无毒 石生
石中黄子久服轻身延年不老（名医所录）【地】（图经曰）本经不载所生州土云出禹余粮
处
有之今惟出河中府中条山谷内旧说是余粮壳中未成余粮黄浊水今云其石形如面剂紫黑色石皮
内黄色者谓之中黄据此两说小异今按抱朴子云石子中黄所在有之近水之山尤多在大石中其石
常润湿不燥打石石有数十重见之赤黄溶溶如鸡子之在壳得者即当饮之不尔便坚凝如石不中服
也破一石中多者有一升少者数合法当正及未坚时饮之其坚凝亦可末服也若然旧说是初破取者
今所用是久而坚凝者尔陶云芝品中有石中黄子非也（衍义曰）石中黄子此子字误也子当作水
况
当条自言未成余粮黄浊水焉得却名之子也若言未干者亦不得谓之子也子字乃水字无疑矣

无毒。生于石中。
石中黄子：长期服用可身体轻健、延年益寿、不老（名医所录）。【产地】（《图经本草》记载）《本经》未记载其生长的州土，只说出产于禹余粮处。现在只有河中府中条山的山谷内有出产。旧时说这是禹余粮食壳中尚未形成的禹余粮，呈黄浊水状；现在说这种石头形状像面剂，外皮紫黑色，内部黄色，称为“中黄”。根据这两种说法略有不同。现在考证《抱朴子》说石子中的黄水到处都有，靠近水的山中尤其多，在大石头中，这种石头经常湿润而不干燥，打石头时看到有几十层，里面的颜色赤黄溶溶，像鸡蛋在壳中一样。得到后应当立即饮用，否则就会坚凝如石头，不能服用了。破开一块石头，多的有一升，少的有几合。用法应当趁其未坚硬时饮用。如果已经坚凝，也可以研末服用。如果是这样，那么旧说是刚打破时取用的，而现在所用的是放置久了而坚凝的。陶弘景说《芝品》中有石中黄子，是不对的。（《衍义》说）石中黄子的“子”字是误写，“子”应当作“水”。况且文中自己说它是未成形的禹余粮黄浊水，怎么能又叫做“子”呢？如果说它未干，也不能称之为“子”。“子”字确实是“水”字无疑了。【采收时间】随时可生，随时可采。【药用部位】石中黄浊水。【颜色】黄色。【味道】甘。【性质】平缓。【气味属性】气薄，属于阳中之阴。【气味】朽味。【炮制】研细使用。
无名异：无毒。主治金疮折伤、内损，止痛，生肌肉（名医所录）。【产地】（《图经本草》记载）出产自大食国，生于石上，形状像黑石炭。番人用油炼制，像石头一样，嚼起来像饴糖。现在广州的山石中以及宜州南八里的龙济山中也有出产。其颜色黑褐，大的像弹丸。【颜色】黑褐色。【味道】甘。【性质】平缓。【气味属性】气薄，属于阳中之阴。【气味】朽味。【主要功效】续骨长肉。【治疗】（疗）（《图经本草》记载）消肿毒痈疣。
Non-toxic. Grows among stones.
Shizhong Huangzi (Yellow Mud from Stone): Long-term consumption lightens the body, prolongs life, and prevents aging (Recorded by Famous Physicians). 【Origin】(According to *Tujing Bencao*): The *Benjing* does not record the specific provinces or regions of origin, only stating it is found where Yuyuliang (Hematite) occurs. Currently, it is only produced in the valleys of Zhongtiao Mountain, Hezhong Prefecture. Old theories state this is the yellow turbid water within the shell of Yuyuliang that has not yet formed into Yuyuliang; current descriptions state that this stone resembles a dough cake, with a purple-black outer skin and a yellow interior, termed "Zhonghuang" (Middle Yellow). Based on these two accounts, there are slight differences. Current research based on *Baopuzi* states that the yellow water within stone fragments is available everywhere, especially abundant in mountains near water, within large rocks. These stones are often moist and not dry. When striking the stone, one may see dozens of layers; the color inside is reddish-yellow and fluid, resembling an egg within its shell. Upon obtaining it, one should drink it immediately; otherwise, it will harden like stone and become unfit for consumption. Breaking open a single stone yields more than one sheng (a unit of volume) or as few as several he (a smaller unit of volume). The method of use requires drinking it while it is not yet hardened. If it has already hardened, it can also be ground into powder and taken. If so, the old theory refers to taking it upon initial breaking, whereas what is currently used is that which has hardened after a long period. Tao Hongjing stated that Shizhong Huangzi appears in *Zhipin*, which is incorrect. (According to *Yanyi*): The character "Zi" (Son/Seed) in Shizhong Huangzi is an error; "Zi" should be read as "Shui" (Water). Moreover, the text itself describes it as the yellow turbid water of unformed Yuyuliang; how could it be named "Zi"? Even if referring to it being un-dried, it still cannot be called "Zi". The character "Zi" is undoubtedly a miswriting of "Shui". 【Harvest Time】Grows at any time; harvested at any time. 【Medicinal Part】Yellow turbid water from the stone. 【Color】Yellow. 【Taste】Sweet. 【Nature】Mild and balanced. 【Qi Property】Thin Qi, Yin within Yang. 【Odor】Rotten/Old odor. 【Processing】Ground into fine powder for use.
Wumingyi: Non-toxic. Mainly treats traumatic injuries from metal weapons, fractures, internal damage, relieves pain, and promotes muscle regeneration (Recorded by Famous Physicians). 【Origin】(According to *Tujing Bencao*): Originates from Da Shi Country (Arabia/Persia region), grows on stones, resembling black coal. Foreigners refine it with oil until it resembles stone, chewing it like maltose syrup. Currently, it is also found in the mountain rocks of Guangzhou and in Longji Mountain, eight li south of Yizhou. Its color is black-brown, with large pieces resembling bullet shots. 【Color】Black-brown. 【Taste】Sweet. 【Nature】Mild and balanced. 【Qi Property】Thin Qi, Yin within Yang. 【Odor】Rotten/Old odor. 【Main Efficacy】Reconnects bones and regenerates flesh. 【Treatment】(Therapy) (According to *Tujing Bencao*): Reduces swelling and detoxifies carbuncles and warts.
