防风(四两) 甘草(二两) 藿香 栀仁(各一两) 石膏(五钱)
黄乃脾之正色。脾之华在睑,脾之窍在唇口。故凡两睑及口中、外有病者,知脾火也。苦能泻火,寒能胜火,
故用栀仁、石膏。香能醒脾,甘能缓脾,故用藿香、甘草。乃防风取其升浮,既能发脾中伏火,又可于土中泻其
金气,使不受母邪为祸。盖一药两用之法,以故倍之。
诗曰∶泻黄散重用防风,草藿栀膏减半充,蜜酒调咽清胃热,下胞痒烂有殊功。
生地黄 木通 淡竹叶 甘草
赤者,火也。导赤者,导其丙丁之火由溺而泄也。然五脏各有火,何以知为丙丁?盖目赤心烦,小水黄赤耳。
故用生地凉心血,竹叶清心气,草稍退心热,佐以木通,则直入
小肠膀胱而泻心表。若他邪相传,须导赤各半汤为当。
黄连 黄芩 知母 栀仁 犀角 滑石 麦冬 甘草梢 人参 茯神 灯心 红枣
热邪传入心经,凉以黄连、犀角、栀子。心热上逼于肺,清以黄芩、知母、麦冬。下移于小肠,泄以滑石、
草稍、灯薪。然心分本虚,邪乃能越经而传。故又以人参、茯神、红枣以补之。
诗曰∶导赤药四味,竹草通生地,本方黄连芩,犀角滑石参,麦草暨栀子,灯薪枣知母,一样下膀胱,爰名
各半汤。
各半义未详,诸书亦未有发明者。
Fangfeng (Saposhnikoviae Radix, 4 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 2 liang), Huoxiang (Agastaches Herba), Zhiren (Gardeniae Semen, 1 liang each), Shigao (Gypsum Fibrosum, 5 qian).
Yellow is the proper color of the Spleen. The Spleen's brilliance manifests in the eyelids, and its orifice is at the mouth and lips. Therefore, any disease occurring in both eyelids and inside/outside the mouth can be known as caused by Spleen Fire. Bitterness can purge fire, and cold nature can overcome fire; thus, Zhiren and Shigao are used. Aromaticity can awaken the Spleen, and sweetness can moderate the Spleen; thus, Huoxiang and Gancao are used. Fangfeng is chosen for its ascending and floating nature; it can both disperse latent fire within the Spleen and drain Metal (Lung) qi within Earth (Spleen), preventing the Mother organ (Heart) from harming it. This is a method of one herb serving two purposes, hence it is doubled.
Poem says: In Xiehuang San, Fangfeng is heavily used; Gancao, Huoxiang, Zhiren, and Shigao are halved. Mixed with honey and wine to swallow, clearing Stomach heat; it has special efficacy for itching and ulceration in the lower organs.
Shengdihuang (Rehmanniae Radix), Mutong (Akebiae Caulis), Danzhuye (Lophatheri Herba), Gancaoshao (Glycyrrhizae Radix et Rhizoma caulis).
Red belongs to Fire. "Daodi" (Guiding the Red) means guiding Bingding Fire (Heart Fire) to excrete through urine. However, all five Zang organs have fire; how do we know it is Bingding Fire? Because of red eyes, vexation, and yellow-red urine. Thus, Shengdihuang is used to cool Heart Blood, Zhu Ye to clear Heart Qi, Gancaoshao to retreat Heart Heat, assisted by Mutong, which directly enters the Small Intestine and Bladder to drain Heart exterior syndrome. If transmitted by other pathogens, Daodige Ban Tang should be appropriate.
Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Zhimu (Anemarrhenae Rhizoma), Zhiren (Gardeniae Semen), Xijiao (Rhinocerotis Cornu), Huashi (Talcum), Maidong (Ophiopogonis Radix), Gancaoshao (Glycyrrhizae Radix et Rhizoma caulis), Renshen (Ginseng Radix et Rhizoma), Fushen (Poria cum Ramus Pini), Dengxin (Junci Medulla), Hongzao (Jujubae Fructus).
When heat pathogen transmits into the Heart Meridian, cooling is achieved with Huanglian, Xijiao, and Zhiren. When Heart heat forces upward into the Lung, clearing is done with Huangqin, Zhimu, and Maidong. When it shifts downward to the Small Intestine, draining is performed with Huashi, Gancaoshao, and Dengxin. However, since the Heart portion is originally deficient, the pathogen can cross meridians to transmit. Therefore, Renshen, Fushen, and Hongzao are used to tonify.
Poem says: Four herbs of Daod San are Zhu Ye, Gancao, Mutong, and Shengdihuang. The original formula adds Huanglian, Huangqin, Xijiao, Huashi, Renshen, Maidong, Gancao, Zhiren, Dengxin, Juxi (Dengxin), and Hongzao. All descend to the Bladder, hence named Ge Ban Tang.
The meaning of "Ge Ban" is unknown, and no books have elucidated it.
