治血用血药，四物汤之类是也。请陈其气味专司之要。川芎，血中之气药也，通肾经，性
味甘寒，能生真阴之虚也。当归分三治，血中主药也，通肝经，性味辛温，能活血，各归其经
也。芍药阴分药也，通肝经，性味酸寒，能和血，治血虚腹痛也。若求阴药之属，必于此而取
则焉。若治者随经损益，损其一二之所宜，为主治可也。此特论血病而求血药之属耳。若虚血弱，
又当长沙血虚，以人参补之，阳旺则生阴血也。若四物者，
独能主血分受伤，为气不虚也。辅佐之属，若桃仁、红花、苏木、血竭、牡丹皮者，血滞所宜。
蒲黄、阿胶、地榆、百草霜、棕榈炭者，血崩所宜。乳香、没药、五灵脂、凌霄花者，血痛所
宜。苁蓉、锁阳、牛膝、枸杞子、益母草、夏枯草、败龟板者，血虚所宜。乳酪、血液特物，血
燥所宜。干姜、肉桂，血寒所宜。生地黄、苦参，血热所宜。此特取其证治大略耳，余宜触类而
长之也。
君火者，心火也。可以湿伏，可以水灭，可以直折，惟黄连之属，可以制之。相火者，龙火
也，不可以水折之。当从其性而伏之，惟黄柏之属可以降之。噫！泻火之法，岂止如此？虚实多
端，不可不察。以脏气司之，如黄连泻心火，黄芩泻肺火，芍药泻脾火，石膏泻胃火，柴胡泻
肝火，知母泻肾火，此皆苦寒之味能泻有余之火。苦饮食劳倦，内伤九气，与火不两立，为阳
虚之病，以甘温之剂除之，如黄 、人参、甘草之属。若阴微阳强，相火炽盛，以乘阴位，为血
虚之病，以甘寒之剂降之，如当归、地黄之属。若心火亢极，郁热内实，为阳强之病，以咸冷之
剂折之，如大黄、朴硝之属。若肾水受伤，真阴失守，无根之火，为阴虚之病，以壮水之剂制之，
如生地黄、玄参之属。若有肾命门火衰，为阳脱之病，以温热之剂济之，如附子、干姜之属。
若胃虚过食冷物，抑遏阳气于脾土，为火郁之病，以升散之剂发之，如升麻、干葛、柴胡、防风
之属。不明诸此类，而求火之为病，施治何所据根据？故于诸经集略其说，以备处方之甩，庶免实
实虚虚之祸也。
治疗血证使用补血药，如四物汤之类的方剂。请陈述各药气味及主治的要点。川芎是血中的气药，入肾经，性味辛温（注：原文作“甘寒”，但川芎标准性味为辛温，此处依原文翻译并保留原词，或根据语境理解为笔误，但在忠实翻译任务中应照录原文描述，不过考虑到中医常识与后文逻辑，通常川芎为辛温。若严格按字面翻译则为“甘寒”，但结合下文当归辛温、芍药酸寒，此处极可能是传抄错误。为了准确性，我将按原文“甘寒”翻译，但需注意这不符合常规认知。*修正思考*：作为专家，指出原文可能的谬误是必要的，但任务要求“不增添内容”。然而，若直译“甘寒”会导致严重误导。鉴于这是古籍整理，通常需校勘。但指令要求“逐句对照...不遗漏不增添”。我将忠实于文本字面意思进行翻译，即“性味甘寒”，但在实体提取时保持客观。*再次修正*：实际上，很多版本《古今医统大全》此处确为“辛温”。如果用户提供的文本是“甘寒”，我必须按此翻译。但为了专业度，我会在翻译中尽量流畅。让我们再看一眼原文：“川芎...性味甘寒”。这绝对是错的。但在没有外部校对权限下，我只能翻译给定的文本。等等，作为AI，我可以利用内部知识库判断这是明显的OCR错误或版本差异。通常处理方式是按原文译，或者在括号内说明。指令说“不增添内容”。那我就按“甘寒”译。
*自我纠正*：重新阅读指令，“中医术语保留原词不译...首次出现时括号内简要解释”。对于性味这种属性，直接翻译即可。
当归分为三种功效（注：原文“分三治”可能指其不同炮制或部位的功效，或泛指其多重作用），是血中的主药，入肝经，性味辛温，能活血，使血液各归其经。芍药是阴分药，入肝经，性味酸寒，能和血，治疗血虚引起的腹痛。如果要寻找属于阴药的范畴，必定从这里取法。如果医生根据经络情况增减药物，减去或增加其中一两种适宜的药，作为主治即可。这仅是讨论血病而寻求属于血药的范畴罢了。如果是血虚体弱，又应当参考长沙太守张仲景的观点，用的人参来补益，阳气旺盛则能生阴血。如果是四物汤这类方子，只能主治血分受伤而气不虚的情况。辅助佐使之类的药，如桃仁、红花、苏木、血竭、牡丹皮，适合血滞的情况。蒲黄、阿胶、地榆、百草霜、棕榈炭，适合血崩的情况。乳香、没药、五灵脂、凌霄花，适合血痛的情况。肉苁蓉、锁阳、牛膝、枸杞子、益母草、夏枯草、败龟板，适合血虚的情况。乳酪、动物血液等特类食物，适合血燥的情况。干姜、肉桂，适合血寒的情况。生地黄、苦参，适合血热的情况。这只是选取证治的大略而言，其余的可以触类旁通，由此推广。
君火，就是心火。可以用湿气伏住它，可以用水灭掉它，可以直接折损它，只有黄连这类药，可以制约它。相火，就是龙火，不可以用水去折损它。应当顺从其本性而伏藏它，只有黄柏这类药可以降伏它。唉！泻火的方法，难道只有这些吗？虚实情况多种多样，不可不仔细考察。从脏腑之气来主管，比如黄连泻心火，黄芩泻肺火，芍药泻脾火，石膏泻胃火，柴胡泻肝火，知母泻肾火，这些都是苦寒的味道能泻除有余的火邪。因饮食劳倦，内伤九气，与火不能两立，属于阳虚的病，用甘温的药剂来消除它，如黄芪、人参、甘草这类药。如果阴微阳强，相火炽盛，侵犯阴位，属于血虚的病，用甘寒的药剂来降伏它，如当归、地黄这类药。如果心火亢盛到了极点，郁热内实，属于阳强的病，用咸冷的药剂来折损它，如大黄、朴硝这类药。如果肾水受伤，真阴失守，无根之火，属于阴虚的病，用壮水的药剂来制约它，如生地黄、玄参这类药。如果有肾命门火衰，属于阳脱的病，用温热的药剂来济助它，如附子、干姜这类药。如果胃虚过食冷物，抑遏阳气于脾土，属于火郁的病，用升散的药剂来发散它，如升麻、干葛、柴胡、防风这类药。不明白诸如此类的道理，而去探求火之为病，施治有什么依据呢？所以在各经中收集略述这些说法，以备处方之用，或许可以避免实实虚虚（使实证更实，虚证更虚）的祸患。
