Safety. Jiao Ai Tang is recorded in Jingui Yaolüe, in the chapters on women's disorders, and is also known as Xiong Gui Jiao Ai Tang. Structurally it is Si Wu Tang — dang gui, chuan xiong, shao yao, di huang — with e jiao, ai ye and gan cao added, so for a reader of this library it is recognisable as a familiar base put to a specific purpose. The classical passage is precise about which situations it addresses: persistent spotting, bleeding that continues after a miscarriage, and bleeding during pregnancy where there is also abdominal pain, which the text calls a blockage in the womb. It is a formula for blood loss in the context of pregnancy and the puerperium, and this entry's first obligation is therefore not to explain the theory but to be clear about what that context means today.
Bleeding in pregnancy is not a self-management situation, and it is the clearest example of that principle in this batch. The list includes threatened miscarriage, and it also includes ectopic pregnancy, which is counted in hours to days and can kill; molar pregnancy; placental abruption and placenta praevia; cervical and other structural causes. Any vaginal bleeding in pregnancy warrants assessment by obstetrics, and one specific thing that assessment decides is whether anti-D immunoglobulin is indicated, which is a matter of blood group and timing rather than of anything a formula addresses. Bleeding that continues after a miscarriage must exclude retained products of conception. Bleeding after the menopause has to exclude endometrial cancer. In someone who is not pregnant, abnormal uterine bleeding still has a list that includes thyroid disease, bleeding disorders such as von Willebrand disease and thrombocytopenia, and structural causes including fibroids, polyps, adenomyosis, hyperplasia and malignancy. None of this is settled before it is looked at, and the cost of looking late is not evenly distributed.
On the ingredients, three cautions. E jiao is made by boiling donkey hide. It is an animal product and therefore unsuitable for vegetarian, halal and kosher diets, and it has a documented adulteration history: hides of other animals and, in reported cases, tannery offcuts have been substituted, with chromium raised as one of the contaminants. Ai ye is Artemisia argyi; its volatile oil contains camphor, cineole and thujone-type compounds, neurotoxicity at high intake is well described across the genus, and Artemisia pollen is one of the main autumn allergens in northern China, so cross-reactivity is a live question for people with pollen allergy. Gan cao, taken daily over time, causes pseudohyperaldosteronism with sodium and water retention, potassium loss and raised blood pressure, and is worse together with diuretics, digoxin or corticosteroids. The formula contains dang gui and chuan xiong, both traditionally treated with caution in pregnancy. This library states plainly that no medicine is taken in pregnancy on one's own decision, and that a formula of this kind is a matter for the treating obstetric team and a licensed practitioner together. It does not claim this formula stops bleeding, calms the womb, or prevents miscarriage or treats any specific disease.
胶艾汤著录于《金匮要略·妇人病》诸篇，又名**芎归胶艾汤**。结构上它是**四物汤**（当归、川芎、芍药、地黄）加阿胶、艾叶、甘草 —— 对本库的读者来说，这是「熟悉的底方被派去做一件具体的事」。古典原文对所主的情形很精确：**漏下不止；半产后继续下血不止；妊娠下血且腹中痛（原文称为「胞阻」）**。这是一首用于**妊娠与产褥期出血**的方，因此本条的首要义务不是解释理论，而是说清这个语境在今天意味着什么。
**孕期出血不是自行处置的情形**，而且它是本批里这一原则最清楚的例子。清单里包含**先兆流产**，也包含**异位妊娠**（以小时到天计，可以致命）、**葡萄胎**、**胎盘早剥与前置胎盘**、以及宫颈与其他结构性原因。**任何孕期阴道出血都应由产科评估**，而这次评估所决定的事项之一就是**是否需要抗 D 免疫球蛋白** —— 那是血型与时机的问题，不是任何方剂所能处理的。半产后出血不止须排除宫内残留。绝经后出血须排除子宫内膜癌。非孕期者的异常子宫出血，清单里仍有甲状腺疾病、凝血障碍（如 von Willebrand 病与血小板减少），以及肌瘤、息肉、腺肌症、内膜增生与恶性病变等结构性原因。**这些没有一项是能在不看的情况下了结的**，而看晚了的代价并不是平均分布的。
药味上有三点提示。**阿胶由驴皮熬制**：属动物制品，素食／清真／洁食不宜；并且它有明确的掺伪史 —— **曾有其他动物皮、乃至制革下脚料被充作原料的报道，铬是其中被点出的污染物之一**。**艾叶是 Artemisia argyi（艾属）**：挥发油含樟脑、桉油精与侧柏酮类成分，**大剂量挥发油的神经毒性在艾属植物中有充分描述**；而**艾属花粉是中国北方秋季主要过敏原之一**，故对花粉过敏者的交叉反应是一个实际存在的问题。**甘草**长期每日摄入可致假性醛固酮增多症（钠水潴留、失钾、升压），与利尿剂、地高辛、糖皮质激素叠加更重而非更轻。方中另有当归与川芎，二者在孕期传统上均被谨慎对待。本库在此明确：**孕期不使用任何自行决定的药物**；这一类方剂须由**主诊产科团队与执业中医师共同**决定。本库不声称本方能止血、安胎，或预防流产、或治疗任何具体疾病。
