\r青琅 \ph51.bmp\r，生蜀郡平泽。苏恭注云∶琅 乃有数种，是琉璃之类，火齐宝
也。琅 五色具
，以青者入药为胜，出 （音髓）州以西乌白蛮中及于阗国也。今秘书中有《异鱼图》，载
琅
有孔窍如虫蛀，击之有金石之声，乃与珊瑚相类。其说不同，人莫能的识。谨按《尚书禹贡
》∶雍州厥贡， 、琳、琅 。《尔雅》云∶西北之美者，有昆仑之 、琳、琅 焉。孔
安国、郭璞皆以为石之似珠者，而《山海经》云∶昆仑山有琅 。若然是石之美者，明莹
若珠之色，而其状森植耳。大抵古人谓石之美者，多谓之珠。《广雅》谓琉璃、珊瑚，皆为
珠是也。故《本经》一名青珠，而左太冲《蜀都赋》云∶青珠黄环。黄环是木，然引以相并
者，亦谓其美如珠，而其类实木也。又如上所说，皆出西北山中，而今图乃云海底得之。盖
珍瑰之物，山、海、谷俱产焉。今医方家亦以难得而稀用也。
石蛇，出产于南海水边的山石之间。它的形状盘曲如同蛇一样，没有头尾，内部中空，颜色为红紫色，又像是车螺（一种海螺），不知道是由什么物体变化而来的。大体上与石蟹属于同类，药用功效也相近，尤其能够解除金石类药物引起的毒性。左边盘绕的质地较好。采集没有固定的时间。味道咸，性质平和，无毒。
黑羊石，生长在兖州宫山的西侧。味道淡，性质热，能解药物之毒。在春季挖掘土地采集，以黑色且有墙壁般光泽莹润的为上品。
白羊石，生长在兖州白羊山。味道淡，其性质：熟用则大热，生用则凉，能解各种药物之毒。在春季挖掘土地采集，以白色晶莹的为良材。
青琅玕，生长在蜀郡的平泽之地。苏恭注释说：琅玕有好几种，是琉璃之类的，属于火齐宝（一种宝石）。琅玕五色俱全，其中以青色入药效果最佳，产自髓州以西的乌白蛮地区以及于阗国。如今秘书省中有《异鱼图》，记载琅玕有孔窍像被虫蛀过一样，敲击时有金石的声音，这与珊瑚相似。说法不同，人们不能确切识别。谨按《尚书·禹贡》记载：雍州的进贡物品中有瑊、琳、琅玕。《尔雅》说：西北方的美好之物，有昆仑山的瑊、琳、琅玕。孔安国、郭璞都认为这是像珠子的石头，而《山海经》说：昆仑山有琅玕。如果是这样，那就是美丽的石头，明莹如珠子的色泽，而且形态森然直立。大体上古人称美丽的石头，多称之为珠。《广雅》称琉璃、珊瑚都称为珠，就是这样的道理。所以《神农本草经》中它有一个名字叫青珠，而左思的《蜀都赋》说：青珠黄环。黄环是树木，但引用它与青珠并列，也是因为认为它美如珠子，且其类同实木。又如上面所说，都出产于西北山中，而现在的图谱却说从海底获得。大概珍奇瑰丽的物品，山、海、山谷都有产出。如今医方家中也因为难得而很少使用。
Shishe (Stone Snake), found among the rocks near the sea in the South Sea. Its shape is coiled like a snake, without head or tail, hollow inside, red-purple in color, and resembles a charuo (a type of conch shell); it is unknown what substance transformed into it. Generally, it is of the same category as Shixie (Stone Crab), with similar medicinal functions, especially capable of resolving toxicity from mineral drugs. Those coiling to the left are considered superior. It can be collected at any time. Flavor: salty; Nature: neutral; Non-toxic.
Heiyangshi (Black Sheep Stone), grows on the west side of Gongshan in Yanzhou. Flavor: bland; Nature: hot; resolves drug toxicity. It is dug up from the ground in spring. The best quality is black with a glossy, wall-like luster.
Baiyangshi (White Sheep Stone), grows on Baiyang Mountain in Yanzhou. Flavor: bland; its nature is such that when processed (cooked), it becomes extremely hot, while raw use makes it cool; it resolves toxicity from various drugs. It is dug up from the ground in spring. The best quality is white and crystalline.
Qinglanggan (Green Langgan), grows in the flat marshes of Shujun. Su Gong annotated: Langgan comes in several varieties; it belongs to the category of liuli (glaze/glass) and is a Huoji Bao (fire-tempered treasure). Langgan possesses five colors, with the green variety being the most effective for medicinal use. It originates from the Wubai Man regions west of Sui Province and the Kingdom of Khotan. Currently, the "Yi Yu Tu" (Illustrated Rare Fish) in the Secretariat records that Langgan has holes resembling insect borings and produces a metallic sound when struck, resembling coral. Due to differing descriptions, people cannot definitively identify it. According to the "Yu Gong" chapter of the "Book of Documents": Yongzhou's tribute includes Jian, Lin, and Langgan. The "Erya" states: Among the beauties of the northwest are the Jian, Lin, and Langgan of Kunlun Mountain. Kong Anguo and Guo Pu both regarded them as stones resembling pearls. The "Classic of Mountains and Seas" states: Kunlun Mountain has Langgan. If so, these are beautiful stones, bright and clear like pearls, with an upright, dense growth habit. Generally, ancients referred to beautiful stones as pearls. The "Guangya" states that liuli and coral are also called pearls, which explains this. Thus, the "Shennong Bencao Jing" lists one of its names as Qingzhu (Green Pearl), and Zuo Si's "Shudu Fu" mentions: "Qingzhu and Huanghuan." Huanghuan is a tree, but it is cited alongside Qingzhu because it is considered beautiful like a pearl and shares similarities with solid wood. As mentioned above, these items originate from mountains in the northwest, whereas current illustrations claim they are obtained from the seabed. Presumably, rare and precious objects are produced in mountains, seas, and valleys alike. Today, medical practitioners rarely use it due to its scarcity.