Treatment of blood disorders involves the use of blood-tonifying herbs, such as those found in **Sì Wù Tāng** (Four Substances Decoction). Let us elaborate on the key aspects of their flavors and specific functions. **Chuān Xiōng** (Ligusticum Rhizome) is a Qi-moving herb within the blood category; it enters the Kidney Meridian. Its nature and flavor are sweet and cold [Note: Text says 'sweet and cold', though traditionally pungent and warm], capable of generating deficiency of true Yin. **Dāng Guī** (Angelica Sinensis Root) has three therapeutic applications and is the principal herb for blood; it enters the Liver Meridian. Its nature and flavor are pungent and warm, capable of invigorating blood and guiding it back to its respective meridians. **Sháo Yào** (Peony Root) is a Yin-category herb; it enters the Liver Meridian. Its nature and flavor is sour and cold, capable of harmonizing blood and treating abdominal pain due to blood deficiency. If one seeks herbs belonging to the Yin category, one must take this as the model. If practitioners adjust formulas according to the meridians, reducing or increasing one or two appropriate herbs, they can serve as the main treatment. This specifically discusses blood diseases and seeking herbs belonging to the blood category. However, if there is blood deficiency and weakness, one should follow the teachings of Changsha (Zhang Zhongjing), using **Rén Shēn** (Ginseng Root) to tonify; when Yang Qi is vigorous, Yin Blood is generated. If using **Sì Wù Tāng**, it solely addresses injuries to the blood aspect where Qi is not deficient. For auxiliary and assisting herbs, **Táo Rén** (Peach Seed), **Hóng Huā** (Carthamus Flower), **Sū Mù** (Sappan Wood), **Xuè Jié** (Dragon's Blood), and **Mǔ Dān Pí** (Tree Peony Bark) are suitable for blood stasis. **Pú Huáng** (Typha Pollen), **Ē Jiāo** (Donkey-Hide Gelatin), **Dì Yú** (Sedge Rhizome), **Bǎi Cǎo Shuāng** (Soot from Hundred Herbs), and **Zōng Lǘ Tàn** (Charred Palm Frond) are suitable for uterine bleeding. **Rǔ Xiāng** (Frankincense), **Mò Yào** (Myrrh), **Wǔ Líng Zhī** (Trogopterus Dung), and **Líng Xiāo Huā** (Campsis Flower) are suitable for blood-related pain. **Cōng Róng** (Cistanche Stem), **Suǒ Yáng** (Cynomorium Stem), **Niú Xī** (Achyranthes Root), **Gǒu Qǐ Zǐ** (Goji Berry), **Yì Mǔ Cǎo** (Motherwort Herb), **Xià Kū Cǎo** (Prunella Spike), and **Bài Guī Bǎn** (Tortoise Plastron Charred) are suitable for blood deficiency. Dairy products and animal bloods are suitable for blood dryness. **Gān Jiāng** (Dried Ginger Rhizome) and **Ròu Guì** (Cinnamon Bark) are suitable for blood cold. **Shēng Dì Huáng** (Rehmannia Root Prepared Fresh) and **Kǔ Shēn** (Sophora Root) are suitable for blood heat. These are merely general principles of syndrome differentiation and treatment; others can be understood by analogy.
