粉锡（出自《神农本草经》）主治伏尸毒螫，杀灭三虫。（以上为朱笔标注，引自《神农本草经》）去除鳖瘕，治疗恶疮，堕胎。主治小便不利。（以上为黑字标注，为名医所记录）
【名称】解锡、定粉、胡粉。
【产地】陶隐居说：就是现在用化铅制成的胡粉，却称之为粉锡，这与经典记载相违背。（《唐本草注》说：铅丹和胡粉实际上是用锡制造的，陶弘景说是化铅做的，《本经》说粉锡也是错误的。）○谨按李含光说：黄丹和胡粉这两种物质都是化铅制成的，没听说过用锡的。所以苏恭赞同契的说法说：如果把胡粉投入炭火中，颜色变坏变成铅。《抱朴子·内篇》说：愚昧的人竟然不相信黄丹及胡粉是化铅所制作的。唉！古人或许是将铅和锡兼称吧？所以英公序言说“铅锡莫辩”大概就是指这个意思。唐代注疏因袭错误，于是将这三种东西都说是炒锡所致，这真是很大的误解了。再仔细思考，陶弘景的说法是正确的。现在制造粉的方法：用砖砌成灶，高五六尺，中间砌一个小缸，装入糟醋至八分满。用竹篦平放在缸口，篦底用木头做成井字架。使用蜀郡平泽的铅，不限分量，熔化成汁，用勺子倒入铁掀模内制成方片，每片重二十两，共三百片。将这些铅片攒积在竹篦上，用酱蓬覆盖缸底，用重一斤的炭墼煨火，日夜各烧两个饼的时间，使醋气熏蒸在上面。等到经过十四天夜晚，醋已耗尽，将铅片上浮起的粉击取下来，称重后放入盛水的缸中，仍带着水细细过滤澄清于另一个缸中。去掉上面的清水，以粉三百斤为标准，加入白盐一斤、福蜜四两，两种味道混合炼熟，稍微澄清过滤后倒入粉中使其均匀。外面做一个炕，上面铺一层细砂土，再用绵纸严密遮盖土壤，将粉摊在纸上。炕下仍然煨着炭墼微火，辗转翻动，将近一个月才干燥。用竹刀切成块状。冬季水寒，不宜制作。
【用法】以光亮细腻者为佳。
【颜色】白色。
【味道】辛。
【性质】寒。
【气味】气薄，属于阳中之阴。
【气味】腥。
【炮制】研细使用。
【主治】（疗）（《别录》说）主治从高坠落导致的瘀血抢心，面色青紫，短气欲死，用胡粉一钱匕，和水服用，即可痊愈。治疗干湿癣及狐臭，如果大腿内侧或阴部经常潮湿且发臭，或者形成疮疡，只用胡粉涂抹即可痊愈，常用且非常有效。小儿夜啼，用水调服三豆大小的量，每日三次服用，有效。
【合治】胡粉和水调和，配合鸡蛋清服用，治疗小儿久痢发展成疳积，服用直到大便变黑为止，这是为了杀虫并止痢。○与炭灰等分，用油脂调和涂抹，治疗孔窍上的疮，疮中的水流即止。○与羊髓调和涂抹，治疗火烧伤。○与猪骨髓调和，治疗小儿舌上疮，每日敷三次，有效。○熬制八分量的胡粉，配合猪脂涂抹小儿疳疮，以痊愈为度。○与盐一起熬制，颜色改变后，摩擦小儿腹部，治疗腹胀及腹皮发青，如果不及时处理，片刻就会死亡。○与土调和涂抹，治疗小儿耳后的月蚀疮。
【禁忌】孕妇不可服用。
【解毒】硫黄。
Non-toxic.
Fenxi (derived from *Shennong Bencao Jing* [Divine Farmer's Materia Medica]) primarily treats "fusshi" (latent corpse poison/stings), eliminates the three parasites (annotated in red ink, from *Shennong Bencao Jing*). It removes "biejia" (abdominal masses resembling turtles), treats malignant sores, and induces abortion. It treats difficult urination (annotated in black ink, recorded by famous physicians).
[Names] Jiexi, Dingfen, Hufen.
