（本经上品）
审形状辨土地。此不独具山全体，更藉外缘以相资也。具山全体，故功力勇悍乃尔。
【气味】甘温，无毒。
【主治】主咳逆上气，明目益精，安五脏，通百节，利九窍，下乳汁。
【核】曰∶生少室山谷及太山。第一出始兴者佳，江陵及东境名山石洞中亦有。按范成
大桂海志所说甚详。云桂林接宜、融山洞石穴中，钟乳甚多。仰视石脉涌起处，即有乳床，
白如玉雪，乃石液融结所成者。乳床下垂，如倒生山峰，峰端渐锐且长，若冰柱，柱端轻薄，
中空如鹅翎。乳水滴沥不已，且滴且凝，此乳之最精者，以竹管仰承取之。而炼治家又以鹅
管之端，尤轻明如云母爪甲者为胜。孙思邈曰∶乳石必须土地清白，光润如罗纹、鸟翮、蝉
翼，一切皆成白色者可用；其非土地者慎勿服之，杀人甚于鸩毒。别本注云∶凡乳生深洞幽
穴者，皆龙蛇潜伏之处，或袭龙蛇毒瓦斯，或洞口阴阳不均，或通风气，或黄色赤色，乳
无润泽，或煎炼火色不调，一煎以后，不复易水，服之令人发淋。又乳有三种∶一种石乳，
其洞纯石，石津相滋，阴阳交备，具蝉翼纹者，其性多温；一种竹乳，其洞遍生小竹，竹津
相杂，石状如竹，其性多平；一种茅乳，出茅山，其山土石相杂，遍生茅草，茅津相滋，形
质润滑，其性多寒，皆以光泽者为善。余处亦有，不可轻信。雷公曰∶凡使勿用头粗浓，并
尾大者，为孔公石，不用。色黑及经大火惊过，并久在地上收者，与曾经药物制者。须要鲜
明轻薄，而有光润，如鹅翎筒子者乃佳。修治，钟乳八两，用沉香、零陵香、藿香、甘松、
白茅各一两，水煮过，再煮汁，方用煮乳，一伏时，漉出。以甘草、紫背天葵各一两，同煮，
漉出拭干，缓火焙之，入臼杵粉，筛过，入钵中。令有力少壮者二三人，不住手研三日夜。
然后以水飞澄，罩以绢笼，日中晒干，入钵再研三万遍，乃以瓷盒收之。太清经炼钟乳法∶
取好末置金银器中，瓦一片，密盖，勿令泄气，蒸之，自然化作水也。之才曰∶蛇床为之使。
恶牡丹、玄石、牡蒙。畏紫石英、 草。忌羊肉。时珍曰∶亦忌参、术，犯之多死。土宿
真君曰∶钟乳产于阳洞之内，阳气所结，服之可柔五金。麦门冬、蒜、韭实、胡葱、胡荽、
猫儿眼，皆可服之。
（经云∶水势劣火，结为高山，钟乳本具水火二大矣。则乳质全类似水，而勇悍独专，
宁非火胜水劣乎。修治，水煮，仍交水火以济之。但煮则水胜于火，所以少平勇悍也。今世
多用火 ，反助长其勇悍，故每多石毒燃烧之患。）
先人云∶五脏安和，窍节通利，即地形仙矣。此属借资，大须保任，久与相习，乃成自

【 】曰∶乳乃石之灵液，具山之全体者也。顾山体有清浊，而乳之优劣因之。如妇人

【本经上品】
审察形状，辨别产地。这不仅仅具备山的整体特质，更借助外部条件相互资助。因为具备了山的整体特质，所以药力勇猛强悍到了这种程度。
【气味】味甘，性温，无毒。
【主治】主治咳嗽气逆，明亮双目，增益精气，安定五脏，疏通全身关节，通利九窍，下催乳汁。
【核证】曰：产于少室山谷及泰山。第一等产自始兴的药材最佳，江陵及东部边境的名山石洞中也有出产。查阅范成大《桂海志》所述非常详细。说桂林连接宜州、融州的山洞石穴中，钟乳非常多。仰视石脉涌起之处，就有乳床，洁白如玉雪，这是石液融化凝结而成的。乳床向下垂挂，像倒生的山峰，峰端逐渐变尖且长，如同冰柱，柱端轻薄，中空像鹅毛管。乳水滴落不停，边滴边凝结，这是最精华的钟乳，用竹管仰接收取。而炼制药材的人又以鹅管状的末端，尤其轻明如云母爪甲的为上乘。孙思邈说：钟乳必须产地土地清白，光泽润泽如罗纹、鸟羽、蝉翼，全部呈现白色的才可用；如果不是出自好土地的钟乳千万不要服用，其毒性杀人甚于鸩毒。其他版本注解说：凡是生长在深洞幽穴中的钟乳，都是龙蛇潜伏的地方，有的沾染了龙蛇的毒瓦斯，有的洞口阴阳不均，有的受通风气影响，或者颜色黄赤，钟乳没有润泽感，或者煎炼时火候不调，一次煎煮后不再换水，服用后会让人患上淋病。