吐泻生风眼上膜，风在眼中抓不着。
急惊过了喘无休，慢惊过了皮肤薄。
盘肠过了心中孤，嗽吐呕逆心凹恶。
伤寒赤脉青相交，结热面黑皮毛落。
痘子入腹眼不开，热泻出取口干恶。
锁口腰低唇黑青，积痢脾毒唇卷缩。
此病因惊无有积，岂有神仙留妙药。
罗谦甫案，一小儿五月间，因食冷粉，腹中作痛，遂于市药铺中赎得神芎丸服，脐腹渐
加冷痛，时发时止，逾七八年不已。因思古人云∶寒者热之，治寒以热，良医不能废其绳墨，
而更其道也。据所伤之物，寒也，所攻之药亦寒也。重寒伤胃，其为冷病可知矣。凡人之脾
胃，喜温而恶冷，况小儿血气尚弱，不任其寒，故阳气潜伏，寒毒留连，久而不除也。治病
必先其本，当用和中养气之药，以救前失，服之月余方愈。呜呼！康子具药，孔子曰∶未达
，不敢尝。此保生之重者也。奈何常拱默而令切脉，以谓能知病否。且脉者，人之血气，附
行经络之间。热胜则脉疾，寒胜则脉迟，实则有力，虚则无力。至于所伤何物，岂能别其形
象乎？医者不可不审其病源。且此子之父，不以病源告医，而求药于市肆，以致七年之病，
皆昧此理也。孙真人云∶未诊先问，最为有准。东坡云∶只图愈疾，不欲困医。二公之言有
功于世大矣。
吐泻引发肝风内动，眼睑出现翳膜，病邪在眼中难以察觉。
急惊风发作后若喘息不止，慢惊风发作后皮肤变得薄弱。
盘肠气痛过后心中孤独（指脾胃虚寒、心神失养），咳嗽呕吐逆气导致心窝凹陷且厌恶饮食。
伤寒病中赤脉与青脉交错，热邪结聚导致面色发黑、皮毛脱落。
痘疹毒邪入腹且眼睛不开，热性腹泻取利过度导致口干且厌恶饮食。
锁口风（破伤风）伴腰部低垂、嘴唇黑青，积滞痢疾脾脏有毒导致嘴唇卷缩。
这些病因多因受惊而无食积，哪里会有神仙留下灵丹妙药呢？
罗谦甫诊治一案：一个五月的婴儿，因为吃了冷米粉，腹部疼痛，于是从市井药铺买得神芎丸服用，脐腹部逐渐加重冷痛，时发时止，经过七八年仍未痊愈。因此想到古人说：“寒者热之”，治疗寒证要用热药，良医不能废弃法度而改变原则。根据所伤之物，是寒性的；所攻伐的药物也是寒性的。重寒损伤胃气，这显然是冷病。大凡人的脾胃，喜欢温暖而厌恶寒冷，何况小儿气血尚且虚弱，不能承受这种寒凉，所以阳气潜伏，寒毒留连，久而久之无法消除。治病必须先治其根本，应当使用调和中焦、滋养元气的药物，来补救之前的失误，服药一个多月才痊愈。唉！孔子有儿子孔鲤，孔子说：“还没见过他，不敢随便给他药吃。”这是保养生命的重要原则。为什么常人只是拱手沉默让医生切脉，就认为能知道病情呢？况且脉象，是人的血气依附运行在经络之间。热盛则脉搏急促，寒盛则脉搏迟缓，实证则有力，虚证则无力。至于究竟伤了什么东西，怎么能辨别出它的形象呢？医生不可以不仔细审察疾病的根源。况且这个孩子的父亲，不把病因告诉医生，却去市井求药，导致七年之病，都是不明白这个道理。孙思邈说：“未诊先问，最为准确。”苏东坡说：“只求治愈疾病，不想使医生困窘。”两位先生的言论对世人贡献很大啊。
Vomiting and diarrhea inducing internal wind, with membranes forming on the eyelids; the pathogenic factor in the eyes is elusive.
After acute convulsion (Ji Jing), if panting continues without cessation; after chronic convulsion (Man Jing), the skin becomes thin.
After intestinal colic (Pan Chang) has passed, the heart feels lonely (indicating deficiency of spleen-stomach and malnourishment of the heart spirit); coughing, vomiting, and regurgitation lead to a sunken epigastrium and aversion to food.
In cold damage (Shang Han), red pulses intersect with cyanotic pulses; heat accumulation causes black complexion and shedding of hair and skin.
When pox toxins enter the abdomen and the eyes remain unopened; excessive purgation for heat-type diarrhea leads to dry mouth and aversion to food.
Lockjaw (Suo Kou) accompanied by drooping waist and cyanotic lips; accumulated dysentery with spleen toxicity leads to curled lips.
These conditions arise from fright rather than food stagnation; how could there be immortal elixirs left behind?
Case of Luo Qianfu: An infant in May suffered abdominal pain due to consuming cold rice noodles. He subsequently purchased Shenxiong Wan (Caulis Ligustici Chuanxiong Pill) from a market pharmacy. The cold pain in the umbilical and abdominal regions gradually intensified, occurring intermittently for over seven years without resolution. Reflecting on the ancient saying, "For cold syndromes, use heat therapy," treating cold with heat is a principle that good physicians must not abandon or alter. The ingested substance was cold, and the administered medicine was also cold. Double cold damaging the stomach indicates a cold disease. Generally, the human spleen and stomach prefer warmth and dislike cold. Moreover, infants have weak blood and qi, unable to withstand such coldness. Thus, yang qi remains latent, cold pathogens linger, and the condition persists for a long time. Treating illness requires addressing the root first; one should use herbs to harmonize the middle jiao and nourish qi to remedy previous errors. After taking the medication for more than a month, the patient recovered. Alas! Confucius had a son named Kong Li. Confucius said, "I have not yet seen him, so I dare not give him medicine." This emphasizes the importance of preserving life. Why do laypeople merely stand aside silently allowing pulse diagnosis, assuming it suffices to know the disease? Pulse reflects the blood and qi circulating within the meridians. Excess heat results in rapid pulses; excess cold results in slow pulses. Excess patterns present with forceful pulses; deficiency patterns present with feeble pulses. How can one distinguish the specific nature of the ingested pathogen solely through pulse? Physicians must carefully investigate the source of the disease. Furthermore, the father of this child failed to inform the physician of the etiology, instead seeking remedies at the market, resulting in a seven-year ailment due to ignorance of this principle. Sun Simiao stated, "Inquiring before diagnosing yields the most accurate results." Su Dongpo said, "Seek only to cure the disease, do not seek to perplex the physician." The words of these two gentlemen have contributed greatly to the world.
