知母 石膏 甘草 粳米 人参
白虎者，西方金神也。五行之理，将来者进，成功者退。知秋金令行，则夏火拱服。石膏甘寒，知母苦寒，
所以吏清肃之令而除炎热。诗曰∶大暑驱酷吏，清风来攻人。正睽此汤之谓。然啜则啜矣，胃气不能无损，故用
人参以挟气，甘草粳米以和胃。热淫阳明，津液内燥，睑肿头痛，此方主之。
石膏半生半熟一味为散，淡竹叶、麦门冬浓煎，调二三钱，功效不相上下。
诗曰∶睑肿头痛风木侮，草汁调和煎白虎，知母不奈石膏凉，安排人参粳米补。
犀角尖 生地黄 牡丹皮 白芍药
诸见血、血瘀、血热，用此四者。心主血，犀角所以凉心。肝纳血，芍药所以平肝。火炎能载血上行，丹皮
去耗血之火。血涸能致火内燔，地黄滋养阴之血。若夫血怯则瘀，瘀则热发，当问症审脉，变化无方，非此所能
统辖。
诗曰∶犀角地黄，牡丹芍药，血见而稀，血瘀而薄，血热而微，血行而却，既饮再煎，妙不自觉。
升麻 当归 黄连 牡丹皮 生地黄（各等分） 一方加石膏。
内睑肿实，痛牵头脑，此方主之。
内睑责阳明，肿责血热，痛责火盛。升麻、黄连能泻火，丹皮、生地能凉血。乃当归之用，所以益阴，使阳
不得独亢。石膏之加，所以清胃，使病不难勇退。
诗曰∶清胃散主当归，升麻连地牡丹皮，或益石膏平气热，阳明症就此中推。
白虎，是西方金神（代表秋季肃杀之气）。五行的规律是：新气将进，旧气当退。知晓秋金主令之时，夏季的火热之气便会拱卫服从。石膏味甘性寒，知母味苦性寒，所以能执行清肃的命令而消除炎热。《诗经》说：“大暑驱除酷吏，清风来攻袭人。”正是形容此汤剂的功效。然而，虽然服用有效，但胃气难免受损，所以用人参来扶助正气，用甘草和粳米来调和胃气。热邪淫溢于阳明经，导致体内津液干燥，出现眼睑肿胀、头痛等症状，此方主治。
石膏一半生用一半熟用，单味药研成散剂，用淡竹叶、麦门冬浓煎汤，调服二三钱，功效不相上下。
诗曰：“眼睑肿胀头痛因风木相侮，用草汁调和煎煮白虎汤，知母难以承受石膏之凉，安排人参粳米以补益。”
凡是见到出血、血瘀、血热的症状，使用这四味药。心主血脉，犀角用来清心凉血。肝贮藏血液，芍药用来平抑肝阳。火气炎上能带动血液上行，牡丹皮去除耗伤阴血的虚火。血液枯竭会导致内火燔灼，生地黄滋养阴血。至于血虚则导致血瘀，血瘀则引发发热，应当询问症状、审察脉象，灵活变化方药，不是此方所能统辖的。
诗曰：“犀角地黄，牡丹芍药，见血则稀，血瘀则薄，血热则微，血行则退，既已饮用再行煎煮，妙处自然不觉。”
内眼睑肿胀属实证，疼痛牵连头脑，此方主治。
内眼睑归属于阳明经，肿胀责之于血热，疼痛责之于火盛。升麻、黄连能泻火，丹皮、生地能凉血。至于当归的作用，是用来益阴，使阳气不至于独自亢盛。加入石膏，是为了清胃热，使病情不难迅速消退。
Rhizoma Anemarrhenae (Zhimu), Gypsum Fibrosum (Shigao), Radix Glycyrrhizae (Gancao), Semen Oryzae Sativae (Jingmi), Radix et Rhizoma Ginseng (Renshen).
Baihu (White Tiger) refers to the Metal Spirit of the West, representing the autumnal purging qi. The principle of the Five Elements dictates that as new qi advances, old qi must retreat. When the command of Autumn Metal is in effect, the summer fire submits and obeys. Gypsum Fibrosum is sweet and cold; Rhizoma Anemarrhenae is bitter and cold. Thus, they execute the command of purification and clearness, eliminating intense heat. The *Classic of Poetry* states: "Great heat drives away the cruel officials, cool breeze comes to attack." This precisely describes the efficacy of this decoction. However, although it is effective, the Stomach Qi may inevitably be damaged; therefore, Radix et Rhizoma Ginseng is used to support the healthy qi, while Radix Glycyrrhizae and Semen Oryzae Sativae are used to harmonize the Stomach. When pathogenic heat floods the Yangming channel, causing internal dryness of body fluids, resulting in symptoms such as eyelid swelling and headache, this formula is indicated.
Gypsum Fibrosem should be half raw and half calcined, ground into a powder. Administer 2-3 qian by mixing with a strong decoction of Herba Lophatheri (Danzhuye) and Radix Ophiopogonis (Maidong); the efficacy is comparable.
The poem states: "Eyelid swelling and headache caused by Wind Wood insulting [Metal]; use herbal juice to harmonize and decoct Baihu Tang; Rhizoma Anemarrhenae cannot withstand the coldness of Gypsum Fibrosum; arrange Radix et Rhizoma Ginseng and Semen Oryzae Sativae to tonify."
Cornu Bubali (Xijiao), Radix Rehmanniae Preparata (Shengdihuang), Cortex Moutan (Mudanpi), Radix Paeoniae Alba (Baishaoyao).
For conditions involving bleeding, blood stasis, and blood heat, these four herbs are used. The Heart governs the blood vessels; Cornu Bubali cools the Heart. The Liver stores blood; Radix Paeoniae Alba soothes the Liver. Flaming fire can carry blood upward; Cortex Moutan removes the fire that consumes blood. Blood depletion leads to internal blazing fire; Radix Rehmanniae Preparata nourishes Yin blood. As for blood deficiency leading to stasis, and stasis generating heat, one must inquire about symptoms and examine the pulse, varying the prescription flexibly; this single formula cannot cover all cases.
The poem states: "Cornu Bubali and Radix Rehmanniae Preparata, Cortex Moutan and Radix Paeoniae Alba; when blood appears, it becomes sparse; when blood stasis occurs, it becomes thin; when blood heat exists, it becomes mild; when blood flows, it recedes. After drinking and re-decocting, the subtlety is naturally perceived."
Rhizoma Cimicifugae (Shengma), Radix Angelicae Sinensis (Danggui), Radix Coptidis (Huanglian), Cortex Moutan (Mudanpi), Radix Rehmanniae Preparata (Shengdihuang) (equal parts); another variation adds Gypsum Fibrosum.
Internal eyelid swelling presenting as excess syndrome, with pain radiating to the head, is treated with this formula.
The internal eyelid corresponds to the Yangming channel; swelling is attributed to blood heat; pain is attributed to excessive fire. Rhizoma Cimicifugae and Radix Coptidis clear fire; Cortex Moutan and Radix Rehmanniae Preparata cool blood. The role of Radix Angelicae Sinensis is to benefit Yin, preventing Yang from hyperactivity alone. The addition of Gypsum Fibrosum clears Stomach heat, making it easy for the disease to recede rapidly.
The poem states: "Qingwei San primarily contains Radix Angelicae Sinensis, Rhizoma Cimicifugae, Radix Coptidis, Radix Rehmanniae Preparata, and Cortex Moutan; or add Gypsum Fibrosum to calm Qi heat; Yangming channel syndromes are deduced within this context."
