水足以济火，故狂躁烦渴火实之证，内以水饮之，外以水渍之，此既济之妙，自《大易

甘梨浆，水类也。生之可平六腑之阳，熟之可济五脏之阴。实火宜生，虚火宜熟。
人屎人尿人中白牛屎猪屎马通驴子小便总考
孙思邈《千金方》凡疗火证、热证，率用上件取汁饮之，往往称其神良，何也？经曰∶
清阳出上窍，浊阴出下窍。屎溺出于二阴，则无分人类物类，皆阴浊也。惟其阴浊，故足以
制阳光。或者鄙而远之，由夫未达医之妙也。
古昔神良之医，但用人尿、溺白 耳，未尝有用秋石之方也，近时多用之。夫药有气有
味，有精有魄，秋石既经煎炼，则其气味已易，精华已去，所存者独枯魄耳，恶能与人尿、
溺白 论功效耶？此举世尚奇之昧也。或用阴秋石者为近之。
防风 川芎 川归 白芍药 大黄 芒硝 连翘 薄荷 麻黄 石膏 桔梗 黄芩 白
术栀子 荆芥 滑石 甘草
表里客热，三焦火实者，此方主之。
麻黄、防风，疏表药也，火热之在表者，得之由汗而泄；大黄、芒硝，攻里药也，火热
之在里者，得之由下而泄；荆芥、薄荷，清上药也，火热之在巅顶者，得之由鼻而泄；滑石、
栀
黄芩，又所以去诸经之客热也。火热灼其血，则川芎、当归、芍药可以养之；火热坏其气，
则白术、甘草可以益之。
叙曰：水与火，对应人体内的阴与阳。阳气常常偏盛，因此火证（由火热邪气引起的病证）往往较多，这就是所谓的“一水不胜五火”（阴液不足以制约亢盛的阳火）。人如果能够调理体内的火气，使其达到冲和（平和协调）的状态，就掌握了调和元气的关键。然而，如果过度使用寒凉药物，这又会产生弊端。自从有了五行学说以来，火是不可或缺的元素，因此知道将火完全熄灭是错误的做法。如今考察古代方剂二十余首来治疗火证，难道仅仅是为了灭火吗？
水足以济助火，所以对于狂躁、烦渴等实火证候，内服饮水，外用冷水浸渍，这是水火既济（阴阳平衡）的妙用，自《周易》以来，这种理念就已存在。
甘梨浆属于水性之物。生吃可以平抑六腑的阳气，煮熟食用可以济助五脏的阴液。实火适宜生吃，虚火适宜熟吃。
人屎、人尿、人中白、牛屎、猪屎、马通、驴子小便总考
孙思邈在《千金方》中记载，凡是治疗火证、热证，通常采用上述物质取汁饮用，往往称赞其神效良验，为什么呢？医经说：清阳之气出于上窍（眼耳口鼻），浊阴之气出于下窍（前后二阴）。屎溺从二阴排出，无论人类还是动物，都属于阴浊之物。正因为它们是阴浊的，所以足以制约亢盛的阳火（阳光）。有人轻视并远离这些药物，是因为他们未能通达医学的精妙之处。
古代那些医术高超的医生，只用人尿、溺白（人中白）罢了，从未有用秋石（从人尿中提炼的结晶物）的方剂，近代才多用秋石。药物具有气味，具有精气与形魄。秋石经过煎炼提取后，其气味已经改变，精华已经去除，所剩下的只有枯槁的形魄，怎么能与人尿、人中白的功效相提并论呢？这是世人崇尚新奇而导致的愚昧。如果使用未经提炼的阴秋石（指代类似人尿或原始提取物性质的材料，此处语境偏向于反对精制秋石，推崇天然排泄物或其简单处理品，但原文主要对比的是精制秋石与天然尿/白，故此处译为对未精制或天然属性的认可，或指代一种较原始的秋石制法，结合上下文“或用阴秋石者为近之”，意指接近天然属性者），那就比较接近真理了。
防风、川芎、当归（川归）、白芍药、大黄、芒硝、连翘、薄荷、麻黄、石膏、桔梗、黄芩、白术、栀子、荆芥、滑石、甘草。
对于表里俱有客热、三焦火实的病证，此方主治。
麻黄、防风，是疏解表邪的药物，体表的火热，借助它们通过发汗而泄出；大黄、芒硝，是攻逐里实的药物，体内的火热，借助它们通过泻下而泄出；荆芥、薄荷，是清利上焦的药物，巅顶部位的火热，借助它们通过宣散而从鼻窍泄出；滑石、栀子、黄芩，又是用来清除各经络中客居的热邪。火热灼伤血液，则川芎、当归、白芍药可以滋养血液；火热耗损正气，则白术、甘草可以补益正气。
Preface: Water and fire correspond to Yin and Yang in the human body. Yang Qi is often in excess, therefore Fire syndromes (diseases caused by pathogenic heat-fire) are frequently encountered. This is what is meant by "one water cannot overcome five fires" (Yin fluids are insufficient to restrain hyperactive Yang fire). If a person can regulate the internal fire, achieving a state of harmony and balance (Chonghe), they have mastered the art of harmonizing Yuan Qi (Primordial Qi). However, excessive use of cold and cooling remedies leads to adverse effects. Since the advent of the Five Elements theory, Fire has been indispensable; thus, knowing that extinguishing Fire completely is incorrect. Now, examining more than twenty ancient formulas for treating Fire syndromes, is it merely about extinguishing fire?
