\r雌黄\pj408.bmp\r
味辛、甘，气平、寒。有毒。产武都山阴，故雌黄为誉。色与金子仿佛，因受金精熏
蒸。（阴山出金故也。）甲错层层，又若云母。凡修制主疗，忌鸡犬妇人。倘误触之，则黑如
铁。
研成尘末，治外功多。入药最稀，服者宜审。去身面白 ，一切恶疮；散皮肤死肌，诸般虫
毒。辟邪去恶，并与雄同。怀孕佩身，转男成女。若以草药伏住，亦可点铜成银。（照前法
，以草药伏住火，胎色不移。谓熔成汁者，点银成金，点铜成银。）
\r赤石脂\pj409.bmp\r
味甘、酸、辛，气温。无毒。多产泰山，无时收采。种有五色，实共一名。虽各补
脏不同，总系收敛之剂。可以隅反，不必概言。形赤粘舌为良，火 醋淬才研。畏芫花莫见
，恶大黄松脂。凡百溃汤收口长肉，但诸来血止塞归经。养心气涩精，住泻痢除痛。（白者
入大肠经，止泻尤妙。）
\r凝水石\pj410.bmp\r
（即寒水石） 味辛、甘，气寒。无毒。多生河间，（郡名。）亦产邯郸。（即赵郡。）有
纵理横理不同，惟润泽清明为上。置水中与水一色。虽夏月亦凝为水，故此得凝水之名，必
须研极细才用。服加姜汁，性恶地榆。却胃中热，及五脏伏热齐驱；解巴豆毒，并丹石诸
毒并压。伤寒劳复兼治，积聚邪热亦除。止烦闷喉颡渴消，去水肿小腹顽痹。
【雌黄】
味辛、甘，气平、寒。有毒。产于武都山北坡，因此雌黄享有盛誉。颜色与金子相似，是因为受到金精气的熏蒸。（因为阴山出产黄金的缘故。）质地层层如鳞甲交错，又像云母一样。凡是炮制和主治方面，忌讳鸡、狗和妇女接触。如果误触，颜色就会变得像铁一样黑。
研成粉末，外用功效较多。入药使用很少，服用者应当审慎。去除面部白翳（或指皮肤白斑/瑕疵），治疗各种恶疮；消散皮肤上的死肌，解除各类虫毒。辟邪去恶，作用与雄黄相同。孕妇佩戴在身上，会使怀男胎转为女胎。如果用草药进行“伏制”（降低毒性或改变性质）处理，也可以用来点化铜变成银。（按照前面的方法，用草药伏制火性，使金属胎色不改变。意思是熔化成汁后，可以点银成金，点铜成银。）
【赤石脂】
味甘、酸、辛，气温。无毒。多产于泰山，随时可以采收。品种有五色，但实际共用一个名字。虽然各自补益脏腑的功能不同，总体都属于收敛类药物。可以举一反三，不必一一详述。形状红色且粘舌的为佳品，需用火烧红后浸入醋中淬炼，然后才能研磨。害怕芫花，厌恶大黄和松脂。凡是各种溃疡汤剂收口长肉，以及各种出血止血归经的情况，都能发挥作用。滋养心气，固涩精气，止住泻痢，消除疼痛。（白色的赤石脂进入大肠经，止泻效果尤其好。）
【凝水石】
（即寒水石） 味辛、甘，气寒。无毒。多产于河间（郡名），也产于邯郸（即赵郡）。有纵理和横理的不同，以润泽清明为上品。放入水中与水同色。即使在夏天也能凝结成水，因此得名凝水石，必须研磨得极细才可使用。服用时加入姜汁，其性畏忌地榆。清除胃中的热邪，以及五脏潜伏的热邪一并驱除；解巴豆毒，并压制丹石类药物引起的各种中毒。伤寒病愈后因劳累复发兼治，积聚的邪热也能清除。止烦闷、咽喉口渴消渴，去除水肿和小腹顽痹。
[Realgar (Orpiment)]
Taste: Acrid, Sweet. Nature: Neutral, Cold. Toxicity: Toxic. Origin: Produced on the north slope of Wudu Mountain, hence Orpiment enjoys a high reputation. Color resembles gold because it is steamed by the essence of metal (since Yin Mountain produces gold). Texture is layered like fish scales, resembling mica. Regarding processing and treatment, it must avoid contact with chickens, dogs, and women. If accidentally touched, it turns black as iron.
Ground into powder, it is used mostly externally. Rarely used internally; users should exercise caution. Removes white films from the eyes (or skin blemishes), treats all kinds of malignant sores; dissipates dead muscle in the skin, resolves various insect poisons. Expels evil influences, acting similarly to Realgar (Arsenolite). Pregnant women wearing it may cause a male fetus to turn female. If processed ("Fu") with herbal medicines, it can also transmute copper into silver. (Following the previous method, using herbs to control fire properties so that the metallic body color remains unchanged. Meaning after melting into liquid, it can transmute silver into gold, and copper into silver.)
[Red Kaolin]
Taste: Sweet, Sour, Acrid. Nature: Warm. Toxicity: Non-toxic. Origin: Mostly produced in Mount Tai, collectible at any time. Varieties include five colors but share one name. Although their functions in tonifying different organs vary, they generally belong to astringent agents. One can infer others from these examples, so detailed explanation is unnecessary. Red color and adhesion to the tongue indicate quality; it must be calcined in fire, quenched in vinegar, and then ground. It fears Kansui (Radix Euphorbiae Kansuensis) and dislikes Rhubarb (Radix et Rhizoma Rhei) and Pine Resin. For healing ulcers and promoting flesh growth in various decoctions, and for stopping bleeding and returning blood to its vessels, it is effective. Nourishes Heart Qi, secures Essence, stops diarrhea and dysentery, relieves pain. (White variety enters the Large Intestine Meridian, especially effective for stopping diarrhea.)
[Ning Shui Shi / Cold Water Stone]
(Also known as Han Shui Shi / Cold Water Stone) Taste: Acrid, Sweet. Nature: Cold. Toxicity: Non-toxic. Origin: Mostly produced in Hejian (Commandery name), also produced in Handan (i.e., Zhao Commandery). There are differences between longitudinal and transverse grain structures; those that are moist, clear, and bright are superior. When placed in water, it takes on the same color as water. Even in summer, it appears congealed like water, hence the name Ning Shui Shi. It must be ground extremely fine before use. Add ginger juice when taking; its nature opposes Sanguisorba Root (Radix Sanguisorbae). Clears heat in the Stomach and drives out latent heat in the Five Zang Organs; resolves Croton Seed (Fructus Crotonis) toxicity and suppresses various toxicities caused by mineral drugs (Dan Shi). Treats complications of cold damage due to overexertion; eliminates accumulated pathogenic heat. Stops irritability, throat thirst, and Xiao Ke (Wasting-Thirst); removes edema and stubborn bi-syndrome in the lower abdomen.
