太乙禹余粮，文已具禹余粮条下。
\r无名异\ph20.bmp\r，出大食国，生于石上，今广州山石中及宜州南八里龙济山中亦
有之。黑褐色，大者
如弹丸，小者如墨石子，采无时。《本经》云∶味甘，平。主金疮折伤内损，生肌肉。今云
味咸，寒。消肿毒痈疣，与《本经》所说不同，疑别是一种。又岭南人云∶有石无名异，绝
难得。有草无名异，彼人不甚贵重。岂《本经》说者为石，而今所有者为草乎？用时以醋磨
涂敷所苦处。又有婆娑石，生南海，解一切毒。其石绿色，无斑点，有金星，磨之成乳汁者
为上。胡人尤珍贵之，以金装饰作指驱带之。每欲食及食罢，辄含吮数四，以防毒。今人有
得指面许块，则价值百金。人莫能辨，但水磨涓滴，点鸡冠热血，当化成水，乃真也。俗谓
之摩娑石。
\r石中黄子\ph22.bmp\r，《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。两说小
异，谨按葛洪《抱朴子》云∶石中黄子所在有之，近水之山尤多，在大石中，其石常润湿不
燥，打石，石中有数十重，见之赤黄，溶溶如鸡子之在壳，得者即当饮之，不尔便坚凝成石
，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，即坚凝，亦可末
服也。若然旧说，是初破取者。今所用，是久而坚凝者耳。采无时。
太乙禹余粮，其详细记载已在“禹余粮”条目下说明。
无名异，产自大食国（古代阿拉伯地区），生长于岩石之上，如今在广州的山石中以及宜州南面八里的龙济山中也有出产。颜色为黑褐色，大的像弹丸，小的像墨石子，采集没有固定时间。《神农本草经》记载：味甘，性平。主治金创折伤及内部损伤，促进肌肉生长。现在说法是味咸，性寒。能消肿毒、痈疽和疣赘，这与《神农本草经》所述不同，怀疑是另一种药材。另外岭南人说：有一种石头叫无名异，极其难得；还有一种草也叫无名异，当地人并不十分看重。难道《神农本草经》所说的是石头，而现在拥有的是草吗？使用时用醋研磨后涂抹敷在患处。还有婆娑石，产于南海，能解一切毒。这种石头呈绿色，无斑点，带有金星，研磨后能变成乳汁状的是上品。胡人尤其珍视它，用黄金装饰做成指环佩戴。每次想要进食或进食完毕后，就含吮几次，以防中毒。现在有人得到指甲盖大小的一块，价值百金。人们无法辨别真假，只有用水研磨出几滴，点在公鸡冠的新鲜热血上，如果化成水，才是真品。俗称摩娑石。
石中黄子，《神农本草经》未记载其产地，说在禹余粮出产的地方有之。如今只产于河中府中条山的山谷内。旧说是禹余粮壳中尚未凝结成禹余粮的黄色浑浊水。现在说这种石头形状像面团剂子，外皮紫黑色，里面黄色，称为中黄。两种说法略有差异，谨按葛洪《抱朴子》记载：石中黄子所在之处都有，靠近水源的山上尤其多，存在于大石头中，这些石头常常湿润而不干燥，敲击石头，石头中有几十层，见到赤黄色，溶溶如鸡蛋在壳中，得到的人应当立即饮用，否则就会坚凝成石头，不能服用。打破一块石头，多的有一升，少的有几合，方法应当是在尚未坚硬时饮用，一旦坚硬凝固，也可以磨粉服用。如果是这样，旧说指的是刚打破时取用的。现在所用的，是放置久而坚硬凝固的罢了。采集没有固定时间。
Taiyi Yuyuliang (Taiyi Hematite), its detailed description has already been provided under the entry for Yuyuliang (Hematitum).
Wumingyi (Pyrolusite), originates from Dasiguo (ancient Arab region), grows on rocks. It is now also found in the rocky mountains of Guangzhou and in Longji Mountain, eight li south of Yizhou. It is dark brown; large pieces are like bullet shots, small ones like ink stones. It can be harvested at any time. *Shennong Bencao Jing* (Divine Farmer's Materia Medica) states: Sweet in taste, neutral in nature. It treats traumatic injuries from metal weapons, fractures, internal damage, and promotes muscle regeneration. Current descriptions state it is salty in taste and cold in nature. It reduces swelling, detoxifies carbuncles, sores, and warts. This differs from the description in *Shennong Bencao Jing*, leading to suspicion that it might be a different substance. Additionally, people in Lingnan say there is a stone called Wumingyi, which is extremely rare, and a herb also called Wumingyi, which locals do not value highly. Could it be that the *Shennong Bencao Jing* refers to the stone, while what is currently available is the herb? When used, it is ground with vinegar and applied topically to the affected area. There is also Posuo Shi (Posuo Stone), produced in the South Sea, capable of resolving all toxins. The stone is green, without spots, contains golden flecks, and yields a milky liquid when ground; this is considered superior. Hu people (people from Central/West Asia) particularly treasure it, decorating it with gold to wear as finger rings. Before eating or after finishing a meal, they hold it in their mouth and suck on it several times to prevent poisoning. Currently, a piece the size of a fingernail is worth a hundred taels of gold. People cannot distinguish authenticity easily; only when water-ground drops are placed on fresh blood from a rooster's comb and dissolve into water is it genuine. Commonly known as Mosuo Shi.
Posuo Shi, see details under the entry for Wumingyi.
Shizhonghuangzi (Yellow Substances within Stones), *Shennong Bencao Jing* does not record its origin, stating it is found where Yuyuliang (Hematite) is produced. Currently, it is only found in the valleys of Zhongtiao Mountain, Hezhong Prefecture. The old theory suggests it is the yellow turbid water inside the shell of Yuyuliang before it solidifies into Yuyuliang. The current description states the stone resembles dough pellets, with a purple-black outer skin and a yellow interior, termed "Zhonghuang" (Middle Yellow). The two theories differ slightly. According to Ge Hong's *Baopuzi*: Shizhonghuangzi exists wherever it is found, especially abundant in mountains near water, residing within large rocks. These rocks are often moist and not dry. When struck, dozens of layers are revealed within the rock, showing a reddish-yellow color, fluid-like an egg yolk within a shell. Those who obtain it should drink it immediately; otherwise, it will harden into stone and become unfit for consumption. Breaking one stone may yield up to one sheng (approx. 1 liter) or as little as a few he (approx. 0.2 liters). The method dictates drinking it while it is still unhardened; once hardened, it can be powdered and taken orally. If so, the old theory refers to the substance obtained upon initial breaking. What is currently used is the substance that has hardened over time. It can be harvested at any time.
