琅玕（一种似玉的美石）
味辛，气寒，无毒。产于日本国，生于玉石之间。品种有三类：红色、黑色和白色。纹理如缠丝状的均为上品，用木头研磨不发热者才是真品。（若用木头研磨发热则不是真品。）当地人得到它后，将其碾磨成玩赏器物。虽然被视为重宝，也用于医疗方剂中。可辟除邪恶精气，熨敷治疗目赤溃烂。琉璃是火炼而成的物品，眼睛发红也可用水浸泡后熨敷治疗。玻璃即水精珠，像玉一样极其光亮晶莹的。能安心明目，每每显现奇特功效。夜晚面向太阴（月亮），可以取得真水。用火精取火，（面向太阳即可取得。）名称不同但实质相同。又有一种珊瑚只生长在海底。海船沉下铁网挂取，红润且多枝柯参差不齐。长的有一丈多，短的有一尺左右。中间有很多细孔，刺破则有汁液流出。投入金中化为金浆，投入玉中化为玉髓。饮用的人，可以达到长生。折断枝条研成粉霜，点入眼中拂去眼翳。吹入鼻中以治鼻塞和鼻衄，能镇心安神止惊。仍治疗风痫，更主治消渴症。琅玕也生长在海底，枝柯与珊瑚大致相同。航海者想要寻求，必须使用铁网。出水时红润，久置旋转后变青。枝条敲击有金石之声，药剂使用时可以煮汁服用。克制锡毒畏惧鸡骨，号称青珠（古人将美丽的石头称为珠，黄金也称为珠。《广雅》称琉璃、珊瑚都称为珠就是此意。）适宜得水银配合。主治皮肤浸淫死肌，去除身体瘙痒疮疥。除去石淋并破除恶血，升起阴气可化为丹砂。还有贝类，形状像蚌蛤。外部多有纹理，也出产于海中。得到的人珍藏起来，不辱没玉石之名。能安神镇宅，解毒杀虫。《西域记》说：重重殿堂的梁柱，都用七宝装饰，这就是其中之一。

Coral
Langgan (a gemstone resembling jade)
Pungent in flavor, cold in nature, non-toxic. Originates from the country of Japan, growing among jade stones. There are three varieties: red, black, and white. Those with patterns like twisted silk are all excellent; those that do not generate heat when rubbed against wood are genuine. (If heat is generated when rubbed against wood, it is not genuine.) Locals obtain them and grind them into ornamental objects. Although regarded as precious treasures, they are also used in medical prescriptions. They can ward off evil spirits and malign influences, and are applied hot to treat redness and ulceration of the eyes. Liuli (colored glaze/glass) is a substance formed by fire; for red eyes, it can also be soaked in water and applied as a compress. Bolu (glass/crystal) is the crystal pearl, resembling jade but extremely bright and lustrous. It calms the mind and improves vision, often achieving remarkable results. Facing the Moon at night, one can obtain "true water." Using Huojing (fire crystal) to extract fire (by facing the Sun), though names differ, the essence is the same. Another type of coral grows only at the bottom of the sea. Fishing boats sink iron nets to catch them; they are reddish-brown with many branches of uneven length. Long ones may exceed one zhang, while short ones are about one chi. They have many fine pores inside, and juice flows out when pierced. When gold is thrown in, it becomes golden paste; when jade is thrown in, it becomes jade marrow. Those who drink it may attain longevity. Broken branches ground into powder can be applied to the eyes to remove film-like obstructions. Blown into the nose to treat nasal congestion and epistaxis, it calms the heart and stops fright. It also treats wind-induced epilepsy and primarily manages xiaoke (wasting-thirst syndrome). Langgan also grows at the bottom of the sea, with branches similar to coral. Sailors seeking it must use iron nets. When brought out of water, it is reddish-brown, but turns green after prolonged exposure or rotation. Striking the branches produces a metallic sound; for medicinal use, it can be boiled to make a decoction. To counteract tin toxicity, chicken bone is feared/used; it is known as Qingzhu (Green Pearl). (Ancients referred to beautiful stones as pearls, and even gold was called a pearl. The *Guangya* states that liuli and coral are both called pearls.) It is suitable to be combined with mercury. It treats skin infiltration and necrotic tissue, removes body itching, sores, and scabies. It eliminates stone lin (lithiasis) and breaks up stagnant blood, raises yin qi, and can be transformed into cinnabar. There are also shells, shaped like clams. They have many textures on the outside and also come from the sea. Those who find them treasure them, not disgracing the status of jade and stone. They calm the spirit and protect the residence, detoxify, and kill parasites. The *Records of the Western Regions* states: "The beams and pillars of grand halls and temples are all decorated with the Seven Treasures; this is one of them."
