韶州曲江县人刘从周精通医术，有自己独到的见解，著有十篇文章，大体上与世俗观点不同。他论述痢疾时说：常人认为白痢是寒证，赤痢是热证，所以使用的药物如同冰炭般截然不同，其实并非如此。只要手足温暖，就属于热证，应当用米汤调服五苓散，继而又服用感应丸二十粒，即可痊愈；如果手足厥冷，就属于寒证，应当服用已寒丸之类的药物。凡是治疗痢疾，都应当以此（手足冷暖）来辨别，起初不要问大便颜色是红是白。至于盛夏时节发热，有伤寒和冒暑两种证候，如果发热时有轻有重，就是冒暑；如果一直发热不止，就是伤寒，应当以此区别。
有一户人家女儿生病肿胀，请了医生来看，都不能识别病因。马嗣明询问病情，患者说：曾经用手拔麦穗，当时有一个红色的物体长约二尺左右，像蛇一样钻入手指中，因为惊吓而跌倒，随即觉得手臂疼痛肿胀，一个多月后逐渐波及半身，四肢关节都肿痛难忍。马嗣明开具处方进行治疗，全都治愈了。（出自刘颖叔《异苑》）
华佗是沛国谯县人，通晓养生之道，年纪将近百岁，但容貌依然像壮年人，当时的人认为他是神仙。他精于方药，开出的处方不过几种，心中清楚药物的分量，不需要借助秤量；针灸只取几个穴位。如果疾病发作结聚在体内深处，针药无法达到的地方，就让病人先喝酒服用麻沸散，醉得没有知觉后，于是割开腹部背部，切除积聚物；如果在肠胃，就切断截除，清洗去除病秽，然后缝合伤口，敷上神膏，四五天伤口愈合，一个月之间身体完全恢复。
《华佗传》记载：一位士大夫身体不适，华佗说：“您的病很深，应当剖开腹部取出病灶，然而您的寿命也不超过十年，这病杀不死您，忍受病痛十年，寿命也到头了，不值得为此自找痛苦去剖腹。”士大夫不能忍受痛痒，一定要除去病根，华佗于是动手手术，患病不久就好了，十年后果然去世。（出自《三国志·魏书》）
扁鹊经过齐国，初次见到齐桓侯说：“您有病。”齐桓侯不理会。后来又见到他说：“您有病，现在还可以治疗。”齐桓侯说：“你想医治没病的人来求取功劳。”再后来见到他，扁鹊便走开了。几天后病情发作，派人召扁鹊，扁鹊说：“当初见您时，病在皮肤，针灸可以触及；第二次见您，病在血脉，汤药可以到达；现在见您，病已进入骨髓，掌管生命的神灵也无能为力了。”过了几天，齐桓侯果然去世了。
Liu Congzhou, a native of Qujiang County in Shaozhou, was skilled in medical arts and held unique insights. He wrote ten essays that largely differed from secular views. In his discussion on dysentery (Li Ji), he stated: Common people consider white dysentery as a cold syndrome (Han Zheng) and red dysentery as a heat syndrome (Re Zheng), thus using medications as opposite as ice and charcoal. This is actually incorrect. If the hands and feet are warm, it indicates a heat syndrome; one should decoct rice soup to mix with Wuling San (Five-Ingredient Powder with Poria), followed by taking twenty pills of Yinggan Wan (Miraculous Response Pill), which will lead to recovery. If the hands and feet are cold, it indicates a cold syndrome; one should take Yihan Wan (Already-Cold Pill) or similar formulas. When treating dysentery, differentiation should be based on this (temperature of extremities), regardless of whether the stool is red or white initially. Regarding fever in midsummer, there are two syndromes: Shanghan (Cold Damage) and Maoshu (Summerheat Invasion). If fever fluctuates, it is Maoshu; if fever persists continuously without abating, it is Shanghan; these should be differentiated accordingly.
The daughter of a certain household suffered from swelling. Physicians were summoned but could not identify the cause. Ma Siming asked about the origin of the illness. The patient replied: While pulling wheat ears by hand, a red object approximately two chi long, resembling a snake, entered her finger. She fainted from fright and subsequently felt pain and swelling in her arm. Over more than a month, the condition spread to half her body, causing unbearable pain and swelling in all joints. Ma Siming prescribed treatment, and she recovered completely. (From Liu Yingshu's *Yi Yuan*)
Hua Tuo was from Qiao County in Peiguo. He mastered the art of preserving life and health. Approaching a hundred years old, his appearance remained that of a vigorous adult, leading contemporaries to believe he was an immortal. He was proficient in herbal prescriptions, typically prescribing no more than a few ingredients, accurately estimating dosages by heart without needing scales. His acupuncture involved only a few acupoints. If a disease manifested as internal accumulation beyond the reach of needles and herbs, he would have the patient drink wine mixed with Mafei San (Numbing Powder). Once the patient was intoxicated and unconscious, he would incise the abdomen and back to remove accumulations. If the pathology was in the intestines and stomach, he would resect and wash away the diseased tissue, then suture the wound and apply Shen Gao (Divine Ointment). The wound healed in four or five days, and full recovery occurred within a month.
According to the *Biography of Hua Tuo*: A scholar-official felt unwell. Hua Tuo said, "Your disease is deep-seated and requires surgical removal from the abdomen. However, your lifespan will not exceed ten years. This disease will not kill you; endure the pain for ten years, and your natural life will end. There is no need to subject yourself to such surgery." The scholar-official could not tolerate the itching and pain and insisted on removing the disease. Hua Tuo proceeded with the operation, and the patient recovered shortly after. Ten years later, he indeed passed away. (From *Records of the Three Kingdoms*, Book of Wei)
When Bian Que passed through Qi, he first met Duke Huan of Qi and said, "You have a disease." The Duke ignored him. Upon meeting again, Bian Que said, "You have a disease, but it is still treatable." The Duke said, "You wish to treat healthy people to claim credit." On the third encounter, Bian Que walked away. A few days later, symptoms appeared, and the Duke summoned Bian Que. Bian Que remarked, "Initially, when I saw you, the disease was in the skin, accessible by acupuncture. Secondly, it was in the blood vessels, accessible by herbal decoctions. Now, seeing you, the disease has penetrated into the bone marrow. Even the Lord of Life cannot help." A few days later, Duke Huan died.
