朱丹溪曰∶或问初产之妇，好血已亏，污血或留，彼黑神散非要药乎？答曰∶至哉坤元，万物资生，理之常
也。初产之妇，好血未必亏，污血未必积，脏腑未必寒，何以药为。饮食起居，勤加调护，何病之有。诚有
污血体怯而寒，服之或可。若有他病，当求病起何因，病在何经。气病治气，血病治血，寒者温之，热者清之，
凝者行之，虚者补之，血多者止之，何用海制此方，例令服饵，不恤无病生病。彼黑神散用干姜、当归之温热，
黑豆之甘，熟地之浓，以补血之虚。佐以炒蒲黄，防出血之多。芍药之酸寒，有收有散，为四药之助。肉桂大
辛热，以行滞血。和以甘草之缓。其取用似乎精密，然驱逐与补益，似难同方施治。设有性急者，形瘦者，本有

朱丹溪说：有人问，刚生产完的妇女，好血（指正常的血液）已经亏损，污血（指恶露等瘀血）或许滞留，那黑神散不是必要的药物吗？回答说：坤元（指大地孕育万物的本源）是伟大的，万物依靠它生长，这是自然的常理。刚生产完的妇女，好血未必亏损，污血未必积聚，脏腑未必寒冷，为什么要用药呢？饮食起居方面，只要勤于加以调养护理，会有什么疾病呢？确实如果有污血滞留、体质虚弱且伴有寒象的，服用它或许可以。但如果患有其他疾病，应当探究病因是什么，病在哪个经络。气病治气，血病治血，寒证用温法，热证用清法，凝滞者行散，虚损者补益，血多者止血，何必拘泥于这个方子，一律让人服用，不顾及让无病之人致病。那个黑神散使用干姜、当归的温热之性，黑豆的甘味，熟地黄的浓腻，来补血虚。辅以炒蒲黄，防止出血过多。芍药的酸寒之性，既有收敛又有发散作用，作为前四味药的辅助。肉桂大辛大热，用来推动停滞的血。配合甘草的缓和之性。它的配伍似乎精密，然而驱逐瘀血与补益正气，似乎难以在同一方剂中施治。假设有性情急躁的人，形体消瘦的人，原本就有怒火的人，夏季坐月子的人，正值火令之时，干姜、肉桂都是禁药，虽然是补剂，也有偏胜之弊，脏腑没有寒邪，哪里承受得住。必须摒弃黑神散。那些富贵人家，骄纵惯养的妇女，突然患上白带、头风、气痛、胸膈胀满、痰逆、口干，月经不调，头发脱落，身体疲倦，这些都是阳盛阴虚的表现。天生的气血，本来平和，说是盛、说是虚，又怎么知道不是这些迷误错误的做法导致的呢？
张璜按语：产妇有禀赋瘦弱且偏热的，素有郁火积热的，多次生产导致冲任二脉血枯脉涩的，一旦产后，出现儿枕痛（产后腹痛），粗劣的医生固执于古方，妄投肉桂，灾祸立刻就会降临。所以必须是严寒天气冻产，风寒乘虚而入，血瘀不行，才投用肉桂，以通行血脉。
Zhu Danxi said: One may ask, regarding women who have just given birth, whose good blood (normal blood) is already deficient and whose foul blood (lochia or stasis) may be retained, is Black Spirit Powder not an essential medicine? The answer is: The Kun Yuan (the primal power of the Earth that nurtures all things) is profound; all things rely on it for life, which is the constant principle. For women who have just delivered, good blood is not necessarily deficient, foul blood is not necessarily accumulated, and the Zang-Fu organs are not necessarily cold; why use medicine? If one diligently cares for diet and daily life, what illness would there be? Indeed, if there is retained foul blood, a weak constitution, and cold signs, taking it might be acceptable. However, if other diseases exist, one must seek the cause of the illness and determine which meridian is affected. Treat Qi disorders by regulating Qi, treat Blood disorders by regulating Blood, warm the cold, clear the heat, move stagnation, tonify deficiency, and stop excessive bleeding. Why adhere rigidly to this formula and order everyone to take it, disregarding the harm of causing disease in those without illness? Black Spirit Powder uses the warming properties of Gan Jiang (Dried Ginger) and Dang Gui (Angelica Sinensis), the sweetness of Hei Dou (Black Soybean), and the richness of Shu Di Huang (Prepared Rehmannia Root) to tonify Blood deficiency. It is assisted by Chao Pu Huang (Fried Sparganii Pollen) to prevent excessive bleeding. Shao Yao (Peony Root), with its sour and cold nature, possesses both astringent and dispersing properties, aiding the previous four herbs. Rou Gui (Cinnamon Bark), being greatly acrid and hot, moves stagnant blood. This is harmonized by the moderating effect of Gan Cao (Licorice Root). Its formulation seems precise; however, expelling stasis and tonifying deficiency seem difficult to treat simultaneously in the same prescription. Suppose there are individuals with irritable temperaments, thin bodies, pre-existing fire-anger, or those lying in during summer when the Fire phase is dominant; in such cases, Gan Jiang and Rou Gui are contraindicated. Although this is a tonic formula, it has biased effects. If the Zang-Fu organs lack cold, how can they tolerate it? One must discard Black Spirit Powder. In wealthy families, indulgent women may suddenly suffer from leukorrhea, wind-headache, Qi-pain, chest fullness, rebellious phlegm, dry mouth, irregular menstruation, hair loss, and fatigue. These are all manifestations of Excess Yang and Deficient Yin. Innate Qi and Blood are originally balanced. To speak of "Excess" or "Deficiency," how do we know these were not precipitated by such misguided practices?
Zhang Huang commented: Parturients with a constitutional tendency towards thinness and heat, or those with chronic郁火 (depressed fire) and accumulated heat, or those whose Chong and Ren meridians are depleted and pulses are choppy due to multiple births, may experience Er Zhen Tong (postpartum abdominal pain caused by uterine contraction/stasis) after delivery. Crude practitioners, sticking rigidly to ancient formulas, recklessly administer Rou Gui (Cinnamon Bark), bringing disaster swiftly. Therefore, Rou Gui should only be administered when childbirth occurs in severe cold, wind-cold invades due to deficiency, and blood stasis prevents flow, in order to promote the circulation of blood vessels.
