气味甘温，无毒。主治咳逆上气，明目，益精，安五脏，通百节，利九窍，下乳汁
（石钟乳一名虚中，一名芦石，一名鹅管石，皆取中空之意。石之津气钟聚成乳滴溜成
石，故名石钟乳。今倒名钟乳石矣。出太山少室山谷，今东境名山石洞皆有，唯轻薄中通形
如鹅翎管，碎之如爪甲，光明者为上。）
石钟乳乃石之津液融结而成，气味甘温。主滋中焦之汁，上输于肺，故治咳逆上气。中
焦取
汁奉心，化赤而为血，故明目。流溢于中而为精，故益精。精气盛，则五脏和，故安五脏。
血气盛，则百节和，故通百节。津液濡于空窍，则九窍自利。滋于经脉，则乳汁自下。
气味甘寒，无毒。主治咳逆，寒热烦满，下赤白，血闭，症瘕大热，炼饵服之，不
饥，轻身延年。
（禹余粮始出东海池泽及山岛中，今多出东阳泽州、潞州，石中有细粉如面，故曰余粮。
李时珍曰∶禹余粮乃石中黄粉，生于池泽，其生于山谷者，为太一余粮也。）
仲祖《伤寒论》云∶汗家重发汗，必恍惚心乱，小便已阴痛，宜禹余粮丸。全方失传，
世亦罕用。
气味甘平，无毒。主治咳逆上气，症瘕，血闭，漏下，除邪气，肢节不利。久服
耐寒暑，不饥，轻身，飞行千里，神仙。
陈藏器曰∶太，大也。一，道也。大道之师，即理化神君，禹之师也，师尝服之，故有
太一
之名。陶弘景曰∶《本草》有太一余粮、禹余粮两种，治体相同，而今世唯有禹余粮，不复
识太一矣。李时珍曰∶生池泽者，为禹余粮，生山谷者，为太一余粮，本是一物。晋宋以来
，不分山谷池泽，通呼为太一禹余粮，义可知矣。
[Shi Zhong Ru (Stalactite)]
The flavor is sweet and the nature is warm; it is non-toxic. It primarily treats cough with rebellious Qi, improves vision, benefits essence, calms the five Zang organs, unblocks all joints, facilitates the nine orifices, and promotes lactation.
(Shi Zhong Ru is also known as Xu Zhong, Lu Shi, and E Guan Shi, all names referring to its hollow interior. The fluid and Qi of stones gather and condense into milk-like droplets that fall and form stone, hence the name Shi Zhong Ru. Now it is inversely called Zhong Ru Shi. It originates from the valleys of Mount Tai and Mount Shaoshi. Currently, it is found in stone caves of famous mountains in the eastern regions. Those that are thin, light, hollow in the center, shaped like goose quill tubes, breakable like fingernails, and bright in luster are considered superior.)
Shi Zhong Ru is formed by the fusion and condensation of stone fluids; its flavor is sweet and nature warm. It primarily nourishes the juices of the Middle Jiao and transports them upward to the Lung, thus treating cough with rebellious Qi. The Middle Jiao extracts juices to support the Heart, transforming them red to become blood, thus improving vision. Flowing inward to become essence, it benefits essence. When essence and Qi are abundant, the five Zang organs harmonize, thus calming the five Zang organs. When blood and Qi are abundant, all joints harmonize, thus unblocking the joints. Fluids moisten the empty orifices, so the nine orifices facilitate naturally. Nourishing the meridians, lactation flows down naturally.
[Yu Yu Liang (Halloysitum)]
The flavor is sweet and the nature is cold; it is non-toxic. It primarily treats cough with rebellious Qi, alternating chills and fever, irritability and fullness, dysentery with red and white discharge, amenorrhea, excessive heat from zheng jia (masses), and when refined and taken, prevents hunger, lightens the body, and prolongs life.
(Yu Yu Liang originally originated from pools, marshes, and islands in the East Sea. Currently, it is mostly produced in Dongyang, Zezhou, and Luzhou. The stone contains fine powder resembling flour, hence the name Yu Liang. Li Shizhen stated: Yu Yu Liang is yellow powder within stones, growing in pools and marshes; those growing in mountain valleys are called Tai Yi Yu Liang.)
Zhang Zhongjing's *Shanghan Lun* states: For individuals who sweat frequently, inducing sweating again will inevitably lead to mental confusion and restlessness, and pain in the yin region after urination; Yu Yu Liang Wan is appropriate. The complete formula has been lost, and it is rarely used in the world today.
[Tai Yi Yu Liang (Halloysitum)]
The flavor is sweet and the nature is neutral; it is non-toxic. It primarily treats cough with rebellious Qi, zheng jia (masses), amenorrhea, metrorrhagia (leukorrhea/blood leakage), expels pathogenic factors, and alleviates stiffness in limbs and joints. Long-term consumption enables resistance to cold and heat, prevents hunger, lightens the body, and even allows flying for a thousand miles, becoming an immortal.
Chen Cangqi stated: Tai means great; Yi means Dao (the Way). The teacher of the Great Dao is the Divine Lord of Transformation and Rationalization, who was the teacher of Yu the Great. Since the teacher once consumed it, it bears the name Tai Yi. Tao Hongjing stated: The *Bencao* lists two types: Tai Yi Yu Liang and Yu Yu Liang. Their therapeutic properties are identical, but currently only Yu Yu Liang exists in the world, and Tai Yi Yu Liang is no longer recognized. Li Shizhen stated: Those growing in pools and marshes are called Yu Yu Liang, while those growing in mountain valleys are called Tai Yi Yu Liang; originally, they are the same substance. Since the Jin and Song dynasties, without distinguishing between mountain valleys and pools/marshes, they were collectively referred to as Tai Yi Yu Liang, the meaning of which can be inferred.