另外钟乳有三种：一种是石乳，洞穴纯石，石津互相滋润，阴阳兼备，具有蝉翼纹理的，药性多温；一种是竹乳，洞穴遍生小竹子，竹津混杂，石状像竹子，药性多平；一种是茅乳，产于茅山，那山土石混杂，遍生茅草，茅津互相滋润，形体质地润滑，药性多寒，都以有光泽的为优良。其他地方也有，不可轻信。雷公说：凡使用钟乳，不要用头粗厚、尾大的，那是孔公石，不用。颜色黑以及经过大火惊吓过的，以及在地下存放已久的，和曾经被药物炮制过的（均不用）。必须要鲜明轻薄，且有光润，像鹅毛管筒一样的才好。修治方法：钟乳八两，用沉香、零陵香、藿香、甘松、白茅各一两，用水煮过，再煮取汁，然后用这个汁来煮钟乳，一个时辰（约两小时），捞出。再用甘草、紫背天葵各一两，同煮，捞出擦干，用慢火焙干，放入臼中捣成粉，筛过，放入钵中。让有力气的年轻壮汉二三人，不停地研磨三天三夜。然后用水飞法澄清，罩上绢笼，在太阳下晒干，放入钵中再研磨三万遍，最后用瓷盒收藏。太清经炼制钟乳的方法：取好的粉末置于金银器中，盖上一片瓦，严密覆盖，不让气体泄漏，蒸它，自然会化成水。徐之才说：蛇床子作为使药。畏牡丹、玄石、牡蒙。忌紫石英、[缺字]草。忌羊肉。李时珍说：也忌人参、白术，犯之多数死亡。土宿真君说：钟乳产于阳洞之内，是阳气凝结而成，服用它可以柔化五金。麦门冬、蒜、韭菜籽、胡葱、胡荽、猫儿眼，都可以与钟乳同服。
（经文说：水势弱于火，凝结成为高山，钟乳本来兼具水火两大属性。那么乳质完全类似水，而勇悍特性独专，难道不是火胜水劣吗？修治时用水煮，仍是水火相交以济助它。但煮的时候水胜于火，所以稍微平和了勇悍之性。当今世人多用火煅，反而助长其勇悍，所以多有石毒燃烧的危害。）
先父说：五脏安和，窍节通利，就是地上的仙境了。这属于借助外物资助，非常需要保养任持，长久与之相习，才能成为自然。
【辨伪】曰：钟乳是石的灵液，具备山的整体特质。但是山体有清浊之分，钟乳的优劣因此不同。就像妇人资质各异，那么钟乳的浓薄，味道的甘淡，气味的腥香冷暖，它对滋养婴儿是否有好处，也自有分辨。所以钟乳必须先论产地，再审查形状，这样才能得到好药。只有天地之气，汇聚于名山而凝结成乳。看它的主治功效，一一可以推想，比如肺系填塞胀满，就不能分布诸气，所以咳嗽气逆，钟乳中空虚软，宛若肺系，何患填塞胀满，这是石液所钟，光润莹彻，所以明目，目也是水液所钟，洞见明暗，这是石中精髓，点滴不穷，所以增益精髓之体。这是艮山之液，能益真阴。然而五脏属至阴，必须宁静濡润，才能安和，若通百节，利九窍，下
[Shangpin Category of the Classic of Materia Medica]
Examine the shape and distinguish the origin. This is not only because it possesses the entirety of the mountain's characteristics, but also relies on external conditions for mutual support. Because it possesses the entirety of the mountain's characteristics, its medicinal power is so brave and fierce.
[Flavor and Property] Sweet, warm, non-toxic.
[Indications] Mainly treats cough with rebellious Qi (Ke Ni Shang Qi), brightens the eyes, benefits essence (Jing), calms the five Zang organs (Wu Zang), unblocks all joints (Bai Jie), facilitates the nine orifices (Jiu Qiao), and promotes lactation.
