王又原曰。经曰。五脏六腑之精。皆上注于目。则目之能视者。气也。目之所以能视者。
精也肾惟藏精。故神水发于肾。心为离照。故神光发于心。光发阳而外。映有阴精以为守。
则不散而常明。水发阴而凝结。有阳气以为布。则洞悉而不穷。惟心肾有亏。致神水干涸。
神光短少。昏 内障诸症。所由作也。千金以磁石直入肾经。收散失之神。性能引铁。吸肺
金之气。归藏肾水。朱砂体阳而性阴。能纳浮游之火而安神明。水能鉴。火能烛。水火相济。

治疗神水（瞳孔及晶状体等眼内液体）逐渐散大，视物昏蒙如同在雾露中行走，渐渐看到空中有黑花飞舞，看物体变成两个影像，以及内障病表现为神水呈淡绿色或白色。又用于治疗耳鸣和耳聋。柯韵伯说：此方治疗聋、癫、狂、痫等症效果如神。
磁砂丸最能调和阴阳。神曲能使谷气（脾胃运化功能）昌盛。（配方为：磁石二两，朱砂一两，生神曲三两，再用一两神曲用水和成饼煮熟，浮起后加入前两种药中，用炼蜜制成丸剂。）此方能同时治疗内障、黑花飞舞和耳聋。若用于治疗癫痫，则有奇特的长处。
王又原说：《内经》记载：五脏六腑的精气，都上注于眼睛，所以眼睛能看见东西，依靠的是气；眼睛之所以能看见，依靠的是精。肾专门贮藏精气，所以神水发源于肾。心如同离卦之光照耀，所以神光发源于心。神光发于阳而向外发散，映照并依靠阴精来固守，则不散失而常明亮。神水发于阴而凝结，依靠阳气来布散，则洞察透彻而没有穷尽。只有当心肾亏损时，导致神水干涸，神光短少，昏花、内障等各种症状，由此产生。千金方用磁石直接入肾经，收敛散失的神气，其性能吸引铁，吸收肺金之气，归藏于肾水。朱砂体质属阳而性质属阴，能收纳浮游之火而安定神明。水能像镜子一样照物，火能像蜡烛一样照明，水火相互济助，那么光华就不会四射外泄。然而眼睛接受脏腑的精气，精气来源于五谷，神曲能消化五谷，那么精气就容易生成。大概神水散大，缓慢则不能收回，依赖具有镇坠作用的药物，迅速收敛并吸引它，所以这是急救的药剂。它治疗耳鸣耳聋等症状，也是利用镇坠的功能，制约虚阳的上奔。柯韵伯说：此丸是治疗癫痫的圣剂。大概狂痴是心、脾、肾三脏的疾病。心藏神，脾藏意与智，肾藏精与志。心是神明的主宰。《内经》说：主宰不明，则十二官（指全身脏腑器官）都会危险，使气道闭塞而不通，形体就会大大受损，说的就是这种情况。然而主宰为什么不明呢？心法象离卦而属于火，真水藏在其中。如果天一之真水不足，地二之虚火就要妄行，所谓天气被遮蔽，地气冒犯光明，日月不明，邪气侵害空窍，所以眼睛多出现幻视，从而产生这种奇疾。不用金石类的重镇药物来镇压，狂症必定不止。朱砂禀受南方的赤色，入通于心，能降无根之火而安定神明。磁石禀受北方的黑色，入通于肾，吸收肺金之气以生精，坠炎土之火以定志。这两味石头类药物体重而主降，性寒而滋阴，志同道合，奏效可以立刻期待。神曲推陈出新，上交心神，下达肾志，以产生意智。而且食物进入体内滋养阴分，长养阳气，夺取食物的来源病就好了，这是《内经》治疗狂症的方法。食物消化了，意智就清明而精神就正常，这就是使用神曲的宗旨吧。用炼蜜调和做成丸剂，又是用甘味来缓急啊。
Indicated for the gradual dilation of Shen Shui (aqueous humor and related intraocular fluids), visual obscuration as if walking in fog or dew, gradually seeing black spots floating in the air, diplopia (seeing objects as double images), and internal cataracts presenting with Shen Shui appearing pale green or white. Also indicated for tinnitus and deafness. Ke Yunbo stated: This formula is miraculous in treating deafness, epilepsy, mania, and convulsions.
