（本经上品）
春秋二分，阴阳离也。
【气味】辛平，无毒。
【主治】主五脏邪气，女子阴中寒热痛，症瘕血闭绝子。久服轻身，和颜色。
【核】曰∶出常山山谷，关陕、沂、兖亦有之。丛生石上，春分宿根再发，高三五寸，
细叶似侧柏，屈藏如鸡足根紫赤多须。六七月采取阴干。修治，以盐水煮半日，再以井水煮
半日
【 】曰∶叶形似柏，屈曲拳挛，因名卷柏。一名豹足、求股，亦取象形。一名万岁、
长生不死草，言根栖岩石，能耐岁寒。一名交时，言春分始发，时值阴离于阳，能与阳相交
合。故主五脏至阴之地，为邪所薄，及女子阴中寒热，症瘕，血闭绝子。此正阴不与阳，功
能使阴气起亟，阳气前通，交相匹配。更能使阳气外溢，故和色，轻身，所谓阳在外，阴之
使也
（本经上品）
【气味】甘温，无毒。
【主治】主心腹咳逆邪气，补不足，女子风寒在子宫，绝孕十年无子。久服温中，轻身
延年
【核】曰∶出太山山谷，岭表录异云∶泷州山中多紫石英，其色淡紫，其质莹彻，随其
小大，皆具五棱，两头如箭镞。比之白石英，其力倍矣。太平御览云∶自大岘至太山，皆出
紫石英。太山者，甚环玮。平氏阳山县者，色深特好。乌程县北垄山者，甚光明，但小而
黑。东莞县爆山者，旧以贡献。江夏矾山亦有。永嘉固陶村小山者，芒角甚佳，但小薄耳。
必以五棱如削，紫色达头，如樗蒲者乃良。修治，火 醋淬，凡七遍，研末，水飞三四次，
晒干入药。长石为之使。畏扁青、附子。恶 甲、黄连、麦句姜；得茯苓、人参，疗心中结
气。得天
先人云∶温润如玉，则心光可通，饵服者无妄躁，获益当无量矣。
【 】曰∶赤黑相间曰紫，坎离交会之色也。石乃山骨，英乃石华。艮山为体，震动为
用，故主体用不足，致邪入心腹，作咳作逆者。正离失虚中，坎失刚中耳。若风寒在子宫，
绝孕无子，十年弗克攻者，藉坎离交会，则体用双彰，十年乃字矣。久服温中，轻身，互坎
填离之验也。

(Shennong Bencao Jing, Upper Grade)
The spring and autumn equinoxes are times when Yin and Yang separate.
[Flavor and Nature] Acrid, neutral in nature, non-toxic.
[Indications] Primarily treats pathogenic factors in the five Zang organs; cold-heat pain in the female genitalia; zheng zha (abdominal masses); blood obstruction leading to sterility. Long-term consumption lightens the body and harmonizes the complexion.
[Verification] It is stated: Grows in the valleys of Changshan; also found in Guan-Shan, Yizhou, and Yanzhou. It grows in clusters on rocks. At the Spring Equinox, the perennial roots sprout again, growing three to five cun high. The leaves are fine like those of Platycladus orientalis (Cypress), curled and hidden like chicken feet roots, purple-red with many rootlets. Harvested in the sixth and seventh lunar months and dried in the shade. Processing: Boil in salt water for half a day, then boil in well water for another half day.
[Commentary] It is said: The leaf shape resembles cypress, curled and contracted, hence named Juanbai (Curled Cypress). Also known as Baozu (Leopard Foot) or Qiugu (Seeking Thigh), names derived from its morphology. Also known as Wansui (Ten Thousand Years) or Changsheng Busi Cao (Grass of Immortality), referring to its roots dwelling on rocks, enduring the cold of the year. Also known as Jiaoshi (Time of Intersection), indicating it sprouts at the Spring Equinox, when Yin separates from Yang, allowing it to interact and merge with Yang. Thus, it treats pathogenic invasion in the most Yin locations of the five Zang organs, as well as cold-heat in the female genitalia, zheng zha, and sterility due to blood obstruction. This addresses the condition where Yin does not interact with Yang; its efficacy causes Yin Qi to rise rapidly and Yang Qi to penetrate forward, achieving mutual matching. It further allows Yang Qi to overflow outward, thereby harmonizing the complexion and lightening the body, illustrating the principle that "Yang resides outside, serving as the agent of Yin."
(Shennong Bencao Jing, Upper Grade)
[Flavor and Nature] Sweet, warm in nature, non-toxic.
[Indications] Primarily treats rebellious Qi and pathogenic factors in the heart and abdomen; tonifies deficiency; wind-cold in the uterus causing ten years of infertility. Long-term consumption warms the Middle Jiao, lightens the body, and prolongs life.
[Verification] It is stated: Produced in the valleys of Mount Tai. Lingbiao Luyi records: In Longzhou mountains, Ziyan Shi (Purple Quartz) is abundant; its color is pale purple, texture crystal clear; regardless of size, it possesses five edges, with both ends resembling arrowheads. Compared to Baiyan Shi (White Quartz), its therapeutic power is doubled. Taiping Yulan records: From Daxian Mountain to Mount Tai, Ziyan Shi is produced. The stones of Mount Tai are exceptionally rare. Those from Yangshan County in Pingshi have a deep color and are excellent. Those from Beilong Mountain in Wucheng County are very bright but small and black. Those from Baoshan in Dongguan County were formerly offered as tribute. Fan Mountain in Jiangxia also produces it. Small hills in Gutao Village, Yongjia produce stones with good edges but are small and thin. The best quality must have five edges as if cut, purple color reaching the tip, resembling dice (chupu). Processing: Calcine over fire and quench in vinegar, repeating seven times. Grind into powder, wash with water (water levigation) three to four times, dry and use in medicine. Changshi (Longstone) acts as its guide drug. It is incompatible with Bianqing (Blue Mineral) and Fuzi (Prepared Aconite Root). It is repelled by Guijia (Tortoise Shell), Huanglian (Coptis Rhizome), and Maijujiang (Polygonatum Odoratum? Note: Text says 麦句姜, likely a specific local name or typo for a herb, kept as is); combined with Fuling (Poria) and Renshen (Ginseng Root), it treats stagnation of Qi in the heart. Tian... [Text missing here].
My ancestor said: Warm and moist like jade, allowing the light of the heart to communicate; those who ingest it will not suffer from reckless agitation; the benefits gained are immeasurable.
[Commentary] Purple is described as intermixed red and black, the color of Kan-Li intersection. Stone is the bone of the mountain; Ying (Essence) is the flower of the stone. Gen Mountain forms the substance (Ti), while Zhen Thunder provides the function (Yong). Therefore, it treats insufficiency of substance and function, which allows pathogens to enter the heart and abdomen, causing cough and rebellious Qi. This is precisely because the Li trigram loses its empty center, and the Kan trigram loses its solid center. If wind-cold is in the uterus, causing ten years of infertility that cannot be cured, relying on the intersection of Kan and Li, both substance and function are manifested, and pregnancy can be achieved after ten years. Long-term consumption warms the middle and lightens the body, verifying the efficacy of filling Kan to support Li.
(The empty center and solid center represent the profound mutual root of Yin and Yang.)
