Safety. Three ingredients, and two of them are things a person eats anyway. That is precisely why this entry needs its safety notes written out rather than skipped — being edible is not the same as being appropriate here, and a formula made of food is the one most likely to be read as carrying no risk at all.
The word to stop on is 疝. In the classical line it names a pattern of abdominal and flank pain; today 疝 means a hernia, and a hernia is the reason this paragraph exists. An irreducible groin lump that is tender, or one accompanied by vomiting, distension or the inability to pass stool or flatus, is strangulation until a surgeon says otherwise, and ischaemia of the contained bowel is a matter of hours. Femoral hernias strangulate more often than inguinal ones and are more common in women. The same region produces other lumps that must be told apart: lymph nodes, hydrocele, varicocele, a femoral pseudoaneurysm, epididymitis — and testicular torsion, which has its own clock measured in hours and which can present with pain felt in the groin or lower abdomen rather than in the scrotum. This library records these as what a clinician carries; it offers no plan for a groin lump or for acute abdominal pain.
Then the second setting the text names: pain after childbirth. Postpartum abdominal pain has its own list, and it is not a dietary list — postpartum haemorrhage, endometritis, wound infection, mastitis, and, beyond the abdomen, pre-eclampsia presenting after delivery and sepsis. Pain with fever after delivery points toward those and away from food. This library states that direction and offers nothing further.
Now the three materials, each with its own record. 羊肉 is red meat. The IARC classification places processed meat in Group 1 and red meat in Group 2A, and that classification describes the strength of the evidence for a hazard, not the size of the risk — which is the honest way to state it. Red meat is also the antigen in alpha-gal syndrome, an allergy acquired after certain tick bites whose symptoms appear three to six hours after eating, so a reaction often lands in the night and is not connected back to dinner. Undercooked meat carries food-borne infection, and mutton is a real load of saturated fat and of haem iron, which matters to someone with haemochromatosis. 生姜 is fresh ginger; it is not 干姜, which is the dried form and has its own entry. Reports of an interaction with anticoagulants exist and the findings do not agree with one another, so this library records that reports exist and that they are inconsistent; gastric irritation from ginger is also recorded. 当归 is Angelica sinensis, in the carrot family — a family in which misidentification during foraging is genuinely dangerous, and in which water hemlock is lethal. It contains furanocoumarins, which photosensitise, and coumarin-type constituents; case reports of an interaction with warfarin exist, and this library records case reports as case reports rather than as an established effect. 当归 is not 欧当归 and not 白芷.
Reliable safety data for pregnancy and breastfeeding are lacking, and 当归 is traditionally listed among the herbs to be cautious with in pregnancy; this library does not suggest use in either state. Chinese-language literature reports observations of this class of formula, mostly small and methodologically limited; this library records that such studies exist, not that benefit has been established.
三味药，其中两味是本来就在吃的东西。正因为如此，这条的安全注释**必须写出来而不是跳过去** —— **能吃 ≠ 在这个场景里合适**；而「用食物组成的方」恰恰最容易被读成「没有任何风险」。
要停一下的是**「疝」**这个字。在条文里它是腹痛连及胁部的一组表现；而在今天，**疝就是疝气**，而疝气正是这一段存在的理由。**腹股沟区一个推不回去、有压痛的肿物**，或伴有呕吐、腹胀、不排气不排便的肿物，在外科医生给出别的答案之前就是**绞窄**，而其中肠管的缺血按**小时**计。**股疝比腹股沟疝更容易绞窄，且在女性更常见**。同一区域还有别的肿物要分开：淋巴结、鞘膜积液、精索静脉曲张、股动脉假性动脉瘤、附睾炎 —— 以及**睾丸扭转**，它有自己按小时计的时钟，且**疼痛可以落在腹股沟或下腹而不是阴囊**。本库把这些记成「临床上要抱在手里的」，**对腹股沟肿物与急性腹痛均不提供方案**。
第二个场景是条文另处所记的**产后腹痛**。产后腹痛有自己的一张表，而它不是食疗表：**产后出血、子宫内膜炎、切口感染、乳腺炎**，以及腹以外的事 —— **产后子痫前期**与**脓毒症**。**产后腹痛伴发热，指向的是这些，不是食物。** 本库只说方向，此外不给任何东西。
现在说三味本身，各有各的记载。**羊肉**是红肉：IARC 把加工肉列在第 1 类、红肉列在 2A 类 —— **这个分类描述的是「证据对危害的支持强度」，不是风险的大小**，这才是诚实的说法。红肉还是 **α-gal 综合征**的抗原：这是一种在某些蜱叮咬之后获得的过敏，**症状在进食后 3–6 小时才出现**，所以常发生在夜里而不会被联想到晚饭。未熟肉有食源性疾病的风险；羊肉也是真实的饱和脂肪与**血红素铁**负荷，对血色素沉着症者是要算的。**生姜**是鲜姜，**不是干姜**（干姜是干品，本库另有条目）；与抗凝药的相互作用**有报告而结论并不一致**，故本库记「有报告、且不一致」；生姜对胃黏膜的刺激亦有记载。**当归**是伞形科当归属 —— **伞形科是采挖时最容易认错的科，其中的毒芹可致死**。它含**呋喃香豆素**（光敏）与香豆素类成分；与华法林相互作用的**病例报告**是真实存在的，本库记「有病例报告」而**不记「已确立的效应」**。当归**不是欧当归，也不是白芷**。
孕期与哺乳期缺乏可靠的安全性数据，而当归传统上被列入孕期慎用之列；本库在这两种状态下均不主张使用。中文文献有本方一类方剂的观察报告，多为小规模、方法学有限；本库记「有这类研究」，**不记「疗效已被确立」**。
