味甘，平。主五脏百病。柔筋强骨，安魂魄，长肌肉，益气，久服耐寒暑（《御览》引
耐字多作能，古通），不饥渴，不老神仙。人临死服五斤，死三年，色不变。一名玉札（《御
览》引作玉浓。《初学记》引云，玉桃，服之长生不死。《御览》又引云∶玉桃，服之长生不
死。若不得早服之，临死日服之，其尸毕天地不朽，则杜疑当作桃）。生山
《吴普》曰∶玉泉，一名玉屑，神农、岐伯、雷公∶甘；李氏∶平。畏冬华，恶青竹
（《御览》）。白玉杜如白头公（同上。《事类赋》引云∶白玉体如白首翁）。
案∶《周礼》∶玉府、王斋，则供食玉。郑云∶玉是阳精之纯者，食之以御水气。郑
司农云∶王斋，当食玉屑。《抱朴子·仙药篇》云∶玉，可以乌米酒及地榆酒化之为水，亦
可以葱浆消之为 ，亦可饵以为丸，亦可烧以为粉，服之，一年以上，入水不沾，入火
，刃之不伤，百毒不犯也。不可用已成之器，伤人无益，当得璞玉，乃可用也。得于阗国白
玉，尤善。其次，有南阳徐善亭部界界中玉，及日南卢容水中玉，亦佳。
味甘，温。主咳逆上气，明目益精，安五脏，通百节，利九窍，下乳汁（《御览》引云∶

《吴普》曰∶钟乳，一名虚中。神农∶辛；桐君、黄帝、医和∶甘；扁鹊∶甘，无毒（
《御览》引云∶李氏，大寒）。生山谷（《御览》引云∶太山山谷），阴处岸下，溜汁成（《御
览》引作溜汁所成聚），如乳汁，黄白色，空中相通，二月、三月采，阴干（凡《吴普本草》
，掌禹锡所引者，不复注，惟注其出《御览》诸书者）。
《名医》曰∶一名公乳，一名芦石，一名夏石。生少室及太山，采无时。
案∶《范子计然》云∶石钟乳，出武都，黄白者，善（凡引《计然》，多出《艺文类聚
》、《文选注》、《御览》及《大观本草》）。《列仙传》云∶ 疏，煮石髓而服之，谓之石钟乳，
钟，当为潼。说云∶乳汁也；钟，假音字。
味甘，性平。主治五脏各种疾病。能柔润筋骨、强健骨骼，安定魂魄，促进肌肉生长，补益元气，长期服用能抵御寒暑（《太平御览》引用时，“耐”字多写作“能”，古文中通用），使人不饥不渴，延缓衰老，如同神仙一般。人在临死前服用五斤，死后三年，面色不变。又名玉札（《太平御览》引作“玉浓”。《初学记》引用说：“玉桃，服用它可以长生不死。”《太平御览》又引用说：“玉桃，服用它可以长生不死。”如果来不及提前服用，在临终当日服用，尸体直至天地毁灭也不会腐朽，那么杜预的注释应当是“桃”字）。产于山中。
《吴普》记载：玉泉，又名玉屑。神农、岐伯、雷公认为其味甘；李氏认为其性平。畏忌冬华，厌恶青竹（《太平御览》）。白玉质地像白头老人（同上。《事类赋》引用说：“白玉体质像白发老翁”）。
按语：《周礼》记载：玉府、王斋，则供应食用玉石。郑玄注释说：玉是阳气精华中纯粹的部分，食用它可以抵御水湿之气。郑司农说：王斋，应当食用玉屑。《抱朴子·仙药篇》说：玉，可以用乌米饭酒和地榆酒将其化为水，也可以用葱汁将其溶解为浆，还可以研磨成丸服用，也可以烧制成粉服用。服用一年以上，入水不沾身，入火不烧伤，刀刃不能伤害，百毒不能侵犯。不可使用已经制成的玉器，那样伤人且无益，应当获取未经雕琢的璞玉，才可以使用。得到于阗国的白玉，尤其好。其次，有南阳徐善亭部界中的玉，以及日南卢容水中的玉，也很好。
味甘，性温。主治咳嗽气逆，明目益精，安定五脏，通畅关节，利九窍，下乳汁（《太平御览》引用说：一名留公乳。《大观本草》作一名公乳。黑字）。生于山谷。
《吴普》记载：钟乳，又名虚中。神农认为其味辛；桐君、黄帝、医和认为其味甘；扁鹊认为其味甘，无毒（《太平御览》引用说：李氏认为其大寒）。生于山谷（《太平御览》引用说：太山山谷），阴处岸下，滴落的汁液凝结而成（《太平御览》引作“溜汁所成聚”），状如乳汁，黄白色，内部中空相通，二月、三月采集，阴干（凡是《吴普本草》，掌禹锡所引用的部分，不再加注，只注明出自《太平御览》等书的条目）。
《名医别录》记载：一名公乳，一名芦石，一名夏石。产于少室山及泰山，随时可以采集。
按语：《范子计然》说：石钟乳，出产于武都，黄白色的为好（凡引用《计然》，多出《艺文类聚》、《文选注》、《太平御览》及《大观本草》）。《列仙传》说：赤松子煮石髓而服用它，称之为石钟乳，“钟”字，应当通“潼”。解释说：乳即乳汁；钟，是假借音字。
Taste is sweet, nature is neutral. It primarily treats various diseases of the five Zang organs. It softens tendons and strengthens bones, calms the Hun and Po spirits, promotes muscle growth, supplements Qi, and long-term consumption enables one to withstand cold and heat (The *Taiping Yulan* cites "endure" as often written as "can", interchangeable in ancient texts), preventing hunger and thirst, delaying aging, making one like an immortal. If taken five jin before death, the body remains unchanged in color for three years after death. Also known as Yu Zha (Jade Tally) (*Taiping Yulan* cites as "Yu Nong". *Chuxue Ji* cites: "Jade Peach, consuming it grants immortality." *Taiping Yulan* again cites: "Jade Peach, consuming it grants immortality." If not taken early, taking it on the day of death ensures the corpse remains intact until heaven and earth perish; thus Du Yu's annotation should likely be "Peach"). Grows in mountains.
