云母是阳起石的根基。它产于泰山、齐山的山谷以及琅琊地区。如今只出产于齐州（即济南府历城）。那里的山常年温暖，冬天不积雪。每年初冬，州官监督开采。由于长期挖掘，洞穴很深。需要凿开其他石头才能获取，非常困难。以白色明亮晶莹、形状像云头雨脚、质地轻松如同野狼牙的为上品。黄色的也属贵重，上面还带有云母的，称为绝品。（引自《名医别录》及苏颂）
阳起石属于阳性的石头，产自齐州拣金山的最为优良。其尖端像箭簇的效力强，像狗牙的效力微弱。放在雪中会瞬间消失踪迹，写在纸上能飘然飞起的才是真品。（引自《庚辛玉册》）
气味咸，性温。是作用于右肾和命门气分的药物。桑螵蛸作为它的引导药。它厌恶泽泻、菌桂、雷丸、石葵、蛇蜕。畏惧菟丝子。忌食羊血。它能补益命门的不足，治疗阳痿不起，以及腰痛、膝冷、湿痹。对于妇人子宫久冷、冷症寒瘕、月经不调、结气寒热、腹痛不孕，以及男女下部虚冷、肾气乏绝、子宫久寒者，均可使用。然而矿物药无论冷热都有毒性，也应当斟酌使用。（引自寇宗奭）况且它不是可以长期服用的药物。（引自李时珍）
喉痹是相火急速发作的疾病，相火即龙火。适宜用“火”来驱逐它。有一人患缠喉风，表里都肿胀，药物无法咽下。用凉药灌鼻，导致腹泻十余次。外用阳起石和伏龙肝等量研成细粉，用新汲水调和，每天涂抹一百遍，三天后热退肿消。这也是顺从病势治疗的道理。（引自张子和）
阳气在外，是阴气的使役；阴气在内，是阳气的守持。阴气贮藏精气并迅速响应需求，阳气护卫体表并保持固密。阳起石能兼顾阴阳两方面。（引自苏辙）
它禀受纯阳之气而生。《神农本草经》说它气微温。但观察出产这种石头的山，大雪都不凝结，那么它的温热之气，应该不仅仅是很微弱了。咸味入右肾，补助阳气，是清除下焦积寒、宿血、留滞的圣药。（引自陈士铎）对于阳痿不起、精寒无嗣者，配合温补药物服用，能使性功能强健，总治男子九种丑疾，使人能够生育。
【论述】
凡是禀受阳气旺盛的事物，没有不上行的。这座山的气独钟于此而凝结成这种石头。（类似温泉的情况不多见）使用者只是取它的阳气，所以以质地轻松、像野狼牙、放在纸上就能飞起的为佳。阳火出于地中，适宜补益命门不足，起阴痿，暖子宫，是男女下焦疾病的圣药。各种证候的治疗，都是取其上升的阳气，通过动而不止的气化作用，以对待之。只是苏颂时代就已经说难以获得，至今使用假药的，不如不用更好。阴虚火旺者忌用。阳痿属于失志（火气闭密不得发越所致），崩漏由于火盛者，都不得服用。（引自陈士铎）
【炮制】
不入汤剂煎煮。用火煅透至红，研成极细如面粉状，用水飞法处理，晒干后使用。
Muscovite is the root of Yangqishi (Actinolite). It grows in the valleys of Mount Tai, Qi Mountain, and Langya. Currently, it is only produced in Qizhou (i.e., Licheng District, Jinan Prefecture). The mountains there are constantly warm, with no snow accumulation in winter. Every early winter, local officials supervise its extraction. Due to long-term mining, the caves become deep. It requires chiseling through other rocks to obtain it, which is very difficult. Those that are white, bright, and crystal clear, with shapes resembling cloud heads and rain feet, and a light texture like wild wolf teeth, are considered superior. Yellow ones are also valuable; those still bearing muscovite on them are called the finest grade. (Cited from *Bielu* and Su Song)
Yangqishi belongs to yang stones. Those mined from Jianjin Mountain in Qizhou are the best. Those with tips resembling arrowheads have strong potency, while those resembling dog teeth have weak potency. If placed in snow and it instantly leaves no trace, or if written on paper and floats away lightly, it is genuine. (Cited from *Gengxin Yuce*)
The flavor is salty, and the nature is warm. It is a herb acting on the qi aspect of the right kidney and Mingmen (Gate of Vitality). Sangpiaoxiao (Mantis Egg Case) serves as its guiding herb. It is incompatible with Zexie (Alisma Rhizome), Jungui (Cinnamomum Cassia Bark), Leiwan (Fritillaria Thunbergii Bulb), Shi Kui (Suaeda Glauca), and Shetui (Snake Skin). It fears Tusizi (Cuscuta Seed) and should avoid mutton blood. It tonifies the deficiency of Mingmen, treats impotence (Yinwei) with inability to erect, as well as lower back pain, cold knees, and bi-syndrome due to dampness. For women with long-standing cold uterus, cold masses (Hanxia), irregular menstruation, stagnant qi with alternating hot and cold sensations, abdominal pain leading to infertility, and for both men and women with deficiency-cold in the lower jiao, exhaustion of kidney qi, and long-standing cold of the zi zang (uterus), it can be used. However, mineral herbs, whether cold or warm, possess toxicity, and their use should be carefully considered. (Cited from Kou Zongshi) Moreover, it is not a substance for long-term consumption. (Cited from Li Shizhen)
