补阳
甘温。阳明（胃）气分药。木石之精。强阴益阳，通百节，利九窍，补虚劳，下乳汁。
服之令人阳气暴充，饮食倍进，形体壮盛。然其性 悍，须命门真火衰者可偶用之。若借以
恣欲，多服、久服，不免淋浊痈疽之患。出洞穴中，石液凝成，下垂如冰柱。通中轻薄、如
鹅翎管、碎之如爪甲光明者真。炼合各如本方，蛇床为使。恶牡丹、紫石英。忌参、术、羊
肉、葱、蒜、胡荽。
重，润肺
甘辛微温。肺、大肠经气分之药。润以去燥，利小便，实大肠。治肺痿吐脓，咳逆上气
。但系石类，祗可暂用（《十剂》曰∶湿可去枯，白石英、紫石英之属是也。湿，即润也。
按∶润药颇多，石药终燥，而徐之才取二石英为润剂，存其意可取）。白如水晶者良。
重，镇心，润，补肝
甘平。性温而补，重以去怯，湿以去枯。入心、肝血分，故心神不安，肝血不足，女子
血海虚寒不孕者宜之（冲为血海，任主胞胎。《经疏》云∶女子系胞于肾及心包络，虚则风
寒乘之，故不孕。紫石英辛温，走二经，散风寒，镇下焦，为暖子宫之要药）。色深紫莹彻
，五棱。火 、醋淬七次，研末水飞用。二英俱畏附子。恶黄连（石英五色，各入五脏）。
重，解毒，杀虫
辛温有毒。得正阳之气，入肝经气分。搜肝强脾，散百节大风，杀百毒，辟鬼魅。治惊
痫痰涎，头痛眩晕，暑疟 痢，泄泻积聚（虞雍公道中冒暑，泄痢连月，梦至仙居，延之坐
。壁中有词云∶暑毒在脾，湿气连脚，不泄则痢，不痢则疟。独炼雄黄，蒸饼和药，甘草作
汤，食之安乐。别作治疗，医家大错。如方服之遂愈）。又能化血为水，燥湿杀虫，治劳疳
疮疥蛇伤。赤似鸡冠，明彻不臭，重三五两者良。醋浸，入莱菔汁煮，干用。生山阴者名雌
黄，功用略同。劣者名熏黄，烧之则臭，只堪熏疮疥，杀虫虱。
Tonifying Yang (Zhuru, Stalactite)
Sweet and warm. A herb acting on the Qi level of the Yangming channel (Stomach). It is the essence condensed from wood and stone. It strengthens Yin, benefits Yang, unblocks all joints, opens the nine orifices, tonifies deficiency and consumptive diseases, and promotes lactation.
Taking it causes a sudden surge of Yang Qi, significantly increases food intake, and makes the physique robust and vigorous. However, its nature is fierce; it should only be used occasionally when the True Fire of the Mingmen (Gate of Life) is deficient. If used to indulge in lust, excessive or long-term consumption inevitably leads to disorders such as stranguria, turbid urine, carbuncles, and sores. It originates from caves, formed by the condensation of liquid stone, hanging down like icicles. Those that are hollow, thin and light, resembling goose quills, and break open with a shine like fingernails are genuine. Refining and compounding should follow the methods specified in this text, using Cnidii Fructus (Shechuangzi, 蛇床子) as an guiding agent. It is incompatible with Paeoniae Radix Rubra (Mudanpi, 牡丹皮) and Fluminis Lapis (Zi Shiyun, 紫石英). Dietary restrictions include Ginseng Radix et Rhizoma (Renshen, 人参), Atractylodis Macrocephalae Rhizoma (Baizhu, 白术), mutton, Allium Fistulosum (Congbai, 葱), Allium Sativum (Suan, 蒜), and Coriandri Fructus (Huxu, 胡荽).
Heavy, Moistening the Lung (Bai Shiyin, White Quartz)
Sweet, pungent, and slightly warm. A herb acting on the Qi level of the Lung and Large Intestine channels. Its moistening property removes dryness, promotes urination, and consolidates the Large Intestine. It treats lung abscess with purulent sputum, cough, and rebellious Qi. However, being a mineral substance, it can only be used temporarily (The *Ten Categories* states: "Moistening agents can remove dryness; Bai Shiyin and Zi Shiyin belong to this category. 'Moist' here refers to 'moistening'. Note: There are many moistening herbs, but mineral drugs are ultimately drying. Xu Zhicai selected these two quartzes as moistening agents; preserving this intent is worthwhile"). Those white as crystal are of good quality.
Heavy, Calming the Heart, Moistening, Tonifying the Liver (Zi Shiyin, Purple Quartz)
Sweet and neutral. Its nature is warm and tonifying; its heaviness dispels fear, and its moisture removes dryness. It enters the Blood level of the Heart and Liver channels. Therefore, it is suitable for those with unsettled Heart Spirit, insufficient Liver Blood, and women suffering from infertility due to deficiency-cold in the Sea of Blood (The Chong vessel is the Sea of Blood, and the Ren vessel governs conception. *Jing Shu* states: The uterus is connected to the Kidney and Pericardium; deficiency allows Wind-Cold to invade, causing infertility. Zi Shiyin is pungent and warm, traversing these two channels, dispersing Wind-Cold, calming the Lower Jiao, and serving as a key herb for warming the uterus). Those with a deep purple color, transparent and crystalline, having five facets are preferred. Calcine over fire, quench in vinegar seven times, grind into powder, and process by water levigation. Both quartzes are wary of Aconiti Lateralis Radix Praeparata (Fuzi, 附子). They are incompatible with Coptidis Rhizoma (Huanglian, 黄连) (Quartz comes in five colors, each corresponding to the Five Zang organs).
Detoxifying, Killing Parasites (Xionghuang, Realgar)
Pungent and warm, toxic. It receives pure Yang Qi and enters the Qi level of the Liver channel. It searches out Liver pathogens, strengthens the Spleen, disperses severe Wind affecting all joints, kills various toxins, and repels malevolent spirits. It treats convulsions, epilepsy, and phlegm-saliva accumulation, headache, vertigo, summerheat malaria and dysentery, diarrhea, and accumulations (Yu Yonggong encountered summerheat while traveling, suffering from diarrhea and dysentery for months. He dreamed of a celestial abode where he was invited to sit. Words on the wall read: "Summer-heat toxin resides in the Spleen, dampness connects to the feet; if not diarrhea, then dysentery; if not dysentery, then malaria. Only refined Xionghuang, mixed with steamed dough pills, and taken with Licorice decoction brings peace and joy. Other treatments are major errors." Following this prescription led to recovery). It can also transform blood into water, dry dampness, kill parasites, and treat consumptive diseases, infantile malnutrition, sores, scabies, and snakebites. Those red like a rooster's comb, bright and clear without odor, weighing three to five taels, are of good quality. Soak in vinegar, boil with Raphani Fructus juice, and use dried. Those growing in the shade of mountains are called Niu Huang (Yinghuang, Arsenolite), with similar functions. Inferior quality is called Xun Huang, which smells foul when burned and is only suitable for fumigating sores and killing lice.
