睛散，睛散则岐，故见两物。此言尚非定论。治法必须大补其肝气，使肝足以应脑，
则肝气足而脑气亦足也。方用助肝益脑汤∶
白芍（二两） 当归（一两） 人参（三钱） 郁李仁（二钱） 柴胡（五分） 天花粉（二钱）
细辛（五分） 川芎（三钱） 甘菊花（五钱） 薄荷（八分） 生地（五钱） 天门冬（三钱） 甘草（一钱）
白芷（三分） 水煎服。
一剂而视物为一矣，二剂全愈。
此方全是益肝之药，非益脑之品也。不知补脑必须添精，而添精必须滋肾。然
而滋肾以补脑，而肝之气不能遽补，不若直补其肝，而佐之祛邪之药为当。盖脑气
不足，而邪得以居之，不祛邪而单补其精于脑气，正无益也，治肝正所以益脑也。
此症亦可用补瞳神丹∶
当归 白芍（各一两） 郁李仁 黑荆芥 丹皮（各三钱） 麦冬 川芎 葳蕤（各五钱）
细辛（五分） 水煎服。二剂愈。
人有病目之后，眼前常见禽鸟昆虫之飞走，捉之则无，人以为怪，而不知非怪
也，乃肝胆血虚，有痰而闭结之也。夫肝胆属木，木中无血以润之，则木气过燥矣。
内燥必取给于外水，然而肝胆喜内水之资，而不喜外水之养，于是外水不变血而变
痰。血资肝胆则有益，痰侵肝胆则有损，且血能入于肝胆之中，痰难入于肝胆之内。
痰既在外，反壅塞肝胆之窍，而气不能展矣。见禽鸟昆虫之飞走者，皆痰之作祟也。
治法益肝胆之血，而兼消其外壅之痰。方用四物汤加味治之。
熟地（三钱） 白芍（五钱） 当归（一两） 川芎（二钱） 酸枣仁（五钱） 青葙子（三钱）
茯神（三钱） 陈皮（一钱） 甘草（一钱） 半夏（三钱） 白术（二钱）水煎服。四剂目无所见矣。
此方用四物汤以滋肝胆，用茯苓、半夏、白术以分消其湿痰。加入枣仁、青葙
者，以青葙走目中之系，枣仁去心内之迷，心气清而痰易出，目系明而邪自散也。
然但用二味，而不合前药同用，正未能出奇制胜耳。
此症用向荣汤亦妙。
当归 白芍 生地（各一两） 麦冬（五钱） 白芥子 茯苓（各三钱） 贝母（一钱） 柴胡（五分）
水煎服。十剂全愈。

夫肾中之邪，不过寒湿之气，用辛燥温热之剂，自易祛邪，况佐之夺门之将，辅之引路

人有月经不通，三月忽然眼目红肿，疼痛如刺，人以为血虚而不能养目也，谁
知是血壅而目痛乎。夫经水不通，似乎血枯之症，然而血过于盛，则肝气反闭塞而

痛矣。此等之痛，肝脉必大而有力，或弦而滑，必非细涩微缓无力之状也。治法不
可补血以助热，宜通经以泻肝。方用开壅汤∶
红花（三钱） 当归尾（三钱） 牛膝（二钱） 桃仁（十四个） 柴胡（二钱） 丹皮（三钱）
大黄（一钱） 香附（一钱） 郁金（三钱） 天花粉（二钱） 玄胡索（一钱） 水煎服。一剂而经通，再
剂而目愈。
此方全不治目，但去通经，经通而热散，热散而目安也。
此症可用泻壅丹∶
当归（一两） 红花（五钱） 大黄（二钱） 生地（五钱） 荆芥（三钱） 桃仁（十粒） 丹皮（三钱）
炒栀子（二钱） 水煎服。一剂而血通，二剂而目之肿全消，不必三剂也。
眼睛视物散乱，视物散乱则出现重影，所以看到两个物体。这种说法尚不是定论。治疗方法必须大补肝气，使肝脏功能足以响应脑部需求，那么肝气充足而脑气也随之充足。方剂用助肝益脑汤：白芍（二两） 当归（一两） 人参（三钱） 郁李仁（二钱） 柴胡（五分） 天花粉（二钱） 细辛（五分） 川芎（三钱） 甘菊花（五钱） 薄荷（八分） 生地（五钱） 天门冬（三钱） 甘草（一钱） 白芷（三分），水煎服。服用一剂后视物便合为一个，两剂后完全痊愈。
这个方子全是补益肝脏的药物，并非补益脑部的药物。不知道补脑必须添精，而添精必须滋补肾阴。然而通过滋肾来补脑，肝的气血不能迅速补充，不如直接补肝，并辅以祛邪的药物更为妥当。因为脑气不足，邪气得以停留，如果不祛除邪气而单纯在脑中补精，确实没有益处，治疗肝脏正是为了补益脑部。此症也可以用补瞳神丹：当归、白芍（各一两） 郁李仁、黑荆芥、丹皮（各三钱） 麦冬、川芎、葳蕤（各五钱） 细辛（五分），水煎服。两剂痊愈。
有人患眼病之后，眼前经常看见禽鸟昆虫飞走，去捕捉却什么都没有，人们认为很奇怪，却不知道这并不奇怪，乃是肝胆血虚，有痰浊闭结所致。肝胆属木，木中如果没有血液滋润，那么木气就会过于干燥。内部的燥热必然向外索取水分，然而肝胆喜欢内部水分的资助，而不喜欢外部水分的滋养，于是外部的水分不能转化为血液而转化为痰。血液资助肝胆则有益处，痰浊侵犯肝胆则有损害，而且血液能进入肝胆之中，痰浊难以进入肝胆之内。痰浊既然在外部，反而壅塞了肝胆的窍道，导致气机不能舒展。看见禽鸟昆虫飞走的景象，都是痰浊作祟的结果。治疗方法是补益肝胆之血，同时消除外部壅滞的痰浊。方剂用四物汤加味治疗。熟地（三钱） 白芍（五钱） 当归（一两） 川芎（二钱） 酸枣仁（五钱） 青葙子（三钱） 茯神（三钱） 陈皮（一钱） 甘草（一钱） 半夏（三钱） 白术（二钱），水煎服。四剂后眼中不再见到幻象。