[Verification] Says: It grows in the valleys of Mount Shaoshi and Mount Tai. The best quality comes from Shixing; it is also found in the stone caves of famous mountains in Jiangling and the eastern regions. According to Fan Chengda's "Guanghai Zhi", the description is very detailed. It states that in the mountain caves and stone holes connecting Guilin, Yizhou, and Rongzhou, there are many Zhongru (Stalactite). Looking up at where the stone veins surge, there are "milk beds" (Ruchuang), white as jade and snow, formed by the melting and condensation of stone fluid. The milk bed hangs down like an inverted mountain peak, with the tip gradually becoming sharp and long, resembling an icicle. The tip of the icicle is thin and light, hollow like a goose feather quill. Milk drops continuously, condensing as they drip; this is the most refined Zhongru, collected by holding bamboo tubes upward to catch them. Those who refine medicines consider the end of the "goose tube" type, which is especially light and clear like mica fingernails, to be superior. Sun Simiao said: Zhongru must come from land that is clean and pure, lustrous and moist like brocade patterns, bird feathers, or cicada wings, and entirely white ones can be used; those not from such land should never be taken, as they kill more swiftly than poison. Another edition notes: Any Zhongru growing in deep caves and secluded holes is a place where dragons and snakes lurk; some may absorb dragon/snake toxic vapors, some have uneven Yin and Yang at the cave mouth, some are affected by wind currents, or appear yellow/red without luster, or were improperly calcined with inconsistent fire, or not changed water after one boiling; taking these causes Lin syndrome (strangury). Furthermore, there are three types of Zhongru: One is Stone Ru (Shi Ru), where the cave is pure stone, stone juices nourish each other, Yin and Yang are complete, and those with cicada-wing patterns tend to be warm in nature; One is Bamboo Ru (Zhu Ru), where small bamboos grow throughout the cave, bamboo juices mix with stone, the stone resembles bamboo, and tends to be neutral in nature; One is Thatch Ru (Mao Ru), produced in Maoshan, where the mountain has mixed soil and stone with abundant thatch grass, thatch juices nourish each other, the form and texture are smooth and lubricating, and tends to be cold in nature. All are best when lustrous. Others exist elsewhere, do not trust them lightly. Lei Gong said: When using Zhongru, do not use those with thick heads or large tails, as these are Konggong Shi (Hole Public Stone), which are useless. Do not use those that are black, exposed to intense fire, stored underground for a long time, or previously processed with drugs. They must be fresh, bright, thin, light, and lustrous, resembling goose feather quills, which are excellent. Processing method: Take 8 liang of Zhongru, boil with 1 liang each of Chenxiang (Aquilaria Wood), Linglingxiang (Lingnan Agastache), Huoxiang (Patchouli), Gansong (Nardostachys), and Baimao (Imperata Rhizome) in water. Boil again to extract juice, then use this juice to boil the Zhongru for one shichen (2 hours), remove and drain. Then boil with 1 liang each of Gancao (Licorice Root) and Zi Bei Tian Kui (Oxalis corymbosa) together, remove, wipe dry, and slow-roast. Pound into powder in a mortar, sieve, and put into a bowl. Have two or three strong young men grind continuously for three days and nights. Then clarify by water levigation, cover with silk gauze, dry in the sun, pound again in a bowl for 30,000 times, and store in a porcelain box. Taqing Jing method for refining Zhongru: Take fine powder, place in gold or silver vessel, cover tightly with a tile to prevent gas leakage, steam it until it naturally turns into water. Xu Zhicai said: Shechuangzi (Cnidium Fruit) acts as an assistant drug. It is incompatible with Mudan (Tree Peony Root Bark), Xuan Shi (Black Stone), and Mumeng (Dioscorea Polystachya). It fears Zhiyanshi (Purple Quartz) and [missing character] Cao. Avoid mutton. Li Shizhen said: It also conflicts with Renshen (Ginseng) and Baizhu (Atractylodes Macrocephala); violating this often leads to death. Tusuxen Jun said: Zhongru is produced inside Yang caves, condensed from Yang Qi; taking it can soften the five metals. Maimendong (Ophiopogon Tuber), garlic, leek seeds, Hucong (Allium hookeri), Huyi (Coriander), and Mao'er Yan (Aconitum carmichaelii side root) can all be taken with it.
(The Classic says: Water power is inferior to Fire, condensing to form high mountains. Zhongru inherently possesses both Water and Fire elements. Since the substance of the ru resembles water, yet its brave/fierce nature is exclusive, does this not indicate Fire overcoming Water? In processing, boiling with water still involves the interaction of Water and Fire to balance it. However, boiling makes Water superior to Fire, thus slightly moderating its fierce nature. Nowadays, people mostly use calcination/fire, which instead enhances its fierceness, leading to frequent hazards of stone toxicity and burning sensations.)
My late father said: When the five Zang organs are harmonious and orifices/joints are unblocked, one achieves a terrestrial paradise. This belongs to borrowing external aid; one must carefully preserve and nurture it. Only through long-term habituation can it become natural.
[Analysis] Says: Ru is the spiritual fluid of stone, possessing the entirety of the mountain's characteristics. However, since mountain bodies vary in purity and turbidity, the quality of Ru varies accordingly. Just as women differ in constitution, so too do the thickness of Zhongru, the sweetness or blandness of taste, and the fishy/fragrant, cold/warm nature of its Qi; whether it nourishes infants effectively also has its distinctions. Therefore, Zhongru must first be evaluated by origin, then by shape, to ensure acquisition of the good. Only the Qi of Heaven and Earth, concentrated in famous mountains, condenses into Ru. Observing its indications, one can deduce them one by one: For instance, if the lung system is blocked and distended, it cannot distribute Qi, causing cough and rebellious Qi. Zhongru is hollow and void, resembling the lung system; how could it suffer from blockage and distension? It is concentrated stone fluid, lustrous and transparent, thus brightening the eyes. The eyes are also concentrated water fluid, seeing clearly in light and dark. This is the marrow/essence of the stone, inexhaustible drop by drop, thus benefiting the body of essence. This is the fluid of Gen Mountain (Mountain Trigram), able to benefit True Yin. However, the five Zang organs belong to Extreme Yin, requiring tranquility and moisture to be harmonious. If it unblocks all joints, facilitates the nine orifices, and lowers...