Houbi (Sore throat/Pharyngitis) is a disease caused by the rapid flare-up of Xianghuo (Ministerial Fire), which is also Longhuo (Dragon Fire). It is appropriate to expel it using "fire" methods. A patient suffered from Chantoufeng (Peritonsillar Abscess/Tight Throat Wind), with swelling inside and out, making oral medication impossible. Cold medicines were instilled into the nose, causing more than ten episodes of diarrhea. Externally, Yangqishi (Actinolite) and Fulonggan (Settled Dragon Liver/Kiln Earth) were mixed in equal parts, ground into fine powder, and applied daily one hundred times with fresh water drawn from a well. After three days, the heat subsided and swelling disappeared. This is also a method of treating according to the disease's nature (Congzhi). (Cited from Zhang Zihe)
Yang (Qi) outside is the servant of Yin; Yin inside is the guardian of Yang. Yin stores essence and responds rapidly; Yang protects the exterior and maintains solidity. Yangqishi benefits both aspects. (Cited from Su Zhe)
It is born from pure yang qi. *Benjing* (*Shennong Bencao Jing*) states its qi is slightly warm. However, observing the mountains where this stone is found, where even heavy snow does not freeze, its warming qi must be more than just slightly warm. Salty and warm, it enters the right kidney, supplements yang qi, and is a supreme herb for eliminating accumulated cold, old blood stasis, and stagnation in the lower jiao. (Cited from Chen Shidun) For cases of impotence with inability to erect and cold sperm leading to infertility, taken with warming and tonifying herbs, it can strengthen sexual function and treat the nine deficiencies of men, enabling procreation.
[Discussion]
All things that endow abundant yang qi tend to ascend. The qi of this mountain is uniquely concentrated here, condensing into this stone. (Similar phenomena, such as hot springs, are rare.) Users only seek its yang qi; therefore, those that are light in texture, resemble wild wolf teeth, and float when placed on paper are preferred. Yang fire originates from within the earth, making it suitable for tonifying Mingmen deficiency, restoring erection, warming the uterus, and serving as a supreme herb for diseases of the lower jiao in both men and women. Various treatments utilize its ascending yang, employing dynamic qi transformation to address the condition. However, since Su Song already noted its scarcity, and today fake versions are common, it is better not to use it at all. It is contraindicated in cases of yin deficiency with fire hyperactivity. Impotence due to loss of willpower (where fire qi is closed and cannot vent) and metrorrhagia due to excessive fire should not take this herb. (Cited from Chen Shidun)
[Processing]
Not used in decoctions. Calcined over fire until red, ground extremely finely like flour, processed by water levigation (shui fei), and dried in the sun before use.
