xiangru Yin (Elsholtzia Drink), which instead aggravated her condition, causing deficiency fire to rise, resulting in facial redness and body heat. Later, Liu Zongxu was invited to examine her. Her six pulses were rapid and frequent; the pulses at the three positions (cun, guan, chi) were wide and empty yet forceless. Liu said, "This illness initially arose from insufficient middle qi and internal injury caused by raw fruits, vegetables, and uncooked food, leading to internal deficiency and fever. This cannot be treated with Liuhe Tang or Xiangru Yin. Moreover, during summer months, yin cold is latent within the interior. If heavy cold medicines are added, they combine with this latent yin, creating a syndrome of excessive yin repelling yang. It is urgent to use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with 3 qian of Fuzi (Prepared Aconite Root) and 1 qian of Wei Jiangyan (Baked Dried Ginger Rhizome) decocted together. The liquid should then be immersed in ice to cool it before administration." That night, she slept soundly, and by dawn, she had a slight sweat and recovered. Yang bowed and thanked him, saying, "I have understood the concept of 'latent yin,' but I do not understand why the medicine should be cooled with ice." Liu replied, "This is precisely the principle of 'treating heat with cold' and 'treating cold with heat' found in the *Neijing* (Inner Canon). What is difficult about it?" Yang was greatly convinced and admired.
Cai Yuanzhang of the Song Dynasty suffered from severe constipation. Imperial physicians could not find remedies to promote bowel movement, largely because Cai refused to take Dahuang (Rhubarb Root and Rhizome). At that time, Shi Zaizhi was unknown and went to visit him. After being delayed and obstructed by the gatekeeper for a long time, he finally gained an audience. After examining the pulse, Shi wanted to demonstrate his unique skill and requested twenty coins. Cai asked what for, and Shi replied he wished to purchase Ziwan (Asteris Radix et Rhizoma). Shi then administered powdered Ziwan, and shortly after, his bowels moved freely. Cai was astonished and asked for the reason. Shi explained, "The large intestine is the transmission organ of the lung. The current constipation is due solely to turbid lung qi. Ziwan can clear and purify lung qi, thereby facilitating bowel movement." From this incident, Shi's medical reputation spread widely, and Cai deeply respected and submitted to him. (Shi Yanzhi, *Bichuang Jiu*)
Xu of Changshu suffered from insufficient middle qi and invited Wang Shimian for treatment. Wang examined the pulse and said, "This syndrome requires tonification; Ginseng should be used. Building a foundation is like constructing a house; its completion cannot be measured by days. One must take one hundred doses to expect recovery." After ten doses, there was little improvement. Another doctor was consulted, and the condition worsened. Xu sought Wang again. Wang examined the pulse and said, "Your faith in my method is lacking, and changing to other medicines has exacerbated your condition." Xu confessed that he had taken qi-regulating agents. Wang said, "If you follow my advice, you will recover; otherwise, I cannot save you." Xu complied, and indeed recovered at the expected time. I once read in *Gezhi Yulun* (Remains of Gezhi) that Mr. Zheng of Pujiang suffered from dysentery in midsummer. Danxi prepared Ren Shen Gao (Ginseng Paste) for him. After consuming five jin (approx. 2.5 kg), the dysentery stopped; after ten jin, the illness was fully resolved. Today's people value wealth over their bodies, disregarding physical strength and the depth of disease, seeking quick effects. Furthermore, those driven by profit often administer harsh, drastic purgatives, turning mild illnesses into severe ones and critical conditions into fatal ones. As the ancients said, "One does not die from the disease, but from the physician." Can one not be cautious?
