姜石，所在皆有。须不见日色旋取，微白者佳。治疔肿殊效。
有人饲折翅雁，后遂飞去。今人打扑损，研极细，水飞过，同当归、没药各半钱，
以酒调，频服，仍以手摩痛处。
今人用者如蚬蛤之状，色如土，坚重则石也。既无羽翼，焉能自石穴中飞出，何故只
堕沙滩上？此说近妄。《唐本》注∶永州土岗上掘深丈余取之，形似坩而小，重如石。则此
自是一物，余说不可取。溃、虚、积药中多用。
疟家或用，才过剂，则吐泻兼作，须浓研绿豆汁，仍兼冷水饮，得石脑油即伏。今信
州凿坑井，下取之。其坑常封锁，坑中有浊绿水，先绞水尽，然后下凿取。生砒谓之砒黄，
其色如牛肉，或有淡白路，谓石非石，谓土非土，磨研酒饮，治癖积气有功。才见火，便有
毒，不可造次服也。取砒之法∶将生砒就置火上，以器覆之，令砒烟上飞着覆器，遂凝结，
累然下垂如乳，尖长者为胜，平短者次之。《图经》言大块者。其大块者已是下等，片如细
屑者极下也。入药当用如乳尖长者，直须详谨。
水飞，治目中翳。今皮作家用之，磨皮上垢，无出此石。石蟹条中云∶浮石，平，无
毒，止渴，治淋，杀野兽毒，合于此条收入。
治大风疾。别有法，须烧用。金星石于苍石内，外有金色麸片。银星石，
有如银色麸片。又一种深青色，坚润，中有金色如麸片，不入药，工人碾为器，或妇人首饰
。余如经。
姜石，各地都有出产。必须是在不见阳光的情况下随即采挖，颜色微白的品质最佳。治疗疔疮肿毒有显著疗效。
有人曾饲养一只折断了翅膀的大雁，后来大雁竟然飞走了。现在人们如果遭受跌打损伤，将姜石研磨得极细，用水飞法处理，与当归、没药各半钱（约1.5克），用酒调匀，频繁服用，同时用手按摩疼痛部位。
现在人使用的姜石形状像蚬蛤，颜色像泥土，质地坚硬沉重则是石头。既然没有羽毛翅膀，怎么能从石穴中飞出呢？为什么只会掉落在沙滩上？这种说法接近荒谬。《新修本草》注解说：在永州的土岗上挖掘一丈多深才能取到，形状像小缸但较小，重量像石头。那么这自然是另一种东西，其他的说法不可采信。姜石在溃积类药物中应用较多。
疟疾患者有时也会使用姜石，但如果稍微超过剂量，就会引起呕吐和腹泻同时发作，此时必须浓磨绿豆汁，并配合饮用冷水，若能得到石脑油则能平息毒性。现在信州地区开凿坑井来开采它。这些坑通常被封锁，坑中有浑浊的绿水，先要把水绞干，然后下去开凿采集。生砒被称为“砒黄”，其颜色像牛肉，或者有淡白色的纹路，说它不是石头也不是泥土，研磨后用酒送服，对治疗癖积之气有效。一旦见到火，就会产生毒性，不可轻易服用。取砒的方法：将生砒放在火上，用器皿覆盖在上面，让砒烟上升附着在覆盖的器皿上，于是凝结成块，层层下垂像乳汁一样，尖端细长者为上品，平短者为次品。《图经本草》说的是大块状的。那些大块状的已经是下等货，片状如细屑的更是极下等。入药应当使用像乳汁尖端细长的，务必详细谨慎。
水飞法处理的姜石，可治疗眼目中的翳障。现在皮匠也使用它，用来磨除皮上的污垢，没有比这更好的石头了。《本草衍义·石蟹条》中提到：浮石，性平，无毒，止渴，治疗淋证，杀灭野兽毒素，应合并收录在此条中。
治疗大风疾（麻风病）。另有方法，必须烧制后使用。金星石存在于苍石内部，外部有金色的麸片状物质。银星石，有如银色麸片状的物质。又有一种深青色，质地坚硬润泽，中间有金色如麸片状的物质，不入药，工匠将其碾磨制成器物，或作为妇女的首饰。其余内容如经典记载。
Jiangshi (Rhizolith), is available everywhere. It must be dug up immediately without exposure to sunlight; those with a slightly white color are of the best quality. It has remarkable efficacy in treating dingzhong (carbuncles and sores).
There is a story that someone raised a wild goose with a broken wing, which later flew away. Nowadays, when people suffer from contusions or injuries due to falls or blows, Jiangshi is ground into an extremely fine powder, processed by water levigation (shuifei), and mixed with equal parts (half qian, approx. 1.5g) of Danggui (Angelica sinensis) and Moyao (Myrrha). The mixture is taken frequently with wine, accompanied by manual massage of the painful area.
The Jiangshi used today resembles clams or cockles in shape, has a soil-like color, and if hard and heavy, it is stone. Since it lacks feathers and wings, how could it fly out from a stone cave? Why would it only fall onto sandy beaches? This explanation is close to absurdity. The commentary in *Xinxiu Bencao* states: "It is dug from earthen ridges in Yongzhou at a depth of more than one zhang (approx. 3 meters); its shape resembles a small jar but is smaller, and it is as heavy as stone." Thus, this is naturally a different substance, and other descriptions should not be accepted. Jiangshi is frequently used in formulations for resolving accumulations.
Patients with nue (malaria) sometimes use Jiangshi. If the dosage is exceeded even slightly, vomiting and diarrhea occur simultaneously. In such cases, a concentrated decoction of Lüdou (Mung Bean) must be prepared, and cold water should be drunk concurrently. If Shinao You (naphtha/mineral oil) is obtained, the toxicity can be subdued. Currently, in Xinzhou, pits and wells are dug to extract it. These pits are usually sealed; they contain turbid green water. The water is first drained, and then excavation takes place underground. Raw Piyin (Realgar/Orpiment derivative known as 'Pi Huang') has a color resembling beef, sometimes with pale white veins. It is described as neither stone nor earth. When ground and taken with wine, it is effective for treating pixiji qi (stubborn accumulative gas/pathogens). Once exposed to fire, it becomes toxic and must not be taken hastily. The method for obtaining Piyin: Place raw Piyin on fire, cover it with a vessel, allowing the fumes of Piyin to rise and adhere to the inverted vessel, where they condense. They accumulate and hang down like milk droplets; those that are long and pointed are superior, while flat and short ones are inferior. *Tujing* refers to large chunks. Large chunks are already of lower grade, and flakes resembling fine dust are of the lowest grade. For medicinal use, the form resembling long, pointed milk droplets should be selected, requiring utmost caution and precision.
Processed by water levigation, it treats yi (nebulae/opacities) in the eyes. Leather craftsmen also use it to grind off dirt from leather; no other stone is better for this purpose. In the section on Shixie (Stone Crab), it mentions: Fushi (Pumice), neutral in nature, non-toxic, relieves thirst, treats lin syndrome (dysuria), and kills toxins from wild beasts. This entry should be merged here.
For treating Dafeng ji (leprosy/great wind disease). There is another method requiring calcination. Jin Xingshi (Gold-star Stone) is found within Cangshi (Grey Stone), having golden bran-like flakes on the exterior. Yin Xingshi (Silver-star Stone) has silver-colored bran-like flakes. Another variety is deep cyan, hard and moist, containing golden bran-like flakes inside. This variety is not used medicinally; artisans grind it to make vessels or women's hair ornaments. The rest follows the classic records.
