（《本经》下品）
【释名】解锡（《本经》）、铅粉（《纲目》）、铅华（《纲目》）、胡粉（弘景）、定粉（《药
性》）、瓦粉（《汤液》）、光粉（《日华》）、白粉（《汤液》）、水粉（《纲目》）、官粉。
弘景曰∶即今化铅所作胡粉也，而谓之粉锡，以与今乖。
时珍曰∶铅、锡一类也，古人名铅为黑锡，故名粉锡。《释名》曰∶胡者，糊也，和脂
以糊面也。
定、瓦言其形，光、白言其色。俗呼吴越者，为官粉；韶州者，为韶粉；辰州者，为辰
粉。
【正误】恭曰∶铅丹、胡粉，实用炒锡造，陶言化铅误矣。
震亨曰∶胡粉是锡粉，非铅粉也。古人以锡为粉，妇人用以附面者，其色类肌肉，不可
入药。
志曰∶粉锡、黄丹二物，俱是化铅为之。英公李 序云铅锡莫辨者，谓此也。按李含光
《音义》云∶黄丹、胡粉皆是化铅，未闻用锡者。《参同契》云∶胡粉投炭中，色坏，还为
铅。《抱朴子·内篇》云∶愚人不信黄丹、胡粉是化铅所作。苏恭以二物俱炒锡作，大误矣。
时珍曰∶锡炒则成黑灰，岂有白粉。苏恭已误，而朱震亨复踵其误，何哉？
【集解】时珍曰∶按《墨子》云∶禹造粉。张华《博物志》云∶纣烧铅锡作粉。则粉之
来亦远矣。今金陵、杭州、韶州、辰州皆造之，而辰粉尤真，其色带青。彼人言造法∶每铅
百斤，熔化，削成薄片，卷作筒，安木甑内，甑下、甑中各安醋一瓶，外以盐泥固济，纸封
甑缝。风炉安火四两，养一七，便扫入水缸内，依旧封养，次次如此，铅尽为度。不尽者，
留炒作黄丹。每粉一斤，入豆粉二两，蛤粉四两，水内搅匀，澄去清水。用细灰按成沟，纸
隔数层，置粉于上，将干，截成瓦定形，待干收起，而范成大《虞衡志》言∶桂林所作铅粉
最有名，谓之桂粉，以黑铅着糟瓮中罨化之。《何孟春余冬录》云∶嵩阳产铅，居民多造
胡粉。其法∶铅块悬酒缸内，封闭四十九日，开之则化为粉矣。化不白者，炒为黄丹。黄
丹滓为密陀僧。三物收利甚博。其铅气有毒，工人必食肥猪犬肉、饮酒及铁浆以厌之。枵腹
中其毒，辄病至死。长幼为毒熏蒸，多痿黄瘫挛而毙。其法略皆不同，盖巧者时出新意，以
速化为利故尔。又可见昔人炒锡之谬。《相感志》云∶韶粉蒸之不白，以萝卜瓮子蒸之则白。
【气味】辛，寒，无毒。权曰∶甘、辛，凉。
时珍曰∶胡粉能制硫黄。又雌黄得胡粉而失色，胡粉得雌黄而色黑，盖相恶也。又入酒
中去酸味，收蟹不沙。
【主治】伏尸毒螫，杀三虫（《本经》）。去鳖瘕，疗恶疮，止小便利，堕胎（《别录》）。
治积聚不消。炒焦，止小儿疳痢（甄权）。治痈肿 烂，呕逆，疗症瘕，小儿疳气（大明）。
止
泄痢、久积痢（宗 ）。治食复劳复，坠痰消胀，治疥癣狐臭，黑须发（时珍）。
【发明】弘景曰∶胡粉金色者，疗尸虫弥良。
藏器曰∶久痢成疳者，胡粉和水及鸡子白服，以粪黑为度，为其杀虫而止痢也。
时珍曰∶胡粉，即铅之变黑为白者也。其体用虽与铅及黄丹同，而无硝盐火烧之性，内
有豆粉、蛤粉杂之，只能入气分，不能入血分，此为稍异。人服食之，则大便色黑者，此乃
还其本质，所谓色坏还为铅也。亦可入膏药代黄丹用。

（收录于《神农本草经》下品）
【释名】解锡（出自《神农本草经》）、铅粉（出自《本草纲目》）、铅华（出自《本草纲目》）、胡粉（陶弘景称）、定粉（出自《药性论》）、瓦粉（出自《汤液经》）、光粉（出自《日华子本草》）、白粉（出自《汤液经》）、水粉（出自《本草纲目》）、官粉。
陶弘景说：就是现在用化铅法制作的胡粉，却称之为粉锡，这与现在的叫法相违背。
李时珍说：铅和锡属于同一类物质，古人把铅称为黑锡，所以命名为粉锡。《释名》中说：胡，通“糊”，是用它调和油脂来涂抹面部。
定、瓦是指它的形状，光、白是指它的颜色。俗称为吴越地区出产的叫官粉；韶州出产的叫韶粉；辰州出产的叫辰粉。
【正误】苏恭说：铅丹、胡粉，实际上是用炒锡制造的，陶弘景说是化铅制作的是错误的。
朱震亨说：胡粉是锡粉，不是铅粉。古人用锡制成粉末，妇女用来敷面，其颜色类似肌肉，不能入药。
苏颂说：粉锡、黄丹这两种东西，都是化铅制成的。英国公李勣在序言中说“铅锡难以分辨”的，指的就是这种情况。按李含光《音义》所说：黄丹、胡粉都是化铅制成的，没听说过用锡做的。《参同契》说：胡粉投入炭火中，颜色毁坏，又还原为铅。《抱朴子·内篇》说：愚蠢的人不相信黄丹、胡粉是化铅制成的。苏恭认为这两样东西都是用炒锡制作的，这是很大的错误。
