【石蟹】
质地沉重，性味咸寒。具有泻下、明目的功效。治疗青盲（视力模糊或失明）及目生翳障，治疗时行热病（传染性热性疾病），解除各种金石类药物的毒性。用醋研磨后外敷，可治疗痈肿。产于南海。其外形完全是螃蟹的样子，但质地却像石头一样。需细细研磨，用水飞法处理后使用。
【石灰】
质地沉重，能和血、促进创伤愈合。
咸味入血分，甘味能补血。治疗金创骨折损伤、痈疽肿毒（用醋研磨涂抹），止痛并促进肌肉生长（人在受杖刑时，服用三到五钱，疼痛和损伤就不严重）。产于四川和广东地区。是黑色的小石子，一包里有几百枚。
【砒石】
质地沉重，性燥，能祛除寒积。
性辛热，有大毒。治疗坚硬积聚和顽固性冷症，寒湿引起的风痹（苏恭说：治疗寒冷疾病效果最好。《名医别录》说：不经过炼制直接服用，会致死。这种石头生长在雪山覆盖不到的地方，放入水中也不会结冰。李时珍说：其性气与砒石相近。《博物志》记载：鹳鸟在孵卵时，取这种石头暖脚。这是错误的说法）。有疮石、白砒等几种，火烧后只能解散，不能使其失去坚硬特性。放在水中不结冰的是真品。畏忌羊血。
【信石（砒霜）】
大燥，能劫夺痰涎。
味辛苦且咸。性大热大毒，其中砒霜的毒性尤为猛烈。专门能够燥湿化痰，可作为催吐药使用。治疗胸膈间的风痰，截断疟疾发作，消除哮喘。外用可腐蚀败坏的肉芽，杀虫并使痔疮枯萎。产于信州，所以名叫信石，衡州的次之。它是锡矿的矿物苗裔（所以锡壶也被认为有毒）。未炼制的叫砒黄，炼制后的叫砒霜。畏惧绿豆、冷水和羊血。
【锻石】
质地沉重，能燥湿、止血、促进肌肉生长。
性辛温而药性猛烈。能使物体坚固、消散瘀血，定痛并促进肌肉生长，止住金创出血（腊月时用黄牛胆汁调和，纳入牛胆中，阴干后使用），杀灭疮虫（有人小腿肚长了一个疮，久了变成瘘管，百药无效，自己料定必死无疑。一个村民看见后说：这是鳝鱼漏。用锻石温水浸泡、熏洗，感觉痒就是见效了。洗了几次后，痊愈了）。腐蚀恶肉，不留疤痕（配合药物点痣）。解酒酸（酒家多用此物，但有灰的酒会伤人）。内服可止泻痢、崩漏带下，收敛阴挺（阴道肉突出，也叫阴菌，或者产后子宫脱垂/阴道口不闭合。熬黄后用水泡，澄清后温热清洗）、脱肛，消除积聚和结核。风化过的品质较好。
【圹灰】
火毒已经散发，主要治疗顽固性疮疡、脓水淋漓，收敛伤口效果尤其奇妙。
[Shixie (Stone Crab)]
Heavy in nature, with a pungent and cold property. It has the effects of purging and brightening the eyes. It treats Qingmang (visual impairment or blindness) and corneal opacity, epidemic febrile diseases (infectious febrile conditions), and detoxifies various mineral drugs. When ground with vinegar and applied externally, it treats carbuncles and swelling. It is produced in the South Sea. Its appearance is exactly that of a crab, but its texture is like stone. It should be finely ground and used after being processed by water flotation (water flying).
[Limestone]
Heavy in nature; it harmonizes blood and promotes healing of injuries.
The salty flavor enters the Blood aspect, and the sweet flavor tonifies blood. It treats metal wounds and fractures, carbuncles, sores, and toxic swellings (applied as a paste ground with vinegar), relieves pain, and generates flesh (when humans are subjected to beating with sticks, taking three to five qian can reduce severe pain and injury). It is produced in Sichuan and Guangdong. It consists of small black stones, with hundreds in one package.
[Pishí (Arsenic Stone)]
Heavy in nature; drying, dispels cold accumulation.
Pungent and hot, possessing great toxicity. It treats hard accumulations and chronic cold syndromes, wind-bi caused by cold-dampness (Su Gong stated: it is best for treating cold diseases. *Bielu* stated: taking it unrefined causes death. This stone grows in mountains without snow and does not freeze when put in water. Li Shizhen stated: its nature and qi are similar to Pishuang. *Bowuzhi* states: storks take this stone to warm their feet while incubating eggs. This is incorrect.). There are varieties such as Chuangshi and Bai Pi. Burning them only disperses them but cannot remove their hardness. Those that do not freeze in water are authentic. It is antagonistic to sheep blood.
[Xinshi (Arsenic Trioxide/Pishuang)]
Greatly drying, seizes phlegm.
Pungent, bitter, and salty. Greatly hot and highly toxic, especially Pishuang (Arsenic Trioxide). It specializes in drying phlegm and can be used as an emetic. It treats wind-phlegm in the chest and diaphragm, interrupts malaria, and eliminates asthma. Externally, it erodes necrotic tissue, kills parasites, and withers hemorrhoids. It is produced in Xinzhou, hence the name Xinshi; those from Hengzhou are secondary. It is the mineral offspring of tin (thus tin pots are also considered toxic). Unrefined is called Pi Huang, refined is called Pi Shuang. It is inhibited by mung beans, cold water, and sheep blood.
[Duan Shi (Calcined Iron Ore/Slag)]
Heavy in nature; dries dampness, stops bleeding, generates flesh.
Pungent and warm, with a fierce nature. It solidifies substances, dissipates blood stasis, relieves pain, generates flesh, and stops bleeding from metal wounds (mixed with bile of a yellow cow in the twelfth lunar month, placed back into the gallbladder, dried in shade, and then used). It kills parasite worms (A person had a sore on the calf that became a fistula over time; all medicines failed, and he believed he would die. A villager saw it and said: This is an eel fistula. Soak, fumigate, and wash with warm Duan Shi solution; feeling itching indicates efficacy. After several washes, it healed.). It erodes malignant flesh without leaving scars (used with herbs to remove moles). Relieves wine acidity (wine merchants use it often, but wine containing ash harms people). Internally, it stops diarrhea and dysentery, metrorrhagia and leukorrhea, retracts prolapse (vaginal protrusion, also called Yin Jun, or failure of the vaginal opening to close postpartum. Boil until yellow, soak in water, clarify, and wash with warm liquid); rectal prolapse; and resolves accumulations and tubercles. Weathered ones are superior.
[Kuang Hui (Graveyard Ash/Fire Ash)]
Fire toxicity has been expelled. It mainly treats stubborn ulcers with dripping pus and is excellent for closing wounds.
