【性味与产地】无毒。生长于土石之中。
曾青（出自《神农本草经》）：主治目痛，止泪出，治疗风痹，通利关节，疏通九窍，破除症坚积聚。长期服用可轻身不老，能化金铜。
（以上朱字部分为《神农本草经》原文）：滋养肝胆，除寒热，杀白虫，治疗头风、脑中寒，止烦渴，补不足，盛阴气。
（以上黑字部分为名医所录）
【地】（《图经》记载）：产于益州山谷及越西山有铜的地方，因铜精熏蒸而生。如今信州也有出产。其疗效与空青颇为相似，颜色和纹理也几乎无异，但其形状累累相连如连珠相缀，现在极难获得。（《唐本草注》云）蔚州的品质最好，其次是鄂州，其余各州产出的均不适用。
【时】（采集时间）：无固定时节。
【用】：无夹杂石头的为佳。
【质】：质地类似蝉腹，且呈连珠相缀状。
【色】：土黄色。
【味】：酸。
【性】：微寒。
收【气】：气味浓于气阴。
【主】：主治目痛，爽神气。
【反】：畏菟丝子。
【制】（雷公云）：凡是炮制二两曾青，需用紫背天葵、甘草、青芝草三味药，干湿各一镒，一同细锉后放入一个瓷埚内。将曾青置于其中，加入东流水二镒及上述诸药等量，缓缓煮之五昼夜，不要令水火失时。足时取出，用东流水冲洗，然后放入乳钵内研成粉末使用。
车渠：《集韵》云：产于西国，是玉石之类，形状似蚌蛤，有文理。大寒，无毒。主治安神镇宅，解诸毒药及虫螫。以玳瑁一片与车渠等同用人乳磨服，极有效验。又《西域记》云：重堂殿梁檐皆以七宝饰之，此其一也。
○ 金线矾广：《广州志》云：产于波斯国，味咸酸涩，有毒。主治野鸡痔、恶疮、疥癣等疾。打破内有金线纹者为上品，多入烧家用。
○ 波斯白矾：《广州记》云：出自大秦国，其色白而莹净，内有棘针纹，味酸涩，温，无毒。主治赤白漏下、阴蚀、泄痢、疮疥，解一切虫蛇等毒，去目赤暴肿、齿痛。火炼之良。恶牡蛎。多入丹灶家，功力逾于河西石门者。近日文州诸番往往亦有可用也。
[Properties and Origin] Non-toxic. Grows in earth and stones.
Cengqing (Zhuqing, Malachite) [Source: *Shennong Bencao Jing*]: Indicated for eye pain, stops tearing, treats wind-bi syndrome, unblocks joints, opens the nine orifices, breaks up masses and accumulations. Long-term use lightens the body and prevents aging; can transform gold and copper.
(Above red text is from *Shennong Bencao Jing*): Nourishes the liver and gallbladder, eliminates chills and fever, kills white parasites, treats cephalalgia and cold in the brain, stops irritability and thirst, tonifies deficiency, and strengthens Yin qi.
(Above black text is recorded by famous physicians)
[Geography] (*Tu Jing* records): Produced in the valleys of Yizhou and the western mountains of Yue where copper exists, generated by the fumes of copper essence. Currently also produced in Xinzhou. Its therapeutic effect is quite similar to Kongqing (Azurite), and its color and texture are almost indistinguishable, but its shape is clustered like linked pearls, which is now extremely rare. (*Tang Ben Cao Zhu* states): The best quality comes from Weizhou, followed by Ezhou; those from other prefectures are not suitable for use.
[Time] (Harvesting): No fixed season.
[Usage]: Those without stone impurities are superior.
[Texture]: Resembles cicada wings and is clustered like linked pearls.
[Color]: Earthy yellow.
[Taste]: Sour.
[Nature]: Slightly cold.
[Aroma/Qi]: The aroma/taste is stronger than the Qi/Yin aspect.
[Indications]: Treats eye pain, refreshes the spirit and Qi.
[Antagonism]: Feared by Tusizi (Cuscutae Semen).
[Processing] (Lei Gong says): When processing two liang of Cengqing, use three herbs: Zibeitiankui (Basella rubra), Gancao (Glycyrrhizae Radix et Rhizoma), and Qingzhicao (Poria with Hostwood? Note: Qingzhi usually refers to a specific mushroom/herb, here kept as Qingzhi Cao), each one yi (ancient weight unit) dry or wet. Finely chop them together and place in a porcelain crucible. Put the Cengqing inside, add two yi of East-flowing water and equal amounts of the other herbs. Simmer slowly for five days and nights, ensuring the fire and water do not lose their proper timing. Remove when sufficient, rinse with East-flowing water, then grind into powder using a mortar and pestle.
Chequ (Conch Shell/Chank Shell): *Jiyun* states: Produced in Western countries, it is a type of jade/stone, resembling clam shells with grain patterns. Very cold, non-toxic. Indicates for calming the spirit, stabilizing the residence, resolving various poisons and insect stings. Grinding one piece of Dai Mao (Trionycis Carapax) together with Chequ in human milk for administration is highly effective. Also, *Xiyu Ji* states: Heavy halls and temple beams are decorated with the Seven Treasures, this is one of them.
○ Jinxian Fan (Gold-thread Alum): *Guangzhou Zhi* states: Produced in Persia, taste is salty, sour, and astringent, toxic. Indicates for wild chicken hemorrhoids, malignant sores, scabies, and tinea. Breaking it open reveals gold-thread patterns; those with such patterns are superior grade, mostly used in alchemical firing.
○ Bosi Bai Fan (Persian White Alum): *Guangzhou Ji* states: Comes from Daqin (Rome/Byzantium), color is white and translucent/clear, with thorn-like needle patterns inside. Taste is sour and astringent, warm, non-toxic. Indicates for red and white leukorrhea, genital erosion, diarrhea and dysentery, sores and scabies; resolves all insect and snake toxins; reduces acute redness and swelling of the eyes and toothache. Calcining by fire is good. Antagonistic to Emu Li (Ostreae Concha). Mostly used by alchemists; its efficacy surpasses that from Shimen in Hexi. Recently, various tribes in Wenzhou also produce usable quantities.
