【气味】味咸，性微温，无毒。
【主治】治疗妇女崩中漏下（非经期大量出血或淋漓不尽），破除子宫内的瘀血，消散症瘕结气（腹内结块及气机郁滞），缓解因寒热错杂导致的腹痛及不孕症，改善阳痿不起，以及补益身体亏虚之处。
（阳起石是云母的根。产于齐州的齐山，以及庐山、泰山、云山、沂州、琅琊等地的山谷中。如今只有齐州开采，其他地方已不再知晓其存在。齐州仅有一座土山，石头出产于山中，当地人称之为阳起山。这座山常年有暖气蒸腾，即使隆冬大雪覆盖整个地区，唯独此山没有积雪。这是因为石头的热气熏蒸所致。山上只有一个矿穴，官府经常封闭禁闭，每年冬天初时，州里征调民夫，派人监督开采以进贡朝廷，岁月长久，矿穴越来越深，从其他石头中凿取它非常困难。以白色明亮晶莹、纹理如云头雨脚般轻松、形状像野狼牙的为上品。黄色的也受重视，上面还带有云母的，是绝品。挑选出来供朝廷使用的，剩下的，当地人才出售，否则无法得到。将其置于雪中瞬间消失痕迹的是真品；画在纸上在阳光下扬起能飞起的，也是真正佳品。）
阳起石，是这座山的石头，是阳气生发之处，所以大雪遍境，而山上无积雪。作为有形的石头，聚集了阳气，所以置于雪中，瞬间消失痕迹，放在阳光下，自然能飞起。主治崩中漏下，崩漏属于阴证，现在随阳气而上升。破除子宫内的瘀血，以及症瘕结气，是因为阳气增长则阴消，阳气透发，则症结破碎消散。妇人月经不能按时来潮，则出现寒热腹痛且不孕。阳起石贞固下元开启新元，阴中有阳，阴阳调和则寒热消除，月经调畅则生育繁衍。男子精气虚弱，则阳痿不起。阳起石辅助阴中之阳，所以治疗阳痿不起，并补肾精的不足。
[Flavor and Nature] Salty, slightly warm, non-toxic.
[Indications] Treats metrorrhagia and metrostaxis (heavy bleeding or prolonged spotting between periods), breaks down blood stasis in the uterus, dissipates masses and qi stagnation (abdominal lumps and qi constraint), alleviates abdominal pain and infertility caused by alternating cold and heat, treats impotence with inability to erect, and tonifies deficiencies.
(Yangqishi [Calcis Silicatis] is the root of Muscovite Mica. It originates from Qishan Mountain in Qizhou, as well as valleys in Lushan, Mount Tai, Yunshan, Yizhou, and Langya. Currently, only Qizhou mines it; its existence is no longer recognized elsewhere. Qizhou has only one earthen mountain where the stone is found, locally called Yangqi Mountain. This mountain constantly emits warmth; even in mid-winter when heavy snow covers the entire region, this mountain alone remains free of accumulated snow. This is due to the steaming effect of the stone's qi. There is only one mine shaft on the mountain, which was often sealed and forbidden by the government. Every early winter, the prefecture conscripted laborers and sent supervisors to extract it for tribute. Over the years, the shaft became deeper, making it very difficult to quarry it from other stones. The best quality is white, bright, and crystal clear, with textures resembling cloud heads and rain feet that are light and airy, shaped like wild wolf teeth. Yellow ones are also valued; those still retaining muscovite mica on them are considered supreme grade. After selecting the best for tribute, the remainder was sold by locals; otherwise, it could not be obtained. The authentic variety disappears instantly when placed in snow; if drawn on paper and shaken under sunlight, causing it to fly up, it is truly excellent.)
Yangqishi is the stone of this mountain, a place where yang qi arises; hence, while snow covers the surroundings, the mountain remains snow-free. As a tangible stone, it concentrates yang qi; thus, when placed in snow, it vanishes instantly, and under sunlight, it naturally lifts and flies. Its indication for metrorrhagia and metrostaxis addresses these conditions, which belong to yin pathology, now ascending along with yang qi. By breaking down uterine blood stasis and dissipating masses and qi stagnation, it operates through the principle that as yang grows, yin diminishes; when yang qi penetrates and emerges, the pathological knots break and disperse. When women’s menstruation does not arrive on time, it results in alternating cold and heat, abdominal pain, and infertility. Yangqishi stabilizes the lower origin and initiates new beginnings; containing yang within yin, it harmonizes yin and yang, eliminating alternating cold and heat, regulating menstruation, and promoting fertility. In men, deficiency of essence leads to impotence with inability to erect. Yangqishi assists the yang within yin; therefore, it treats impotence and tonifies the insufficiency of kidney essence.