李时珍说：锡炒制后会变成黑灰，怎么会有白色的粉末呢？苏恭已经错了，而朱震亨又沿袭他的错误，为什么呢？
【集解】李时珍说：按《墨子》记载：大禹制造粉。张华《博物志》记载：商纣王烧炼铅锡制作粉。那么粉的来历也很远久了。现在金陵、杭州、韶州、辰州都生产这种粉，其中辰粉尤其纯正，颜色带青色。当地人讲述制作方法：每用铅一百斤，熔化后，削成薄片，卷成筒状，放入木甑（zèng，古代蒸食器具）内，甑下和甑中各放一瓶醋，外部用盐泥密封加固，用纸封住甑缝。在风炉中放置四两火，养护七天，然后扫入水缸内，依旧密封养护，次次如此，直到铅用完为止。未反应完的铅，留下来炒制成黄丹。每得到一斤粉，加入豆粉二两，蛤粉四两，在水中搅匀，澄清去掉清水。用细灰堆成沟槽，上面隔几层纸，将粉放在纸上，快要干时，截取成瓦片定形的块状，待干后收起。而范成大《虞衡志》说：桂林所产的铅粉最著名，称为桂粉，是将黑铅放在酒糟瓮中覆盖发酵转化而成。《何孟春余冬录》说：嵩阳出产铅，居民多制造胡粉。其方法是：将铅块悬挂在酒缸内，封闭四十九天，打开时就化为粉了。没有变白的部分，炒制成黄丹。黄丹的渣滓成为密陀僧。这三种物品获利非常丰厚。但是铅气有毒，工人必须吃肥猪肉、狗肉，饮酒以及铁浆来压制毒性。空腹吸入毒气，就会生病甚至死亡。老人小孩被毒气熏蒸，大多因痿黄、瘫痪痉挛而死。这些方法大体不同，大概是巧匠们不时创新意，为了快速转化以获取利益罢了。这也可见古人炒锡说法的谬误。《相感志》说：韶粉直接蒸不白，用萝卜瓮子蒸则变白。
【气味】辛味，寒性，无毒。雷敩说：甘味、辛味，凉性。
李时珍说：胡粉能制约硫黄。另外雌黄遇到胡粉会失去颜色，胡粉遇到雌黄会变黑，这是因为它们相互厌恶（药理上的拮抗）。另外，胡粉入酒中去酸味，收捕螃蟹时防止沙子进入。
【主治】治疗伏尸毒虫叮咬，杀灭三虫（出自《神农本草经》）。去除鳖瘕（腹部结块），治疗恶疮，止小便频数，堕胎（出自《名医别录》）。治疗积聚不消。炒焦后，治疗小儿疳积痢疾（甄权）。治疗痈肿溃烂，呕吐逆气，治疗症瘕，小儿疳气（陈藏器）。止泄痢、久积痢（寇宗奭）。治疗食复劳复（病后因饮食或劳累复发），坠痰消胀，治疗疥癣狐臭，使须发变黑（李时珍）。
【发明】陶弘景说：颜色金黄色的胡粉，治疗尸虫效果最好。
孙思邈说：久痢导致疳积的，用胡粉加水及鸡蛋清服用，以大便变黑为限度，因为胡粉能杀虫并止痢。
李时珍说：胡粉，就是铅由黑变白的产物。其体性和用途虽然与铅及黄丹相同，但没有硝盐火烧的性质，内部混有豆粉、蛤粉，只能入气分，不能入血分，这是稍微不同的地方。人服用后，大便变黑的，这是还原了其本质，所谓“色坏还变为铅”。也可以入膏药中代替黄丹使用。

(Recorded in the Lower Grade of *Shennong Bencao Jing*)
**[Names]** Jie Xi (from *Shennong Bencao Jing*), Qian Fen (Lead Carbonate, from *Bencao Gangmu*), Qian Hua (Lead Powder, from *Bencao Gangmu*), Hu Fen (Barbarian Powder, referred to by Tao Hongjing), Ding Fen (Fixed Powder, from *Yaoxing Lun*), Wa Fen (Tile Powder, from *Tangye Jing*), Guang Fen (Luminous Powder, from *Rihua Bencao*), Bai Fen (White Powder, from *Tangye Jing*), Shui Fen (Water Powder, from *Bencao Gangmu*), Guan Fen (Official Powder).
Tao Hongjing stated: This is the Hu Fen made today by processing lead, yet it is called Fen Xi, which contradicts current terminology.
