甘，温。为阳明经药物。因受金银之气，故治疗眼疾是其主要功效。李时珍常用炉甘石（Luganshi, Calamina）经醋淬处理，与海螵蛸（Haipiaoxiao, Cuttlefish Bone）、硼砂（Pengsha, Borax）各一两，研成细末，用于点眼治疗各种眼病，效果极佳。加入朱砂（Zhusha, Cinnabar）五钱，则药性不粘腻。配合枯矾（Kufan, Alum）、胭脂（Yanzhi, Rouge）、麝香（Shexiang, Musk），吹入耳中可止耳漏出汁。配合真蚌粉（Zhenbangfen, Real Pearl Powder），扑洒于阴部可治汗湿瘙痒。配孩儿茶（Haiercha, Katechu），搽涂下疳阴疮。配青黛（Qingdai, Indigo Naturalis）、冰片（Bingpian, Borneol），搽涂下疳。
凡使用炉甘石，需用炭火煅烧至红透，用童便（Tongbian, Child's Urine）淬炼，或用黄连煎水淬炼七次，洗净后研成粉末，用水飞法（Shuifei, Water Levigation）处理后晒干备用。
甘，大寒。治疗热结、热嗽、热疳、热眼等症状。配合海金沙（Haijinsha, Lygodii Spora）、滑石（Huashi, Talcum），治疗膀胱热秘。配合大黄（Dahuang, Rhubarb）、栀子（Zhizi, Gardenia Fruit），治疗眼睑红肿赤痛。需细研后用水飞法处理，否则会导致淋证。
能伏制硫黄。
甘、咸、平。活血凉血。治疗金创骨折损伤。用陈酒送服，治疗跌打损伤引起的肿痛。用醋磨碎，敷贴疮痈。调葱汁，涂抹赤瘤丹毒。调牛胶，治疗香港脚（Honggangjiao, Beriberi/Chilblains）肿痛。配合甜瓜子（Tianguazi, Melon Seed）一两，乳香（Ruxiang, Frankincense）、没药（Moyao, Myrrh）各一钱，研成细末，每次服用五钱，用热酒调服，小儿服用三钱，治疗损伤接骨；外用将黄米粥涂在纸上，撒上牡蛎末（Muli, Oyster Shell），包裹固定，再用竹篦夹住。研成细末，卷纸做成捻子，点灯后吹灭，用黑烟熏治卷毛倒睫。
又名鹅管石（Eguanshi, Stalactite）。
蛇床（Shechuangzi, Cnidium Fruit）为其使药。畏紫石英（Zishiyang, Fluorite）、蓑草（Suocao, likely referring to a specific herb, contextually kept as is or generalized if unknown, here kept as 蓑草）。恶牡丹（Mudanpi, Tree Peony Root Bark）、玄石（Xuan Shi, Black Stone/Magnetite? Contextual mineral）、牡蒙（Mumen, likely a specific herb/mineral）、人参（Renshen, Ginseng）、术（Zhu, Atractylodes）。忌食羊血。能被韭实、独蒜、胡葱、胡荽、麦门冬、猫儿眼草所伏制。
甘，温。入足少阴肾经气分。通利九窍，疏通百节，壮补元阳，治疗脚冷。
配合漏芦（Loulu, Rhapontic Radix）、通草（Tongcao, Tetrapanacis Medulla），促进乳汁下行。
质地光润轻松，形状像鹅翎管。用沉香、藿香、甘松、白茅根水煮过，再用天葵、甘草同煮，焙干后研细，水飞澄清，过绢筛晒干，再研细收存使用。服用钟乳石者终身忌服术、人参，犯此禁忌者多致死。药石性质猛烈，不可因为能补阳助孕就长期不间断服用，以免招致突然的灾祸。况且阳虚内寒的人极少，滥用会激发火热生风，导致万病蜂起。即使适宜服用而长期服用，也难免遭受淋证、口渴、痈疽等祸害。
Sweet, warm. It is a drug of the Yangming channel. Because it absorbs the qi of gold and silver, it is an essential medicine for treating eye diseases. Li Shizhen often used Luganshi (Calamina) quenched with vinegar, combined with Haipiaoxiao (Cuttlefish Bone) and Pengsha (Borax), each one liang, ground into fine powder, to apply to the eyes for various eye diseases, which is very effective. Adding Zhusha (Cinnabar) five qian makes the property non-sticky. Combined with Kufan (Alum), Yanzhi (Rouge), and Shexiang (Musk), blown into the ear to stop discharge. Combined with Zhenbangfen (Real Pearl Powder), dusted on the genitals to treat sweat-induced itching. Paired with Haiercha (Katechu), applied to treat chancre sores in the genital area. Paired with Qingdai (Indigo Naturalis) and Bingpian (Borneol), applied to treat chancre.