这个方子用四物汤来滋补肝胆，用茯苓、半夏、白术来分消湿痰。加入酸枣仁、青葙子的原因，是因为青葙子能作用于目系，酸枣仁能去除心内的迷乱，心气清明则痰浊容易排出，目系明亮则邪气自然消散。然而如果只用这两味药，而不与前药同用，正不能出奇制胜。
此症用向荣汤也很奇妙。当归、白芍、生地（各一两） 麦冬（五钱） 白芥子、茯苓（各三钱） 贝母（一钱） 柴胡（五分），水煎服。十剂完全痊愈。
有人在目痛之后，双眼的眼白全部变为黑色，不痛不痒，仍能正常视物，毛发直立如铁条，神情痴呆如醉酒，不说话不交流，人们认为是血逆的病症，谁知道这是肾邪侵犯心脏呢？心属火，肾属水，这两经似乎相克，然而心火非肾水不能相互滋养，肾水不上交于心，则心必有烦躁的忧虑。但肾水仅可资助于心，而不可过度欺侮心。肾气侵犯心，本想救助心的干枯，但如果肾中有邪水，也携带它来资助心，那么心就会受伤。心受到肾邪的侵犯，本是死症却不死，只是眼睛呈现黑色，这是因为肾来救心，而非犯心。心畏惧肾邪，又不敢明显彰显肾的过错，眼白变黑，红白难分，毛发直立竖起，这不是愤怒到极点的表现吗？神情痴呆如醉酒，不说话不交流，这不是被挟制太甚、无可奈何的景象吗？治疗方法应当斩关直入，急救心君于垂危，祛除荡涤肾邪，拨乱反正才是得当的。方剂用转治汤：茯苓（五钱） 人参（五钱） 附子（二钱） 五灵脂末（二钱） 石菖蒲（一钱） 白芥子（三钱） 白术（五钱） 良姜（一钱），水煎服。一剂后痴醉状态清醒，两剂后毛发变软，三剂后黑色消退，四剂完全痊愈。
肾中的邪气，不过是寒湿之气，使用辛温燥热的药剂，自然容易祛除邪气，何况辅佐以夺门之将（强力药物），引导以引路之人（引经药），难道不能在顷刻间恢复健康，平定混乱吗？
此症用利水益心丹也很好。茯苓、人参、薏苡仁、巴戟天（各五钱） 白芥子、肉桂（各三钱） 白术（一两），水煎服。四剂完全痊愈。
有人月经不通，三个月后突然眼目红肿，疼痛如针刺，人们认为是血虚而不能滋养眼睛，谁知道这是血壅滞而导致目痛呢？月经不通，似乎是血枯的病症，然而血液过于盛实，则肝气反而闭塞而不通。月经既然不通，则热邪无处宣泄，不向下运行而转而壅滞于上部，而肝的窍道开于眼睛，于是热气走窜至肝而引发目痛。这类疼痛，肝脉必定大而有力，或弦滑，绝不是细涩微缓无力的脉象。治疗方法不可补血以助长热邪，宜通经以泻肝火。方剂用开壅汤：红花（三钱） 当归尾（三钱） 牛膝（二钱） 桃仁（十四个） 柴胡（二钱） 丹皮（三钱） 大黄（一钱） 香附（一钱） 郁金（三钱） 天花粉（二钱） 玄胡索（一钱），水煎服。一剂后月经通畅，再剂后眼睛痊愈。
这个方子完全不治疗眼睛，只注重通经，经络通畅则热邪消散，热邪消散则眼睛安宁。
此症可用泻壅丹：当归（一两） 红花（五钱） 大黄（二钱） 生地（五钱） 荆芥（三钱） 桃仁（十粒） 丹皮（三钱） 炒栀子（二钱），水煎服。一剂后血液通畅，二剂后眼睛肿胀全消，不必等到第三剂。
The vision scatters; when vision scatters, diplopia (double vision) occurs, hence the perception of two objects. This statement is not yet a definitive conclusion. The treatment method must greatly tonify Liver Qi (Liver energy), enabling the Liver to adequately respond to the Brain. When Liver Qi is sufficient, Brain Qi will also be sufficient. The formula used is Zhugan Yinao Tang (Assist Liver and Benefit