泪液是肝脏的津液，风气流动则水液随之流动，风邪扰动就会导致流泪。另外，肝热也会导致多泪，就像烧制竹沥时，用火烘烤使汁液流出一样；迎风流泪，则是风与火相结合所致。火热发动，风邪上冲，二者相互搏结导致流泪，采用疏风散火的方法虽然是正确的治疗原则，但也应当仔细辨别肝经的虚实情况。实证使用复目汤加入防风、蔓荆子、何首乌；虚证加入人参。外用霜降后的桑叶煎水，频繁清洗眼部。
复目汤（见前文目赤肿章节）。
凡是眼睛眩晕、多泪、瘙痒难以忍受的，属于风邪致病。风邪扰动肝木，吹嘘鼓舞肝气，所以眩晕不止，因为没有火邪所以不疼痛。治疗以疏风为主，用四物汤加入防风、荆芥、紫苏叶、薄荷各二钱来主治，或者加入蝉蜕、僵蚕。
四物汤（通用方二十三）。
平时眼睛没有其它疾病，外部没有损伤轮廓，内部没有损伤瞳孔，突然失明看不见东西，这是气脱大虚的征候，急需煎煮人参膏或保元汤，大剂量熬成膏剂服用。血脱的患者也按照这种方法治疗。医经说：“血脱益气”就是这个道理。
一、有平素喜欢饮用热酒，导致胃气受伤，污浊的血积聚在其中而致病的，必定形体壮实但脉象涩滞，使用四物汤加入苏叶，服用数剂痊愈。（谨按：丹溪医案中人参下有“末”字。）
一、有因为感受阴湿之气，胃阳受到困阻，突然视物不见，或者有时稍微看见但不清晰，其人必定食欲减退、精神疲倦，脉象缓大而无力，使用白术为君药，黄芪、茯苓为臣药，附子为使药，服用十余剂痊愈。
一、有每次睡醒后，视物不明或眼睛红肿，过很久才痊愈的，这是血热所致。用地黄汁浸泡粳米半升，晒至透干，再浸泡再晒三次，用瓷瓶煎汤煮沸，放入地黄米四、五匙，煮成稀薄的粥汤，待温度适宜，在半饱饭后，喝三盏然后睡觉，数日痊愈。或者使用四物汤去掉川芎，加倍生地黄，加入牡丹皮、黄芩（酒炒）各一钱，水煎临睡前服用，数剂痊愈。

Tears are the fluid of the Liver. When wind moves, water flows; when wind stirs, tears flow. Furthermore, excessive heat in the Liver causes excessive tearing, similar to how bamboo sap is extracted by fire; tearing upon exposure to wind is due to the combination of wind and fire. When fire erupts and wind rushes upward, they contend with each other causing tearing. Although dispersing wind and clearing fire is the correct treatment principle, one must also carefully examine the deficiency or excess of the Liver channel. For excess patterns, Fumu Tang (Restore Vision Decoction) is used with added Fangfeng (Saposhnikovia Root), Manjingzi (Vitex Fruit), and Shouwu (Polygonum Multiflorum Root); for deficiency patterns, Renshen (Ginseng Root) is added. Externally, mulberry leaves harvested after frost are decocted in water, and the eyes are frequently washed with it.
Fumu Tang (See previous section on Red and Swollen Eyes).
Whenever the eyes feel dizzy, tear excessively, and itch unbearably, it is due to wind. Wind disturbs Liver wood, blowing and stirring it, thus causing continuous dizziness; because there is no fire, there is no pain. The treatment focuses on dispersing wind, using Siwu Tang (Four Substances Decoction) with added Fangfeng (Saposhnikovia Root), Jingjie (Schizonepeta Spike), Ziye (Perilla Leaf), and Bohe (Mint Leaf), each 2 qian, as the main prescription, or adding Chantui (Cicada Slough) and Jiangcan (Bombyx Batryticatus).
Siwu Tang (General Formula 23).
If the eyes have no other diseases normally, the external contour is not damaged, and the internal pupil is not injured, but sudden blindness occurs, this is a sign of Qi collapse and severe deficiency. It is urgent to decoct Renshen Gao (Ginseng Paste) or Baoyuan Tang (Preserve Origin Decoction) in large doses and administer as paste. For blood collapse, treat similarly. The Classics state: "For blood collapse, tonify Qi."
1. Some who habitually drink hot wine injure Stomach Qi, causing turbid blood to accumulate within. Their physique is solid but the pulse is choppy. Use Siwu Tang (Four Substances Decoction) with added Ziye (Perilla Leaf) for several doses to cure. (Note: In Danxi's medical cases, there is a character "mo" [powder] after Renshen.)
1. Some who contract Yin-dampness find their Stomach Yang trapped, suddenly losing vision or seeing dimly at times. These patients likely have reduced appetite, mental fatigue, and a slow, large, and forceless pulse. Use Baizhu (Atractylodes Macrocephala Rhizome) as the sovereign herb, Huangqi (Astragalus Root) and Fuling (Poria) as minister herbs, and Fuzi (Prepared Aconite Lateral Root) as envoy herb. Cure after taking more than ten doses.
1. Some experience unclear vision or redness and swelling upon waking from sleep, which resolves after a long time. This is due to Blood heat. Soak Banliang (half sheng) of Jingmi (Japonica Rice) in Shengdi Zhi (Rehmannia Juice), sun-dry until thoroughly dry, then soak and dry again three times. Decoct in a porcelain bottle until boiling, add four or five spoons of Rehmannia rice, and cook into a thin porridge soup. When warm, drink three cups after being half-full of food, then sleep. Cure in a few days. Alternatively, use Siwu Tang (Four Substances Decoction) removing Chuanxiong (Ligusticum Wallichii Rhizome), doubling Shengdi (Rehmannia Root), and adding Mudanpi (Tree Peony Bark) and Huangqin (Scutellaria Root) fried in wine, each 1 qian. Decoct in water and take before bed. Cure in a few doses.
