迎风流泪，翳膜遮睛。
木贼为磋擦之需，故入肝而伐木。去节者善发汗，中空而轻，有升散之力也。

味苦、涩，性大寒，无毒。入肝、胆二经。恶地黄。酒浸炒。
大苦大寒，性沉而降，主肝胆热邪，耳鸣头胀。清下焦湿火，阴痒生疮。火炎上而咽痛，
湿
蕴中以目黄。小儿高热惊痫，成人伤寒发狂。
禀纯阴之气，但以荡涤肝胆之热为职。
龙胆大苦大寒，苟非气壮实热之证，不能率尔轻投。
味咸，性平，无毒。入肝经（肝脏所属经络）。
治疗青盲内障（视力模糊、眼内混浊）、翳膜遮睛（角膜云翳遮挡视线）。赤肿眶烂（眼眶红肿溃烂），泪出羞明（流泪且畏光）。
这是马蹄决明，因为“决”有疏通明目之意，所以得名此名。另有草决明、石决明与之功效相同，但各自是不同的品种。
石决明独与云母石药性相反。
味甘、性平，无毒。入肝经。用酒润湿，焙干。
滋养营血，退翳开光（消除翳障，恢复视力）。治疗成人迎风流泪畏光，小儿痘疳攻眼（痘疮或疳积引起的眼部病变）。
独入东方（对应肝脏），作为清除热邪、调和营血的作用，所以除了治疗目疾之外，没有其他特长。
味甘，性温，无毒。入肝经。汤水浸泡，去皮、尖，水煮后，研磨成膏。
退翳膜赤筋（消除眼角红丝和翳膜），理伤泪出（调理外伤引起的流泪）。破除心下结聚的痰饮，消除腹中痞气（腹部胀满不适）。
外能疏散风邪，内能清热，肝气调和则眼病痊愈。痰饮痞块都是热邪作祟，所以适宜一并主治。
如果眼疾不是由风热引起，而是由于虚证导致的，则不要使用。
味甘、苦，性平，无毒。入肝经。
迎风流泪，翳膜遮睛。

木贼，多服会损伤肝脏，不宜长期服用。
味辛，性寒。入肝经。忌恶白薇、白蔹，淘洗干净，焙干使用。
明目活血、行瘀清积（消散瘀血，清除积滞）。
即蝙蝠的粪便，因为蝙蝠吃蚊子，其粪便中的砂粒都是蚊子的眼睛，所以治疗眼疾。本草称其能下死胎，那么它攻破血积的功效，有什么可怀疑的呢？
味咸，性平，无毒。入脾、肝二经。
除热平肝，安神明目。治疗惊悸不眠，退遮睛之翳膜。
此物煎汤必须打碎或研成粉末。外用点眼须用水飞法（加水研磨沉淀取极细粉）。

Salty, neutral in nature, non-toxic. Enters the Liver Meridian (Liver Channel).
Treats Qingmang internal cataract (blurred vision and intraocular turbidity) and Yi membrane covering the pupil (corneal opacity obstructing vision). Red swelling and ulceration of the orbital rim, tearing with photophobia (aversion to light).
This is Matijue Ming (Cassiae Semen), named for its ability to "Jue" (clear/resolve) vision. There are also Caojue Ming (Cassiae Fructus) and Shijueming (Haliotidis Concha) with similar efficacy, but they are distinct species.
Shijueming (Haliotidis Concha) is uniquely contraindicated with Yunmushi (Micae Lamina).
Sweet, neutral in nature, non-toxic. Enters the Liver Meridian. Moisten with wine, then roast.
Nourishes Ying (Nutritive Qi) and harmonizes Blood, reduces corneal opacity and restores vision. Treats adults with tearing and photophobia, and children with Dougan attacking the eyes (eye lesions caused by smallpox or malnutrition-related Gan syndrome).
It enters exclusively into the East (corresponding to the Liver), serving to clear heat and harmonize Ying, thus having no other major indications besides treating eye diseases.
Sweet, warm in nature, non-toxic. Enters the Liver Meridian. Soak in decoction, remove skin and tips, boil in water, then grind into paste.
Reduces corneal opacity and red filaments, regulates trauma-induced tearing. Breaks up phlegm stagnation below the heart, removes abdominal distension and Qi stagnation.
Externally it disperses Wind, internally it clears Heat; when Liver Qi is harmonized, eye diseases heal. Phlegm and distension are both caused by Heat pathogens, so it is suitable for treating both.
Do not use if the eye disease is not due to Wind-Heat, but rather due to Deficiency.
Sweet and bitter, neutral in nature, non-toxic. Enters the Liver Meridian.
Tearing upon exposure to wind, corneal opacity covering the pupil.
Mu Zei (Equiseti Herba) is needed for abrasion/polishing, thus entering the Liver to subdue Wood (regulate Liver Qi). Those without nodes are good at inducing sweating; hollow and light, it has ascending and dispersing properties.
Mu Zei damages the Liver if taken in large doses; it should not be used for a long time.
Pungent, cold in nature. Enters the Liver Meridian. Adverse with Baiwei (Bletillae Rhizoma) and Bailian (Ampelopsis Radix). Wash clean, roast before use.
Brightens the eyes, invigorates Blood, moves stasis, and clears accumulation.
It is bat feces. Because bats eat mosquitoes, the gritty particles in the feces are mosquito eyes, hence it treats eye diseases. Materia Medica states it expels dead fetus; thus, its ability to attack blood accumulations is beyond doubt.
Salty, neutral in nature, non-toxic. Enters the Spleen and Liver Meridians.
Clears heat, calms the Liver, soothes the Spirit, and brightens the eyes. Treats palpitations and insomnia, reduces corneal opacity covering the pupil.
When decocting, this substance must be crushed or ground into powder. For external eye application, it requires water levigation (shuifei).

Bitter and astringent, extremely cold in nature, non-toxic. Enters the Liver and Gallbladder Meridians. Adverse with Dihuang (Rehmanniae Radix). Soak in wine and stir-fry.
Extremely bitter and cold, with a sinking and descending nature. It primarily treats Heat pathogens in the Liver and Gallbladder, tinnitus, and head distension. Clears damp-fire from the Lower Jiao, treating genital itching and sores. Fire flaming upward causes sore throat; Dampness accumulating internally causes yellow eyes. High fever with convulsions in children, mania due to Shanghan (Cold Damage) in adults.
Endowed with pure Yin Qi, its primary function is to sweep away Heat in the Liver and Gallbladder.
Longdan (Gentianae Radix) is extremely bitter and cold; unless the condition involves robust constitution and excess Heat, it should not be administered lightly.