Brain Decoction): Baishao (Radix Paeoniae Alba, 2 liang), Danggui (Radix Angelicae Sinensis, 1 liang), Renshen (Radix Ginseng, 3 qian), Yuliren (Semen Pruni Armeniacae Amarum, 2 qian), Chaihu (Radix Bupleuri, 5 fen), Tianhuafen (Radix Trichosanthis, 2 qian), Xixin (Herba Asari, 5 fen), Chuanxiong (Rhizoma Chuanxiong, 3 qian), Ganhua Ju (Flos Chrysanthemi Indici, 5 qian), Bohe (Herba Menthae Haplocalycis, 8 fen), Shengdi (Radix Rehmanniae Preparata, 5 qian), Tiandong (Herba Asparagi, 3 qian), Gancao (Radix Glycyrrhizae Uralensis, 1 qian), Baizhi (Radix Angelicae Dahuricae, 3 fen). Decoct in water and take orally. After one dose, vision merges into one; after two doses, full recovery is achieved.
This formula consists entirely of herbs that benefit the Liver, not those that benefit the Brain. It is unknown that benefiting the Brain requires adding Essence (Jing), and adding Essence requires nourishing the Kidney. However, nourishing the Kidney to benefit the Brain does not quickly supplement Liver Qi. It is more appropriate to directly tonify the Liver and assist with herbs that dispel pathogenic factors. Since Brain Qi is insufficient, pathogens can reside there; without dispelling pathogens, merely tonifying Essence in the Brain is indeed unhelpful. Treating the Liver is precisely how one benefits the Brain. This condition can also be treated with Butongshen Dan (Tonify Pupil Spirit Pill): Danggui (Radix Angelicae Sinensis), Baishao (Radix Paeoniae Alba) (each 1 liang), Yuliren (Semen Pruni Armeniacae Amarum), Hei Jingjie (Herba Schizonepetae Preparata), Danpi (Cortex Moutan) (each 3 qian), Maidong (Radix Ophiopogonis), Chuanxiong (Rhizoma Chuanxiong), Weirui (Rhizoma Polygonati Odorati) (each 5 qian), Xixin (Herba Asari, 5 fen). Decoct in water and take orally. Two doses result in cure.