Li Shizhen stated: Lead and tin are of the same category. The ancients called lead "Black Tin" (Hei Xi), hence the name Fen Xi. *Shiming* states: "Hu" sounds like "Hu" (paste), as it was mixed with fat to paste onto the face.
"Ding" and "Wa" refer to its shape; "Guang" and "Bai" refer to its color. Commonly, those from Wu-Yue regions are called Guan Fen; those from Shaozhou are called Shao Fen; those from Chenzhou are called Chen Fen.
**[Correction of Errors]** Su Gong stated: Lead Dan (Lead Tetroxide) and Hu Fen are actually made by roasting tin. Tao's statement that they are made by processing lead is incorrect.
Zhu Zhenheng stated: Hu Fen is tin powder, not lead powder. The ancients used tin powder, which women applied to their faces because its color resembled flesh; it should not be used medicinally.
Su Song stated: Both Fen Xi and Huang Dan are made by processing lead. Li Ji, Duke of Ying, said in his preface that "lead and tin are indistinguishable," referring to this. According to Li Hanguang's *Yinyi*: Huang Dan and Hu Fen are both made by processing lead; there is no record of using tin. *Cantong Qi* states: "When Hu Fen is thrown into charcoal, its color is destroyed, and it returns to lead." *Baopuzi · Inner Chapters* states: "Foolish people do not believe that Huang Dan and Hu Fen are made by processing lead." Su Gong's claim that both are made by roasting tin is a major error.
Li Shizhen stated: Roasted tin turns into black ash; how could it become white powder? Su Gong was already wrong, and Zhu Zhenheng followed his error. Why?