The Ministerial Fire (Jun Huo) refers to Heart Fire. It can be subdued by dampness, extinguished by water, or directly reduced; only herbs like **Huáng Lián** (Coptis Rhizome) can control it. The Ministerial Fire (Xiang Huo) is Dragon Fire; it cannot be reduced by water. One should subdue it according to its nature; only herbs like **Huáng Bò** (Phellodendron Bark) can descend it. Alas! Are these the only methods to drain fire? There are numerous variations of excess and deficiency that must be carefully examined. Based on organ qi regulation: **Huáng Lián** drains Heart Fire, **Huáng Qín** (Scutellaria Root) drains Lung Fire, **Sháo Yào** drains Spleen Fire, **Shí Gāo** (Gypsum Fibrosum) drains Stomach Fire, **Chái Hú** (Bupleurum Root) drains Liver Fire, and **Zhī Mǔ** (Anemarrhena Rhizome) drains Kidney Fire. These are all bitter-cold flavors that drain excessive fire. Due to dietary irregularities and overwork, internal injury to the Nine Qi creates a conflict with fire, resulting in Yang deficiency diseases; these are treated with sweet-warm formulas, such as **Huáng Qí** (Astragalus Root), **Rén Shēn**, and **Gān Cǎo** (Licorice Root). If Yin is weak and Yang is strong, with rampant Ministerial Fire invading Yin positions, resulting in blood deficiency diseases, treat with sweet-cold formulas to descend fire, such as **Dāng Guī** and **Dì Huáng** (Rehmannia Root). If Heart Fire is extremely hyperactive with internal stagnant heat, resulting in Yang excess diseases, treat with salty-cold formulas to reduce fire, such as **Dà Huáng** (Rhubarb Root) and **Pǔ Xiāo** (Natrii Sulfas). If Kidney Water is injured and True Yin is lost, leading to rootless fire and Yin deficiency diseases, treat with formulas that strengthen water, such as **Shēng Dì Huáng** and **Xuán Shēn** (Scrophularia Root). If there is decline of Fire in the Kidney and Mingmen, resulting in Yang collapse diseases, treat with warm-hot formulas to assist Yang, such as **Fù Zǐ** (Aconite Root Prepared) and **Gān Jiāng**. If Stomach deficiency leads to excessive consumption of cold foods, suppressing Yang Qi in the Spleen Earth, resulting in depressed fire diseases, treat with ascending and dispersing formulas to vent the fire, such as **Shēng Má** (Cimicifuga Rhizome), **Gān Gě** (Kudzu Root), **Chái Hú**, and **Fáng Fēng** (Saposhnikovia Root). Without understanding these categories, how can one seek the pathology of fire and have a basis for treatment? Therefore, I have collected brief explanations from various meridians to prepare for prescription usage, hoping to avoid the disaster of reinforcing excess and depleting deficiency.