Some patients, after suffering from eye disease, frequently see birds and insects flying before their eyes; upon attempting to catch them, nothing is found. People consider this strange, but do not realize it is not strange; rather, it is due to Blood deficiency in the Liver and Gallbladder, with Phlegm (Phlegm turbidity) causing obstruction. The Liver and Gallbladder belong to Wood. If there is no Blood to moisten the Wood, the Wood Qi becomes excessively dry. Internal dryness must draw moisture from the exterior. However, the Liver and Gallbladder prefer internal moisture for nourishment and dislike external moisture for support. Consequently, external moisture fails to transform into Blood and instead transforms into Phlegm. Blood nourishing the Liver and Gallbladder is beneficial, whereas Phlegm invading them is harmful. Moreover, Blood can enter the interior of the Liver and Gallbladder, but Phlegm finds it difficult to penetrate inside. Since Phlegm remains outside, it obstructs the orifices of the Liver and Gallbladder, preventing Qi from flowing freely. The visual hallucination of flying birds and insects is all caused by the mischief of Phlegm. The treatment method should tonify the Blood of the Liver and Gallbladder while simultaneously resolving the externally obstructing Phlegm. The formula used is Siwu Tang (Four Substances Decoction) with modifications: Shudi (Radix Rehmanniae Preparata, 3 qian), Baishao (Radix Paeoniae Alba, 5 qian), Danggui (Radix Angelicae Sinensis, 1 liang), Chuanxiong (Rhizoma Chuanxiong, 2 qian), Suanzaoren (Semen Ziziphi Spinosae, 5 qian), Qingxiangzi (Semen Celsiae, 3 qian), Fushen (Poria Cum Radix Pinelli, 3 qian), Chenpi (Pericarpium Citri Reticulatae, 1 qian), Gancao (Radix Glycyrrhizae Uralensis, 1 qian), Banxia (Rhizoma Pinelliae Preparata, 3 qian), Baizhu (Rhizoma Atractylodis Macrocephalae, 2 qian). Decoct in water and take orally. After four doses, the visual hallucinations cease.
This formula uses Siwu Tang (Four Substances Decoction) to nourish the Liver and Gallbladder, and uses Fuling (Poria), Banxia (Rhizoma Pinelliae Preparata), and Baizhu (Rhizoma Atractylodis Macrocephalae) to resolve damp-Phlegm. The addition of Suanzaoren (Semen Ziziphi Spinosae) and Qingxiangzi (Semen Celsiae) is because Qingxiangzi (Semen Celsiae) targets the meridians connecting to the eyes, and Suanzaoren (Semen Ziziphi Spinosae) removes mental confusion. When Heart Qi is clear, Phlegm is easily expelled; when the ocular meridians are bright, pathogens naturally dissipate. However, using only these two herbs without combining them with the previous ingredients would fail to achieve a decisive victory through unconventional means.
Using Xiangrong Tang (Prosperity Decoction) for this condition is also excellent. Danggui (Radix Angelicae Sinensis), Baishao (Radix Paeoniae Alba), Shengdi (Radix Rehmanniae Preparata) (each 1 liang), Maidong (Radix Ophiopogonis, 5 qian), Baijiezi (Semen Mustardae), Fuling (Poria) (each 3 qian), Beimu (Bulbus Fritillariae Cirrhosae, 1 qian), Chaihu (Radix Bupleuri, 5 fen). Decoct in water and take orally. Ten doses result in full recovery.
After some patients suffer from eye pain, the whites of both eyes turn completely black. There is no pain, yet vision remains normal. Hair stands stiffly like iron rods, the person appears dazed as if drunk, speaking and acting not at all. People consider this a symptom of rebellious Blood (Blood stagnation rising), but who knows it is actually Kidney Pathogens attacking the Heart? The Heart belongs to Fire, and the Kidney belongs to Water. These two meridians seem to overcome each other, yet Heart Fire cannot thrive without Kidney Water. If Kidney Water does not ascend to communicate with the Heart, the Heart will inevitably suffer from restlessness. Although Kidney Water can only assist the Heart, it should not overly bully it. When Kidney Qi attacks the Heart, it originally intends to save the Heart from dryness; however, if there is pathological Water in the Kidneys, it carries this along to "nourish" the Heart, thereby injuring it. When the Heart is injured by Kidney Pathogens, it is essentially a fatal condition, yet the patient does not die but instead presents with blackness in the eyes. This is because the Kidney comes to rescue the Heart, not to attack it. The Heart fears the Kidney Pathogen but dares not openly expose the Kidney's fault. The whites turning black, making red and white indistinguishable, and hair standing erect are signs of extreme anger/dread. The dazed, drunken appearance, silence, and inaction are signs of being overly constrained, leaving no recourse. The treatment method should break through barriers directly, urgently saving the Heart Monarch from peril, and expelling and cleansing Kidney Pathogens to restore order. The formula used is Zhuanzhi Tang (Transform and Treat Decoction): Fuling (Poria, 5 qian), Renshen (Radix Ginseng, 5 qian), Fuzi (Radix Aconiti Lateralis Preparata, 2 qian), Wulingzhi Mo (Endothelium Corneum Gigeriae Galli Pulveratum, 2 qian), Changpu (Rhizoma Acori Tatarinowii, 1 qian), Baijiezi (Semen Mustardae, 3 qian), Baizhu (Rhizoma Atractylodis Macrocephalae, 5 qian), Liangjiang (Rhizoma Alpiniae Offinarum, 1 qian). Decoct in water and take orally. After one dose, the dazed state clears; after two doses, hair softens; after three doses, blackness resolves; after four doses, full recovery is achieved.
