甘温，无毒。出泰山。以六棱莹白如水晶者为真。林北海先生《本草纲目必读
》，但收紫而不及白，世鲜真者可知。
《本经》治消渴，阴痿不足，咳逆，胸膈间久寒，益气除风湿痹。
发明 白石英入手太阴、足阳明气分，肺痈溃久，痿痹不起者宜之。《本经》主消渴阴
痿不足诸病，功专温肺无疑。但石性 悍，不可久服。仲景《金匮》风引汤只令碎如米粒
，不欲其滓入胃也。《千金》五石等方，俱 过水飞入丸，而五石丸专以钟乳为君，合紫白
石英、赤石脂、石膏，专温脏气，而石膏清胃，以解诸石之悍，且既经 过水飞，不虑其滓
之留中蕴热也。
甘温，无毒。出泰山。以五棱明净深紫大块者良，浙产者块小亦可入药。经火
则毒生，研极细水飞三次用。时珍云∶ 赤，醋淬七次，水飞用，非。
《本经》主心腹咳逆邪气补不足，女子风寒在子宫，绝孕十年无子。
发明 紫石英入手足少阴、厥阴血分，上能镇心定惊悸，安魂魄，摄逆气，重以去怯也
。下能益肝填补下焦，散阴火，止消渴，温以暖血也。女子经阻色淡不孕者宜之。《本经》
治女子风寒在子宫，绝孕十年者，服之能孕，非特峻补，兼散浊阴留结之验也。若血热紫黑
者禁用，为其性温也。《千金》云，妇人欲求美色者，勿服紫石英，令人色黑，非温血之
谓乎。故妇人绝孕，由于阴虚火旺，不能摄精者禁用。
（白石英）味甘、性温，无毒。产于泰山。以具有六棱、晶莹洁白如水晶者为真品。林北海先生在《本草纲目必读》中，只收录了紫石英而未收录白石英，可知世间真正的白石英已很少见了。
《神农本草经》记载其治疗消渴病，阳痿不足，咳嗽气逆，胸膈间久积之寒邪，能益气并祛除风湿痹痛。
【发明】白石英入入手太阴肺经和足阳明胃经的气分，对于肺痈溃烂日久、痿痹不能起身者适宜。《神农本草经》主治消渴、阳痿不足等病，其功效专于温补肺气是毫无疑问的。但石类药物性质刚悍猛烈，不可长期服用。张仲景在《金匮要略》的风引汤中，只要求将药碎成米粒大小，是不希望其渣滓进入胃部。《千金方》中的五石等方剂，都经过水飞法处理后制成丸药，而五石丸专门以钟乳石为君药，配合紫石英、白石英、赤石脂、石膏，专门温补脏腑之气，其中石膏清胃热，以化解各种石药的刚悍之性，而且既然经过了水飞处理，就不必担心其渣滓滞留体内蕴结热气。
（紫石英）味甘、性温，无毒。产于泰山。以具有五棱、明净深紫色且块头大的为佳，浙江产的虽然块小也可以入药。经过火炼则会产生毒性，需研磨至极细，并经水飞法处理三次后使用。李时珍说：“用醋淬七次，再水飞使用”，这是不对的。
《神农本草经》记载其主治心腹部的咳嗽气逆及邪气，补益不足，女子因风寒侵袭子宫，导致十年不孕的情况。
【发明】紫石英入入手足少阴心和肾经、厥阴肝和心包经的血分，上行能镇心安神、定惊悸、安魂魄、摄纳逆气，是利用其重坠之性来去除怯懦之心；下行能益肝填补下焦，散除阴火，止住消渴，是利用其温热之性来温暖血液。女子因经脉阻滞、血色淡白而不孕者适宜使用。《神农本草经》治疗女子因风寒在子宫，导致十年不孕的情况，服用此药能够受孕，这不仅是峻猛补益的效果，也是兼有消散浊阴留结之邪的验证。如果血色紫黑属血热者禁用，因为其药性温热。《千金方》说，妇女想要追求美丽容貌的，不要服用紫石英，因为它会让人面色变黑，这不正是说明它能温煦血液吗？因此，妇人因阴虚火旺、不能摄精而导致的不孕，禁用紫石英。
(Bai Shiying / White Quartz) Sweet and warm, non-toxic. Originates from Mount Tai. The genuine variety is characterized by six edges, being crystal clear and white like rock crystal. Mr. Lin Beihai, in his *Bibei Bencao Gangmu* (Must-Read Compendium of Materia Medica), only recorded Zi Shiying but omitted Bai Shiying; it can be known that true Bai Shiying is rare in the world today.
