【代赭】
味道咸，没有毒性。主治妇女外阴溃烂、高热、干燥结痂。生长在高山悬崖背阴处，颜色白如油脂，采集时间不限。
这种药石类似于钟乳石、孔公孽等，所以也有“孽”这个名称，只是生长在悬崖上罢了，现在虽然有，但不再被采用。
〔谨案〕这就是土乳。产于渭州鄣县三交驿西北坡平地的土窟中，可以看到有六十多个坑穴是前人开采过的地方。当地人说：陶弘景和《神农本草经》都说它长在崖上，这种说法是不对的。现在渭州也不再采用这种药材了。
【代赭（另一条记载）】
味道苦、甘，性寒，没有毒性。主治鬼疰（一种慢性消耗性疾病）、贼风（突然袭来的邪风）、蛊毒，能杀死精怪恶鬼，消除腹中的中毒邪气；治疗女子赤白带下淋漓不断、带脉出血、堕胎；能养血气，清除五脏血脉中的热邪、血痹、血瘀；治疗大人小儿惊气入腹以及阳痿不起。
别名须丸。出产在姑幕的称为须丸，出产在代郡的称为代赭，又名血师。生长于齐国的山谷中，颜色呈赤红青色，像鸡冠一样有光泽，能染指甲且不褪色的为佳品，采集时间不限。
畏忌天雄。旧时说它是代郡城门下的泥土。江东地区早已断绝来源，近来魏国所献上的，仍然是那里的赤土，不再是真正的药材，这在世俗应用中已经疏略，却是炼丹方剂中的重要药物，与戎盐、卤咸等都是急需之物。
〔谨案〕这种石头大多从代州运来，说是山中采得的，并非城门下的泥土，又说生长于齐、代两地的山谷。现在齐州亭山出产赤石，颜色有赤红青色的。其中红色的，也像鸡冠一样润泽，当地人只采集它来涂饰柱子，而紫色的则色泽暗淡。这种物品与代州出产的相似，自古以来就被使用。现在灵州鸣沙县界内的黄河边，平地挖掘深四、五尺所得到的，表皮赤滑，中间紫色如鸡肝，远胜于齐州、代州所产的。
[Dai Zhe]
Salty in taste, non-toxic. It primarily treats women's genital erosion (ulceration of the external genitalia), high fever, and dry scabs. It grows on the shady slopes of high mountain cliffs, with a color white like fat. It can be harvested at any time.
This mineral resembles Zhongru Shi (Stalactite) and Konggong Nie, hence it also bears the name "Nie," but it is found on cliffs. Although it exists today, it is no longer commonly used.
[Note] This is indeed Tu Ru (Earth Milk). It is produced in earthen caves on flat ground northwest of Sanjiao Post Station, Zhang County, Weizhou. There are over sixty pits visible where ancestors once mined it. Locals state that Tao Hongjing and the *Shennong Bencao Jing* both claim it grows on cliffs, which is incorrect. Currently, it is not adopted in Weizhou.
[Dai Zhe (Alternative Record)]
Bitter and sweet in taste, cold in nature, non-toxic. It treats Gui Zhu (ghostly pestilence/chronic wasting disease), Zei Feng (sudden pathogenic winds), Gu Du (gu poison), and evil spirits; it eliminates toxic pathogens in the abdomen; it treats women's leukorrhea with bleeding (Chi Wo Lou Xia), vaginal discharge from the Dai Mai (Girdle Vessel), miscarriage; it nourishes blood and qi, clears heat from the blood vessels of the five zang organs, resolves blood bi (painful obstruction due to blood stasis) and blood stasis; it treats adults and children suffering from fright qi entering the abdomen, and impotence.
Also known as Xu Wan. Those originating from Gumu are called Xu Wan; those from Dai Commandery are called Dai Zhe; another name is Xue Shi. It grows in the valleys of Qi State. The best quality is red, crimson, and bluish-green, glossy like a rooster's comb, capable of staining fingernails without fading. It can be harvested at any time.
It is incompatible with Tianxiong (Aconiti Lateralis Radix Preparata). Old theories claimed it was soil from under the city gates of Dai Commandery. Sources in Jiangdong have long been exhausted. Recent offerings from the Wei Kingdom were merely local red earth, not the true substance. While its use in secular medicine has declined, it remains a crucial ingredient in alchemical formulas, alongside Rong Yan (Salpetrae Crystallizatum) and Lu Xian (Halitum), all of which are urgently needed.
[Note] This stone mostly comes from Daizhou, said to be mined from mountains, not soil from under city gates, nor does it grow in the valleys of Qi and Dai as previously stated. Currently, Chizhou Ting Mountain produces red stones with red, crimson, and bluish-green hues. The red ones are glossy like a rooster's comb; locals only mine them to paint pillars, while the purple ones are dull. This substance resembles that from Daizhou and has been used since ancient times. Now, in Mingsha County, Lingzhou, along the Yellow River, digging four or five chi deep in flat land yields stones with a smooth red surface and a purple interior like chicken liver, which far surpasses those from Qizhou and Daizhou.