Pathogens in the Kidney are merely Cold-Dampness Qi. Using acrid, warm, and drying agents naturally facilitates the expulsion of pathogens. Furthermore, assisted by generals who breach gates (potent herbs) and guides who lead the way (meridian-guiding herbs), is it not possible to restore health in an instant and quell chaos immediately?
Using Lishui Yixin Dan (Benefit Heart and Promote Water Elimination Pill) for this condition is also good. Fuling (Poria), Renshen (Radix Ginseng), Yiren (Semen Coicis), Bajitian (Radix Morindae Officinalis) (each 5 qian), Baijiezi (Semen Mustardae), Rougui (Cortex Cinnamomi) (each 3 qian), Baizhu (Rhizoma Atractylodis Macrocephalae, 1 liang). Decoct in water and take orally. Four doses result in full recovery.
Some patients experience amenorrhea (menstrual obstruction). Suddenly, after three months, the eyes become red and swollen, with pain like needle pricks. People believe this is due to Blood deficiency failing to nourish the eyes, but who knows it is actually Blood obstruction causing eye pain? Amenorrhea seems to be a symptom of Blood exhaustion; however, if Blood is excessively abundant, Liver Qi becomes blocked and stagnant. Since menstruation does not flow, Heat has no outlet to vent downward and instead accumulates upward. Since the orifice of the Liver opens to the eyes, the Heat travels to the Liver and causes eye pain. In such cases, the Liver pulse must be large and forceful, or wiry and slippery, certainly not fine, choppy, faint, slow, or weak. The treatment method should not tonify Blood to aid Heat, but should unblock menstruation to drain Liver Fire. The formula used is Kaiyong Tang (Open Obstruction Decoction): Honghua (Flos Carthami Tinctorii, 3 qian), Dangguiwei (Cauda Radix Angelicae Sinensis, 3 qian), Niuxi (Radix Achyranthis Bidentatae, 2 qian), Taoren (Semen Persicae, 14 pieces), Chaihu (Radix Bupleuri, 2 qian), Danpi (Cortex Moutan, 3 qian), Dahuang (Radix et Rhizoma Rhei, 1 qian), Xiangfu (Rhizoma Cyperi Rotundi, 1 qian), Yujin (Rhizoma Curcumae Longae, 3 qian), Tianhuafen (Radix Trichosanthis, 2 qian), Yuanhusuo (Rhizoma Corydalis Yanhusuo, 1 qian). Decoct in water and take orally. After one dose, menstruation flows; after another dose, the eyes heal.
This formula does not treat the eyes directly but focuses on unblocking menstruation. Once menstruation flows, Heat dissipates; once Heat dissipates, the eyes settle.
This condition can also be treated with Xieyong Dan (Drain Obstruction Pill): Danggui (Radix Angelicae Sinensis, 1 liang), Honghua (Flos Carthami Tinctorii, 5 qian), Dahuang (Radix et Rhizoma Rhei, 2 qian), Shengdi (Radix Rehmanniae Preparata, 5 qian), Jingjie (Herba Schizonepetae, 3 qian), Taoren (Semen Persicae, 10 grains), Danpi (Cortex Moutan, 3 qian), Chao Zhizi (Fructus Gardeniae Jasminoidis Stir-fried, 2 qian). Decoct in water and take orally. After one dose, Blood flows; after two doses, eye swelling completely subsides; a third dose is unnecessary.