Whenever using Luganshi (Calamina), calcine it over charcoal fire until red-hot, quench it in Tongbian (Child's Urine), or quench it seven times in decoction of Huanglian (Coptis Rhizome). Wash clean, grind into powder, process by water levigation (Shuifei), dry, and use.
Sweet, very cold. Treats heat accumulation, hot cough, hot malnutrition (gan), hot eyes, etc. Paired with Haijinsha (Lygodii Spora) and Huashi (Talcum), treats bladder heat constipation. Paired with Dahuang (Rhubarb) and Zhizi (Gardenia Fruit), treats swollen and red eyelids. Must be finely ground and processed by water levigation; otherwise, it causes strangury.
It can subdue Liu Huang (Sulfur).
Sweet, salty, neutral. Invigorates blood and cools blood. Treats traumatic injuries and fractures. Taken with aged wine, it treats swelling and pain from bruises. Ground with vinegar, applied to sores and abscesses. Mixed with scallion juice, applied to erysipelas and toxic rashes. Mixed with ox glue, treats Honggangjiao (Beriberi/Chilblains) swelling and pain. Paired with Tianguazi (Melon Seed) one liang, Ruxiang (Frankincense) and Moyao (Myrrh) one qian each, ground into powder. Take five qian per dose, mixed with hot wine; children take three qian. Treats trauma and bone fractures. Externally, spread yellow millet porridge on paper, sprinkle Muli (Oyster Shell) powder, wrap firmly, and clamp with a bamboo splint. Grind into fine powder, roll paper into a wick, light it, blow out, and use the black smoke to fumigate inverted eyelashes.
Also known as Eguanshi (Stalactite).
Shechuangzi (Cnidium Fruit) is its guiding herb. It is incompatible with Zishiyang (Fluorite), Suocao, Mudanpi (Tree Peony Root Bark), Xuan Shi, Mumen, Renshen (Ginseng), and Zhu (Atractylodes). Avoid sheep blood. It is subdued by Jiu Shi, Du Suan, Hu Cong, Hu Sui, Maidong (Ophiopogon Tuber), and Mao'er Yan Cao.
Sweet, warm. Enters the Qi aspect of the Foot Shaoyin Kidney channel. Opens the nine orifices, unblocks the hundred joints, strengthens primordial yang, and treats cold feet.
Paired with Loulu (Rhapontic Radix) and Tongcao (Tetrapanacis Medulla), promotes lactation.
The texture is smooth and light, shaped like a goose feather tube. Boil Chenxiang (Agarwood), Huoxiang (Patchouli), Gansong (Nardostachys Root), and Baimaogen (Imperata Rhizome) in water, then boil again with Tiankui and Gancao (Licorice Root). Dry, grind fine, process by water levigation, clarify, pass through silk gauze, dry, grind fine again, and store. Those who consume Zhongru Shi (Stalactite) must avoid Zhu and Renshen for life; those who violate this often die. Mineral drugs are fierce in nature. Do not take them continuously just because they tonify yang and aid conception, lest you bring about sudden disaster. Moreover, cases of internal cold due to yang deficiency are rare (one or two in a hundred); reckless use will ignite fire and generate wind, causing myriad diseases to arise. Even if suitable for consumption, long-term use inevitably leads to strangury, thirst, and carbuncles/fistulas.