The *Shennong Benjing* (Classic of Divine Husbandman's Materia Medica) states it treats Xiao Ke (Wasting-Thirst / Diabetes), Yin Wei Bu Zu (Insufficiency of Impotence), Ke Ni (Cough and Qi Reversal), Jiu Han in the Chest and Diaphragm (Chronic Cold in the Thoracic Region), and benefits Qi while dispelling Feng Shi Bi (Wind-Dampness Bi Syndrome).
[Invention] Bai Shiying enters the Qi aspect of the Hand-Taiyin Lung Meridian and Foot-Yangming Stomach Meridian. It is suitable for cases of Fei Yong (Lung Abscess) that have ulcerated for a long time, or Wei Bi (Flaccidity and Bi Syndrome) where one cannot rise. The *Shennong Benjing* primarily addresses Xiao Ke, Yin Wei Bu Zu, and other conditions; its efficacy is undoubtedly specialized in warming the Lungs. However, mineral drugs possess a fierce and aggressive nature and should not be taken for a long time. In Zhang Zhongjing’s *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet), the Feng Yin Tang (Wind-Driving Decoction) only requires crushing the mineral into rice-grain size, avoiding the dregs entering the stomach. In the *Qianjin Fang* (Prescriptions Worth a Thousand Gold), formulas such as Wu Shi Fang all undergo water-flying processing before being made into pills. Specifically, Wu Shi Wan (Five Minerals Pill) uses Zhong Ru (Stalactite) as the sovereign herb, combined with Zi Shiying, Bai Shiying, Chi Shi Zhi (Red Halloysite), and Shi Gao (Gypsum Fibrosum). This combination specifically warms the Zang organs' Qi. Shi Gao clears Stomach Heat to resolve the aggressive nature of the various minerals. Moreover, since they have undergone water-flying processing, there is no need to worry about dregs remaining in the middle jiao and generating heat.
(Zi Shiying / Purple Quartz) Sweet and warm, non-toxic. Originates from Mount Tai. The best quality has five edges, is bright and deep purple in color, and forms large chunks. Those produced in Zhejiang, although smaller in chunk size, can also be used medicinally. Heating over fire generates toxicity; it must be ground to an extremely fine powder and processed via water-flying three times. Li Shizhen stated: "Quench seven times in vinegar, then use after water-flying," which is incorrect.
The *Shennong Benjing* states it treats Xin Fu Ke Ni Xie Qi (Cough, Qi Reversal, and Pathogenic Factors in the Heart and Abdomen), tonifies insufficiency, and addresses cases in women where Feng Han (Wind-Cold) resides in the Zi Gong (Uterus), causing infertility for ten years.
[Invention] Zi Shiying enters the Blood aspect of the Hand-Shaoyin Heart Meridian, Foot-Shaoyin Kidney Meridian, Hand-Jueyin Pericardium Meridian, and Foot-Jueyin Liver Meridian. Ascending, it calms the Heart, settles palpitations, stabilizes the Hun and Po (Soul and Corporeal Soul), and controls rebellious Qi, utilizing its heavy nature to dispel timidity. Descending, it benefits the Liver, fills the Lower Jiao, dissipates Yin Fire, and stops Xiao Ke, utilizing its warm nature to warm the Blood. It is suitable for women with menstrual obstruction, pale blood color, and infertility. Regarding the *Shennong Benjing*'s treatment of women with Wind-Cold in the Uterus leading to ten years of infertility, taking this herb enables conception. This is not merely due to strong tonification but also verifies its ability to dissipate turbid Yin stagnation. If the blood is hot and dark purple, it is contraindicated because of its warm nature. The *Qianjin Fang* states that women seeking beauty should not take Zi Shiying, as it causes the complexion to darken; does this not refer to its property of warming the blood? Therefore, for women suffering from infertility due to Yin Deficiency with Hyperactive Fire, who are unable to secure essence, Zi Shiying is contraindicated.
