朱思古是眉州人，三十岁时患病，无法进食，闻到荤腥气味就会呕吐，只能使用大锅现煮汤来浇淡饭，多次食用。医生们都无法治愈。
史载之说：世俗之人不研读医经，却妄图治疗他人的疾病，真是令人感叹和惊骇。您的病症在《素问》中有记载，名为“食挂”。正常人的肺有六叶，舒展张开并覆盖在下方的脾脏之上，母子（脾土生肺金）之气调和，就能进食；一旦气机逆乱，肺就不能舒展，脾脏因此受损，所以不喜欢吃东西。于是传授给他一个方子，以清肺气、润肺燥为治疗方法，服用三天后，病人闻到肉味觉得香，吃下去觉得很美味。这件事宋人在传记中有所记载，但我考察岐黄之书（中医经典），都没有“食挂”这一说法。或许是记录者假托之名，或者是史公故意妄言以欺骗世人、迷惑大众呢？这两种情况都不可知。
现在的人指着那些胡须眉毛像雪一样白而肌肉纯白的人，认为这是因为社日受胎所致，所以男孩叫“社公”，女孩叫“社婆”。这种说法是错误的。根据徐巽的《胎育产化论》所说，受孕之时，母亲的月经正在行经，营血泛溢，所以形成的胎儿肌肉颜色洁白，这就是褚氏《遗书》中所说的“血先肌肤则身白”的道理。又有人问：为什么毛发全白且眼睛视力模糊不清呢？《内经》说：“毛发者，血之余。”又说：“肝受血而能视。”如今正值月经来潮，血液耗损，导致肝虚，毛发失去滋润，眼睛失去滋养，所以出现这种情况。这个道理很清楚，足以破除愚昧者的困惑。（出自《席上辅谈》）
王荆公（王安石）解释“痛”字说：应当通畅而受阻滞则为痛。现在的医生凡是遇到疼痛，就必须使用通利脏腑的方法，所以说“诸痛为实，痛随利减”。世俗之人把“利”理解为泻下。假如疼痛在表，属于实证；疼痛在里，属于实证；疼痛在血气，也属于实证。所以在表的用发汗法就能痊愈，在里的用泻下法就能痊愈，在血气的用消散、行气活血法就能痊愈。怎么能把“利”仅仅理解为泻下呢？应该将“利”解释为“通”的意思就可以了。所以经文说“通则不痛，痛则不通”，就是这个道理。
空同子说：夏季阳气发散于体表，伏阴潜伏在内，就像丝线一样未断绝的阴气潜伏着等待时机，夏至时阴气初生，如同冬至时阳气复生一样。验证井泉水温可知，阴气的潜伏也在九渊之底。患暑病的人用大顺散治疗，其中干姜、肉桂是大热之药，这是专门为过量饮用冰水、瓜果的人设立的，并不是为了治疗伏阴而使用的。这正是丹溪先生所说的“阴”字有虚弱之意，如果把它看作阴冷之邪，那就错误得很严重了。经文说“春夏养阳，秋冬养阴”，王太仆注释说春天吃温性食物，夏天吃寒性食物，这就是抑制过盛之阳、扶助不足之阴的意义。
Zhu Sigu, a native of Meizhou, fell ill at the age of thirty. He was unable to eat and vomited upon smelling meat or fish. He could only consume plain rice washed down with freshly boiled soup prepared in a large cauldron, eating frequently. Physicians were unable to cure him.
Shi Zaizhi stated: "It is lamentable and astonishing that commoners, who do not study medical classics, presumptuously attempt to treat others' diseases. Your condition is described in the *Suwen* (Basic Questions) as 'Shi Gua' (Food Hanging). In a healthy person, the six lobes of the lungs expand and cover the spleen below. When the mother (spleen/earth) and child (lung/metal) qi are harmonious, one can eat. If there is any deviation, the lungs cannot expand, causing damage to the spleen, thus leading to anorexia." He then prescribed a formula aimed at clearing lung qi and moistening lung dryness. After three days of taking it, the patient found the smell of meat fragrant and ate it with great relish. This incident was recorded in Song dynasty biographies. However, upon examining the texts of Qihuang (traditional Chinese medicine classics), I found no mention of "Shi Gua." It may be a fabrication by the recorder, or perhaps Mr. Shi fabricated it to deceive and confuse the world. Both possibilities remain unknown.
Some people point to individuals whose eyebrows and hair are white as snow while their muscles remain pure white, claiming this results from conception on the Day of She (She Ri), hence calling males "She Gong" and females "She Po." This theory is incorrect. According to Xu Xun's *Tai Yu Chan Hua Lun* (Treatise on Fetal Nurturing and Childbirth Transformation), conception occurs when the mother's menstrual blood is flowing and Ying blood (nutritive blood) is overflowing; thus, the fetus has pure white muscle tissue. This aligns with what is stated in Chu Shi's *Yi Shu*: "If blood precedes the skin and flesh, the body becomes white." Another question arises: why do some have completely white hair and blurred vision? The Classics state: "Hair is the surplus of blood," and "The liver receives blood and enables vision." Now, during menstruation, blood is depleted, leading to liver deficiency. Hair loses its nourishment, and the eyes lose their sustenance, resulting in these symptoms. This logic is clear and sufficient to dispel the confusion of the ignorant (from *Xi Shang Fu Tan*).
Wang Jinggong (Wang Anshi) explained the character "Tong" (pain/blockage): Pain arises when flow should be smooth but is obstructed. Modern physicians often use methods to unblock and purify the zang-fu organs for pain, stating "All pains are excess conditions; pain diminishes with purgation." Laypeople interpret "purge" (li) as downward evacuation. Suppose pain is in the exterior, it is an excess condition; if in the interior, it is excess; if in blood and qi, it is also excess. Therefore, exterior excess is cured by sweating; interior excess is cured by purging; blood and qi stagnation is cured by dispersing and promoting circulation. How can "purge" be limited to downward evacuation? "Li" should be interpreted as "Tong" (unblocked/free flow). Thus, the Classic says: "When there is free flow, there is no pain; where there is pain, there is no free flow." This is the meaning.
Kongtongzi said: In summer, Yang qi dissipates outward, while Yin cold hides within. This hidden Yin is like a thread, latent waiting for its time, similar to how Yang returns at Winter Solstice. Observing well water reveals that hidden Yin lies deep in the abyss. Summerheat illness is treated with Da Shun San (Great Harmony Powder), containing ginger and cinnamon, which are hot-natured herbs. These were specifically designed for those who overconsumed ice water and fruits, not for treating hidden Yin. This reflects Danxi's view that "Yin" implies deficiency rather than cold pathogen. Interpreting it as cold pathogen is a grave error. The Classic states "Nourish Yang in Spring and Summer, Nourish Yin in Autumn and Winter." Wang Taipu annotated this as consuming warm foods in spring and cold foods in summer, embodying the principle of suppressing excessive Yang and supporting deficient Yin.
