（郁金）味辛、苦，性平，无毒。《本草》认为它性寒，这是错误的。哪有气味辛香却性质寒凉的道理呢？四川产的郁金，形状圆而尾部尖锐，像蝉的腹部一样，发芽处有一个小孔，外皮黄色带黑色，全身粗糙皱缩如同梧桐子的纹路，每枚大约重半钱，掰开后质地坚硬，颜色黄中带紫黑，闻起来有微弱的香气但不刺鼻，这才是真品。如果大小不一、色黄、皮上有细横纹、有像线一样的须根，掰开后中间空心、质地柔软、内外都是黄色、气味浓烈刺鼻的，就是片子姜黄。形状圆、首尾相似，全身有横纹，发芽处没有小孔，掰开后气味浓烈触鼻的，是染色姜黄中较小的那种。莪术则是大块状、颜色青黑，其中最大的是广术，这与郁金不类似。苏恭不能区分它们，认为是一物，这是谬误。
发明：郁金辛香而不猛烈，药性先升后降，归入心和心包络经。用于治疗吐血、鼻出血、唾血等带有血腥味的出血症，以及破除恶血。对于血淋、尿血、妇女月经逆行、产后败血冲心，以及陈旧性瘀血引起的心痛，都适宜服用郁金粉末，加入姜汁和童便（儿童尿液）同服，血液自然清静。如果是痰中带血，加入竹沥。又有鼻血上行不止的情况，可加入四物汤中。有一位妇女患失心风癫证十年，用郁金四两，佐以明矾一两制成丸剂，朱砂为衣，刚服用五十丸，感觉心中好像有东西脱落，再服用后苏醒。这是因为郁金入心去除恶血，明矾化解顽痰，朱砂安神的作用。郁金又能将症瘕积聚化为水液。岭南地区蛊毒为害，刚开始觉得胸腹疼痛时，立即用升麻或胆矾催吐。如果是膈下急痛，用米汤调服郁金粉末三钱，就会排出恶物。或者配合升麻、郁金一起服用，不呕吐就会腹泻，这是李巽岩担任雷州司理时，审理案件得到此方，救活了很多人的案例。按语：以上各种治疗，其功效都在破血生新。当今世人错误地把它当作各种出血症的圣药，患者不惜花费重金，医生借此牟利，都用姜黄来冒充，危害不小。凡是属于阴虚失血，以及阴火逼迫血液上逆的情况，都绝对禁忌使用。
(Pungent, bitter, neutral in nature, non-toxic.) The *Bencao* (Compendium of Materia Medica) considers it cold in nature, which is a mistake. How can there be something that is pungent and aromatic yet cold in nature? Those produced in Shu (Sichuan) are round with sharp tails, resembling the abdomen of a cicada. There is a small hole at the sprouting point. The skin is yellow with black tinges, and the entire body is rough and wrinkled like the texture of a parasol tree seed. Each piece weighs approximately half a qian. When broken open, the substance is hard, yellowish with purple-black hues, and emits a faint fragrance without being overpowering; this is the authentic product. If the pieces vary in size, are yellow, have fine transverse wrinkles on the skin, possess thread-like roots, are hollow inside when broken, soft in texture, yellow both inside and out, and have a strong, pungent odor, they are slices of Turmeric Rhizome (*Curcumae Longae Rhizoma*). If they are round, similar at both ends, have transverse wrinkles all over, no small hole at the sprouting point, and emit a strong, nose-piercing odor when broken, they are smaller pieces of dyed Turmeric Rhizome. Curcuma Zedoaria Rhizome (*Zedoariae Rhizoma*) consists of large chunks, greenish-black in color; the largest type is Guang Zedoaria Rhizome, which is distinct from this. Su Gong failed to distinguish them and considered them the same substance, which is erroneous.
Elucidation: Jinyu is pungent and aromatic but not harsh. Its action first ascends and then descends, entering the Heart and Pericardium channels. It treats hematemesis (vomiting blood), epistaxis (nosebleed), and hemoptysis/sputum with blood, breaking up bad blood. For strangury with blood (hematuria), bloody urine, retrograde menstruation in women, postpartum retained blood rushing to the heart, and heart pain due to old blood stasis, it is appropriate to take Jinyu powder mixed with ginger juice and child's urine (Tongbian). The blood will naturally clear. For phlegm containing blood, add Bamboo Sap (Zhuli). For upward-flowing epistaxis, add it to Siwu Tang (Four Substances Decoction). A woman suffered from "Shixin Fengdian" (Heart-Loss Wind-Mania) for ten years. She was prescribed pills made of four liang of Jinyu assisted by one liang of Alum (Mingfan), coated with Cinnabar (Zhusha). After taking only fifty pills, she felt as if an object had been removed from her heart; after taking more, she regained consciousness. This is because Jinyu enters the Heart to remove bad blood, Alum resolves stubborn phlegm, and Cinnabar calms the spirit. Jinyu can also transform masses into fluid. In Lingnan, where Gu poison causes harm, if chest and abdominal pain are initially felt, immediately induce vomiting using Shengma or Danchan. If there is urgent pain below the diaphragm, mix three qian of Jinyu powder with rice soup and ingest it; this will cause the discharge of evil substances. Alternatively, take it combined with Shengma and Jinyu; if vomiting does not occur, diarrhea will follow. This prescription was obtained by Li Xuyan while serving as the Judicial Administrator of Leizhou during case trials, saving many lives. Commentary: The efficacy of the above treatments lies primarily in breaking blood and generating new blood. Nowadays, people mistakenly regard it as a holy medicine for all types of bleeding. Patients do not spare heavy expenses, and physicians use it to profit, often substituting it with Turmeric Rhizome, causing significant harm. It is strictly contraindicated for deficiency-type hemorrhage due to Yin deficiency, and for upward reversal of blood forced by Yin fire.