[Origin] Tao Hongjing stated: This is currently made by smelting lead into Hufen, yet it is called Fenxi, which contradicts the classic text. (*Tang Bencao Zhu* [Tang Dynasty Commentary on Materia Medica] states: Qiandan [Lead Tetroxide] and Hufen are actually made from tin; Tao's claim that they are made from smelted lead, and the *Benjing*'s statement that Fenxi is also an error, are incorrect.) ○ According to Li Hanguang: Both Huangdan [Lead Tetroxide] and Hufen are made by smelting lead; there is no record of using tin. Therefore, Su Gong agreed with Qie's view: if Hufen is thrown into charcoal, its color deteriorates and turns into lead. *Baopuzi Neipian* [Inner Chapters of the Master Who Embraces Simplicity] states: Fools do not believe that Huangdan and Hufen are made from smelted lead. Alas! Perhaps ancients referred to lead and tin collectively? Thus, Ying Gong's preface mentions "indistinguishable lead and tin," likely referring to this. The Tang commentary inherited this error, claiming all three substances were caused by stir-frying tin, which is a significant misunderstanding. Upon careful consideration, Tao's explanation is correct. The current method of manufacturing powder: Build a kiln with bricks, five or six chi high, with a small vat built in the center. Fill the vat eight-tenths full with fermented grains and vinegar. Place a bamboo sieve flat over the mouth of the vat. Under the sieve, construct a cross-shaped wooden frame. Use lead from Pingze in Shu Commandery, without fixed quantity limits. Melt the lead into liquid, pour it into iron molds using a ladle to make square sheets, each weighing twenty liang, totaling three hundred sheets. Accumulate these lead sheets on the bamboo sieve. Cover the bottom of the vat with Jiangpeng (a type of plant fiber cover). Use charcoal bricks weighing one jin for slow heating, burning two "bing" (cakes) worth of fuel day and night, allowing vinegar fumes to steam upwards. After fourteen days and nights, when the vinegar is exhausted, scrape off the powder floating on the lead sheets. Weigh the collected powder and place it in a water-filled vat. Filter and clarify it finely through another vat while retaining some water. Discard the clear water on top. Based on three hundred jin of powder, add one jin of white salt and four liang of Fu mi (blessing honey). Mix and refine until uniform. Clarify slightly and filter into the powder to ensure even distribution. Construct an external drying kiln, spread a layer of fine sand soil inside, and tightly cover the soil with cotton paper. Spread the powder on the paper. Keep low heat from charcoal bricks under the kiln, turning the powder frequently. It takes nearly one month to dry completely. Cut into blocks with a bamboo knife. Production is not suitable in winter due to cold water.
[Usage] Bright and smooth texture is preferred.
[Color] White.
[Taste] Acrid (Xin).
[Nature] Cold.
[Qi Property] Thin Qi, belonging to Yin within Yang.
[Odor] Fishy.
[Processing] Grind into fine powder before use.
[Indications] (Treatment) (*Bielu* states): Primarily treats blood stasis rushing to the heart following a fall from height, presenting with cyanotic complexion, shortness of breath, and near-death sensation. Administer one qianbi of Hufen mixed with water, and recovery will occur. Treats dry and damp tinea (ringworm) and fox odor (bromhidrosis). If the inner thighs or genital area are constantly moist and foul-smelling, or if ulcers form, applying only Hufen locally will cure it. This method is commonly used and highly effective. For infantile nocturnal crying, mix with water and administer an amount equivalent to three beans, three times daily, which is effective.
[Compound Therapies] Mix Hufen with water and egg white, and administer to treat chronic dysentery in children progressing to malnutrition syndrome (gan accumulation). Continue administration until stools turn black, aiming to kill parasites and stop diarrhea. ○ Mix equal parts of Hufen and charcoal ash, blend with fat/lard, and apply to treat sores on orifices; discharge from the sore will cease. ○ Mix with sheep marrow and apply to treat burns. ○ Mix with pig bone marrow and apply to treat oral ulcers in children; apply three times daily for effectiveness. ○ Heat eight parts of Hufen, mix with lard, and apply to treat gan sores in children; discontinue when healed. ○ Heat with salt until the color changes, then rub onto the child's abdomen to treat abdominal distension and cyanosis of the abdominal skin. If untreated, death may occur shortly. ○ Mix with earth/clay and apply to treat "moon-eating sores" (angular cheilitis or perioral dermatitis) behind the ears in children.
[Contraindications] Do not take during pregnancy.
[Antidote] Realgar (Sulfur).
