锡吝脂主治眼睛生翳膜，用火烧红的铜针轻轻点涂患处，然后敷上药，不会感到疼痛。又主治各种风邪之气以及三焦消渴症（以多饮、多食、多尿为主要表现的病证），可将其纳入丸剂中服用。
（《本草纲目》）【名称】银矿悉蔺脂。【产地】（李时珍说）这是波斯国的银铆钉，也写作“悉蔺脂”。【配伍治疗】（《普济方》）治疗小儿天吊病（一种以头项强直、角弓反张为特征的惊风病）、痰涎过多、抽搐不定：取锡吝脂一两，用水淘洗至黑汁流尽；水银一分，用小枣肉研磨至不见银色星点；牛黄半分，麝香半分，共同研匀，用粳米饭制成如黍米大小的丸药。每次服用三十二丸，用新汲水下送服，名为“保命丹”。
铁斧主治妇女难产、胎位不正、胞衣不下，将铁斧烧红后浸入酒中，饮酒服用。也可用于治疗产后血瘕（腹内结块）、腰腹痛。（收录于《本草纲目》总录诸铁器类中）
【用法】（李时珍说）古人有转女为男的方法：怀孕三个月时称为“始胎”，此时血脉尚未流动，胎儿形态随所接触之物而变化。这时适宜服药或采取特定措施，将斧头放在床底，刃口向下，不要让孕妇知道。如果担心她不信任，可以用鸡来试验，结果一窝小鸡都会变成雄鸡。这大概是胎化形成的自然道理。所以，吃公鸡肉是摄取自然界动物中纯阳的精气；佩戴雄黄是摄取大地出产物中纯阳的精气；持弓箭、使用斧斤等金属工具，是摄取人事活动中刚硬物品的阳气。由于气类相互感应，造化在暗中转移，这是物理规律的必然结果。因此，孕妇看到神像或异物，容易生出鬼怪之念，这就是征兆。象牙的纹理随着象的形状生长，山药的形状随着人的形象变化，告诉灶神鸡蛋就能孵出小鸡，用笤帚扫猫就能导致怀孕。万物尚且有感应，何况是人呢？
【治疗】（陈藏器说）凡是人身上的赘生物（如疣、痣等），可以听任别人在钉棺材下斧头声音的时候，立刻动手连续擦拭十四遍，之后自然会消退平整。产妇不宜使用。
大刀环主治难产数日胎儿不出，将大刀环烧红后浸入一杯酒中，一次性服下。（收录于《本草纲目》总录诸铁器类中）

Xilin Zhi (Silver Mine Resin) primarily treats pterygium (a growth of fleshy tissue on the eye). It is applied by lightly dabbing the affected area with a copper needle heated in fire, followed by applying the medicine; this causes no pain. It also treats various wind-pathogenic factors and Sanjiao Xiao Ke (Sanjiao Wasting-Thirst Syndrome, characterized by excessive thirst, hunger, and urination), and can be incorporated into pill formulations for oral administration.
(Compendium of Materia Medica) [Name] Yin Kuang Xi Lin Zhi (Silver Ore Xi Lin Zhi). [Origin] (Li Shizhen states) This is the silver rivet from Persia, also written as "Xi Lin Zhi". [Preparation and Treatment] (Pu Ji Fang) For treating infant Tian Diao disease (a type of convulsive disorder characterized by opisthotonos and head retraction), excessive phlegm-saliva, and irregular spasms: Take 1 liang of Xilin Zhi, wash it with water until the black liquid runs clear; 1 fen of Mercury (Hydrargyrum), grind it with the flesh of a small jujube until no metallic stars are visible; 0.5 fen of Niuhuang (Calculus Bovis, Bezoar); 0.5 fen of Shexiang (Moschus, Musk). Grind them uniformly together, mix with rice porridge to form pills the size of millet seeds. Administer 32 pills per dose, washed down with fresh well-water. This formula is named Baoming Dan (Life-Preserving Pill).
Tie Fu (Iron Axe) primarily treats difficult labor in women, malpresentation, and retained placenta. Heat the iron axe red-hot, quench it in wine, and drink the wine. It is also used to treat postpartum blood masses (abdominal masses due to blood stasis) and lower back/abdominal pain. (Recorded in the General Record of Iron Utensils within Compendium of Materia Medica)
[Usage] (Li Shizhen states) The ancients had a method to change the sex of the fetus: At three months of pregnancy, known as "Shi Tai" (Initial Fetus), the blood vessels have not yet fully circulated, and the fetus's form changes according to what it encounters. At this time, one should take specific medicines or measures, placing an axe under the bed with the blade facing downward, without letting the pregnant woman know. If she doubts it, one can test it with chickens; the result is that all chicks in a clutch will become male. This is likely the natural principle of fetal transformation. Therefore, eating rooster meat extracts the pure yang essence from animals in nature; wearing Realgar (Realgar, Orpiment) extracts the pure yang essence from minerals produced by the earth; holding bows/arrows or using axes/hatchets extracts the yang qi from rigid objects in human affairs. Due to the mutual感应 (sympathetic resonance) of similar qi, creation shifts secretly, which is an inevitable physical law. Thus, if a pregnant woman sees divine statues or strange objects, she may develop delusions of ghosts, which is a sign. Ivory patterns grow following the shape of the elephant; Chinese yam (Dioscoreae Rhizoma) changes shape following human forms; telling the stove god about chicken eggs leads to hatching chicks; sweeping a cat with a broom leads to pregnancy. Even things have such influences, let alone humans.
[Treatment] (Chen Cangqi states) For any skin excrescences (such as warts or moles) on the body, one can listen for the sound of an axe striking nails when coffin boards are being nailed. At that moment, immediately rub the lesion continuously for fourteen times (two sets of seven). Afterwards, it will naturally flatten and disappear. This should not be used by postpartum women.
Da Dao Huan (Large Sword Ring) primarily treats prolonged difficult labor where the fetus has not been delivered after several days. Heat the large sword ring red-hot, quench it in one cup of wine, and consume it in one dose. (Recorded in the General Record of Iron Utensils within Compendium of Materia Medica)
Jian Dao Gu (Scissor Shank) primarily treats infantile convulsions (Xiao Er Jing Feng). Qian Yi (Qian Shi) had a Jian Dao Gu Wan (Scissor Shank Pill). The usage involves grinding the ring part of the scissor shank, decocting it in water, and using the liquid to administer other medicines. (Recorded in the General Record of Iron Utensils within Compendium of Materia Medica)
Tie Zu (Iron Arrowhead) primarily treats hiccups caused by Stomach Heat. Use 72 iron arrowheads, decoct them in water, and drink the soup. (Recorded in the General Record of Iron Utensils within Compendium of Materia Medica)
