礞石（专门入肝经）。禀受石头中刚猛的性质，质地沉重而下坠，味道辛且咸，颜色青、气味平。其功效专门入肝以平抑肝木之气，具有下气的作用，是治疗惊风、利化痰浊的重要药物。（喻嘉言说：“惊风”这两个字，是古人凭空捏造的谬论。不知道小儿初生以及儿童时期，肌肉、筋骨、脏腑、血脉都尚未发育成熟，阳气相对有余，阴气相对不足，所以容易产生内热。热势严重则生风、生惊，这也是常有的事。后人不能理解，便认为这是奇特的疾病，并且说这种病有八种证候：因为看到患儿摇头、手部动作异常，就创立了“抽掣”的名称；因为看到突然牙关紧闭、脚部痉挛拘急，就创立了“目斜乱搐搦”的名称；因为看到脊柱僵硬、背部反折，就创立了“角弓反张”的名称。这种说法流传已久，不知是妄加造作。遇到这些病症，人们无不认为是奇特之病，却不知道小儿腠理不致密，容易感受风寒邪气，患病后导致筋脉牵强。由于筋脉牵强才出现抽掣、搐搦、角弓反张等种种不通畅的症状和名称。然而却使用金石类药物来镇坠外邪，致使邪气深入脏腑，往往百发百死。偶尔有体质强壮、病情轻微而痊愈的，又被惊诧地称为再造奇功。于是导致各守专科门户之见，虽然每天杀死数名婴儿，却不知道自己犯了罪过。）大概是因为风木之气太过，导致脾土受到克制，气机不能运化，积滞之气生成痰浊，壅塞在膈上，变化生出风热。治疗适宜用此药重坠下行泄热，则风木之气得以平复，而痰积自然消除。现在人使用王隐君制作的滚痰丸，其中含有礞石，通治各种怪异的痰症，这非常不妥。（滚痰丸配方：礞石、焰硝各二两，研碎后用水飞法处理净得一两；大黄用酒蒸制八两；黄芩用酒洗制八两；沉香五钱。研为细末，用水泛丸。）不知道痰浊是因为热盛所致，风木挟带热邪而脾失健运，所以痰积像胶漆一样黏稠。使用此药确实符合病机。但是如果脾胃虚弱，饮食减少、大便溏薄，服用此药会导致泄泻不止。小儿服用后，多会演变成慢性重症，以致束手待毙。能不谨慎吗？硝石需水飞研用。
(Shi) Clears phlegm-heat in the liver and diaphragm.
Mengshi (Lapis Auripigmenti / Realgar? *Note: In TCM context, Mengshi usually refers to Qingmengshi - Flaked Pyrite or similar mineral, specifically "Qingmengshi" is often translated as Flaked Pyrite or simply Mengshi. Given the description "stone-like", "heavy", "blue-green color", it aligns with Qingmengshi (Flaked Pyrite). However, strictly following WHO/standard herb names, Mengshi is often kept as Mengshi or translated descriptively. Let's use Mengshi (Flaked Pyrite)*). It possesses the fierce nature of stone, is heavy and sinking, descending in action. Its taste is pungent and salty, its color is green, and its qi is neutral. Its function specializes in entering the Liver to calm Wood, descends Qi, and is an essential herb for treating convulsions and promoting expectoration. (Yu Jiayan said: The term "Jingfeng" [Convulsive Disease] is a baseless fabrication by ancients. They did not realize that newborn infants and young children have muscles, bones, tendons, zang-fu organs, and blood vessels that are not yet fully developed. Their Yang is relatively excessive while their Yin is insufficient, making them prone to generating heat. When heat becomes severe, it generates Wind and Convulsions, which is quite common. Later generations failed to understand this, regarding it as a peculiar disease. Furthermore, they claimed there were eight signs: because the child shakes their head and moves their hands, they coined the name "Chouche" [Twitching/Clonic movements]; because the child suddenly has clenched jaws and cramped legs, they coined the name "Muxie Luanchuo Nuo" [Deviation of eyes and chaotic twitching/spasms]; because the child has a stiff spine and arched back, they coined the name "Jiaogong Fanzhang" [Opisthotonos]. This tradition persisted for a long time, unknown to be a false creation. Upon encountering such symptoms, people invariably regarded them as peculiar diseases, unaware that children's couli [pores/skin texture] are not dense, making them susceptible to Wind-Cold invasion. Illness causes tension in the sinews and vessels. Due to this tension, symptoms like twitching, spasms, and opisthotonos arise—various incomprehensible names and conditions. Yet, metallic and stony minerals are used to suppress external pathogens, driving them deep into the zang-fu organs. This results in death in nearly every case. Occasionally, those with strong constitutions and mild symptoms recover, and this is marvelously hailed as a miraculous feat of resurrection. Consequently, practitioners cling to their specialized views; although they kill several children daily, they remain unaware of their guilt.) Generally, when Wood-Wind is excessive, Spleen-Earth is constrained, Qi fails to transform and transport, leading to accumulated Qi generating Phlegm. This Phlegm obstructs the upper diaphragm, transforming into Wind-Heat. Treatment should employ this heavy, sinking, and purgative herb to calm the Wood-Wind Qi, thereby naturally eliminating the Phlegm accumulation. Nowadays, people use Mengshi in Wang Yinjun's Guntan Wan [Rolling Phlegm Pill] to treat all kinds of bizarre phlegm disorders, which is highly inappropriate. (Guntan Wan Formula: Mengshi and Yanxiao [Saltpeter/Niter] each 2 liang, ground and purified via water flotation to obtain 1 liang pure powder; Dahuang [Rhubarb Root and Rhizome] steamed with wine 8 liang; Huangqin [Scutellaria Root] washed with wine 8 liang; Chenxiang [Aquilaria Wood] 5 qian. Ground into fine powder and formed into pills with water.) One must not realize that Phlegm arises from excessive Heat, where Wood-Wind carries Heat causing Spleen dysfunction, resulting in Phlegm accumulation as sticky as glue or lacquer. Using this herb is indeed appropriate for such cases. However, if the Spleen and Stomach are weak, with poor appetite and loose stools, taking this purgative will cause incessant diarrhea. If taken by children, it often leads to chronic critical conditions, resulting in helplessness awaiting death. Can one not be cautious? Xiaoshi [Niter/Saltpeter] should be processed via water flotation and ground.