Water is sufficient to assist/restrain Fire. Therefore, for symptoms such as mania, restlessness, vexation, and thirst caused by Excess Fire, internal administration of water and external application of water immersion represent the wonderful effect of Water-Fire Ji Ji (Balance of Water and Fire/Yin-Yang equilibrium). This concept has existed since the *I Ching* (Book of Changes).
Sweet Pear Juice belongs to the category of Water. Consumed raw, it can pacify the Yang of the Six Fu organs; cooked, it can nourish the Yin of the Five Zang organs. Excess Fire is suitable for raw consumption, while Deficiency Fire is suitable for cooked consumption.
General Review of Human Feces, Human Urine, Ningzhongbai (Calcined Human Urine Sediment), Cow Dung, Pig Dung, Horse Manure, and Donkey Urine
Sun Simiao recorded in the *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) that when treating Fire or Heat syndromes, one generally uses the juices from the aforementioned substances for drinking, often praising their miraculous efficacy. Why? The Classics state: Clear Yang emerges from the upper orifices, and Turbid Yin emerges from the lower orifices. Feces and urine exit through the lower orifices; regardless of whether human or animal, they are all Yin-Turbid substances. Precisely because they are Yin-Turbid, they are sufficient to restrain hyperactive Yang Fire (Solar Light). Some people disdain and avoid these materials because they fail to comprehend the subtleties of medicine.
Ancient physicians with divine skills used only human urine and Ningzhongbai (Calcined Human Urine Sediment); they never used formulas containing Qiushi (Autumn Stone/Crystallized Human Urine Extract). It is only in recent times that Qiushi has been widely used. Medicines possess Qi (aroma/vital energy) and Wei (flavor), Jing (essence) and Po (corporeal soul). After Qiushi undergoes decoction and refinement, its Qi and Wei change, and its Jing essence is removed; what remains is merely a withered Po. How can it be compared in efficacy to human urine and Ningzhongbai? This reflects the ignorance of the world's tendency to pursue novelty. Using Yin Qiushi (referring to less refined or naturally oriented preparations, closer to the original nature) would be closer to the truth.
Fangfeng (Saposhnikovia Root), Chuanxiong (Ligusticum Chuanxiong Rhizome), Chuangui (Angelica Sinensis Radix), Baishaoyao (Paeoniae Radix Alba), Dahuang (Rhei Radix et Rhizoma), Mangxiao (Natrii Sulfas), Lianqiao (Forsythiae Fructus), Bohe (Menthae Haplocalycis Herba), Mahuang (Ephedrae Herba), Shigao (Gypsum Fibrosum), Jiegeng (Platycodonis Radix), Huangqin (Scutellariae Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Zhizi (Gardeniae Fructus), Jingjie (Schizonepetae Spica), Huashi (Talcum), Gancao (Glycyrrhizae Radix et Rhizoma).
This formula is indicated for conditions where pathogenic heat resides in both the exterior and interior, and there is Fire Excess in the Sanjiao (Triple Burner).
Mahuang and Fangfeng are herbs that release the exterior; for heat-fire residing in the exterior, they facilitate its discharge through sweating. Dahuang and Mangxiao are herbs that purge the interior; for heat-fire residing in the interior, they facilitate its discharge through defecation. Jingjie and Bohe are herbs that clear the Upper Jiao; for heat-fire at the vertex, they facilitate its discharge via the nasal orifices. Huashi, Zhizi, and Huangqin serve to eliminate pathogenic heat from various meridians. When heat-fire scorches the Blood, Chuanxiong, Danggui (Angelicae Sinensis Radix), and Shaoyao (Paeoniae Radix) can nourish it; when heat-fire damages the Qi, Baizhu and Gancao can tonify it.