Ci Sha Wan (Magnetite and Cinnabar Pill) best harmonizes Yin and Yang. Shen Qu (Medicated Leaven) can promote the flourishing of Gu Qi (Grain Qi/Spleen-Stomach digestive function). [Formula composition: Ci Shi (Magnetitum, Magnetite) 2 liang, Zhu Sha (Cinnabaris, Cinnabar) 1 liang, Sheng Shen Qu (Levisticum Officinale Medicinal Leaven) 3 liang raw; additionally, 1 liang of Shen Qu is mixed with water to form a cake, boiled until it floats, then added to the previous medicines, and formed into pills with refined honey.] This formula simultaneously treats internal cataracts, floating black spots, and deafness. If used to treat epilepsy, it has extraordinary efficacy.
Wang Youyuan stated: The *Classic of Internal Medicine* records: The essence of the five zang organs and six fu organs all ascend to nourish the eyes. Thus, the ability of the eyes to see relies on Qi; the reason the eyes can see relies on Essence. The Kidney exclusively stores Essence, therefore Shen Shui originates from the Kidney. The Heart is like the light of the Li trigram shining forth, therefore Shen Guang (Spiritual Light/Vision) originates from the Heart. Shen Guang emanates from Yang and projects outward, reflecting and relying on Yin Essence to guard it, thus it does not scatter and remains bright. Shen Shui emanates from Yin and condenses, relying on Yang Qi to distribute it, thus it sees clearly without limit. Only when the Heart and Kidney are deficient does Shen Shui become dry and Shen Guang become scanty, causing symptoms such as blurred vision and internal cataracts. The *Qian Jin Fang* uses Ci Shi (Magnetitum, Magnetite) to directly enter the Kidney meridian, gathering scattered Shen (Spirit); its nature attracts iron and absorbs the Qi of Lung Metal, returning it to store in Kidney Water. Zhu Sha (Cinnabaris, Cinnabar) has a physical nature of Yang but an energetic nature of Yin; it can subdue floating fire and calm the Shen Ming (Spiritual Consciousness). Water acts as a mirror, Fire acts as a candle; when Water and Fire mutually support each other, the brilliance will not scatter outward. However, the eyes receive the essence of the zang-fu organs, which is derived from grains. Shen Qu (Medicated Leaven) can digest the five grains, thereby facilitating the formation of essence. Generally, when Shen Shui dilates, if left slowly it cannot be retracted; it relies on substances with sedative and descending properties to rapidly gather and attract it back, hence this is an emergency rescue formula. Its treatment of tinnitus and deafness also utilizes these sedative and descending functions to restrain the upward rushing of Deficient Yang. Ke Yunbo stated: This pill is a sacred remedy for epilepsy. Mania and dementia are diseases of the Heart, Spleen, and Kidney. The Heart stores Shen (Spirit), the Spleen stores Yi (Intellect/Thought) and Zhi (Wisdom), and the Kidney stores Jing (Essence) and Zhi (Will). The Heart is the master of Shen Ming (Spiritual Consciousness). The *Classic* says: If the Master is unclear, the twelve officials (organs) are endangered, causing the pathways to become blocked and the body to suffer greatly; this refers to that situation. But why is the Master unclear? The Heart corresponds to the Li trigram and belongs to Fire, with True Water hidden within. If the True Water of Tian Yi (Heavenly Number One) is insufficient, the empty fire of Di Er (Earthly Number Two) will act recklessly. This means the Heavenly Qi is obstructed, and the Earthly Qi overpowers the brightness, like the sun and moon losing their clarity, allowing pathogenic factors to harm the orifices, resulting in visual hallucinations and producing such strange diseases. Without heavy mineral and stone sedatives to suppress it, mania will certainly not cease. Zhu Sha (Cinnabaris, Cinnabar) inherits the red color of the South, connects internally with the Heart, and can descend rootless fire to calm the Shen Ming. Ci Shi (Magnetitum, Magnetite) inherits the black color of the North, connects internally with the Kidney, absorbs Lung Metal Qi to generate essence, and descends the fire of Inflaming Earth to stabilize the Will. These two mineral substances are heavy and primarily descending, cold in nature and nourishing Yin; they share similar goals and actions, so their efficacy can be expected immediately. Shen Qu (Medicated Leaven) eliminates the old and generates the new, communicates upward with Heart Shen and downward with Kidney Zhi, thereby generating Yi and Zhi. Moreover, food enters to nourish Yin and generates Yang; removing the source of food resolves the condition—this is the method for treating mania in the *Inner Canon*. When food is digested, Yi and Zhi become clear and Spirit is regulated; this is the purpose of using Shen Qu. Forming pills with refined honey further employs the sweet flavor to moderate urgency.