**[Collection and Explanation]** Li Shizhen stated: According to *Mozi*, Yu the Great created powder. Zhang Hua's *Bowuzhi* states: King Zhou of Shang burned lead and tin to make powder. Thus, the origin of powder is ancient. Currently, Jinling, Hangzhou, Shaozhou, and Chenzhou all produce it, with Chen Fen being the most authentic, having a bluish tint. Locals describe the manufacturing method: For every 100 jin of lead, melt it, shave it into thin sheets, roll them into cylinders, and place them inside a wooden steamer (Zeng). Place one bottle of vinegar below and one inside the steamer. Seal the exterior with salt mud and paper. Place four liang of fire in a wind furnace and maintain for seven days. Then sweep the contents into a water vat, reseal, and maintain. Repeat until the lead is exhausted. The unreacted lead is kept and roasted to make Huang Dan. For every jin of powder obtained, add two liang of bean flour and four liang of clam flour, mix evenly in water, and let settle to remove clear water. Make trenches with fine ash, place several layers of paper on top, put the powder on the paper. When nearly dry, cut into tile-shaped blocks. Wait for drying and store. Fan Chengda's *Yuheng Zhi* states: Lead powder produced in Guilin is most famous, called Gui Fen. It is made by placing black lead in a jar of wine lees to ferment and transform. He Mengchun's *Yudong Lu* states: Songyang produces lead, and residents often make Hu Fen. The method is: suspend lead blocks in a wine jar, seal for forty-nine days, and upon opening, it has transformed into powder. The parts that did not turn white are roasted into Huang Dan. The dregs of Huang Dan become Mituo Seng (Litharge). These three items yield great profit. However, lead vapor is toxic. Workers must eat fatty pork or dog meat, drink alcohol, and consume iron slurry to suppress the toxicity. Inhaling the vapor on an empty stomach causes illness and death. Children and adults exposed to the vapor often die from atrophy, jaundice, paralysis, and spasms. These methods differ slightly, likely because skilled craftsmers innovate to accelerate transformation for profit. This also reveals the fallacy of the ancients' claim about roasting tin. *Xianggan Zhi* states: Shao Fen does not turn white when steamed directly, but turns white when steamed in a radon jar.
**[Flavor and Properties]** Pungent, Cold, Non-toxic. Lei Xiao stated: Sweet, Pungent, Cool.
Li Shizhen stated: Hu Fen can restrain Sulfur. Additionally, Realgar loses its color when meeting Hu Fen, and Hu Fen turns black when meeting Realgar, indicating mutual aversion (pharmacological antagonism). Furthermore, adding Hu Fen to wine removes acidity, and it prevents sand from entering crabs during capture.
**[Indications]** Treats poisoning from hidden corpse toxins and insect stings; kills three types of parasites (from *Shennong Bencao Jing*). Removes abdominal masses (Nie Xia), treats malignant sores, stops frequent urination, induces abortion (from *Mingyi Bielu*). Treats accumulation that does not dissipate. Charred, it treats infantile malnutrition dysentery (Zhen Quan). Treats carbuncles and ulcers, vomiting and regurgitation, abdominal masses, and infantile malnutrition qi (Chen Cangqi). Stops diarrhea and dysentery, chronic accumulated dysentery (Kou Zongshi). Treats relapse due to diet or fatigue, descends phlegm and reduces distension, treats tinea and fox odor, darkens beard and hair (Li Shizhen).
**[Elucidation]** Tao Hongjing stated: Golden-colored Hu Fen is best for treating corpse worms.
Sun Simiao stated: For chronic dysentery leading to malnutrition, take Hu Fen mixed with water and egg white. Stop when stool turns black, as it kills parasites and stops dysentery.
Li Shizhen stated: Hu Fen is lead transformed from black to white. Although its nature and use are similar to lead and Huang Dan, it lacks the property of nitrate/salt burning. It contains mixed bean flour and clam flour, entering only the Qi level, not the Blood level, which is a slight difference. After human ingestion, if stool turns black, this is returning to its original essence, as stated: "color destroyed, returns to lead." It can also be used in plasters instead of Huang Dan.
**[Attached Prescriptions]** Fourteen old prescriptions, thirty new prescriptions.
Relapse due to overexertion or diet, near death: Take a small amount of Hu Fen with water (*Zhouhou Beiji Fang*).
Infantile spleen diarrhea unceasing: Remove pits from twenty red dates, insert Official Powder inside, bake dry on yin-yang tiles, remove dates and grind to powder. Take three qian each time, with rice soup (*Sun Taoren Ji Xiao Fang*).
