膝头垢（出自《本草纲目》）：主治嘴唇紧缩的疮疡，用棉絮包裹后烧成灰研末外敷（出自《外台秘要》）。
癖石：主治消解癖积，治疗噎膈（出自《本草纲目》）。【产地/性质】（李时珍说）有人专心致志形成癖疾，以及病症块凝结成石头，像牛黄、狗宝、答之类，都是各种野兽的疾病。看那流星坠落变成石头，沙淋石、石淋（尿路结石），以及佛教徒的头骨囟门结成舍利子，都是精气凝结而成的。所以《格物论》说：“石头是气的核心。”群书所载如宝圭化石、老树化石，都是无情之物的变异；鱼、蛇、虾、蟹都能变成石头，是有情之物的变异。【质地】（程颐《遗书》说）波斯人发掘古墓，见到尸体肌肤都烂尽了，只有心脏坚硬如石头，锯开后里面有山水画的图案，旁边有一个女子倚栏凝视。大概是因为这个女子有喜爱山水的癖好，导致身体融化凝结成如此模样。（宋濂说）有一位僧人乘大船修持三昧法，示寂后火化，只有心脏没有烧毁，形状像佛像，非金非石。又有一人行禅观法，死后火化，心脏内包着观音像，样样具备。（医书说）一人患症癖而死，火化后有块状物如石头。这些都是症癖顽凝成石的缘故，一并记录在此。【性理】（《世说新语》）记载贞节妇女登山望夫，化为石头，这大概是意志专一不分心，是有情之物到了极点必然返回无情。（《宋史》）记载石工采石陷入石穴，三年后被挖出还活着，见风就化为石头，这大概是吞纳石气久了便与之同化。既然活着的形体尚且完整，变成石头则变得顽固，心中症癖化为石头也是同样的道理。
有毒。人汗进入饮食中，食用后会让人人生疔毒（出自《本草纲目》）。【产地/性质】（李时珍说）汗出于心，在体内则为血，在体外则为汗，所以说“夺汗者无血，夺血者无汗”。【味道】咸。【性质】温。
有毒。眼泪：母亲哭泣时泪水滴入婴儿眼中，会使婴儿眼睛受伤生翳（出自《本草纲目》）。【产地/性质】（李时珍说）泪是肝的液汁，五脏六腑的津液都向上渗透于眼睛。凡是悲哀、笑、咳嗽，都会使火激于中心，心系紧张而脏腑都动摇，于是宗脉感应而液道开启，津液上溢，所以流出涕泣。正如蒸笼上水滴的意思一样。【味道】咸。
Knee Dust (from *Bencao Gangmu*): Mainly treats ulcers with tight lips. Wrap in cotton, burn to ash, grind into powder, and apply externally (from *Waitai Miyao*).
Pishi Stone: Mainly treats dissolving accumulations and managing Yige (dysphagia/esophageal obstruction) (from *Bencao Gangmu*). [Origin/Nature] (Li Shizhen said) Some people develop obsessions through intense focus, and pathological masses condense into stones, similar to Niu Huang (Calculus Bovis), Gou Bao, or Da. These are diseases of various beasts. Observing that meteorites fall and become stones, Sha Lin Shi (sand-lithiasis stones), Shi Lin (urinary calculi), and the Sarira (relics) formed in the fontanelle of Buddhist practitioners, all result from the condensation of Jing Qi (Essence and Qi). Thus, *Gewu Lun* states: "Stones are the core of Qi." Records in various books mention treasures turning into stone and old trees petrifying; these are transformations of inanimate objects. Fish, snakes, shrimp, and crabs can also petrify; these are transformations of animate beings. [Texture] (Cheng Yi's *Yishu* says) Persians excavated an ancient tomb and found that while the flesh had completely decomposed, the heart remained hard as stone. When sawn open, it contained patterns resembling landscapes, with a woman leaning on a railing gazing intently. This was likely because this woman had an obsession with mountains and waters, causing her body to melt and condense thusly. (Song Lian said) A monk sailing a large boat practiced Samadhi. After his passing, upon cremation, only his heart did not burn, taking the shape of a Buddha statue, neither metal nor stone. Another person practiced Chan meditation; after death and cremation, his heart contained an image of Guanyin (Avalokitesvara Bodhisattva), complete in every detail. (Medical texts say) A person died of Zhen Pi (masses and accumulations); upon cremation, a stone-like mass remained. These are all instances of stubborn pathological masses condensing into stones, recorded here together. [Nature/Principle] (*Shishuo Xinyu*) records a chaste woman who climbed a mountain waiting for her husband until she turned into stone. This is likely due to undivided will, where extreme emotion in animate beings reverses into insensitivity. (*History of Song*) records a stonecutter who fell into a stone cave and was dug out alive three years later; upon exposure to wind, he turned into stone. This is likely due to long-term inhalation of Stone Qi, leading to transformation into one with it. Since living forms remain whole, petrification implies stubbornness; thus, mental obsessions transforming into stones follows the same logic.
Toxic. Human Sweat entering food or drink causes those who consume it to develop Ding Du (furuncles/carbuncles) (from *Bencao Gangmu*). [Origin/Nature] (Li Shizhen said) Sweat originates from the Heart; internally it becomes Blood, externally it becomes Sweat. Hence it is said: "Those deprived of sweat have no blood; those deprived of blood have no sweat." [Taste] Salty. [Nature] Warm.
Toxic. Tears: If a mother's tears fall into an infant's eyes while crying, it damages the infant's eyes and causes Opacity (nebulization of the cornea) (from *Bencao Gangmu*). [Origin/Nature] (Li Shizhen said) Tears are the fluid of the Liver. The Jin Ye (Body Fluids) of the five zang and six fu organs all seep upwards into the eyes. Whenever there is sorrow, laughter, or coughing, Fire stirs at the center, the Xin Mai (Heart Vessel) becomes tense, and the zang-fu organs tremble. Consequently, the Zong Mai (Gathering Vessels) are stimulated, the fluid pathways open, Jin Ye overflows upwards, resulting in the discharge of mucus and tears. This is analogous to water droplets forming on top of a steamer. [Taste] Salty.
