《黄帝内经》中说：瞳孔上视，是太阳经气不足的表现；两眼向上固定不能转动（戴眼），是太阳经气已经竭绝的表现。太阳经脉之气终绝时，会出现两眼上视、身体向后反折、四肢抽搐的症状。
泻青丸（兼治小儿肝脏实热证，表现为手摸下巴乱抓东西、眼睛直视但不抽搐；若兼得心经热邪则出现抽搐；身体向后反折强直；眼内眦发青；或因脏腑之气泄脱，服用其他药物无效；脾胃长期虚弱导致眼睛突然发红肿胀疼痛等症，均可治疗。）
药材组成：龙胆草、当归、川芎、羌活、山栀仁、防风、大黄（用湿纸包裹后煨制，各等分）。
将上述药材共同研磨成细末，用炼蜜制成丸子，大小如鸡头子。每次服用一丸，用竹叶煎汤送服化开；或者用砂糖水送服化开也可以。如果是治疗成人，每次服用二至三钱，根据情况酌情服用。
肝主司风木之气，少阳胆是其相表里的腑。少阳经脉循行于两胁部位。风邪与热邪相互干扰，所以患者无法安稳躺卧。此方名为“泻青”，意在清泻肝胆之火。龙胆草味道苦而浓厚，所以能入厥阴肝经以清泻肝火。少阳火气实证者，头部两侧角部必然疼痛，所以辅以川芎来止痛。少阳火气郁结者，必然产生烦躁情绪，所以辅以栀子来清热除烦。肝被称为“将军之官”，当风邪肆虐、火势炽盛时，病情势必要通过强硬手段才能治愈，所以又使用大黄来通腑泄热。使用当归身的原因，是为了滋养血液，防止其被风热所燥伤。再次使用羌活、防风，是因为这两味药都是升散性质的药物，体现了“火郁则发之”、“木郁则达之”的治疗原则，从而上下分消风热之邪，这都是为了达到泻火的目的。

以上前十味药材，分别单独研磨至极细，混合在一起。用酒煮面糊调和做成丸子，大小如鸡头。每次服用一丸，用薄荷煎汤，并配合酒磨服下。老年人服用半丸。十岁以下儿童，分为四次服用，用蜜水磨服。四岁以下儿童，分为五次服用。未满一岁的婴儿，可分为七次服用。如果牙关紧闭，可用器具撬开灌服。
The *Classic of Medicine* (*Huangdi Neijing*) states: When the pupils are elevated, it indicates a deficiency of the Taiyang (Greater Yang) channel. When the eyes are fixed upward and cannot move (Daiyan), it indicates that the Qi of the Taiyang channel has been exhausted. At the termination of the Taiyang channel's Qi, symptoms include upward-fixed eyes, opisthotonos (body bending backward), and convulsions.
Xie Qing Wan (Cyan-Draining Pill) (Also treats pediatric Liver-Gallbladder Excess-Heat patterns, manifesting as hand movements picking at the chin, staring straight ahead without convulsions; if Heart-Heat is involved, convulsions occur; opisthotonos with rigidity; bluish discoloration at the inner canthus; or leakage of Zang-Fu Qi unresponsive to other medications; sudden redness, swelling, and pain of the eyes due to long-term Spleen-Stomach deficiency. All these conditions may be treated.)
Ingredients: Longdan Cao (Gentianae Radix), Dang Gui (Angelicae Sinensis Radix), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Qiang Huo (Notopterygii Rhizoma et Radix), Shan Zhi Ren (Gardeniae Semen), Fang Feng (Saposhnikoviae Radix), Da Huang (Rhei Radix et Rhizoma) (wrapped in wet paper and roasted, equal parts).
Grind all ingredients into a fine powder. Mix with refined honey to form pills the size of a corn kernel. Take one pill per dose, dissolved in decoction of Zhu Ye (Bambusae Folium) or sugar water. For adults, take 2–3 qian per dose, adjusted according to condition.
The Liver governs Wind. The Shaoyang Gallbladder is its interior-exterior paired organ. The Shaoyang meridian runs through the hypochondrium. When Wind and Heat interfere with each other, the patient cannot lie down comfortably. This formula is named "Xie Qing" (Cyan-Draining), meaning to drain the Liver and Gallbladder. Longdan Cao (Gentianae Radix) is bitter and potent, entering the Jueyin Liver meridian to drain Liver fire. In cases of Shaoyang Fire Excess, pain at the temporal region is inevitable, so Chuan Xiong (Ligustici Chuanxiong Rhizoma) is added as an assistant to relieve pain. In cases of Shaoyang Fire Stagnation, irritability arises, so Zhi Zi (Gardeniae Fructus) is added to clear heat and calm irritability. The Liver is called the "General"; when Wind is rampant and Fire is blazing, the condition is difficult to treat gently, so Da Huang (Rhei Radix et Rhizoma) is used to purge accumulated heat. Dang Gui (Angelicae Sinensis Radix) body is used to nourish Blood and prevent it from being dried by Wind-Heat. Qiang Huo (Notopterygii Rhizoma et Radix) and Fang Feng (Saposhnikoviae Radix) are used again because both are ascending and dispersing herbs, embodying the principles of "stagnant Fire should be dispersed" and "stagnant Wood should be unblocked," thereby dispersing Wind-Heat from above and below, which serves to drain the pathogenic factors.
He Taishi Niuhuang Wan (Grand Preceptor Cow-bezoar Pill) (Treats sudden stroke in men and women of all ages, characterized by dizziness, collapse, mental confusion, loss of consciousness, locked jaw, staring eyes; phlegm-saliva obstruction in the chest, diaphragm, and throat; and various epilepsy attacks with limb convulsions, facial deviation, and neck/back rigidity.)
Ingredients: Shi Yan (Fossilia Os Draconis) (calcined with vinegar nine times, sifted), Xiong Huang (Realgar) (finely ground, sifted), She Huang (Fossile Corvi) (calcined with vinegar nine times, sifted), Chen Sha (Cinnabaris) (finely ground, sifted), Ci Shi (Magnetitum) (calcined with vinegar nine times, sifted), Shi Lv (Malachite) (finely ground, 1 liang each), Qing Fen (Calomelas) (finely ground), Niu Huang (Bovis Calculus) (finely ground), Fen Shuang (Hydrargyri Oxydum Rubrum) (finely ground), She Xiang (Moschus) (finely ground, 5 qian each), Jin Bo (Lamina Aurea), Yin Bo (Lamina Argenti) (each 100 sheets, used for coating).
The first ten ingredients above are separately ground to an extremely fine powder and mixed together. Use wine-boiled wheat paste to form pills the size of a corn kernel. Take one pill per dose, taken with Mint decoction and wine. Elderly patients take half a pill. Children under ten years old divide one pill into four doses, taken with honey-water. Children under four years old divide one pill into five doses. Infants under one year old divide one pill into seven doses. If the jaw is locked, pry it open with a tool and administer the medicine.
