牛黄：
味苦，性平，无毒，归入心经。主治成年人癫狂发作、中风导致的痰壅不语，小儿惊痫及天吊风（一种以颈项强直、角弓反张为特征的儿科急症），客忤（外邪侵袭引起的惊恐痉挛）口噤（牙关紧闭），能驱除邪气鬼魅，安定魂魄，且具有堕胎功效。真品牛黄应当质地轻微、气味芳香，研磨后颜色通透，置于舌上先苦后甘，清凉感透入心胸。用人参作为引经药，畏龙骨、地黄、龙胆、蜚蠊（蟑螂）、常山，恶牛膝、干漆。
按语：牛黄味苦，适宜归入心部，癫狂等症状为何不归属于心？若有不愈者，是何原因呢？
雷公云：凡使用牛黄有四种情况。第一种是“生神黄”，是通过欺骗手段获得的；第二种是“角黄”，是从牛角中取得的；第三种是“心黄”，是病死的牛，识货的人将其剥开取出心脏，其黄位于心中，如同浓稠的黄酱汁，采集后立即放入水中保存，沾水后的牛黄像碎蒺藜子一样，有的如豆子大小，有的如帝珠子般圆润；第四种是“肝黄”，在牛身上表现为眼睛光亮如血色，时常鸣叫吼声，照水时皮肤有光泽，因恐惧人而逃窜，或者被人另外采集，据说可能有神妙之事。凡是炮制前需先捣细研成尘状，用绢布包裹，再用黄嫩牛皮包裹，放置在井面上，距离水面三四尺远，放置一夜，天亮后方可取用。
麝香：
味辛，性温，无毒，归入十二经。主治恶气鬼邪、蛇虺蛊毒、惊悸痈疽、中恶心腹暴痛胀满、目中翳膜、泪眵风毒、温疟痫证，能通关窍，杀蛊虱，催生及堕胎，忌食大蒜。
按语：麝香是各种香料中最珍贵的，其气透入骨髓，因此在经络中没有不能到达的地方。然而辛香类药物，必定会耗损真元，使用时需谨慎。
雷公云：凡使用麝香多有伪品，不如不用。其香气分三等：第一名“遗香”，是幼崽脐带闭合饱满时，自己在石头上用蹄尖剔出，掉落处一里内草木不生，并呈焦黄色，人若取得此香，价格与珍珠相同。第二名“脐香”，采集后非常堪用。第三名“结香”，被大兽追逐，惊恐畏惧坠地而死，被人收得后剖开，见心血在脾上，结成一块干血块，不堪入药。凡使用麝香勿靠近火源或日光，应在磁钵中细细研磨后任用。
Bile Calculus Bovis (Niuhuang):
Taste: Bitter. Nature: Neutral. Toxicity: Non-toxic. Meridian Tropism: Heart Meridian. Indications: Mainly treats mania and madness in adults, aphasia due to phlegm obstruction in stroke, infantile convulsions and Tian Diao syndrome (a pediatric emergency characterized by neck stiffness and opisthotonos), Ke Wu (sudden fright/spasm caused by external pathogens) with lockjaw, expels evil spirits, stabilizes the soul and calms the spirit, and can induce abortion. Authentic Bile Calculus Bovis should be light in texture, fragrant, transparent in color when ground, bitter first then sweet on the tongue, with a cooling sensation penetrating the heart. Ginseng Radix et Rhizoma (Renshen) is used as an guiding herb. It is incompatible with Os Draconis (Longgu), Rehmanniae Radix (Dihuang), Gentianae Radix (Longdan), Blatta orientalis (Feilongchang), Dichroae Radix (Changshan), and fears Achyranthis Bidentatae Radix (Niuxi) and Xanthii Fructus immitis processed with dry lacquer (Ganqi).
Commentary: Bile Calculus Bovis is bitter and suitable for entering the Heart organ. Why do mania and similar symptoms not belong to the Heart? If there are cases that are not cured, what is the reason?
Lei Gong states: There are four types when using Bile Calculus Bovis. The first is "Sheng Shen Huang" (Living Divine Yellow), obtained through deception; the second is "Jiao Huang" (Horn Yellow), taken from the horn; the third is "Xin Huang" (Heart Yellow), from a cow that died of illness. Those who recognize it will slaughter the cow, open the chest to take the heart. The bile inside the heart resembles thick yellow sauce. Upon collection, it must be stored immediately in water. After touching water, the bile forms particles like broken Tribulus seeds, some bean-sized, others like imperial pearls. The fourth is "Gan Huang" (Liver Yellow). On the cow, it manifests as eyes bright red like blood, frequent roaring, shiny skin when reflecting in water, fleeing from fear of humans, or collected separately by others, said to have miraculous properties. Before processing, it must be finely ground into dust, wrapped in silk, then wrapped in fresh yellow cowhide, placed over a well surface at a distance of three to four chi from the water, left overnight, and used only at dawn.
Musk (Shexiang):
Taste: Pungent. Nature: Warm. Toxicity: Non-toxic. Meridian Tropism: Enters all twelve meridians. Indications: Mainly treats malignant qi and evil spirits, snake venom and gu poison, palpitations and fright, carbuncles and sores, sudden abdominal pain and distension due to central cold/evil, corneal opacity in eyes, excessive tearing and wind toxicity, warm malaria and epilepsy, opens orifices, kills parasites and lice, induces labor, and induces abortion. Avoid garlic.
Commentary: Musk is the most precious of all aromatic substances. Its aroma penetrates to the bone marrow, thus entering all meridians without exception. However, pungent and aromatic preparations inevitably consume the true yuan (vital essence), so they must be used with caution.
Lei Gong states: There are many counterfeit musks available, so it is better not to use them if authenticity cannot be guaranteed. The quality of musk is divided into three grades: The first grade is "Yi Xiang" (Lost Fragrance), which is excreted by young calves when their umbilical cords close tightly, scraped out by their own hooves on stones. Wherever it falls, grass and water fail to grow within one li, and it appears scorched yellow. If obtained, its price equals that of pearls. The second grade is "Qi Xiang" (Umbilical Fragrance), which is very suitable for medicinal use after collection. The third grade is "Jie Xiang" (Knot Fragrance), resulting from a calf being chased by large beasts, dying of fright and falling. When collected and opened, blood and heart tissue are found on the spleen, forming a dried blood clot, which is unsuitable for medicine. When using Musk, avoid fire and direct sunlight. It should be finely ground in a porcelain mortar before use.
