万历甲戌年，从仲秋到冬季，时行疫气盛行。三个月内，我诊治的男女婴孩共七十二人。其中，苕溪一带最有名望的家族是沈家，大中丞观颐公在担任考功郎中时，他的幼子喘咳不安，声音嘶哑，发热，腹泻，身上出现紫色斑点且无法收敛。我用小无比散治好了他。
沈夫人的怀孕期间，腹痛昏厥了五天。像高、陈两位名医（与沈家是姻亲）这样的大夫，无论大小事务都全权委托给他们，但也束手无策。我到达后诊察，发现她两手脉象都洪大，按照医法应当使用下法治疗，但众人皆因患者怀孕而反对。我说：“《内经》云：‘有故无殒，亦无殒也’（有病则病受之，不会伤害母体）。如今已怀孕九个月，即将分娩，胎动何来损伤？如果该用下法而不用，不仅疼痛难忍，而且病情变化不可预测。”考功郎中听从了我的话并请求开药，我便用小承气汤加紫苏梗、砂仁，服用后病情安定。
考功郎中偶然感受风邪，头痛倦怠，发冷发热如疟疾状，脉象弦浮而数。我说：“这是小柴胡汤证”，服一剂后痊愈。考功郎中请假回家居住已有二十年，非常喜爱医书。我刚到苕溪时，当地人还不了解我，考功郎中听说我的名声后，急切想认识我，认为我治病很神奇，又与我讨论伤寒、痘疹、胎产等理论，都切中要害，他深表赞同。他对人说：“优秀的宰相和优秀的医生是一样的，像孙君这样的造诣，即使千金也不足以衡量其价值。”特地在册子上撰写医说，以让孙君的名声不朽。
张孝廉后渠，三十多岁，患大头瘟。头部肿大如斗。脖子看不见，嘴唇下垂至胸部，面色像紫色的猪肝，神志昏迷不知人事。见到的人惊恐逃跑。那年疫病严重，人们害怕传染，以致于废除了吊唁和庆贺的礼仪。张孝廉与考功郎中的公子，曾在会稽陶春源处共同学习《春秋》，陶春源邀请我去诊治。他们的脉象都是浮弦而数。起初我用柴胡一两，黄芩、玄参各三钱，薄荷、连翘、葛根各二钱，甘草一钱，服用三剂后，寒热退去，弦脉减轻，但脉象转为洪大。我知道病邪传入了阳明经，于是改用贯众一两，葛根、天花粉各三钱，甘草一钱，黑豆四十九粒，服用一剂，肿胀消退了一半；再服一剂，完全消退。二十一天未进食浆液食物，后来再服两剂小柴胡汤，才开始能吃下两条手指粗细的干糕，第二天喝粥，病情逐渐平复。丁酉年秋天，科举考试捷报传来。
In the Jiaxu year of the Wanli reign, from mid-autumn to winter, epidemic pathogens prevailed. Within three months, I treated a total of seventy-two men, women, and infants among them. The most prominent family in the Tiao stream area was the Shen family. When Mr. Shu (courtesy name Guanyi), who held the title of Grand Minister of Ceremonies, served as Director of Evaluations, his youngest son suffered from wheezing and coughing with restlessness, hoarseness, fever, diarrhea, and purple macules that failed to resolve. I cured him using Xiaowubi San (Little Peerless Powder).
Mrs. Shen, while pregnant, experienced abdominal pain and fainting for five days. Renowned physicians such as Dr. Gao and Dr. Chen (who were relatives by marriage to the Shen family) were entrusted with all matters, great or small, yet they were unable to take any effective action. Upon my arrival, I palpated her pulse and found both hands presenting a flooding and large pulse. According to medical principles, purgation should be employed. However, everyone objected due to her pregnancy. I stated: "The Classic says: 'If there is an existing pathology, there will be no destruction [of the healthy qi], nor will there be destruction [of the fetus].'" She was already nine months pregnant and near delivery; how could fetal movement cause harm? If purgation is indicated but not administered, not only will the pain be unbearable, but unpredictable complications may arise. The Director of Evaluations accepted my advice and requested medicine. I prescribed Xiao Chengqi Tang (Minor Order the Yang Decoction) augmented with Perillae Caulis (Su Geng) and Amomum Fruit (Sha Ren). After administration, she stabilized.
The Director of Evaluations accidentally contracted wind pathogenic factors, resulting in headache, fatigue, chills, and fever resembling malaria, with a wiry, floating, and rapid pulse. I diagnosed this as a Xiao Chaihu Tang (Minor Bupleurum Decoction) pattern. One dose resulted in recovery. The Director of Evaluations had been on leave at home for twenty years and was deeply fond of medical texts. When I first arrived in Tiao, the locals did not know me. Hearing of my reputation, he eagerly sought to meet me, remarking that my treatments were remarkable. He also discussed Taiyang disease (Exterior Syndrome), variola (smallpox), and obstetrics with me, finding my insights accurate and profound, and agreed wholeheartedly. He told others: "An excellent chancellor and an excellent physician are alike. The attainment of Master Sun is such that even a thousand gold pieces cannot measure his worth." He specially wrote medical treatises in a booklet to ensure Master Sun's legacy would endure.
Scholar Zhang Houqu, in his thirties, suffered from Da Tou Yi (Great Head Epidemic / Plague of the Head). His head swelled as large as a bucket. His neck was invisible, his lips hung down to his chest, his complexion resembled purple liver, and he was comatose and unaware of his surroundings. Those who saw him fled in horror. That year, the epidemic was severe and virulent; people feared contagion, leading to the suspension of mourning and celebratory visits. Scholar Zhang and the son of the Director of Evaluations had jointly studied the Spring and Autumn Annals under Tao Chunyuan of Kuaiji. Tao invited me to examine Zhang. His pulse was floating, wiry, and rapid. Initially, I prescribed Bupleuri Radix (Chai Hu) 1 liang, Scutellariae Radix (Huang Qin) and Scrophulariae Radix (Xuan Shen) each 3 qian, Menthae Haplocalycis Herba (Bo He), Forsythiae Fructus (Lian Qiao), and Puerariae Radix (Ge Gen) each 2 qian, and Glycyrrhizae Radix et Rhizoma (Gan Cao) 1 qian. After three doses, the chills and fever subsided, and the wiry quality of the pulse diminished, leaving a flooding and large pulse. I deduced that the pathogen had transmitted to the Yangming channel. I then modified the prescription to use Cyperi Rhizoma (Guan Zhong) 1 liang, Puerariae Radix (Ge Gen) and Trichosanthis Radix (Tian Hua Fen) each 3 qian, Glycyrrhizae Radix et Rhizoma (Gan Cao) 1 qian, and Glycine Max Seed (Hei Dou) 49 grains. After one dose, half of the swelling subsided; after another dose, it completely resolved. For twenty-one days, he had not taken any liquid food. Subsequently, two doses of Xiao Chaihu Tang (Minor Bupleurum Decoction) were administered, after which he could consume two strips of dry cake, each the thickness of a finger. The next day, he consumed congee, and gradually recovered. In the autumn of the Dingyou year, news of success in the provincial examinations arrived.