Wu Pu states: Yu Quan, also known as Yu Xie (Jade Dust). Shennong, Qibo, and Leigong consider its taste sweet; Li Si considers its nature neutral. It fears Dong Hua and dislikes Qing Zhu (Green Bamboo) (*Taiping Yulan*). White Jade resembles a white-headed old man (ibid. *Shilei Fu* cites: "White Jade's texture is like a white-haired elder").
Commentary: The *Rites of Zhou* records: The Office of Jade and the King's fasting provisions supply edible jade. Zheng Xuan annotates: Jade is the pure essence of Yang Qi; consuming it repels dampness. Zheng Sinong states: For the King's fasting, powdered jade should be consumed. *Baopuzi · Chapter on Immortal Drugs* states: Jade can be dissolved into water using black rice wine or Sanguisorba officinalis wine, or dissolved into paste using green onion juice. It can also be ground into pills, or calcined into powder. After more than one year of consumption, one does not get wet in water, is unburned by fire, unharmed by blades, and immune to all poisons. Do not use already crafted jade vessels, as they are harmful and useless; one must obtain raw, uncarved jade (Pu Yu) for use. White jade from Khotan is especially good. Next best are jade from the Xu Shanting area in Nanyang, and jade from Lu Rong waters in Rinan, which are also excellent.
Taste is sweet, nature is warm. It primarily treats cough with rebellious Qi, brightens the eyes and benefits Jing (Essence), calms the five Zang organs, unblocks joints, benefits the nine orifices, and promotes lactation (*Taiping Yulan* cites: Also known as Liu Gong Ru. *Daguan Bencao* writes: Also known as Gong Ru. Black character). Grows in valleys.
Wu Pu states: Zhong Ru (Stalactite), also known as Xu Zhong. Shennong considers its taste pungent; Tong Jun, Huangdi, and Yi He consider its taste sweet; Bian Que considers its taste sweet and non-toxic (*Taiping Yulan* cites: Li Si considers it extremely cold). Grows in valleys (*Taiping Yulan* cites: Tai Mountain valleys), in shady places under riverbanks, formed from dripping fluids (*Taiping Yulan* cites as "formed from accumulated drips"), resembling milk, yellowish-white, internally hollow and connected. Harvested in February and March, dried in shade (For citations from *Wu Pu Bencao* by Zhang Yuxi, no further notes are added; only those cited from *Taiping Yulan* etc. are noted).
Famous Physicians' Record states: Also known as Gong Ru, Lu Shi, Xia Shi. Grows at Mount Shaoshi and Mount Tai, harvestable at any time.
Commentary: *Fanzi Jiran* states: Shi Zhong Ru (Stone Stalactite) originates from Wudu; yellowish-white ones are superior (Citations of *Jiran* mostly come from *Yiwen Leiju*, *Wenxuan Zhu*, *Taiping Yulan*, and *Daguan Bencao*). *Lie Xian Zhuan* states: Chi Songzi boiled stone marrow and consumed it, calling it Shi Zhong Ru. The character "Zhong" should be read as "Tong". Explanation: Ru means milk; Zhong is a phonetic loan character.
