栀子（十五枚，擘） 甘草（一两，炙） 黄柏（二两） 上三味，以水四升，煮取升半，去渣，分温再服。
伤寒身黄发热者，栀子柏皮汤主之。《本草》∶柏皮散脏腑结热黄胆。
枳实（三枚，炙） 栀子（十四枚，擘） 豉（一升，绵裹） 上三味，以清浆水七升，空煮。又一煮法，浆水即
淘米之泔水，久贮味酸为佳。取四升，纳枳实、栀子，煮取二升，下豉，更煮五、六沸，去渣，分温再服，
覆令微似汗。此不取吐而取汗。
大病瘥后劳复者，劳复乃病后之余症，不在吐法，故取微汗。枳实栀子豉汤主之。劳复因病后气虚，
邪气又结于上焦，其症不一，故不着其病形，惟散其上焦之邪足矣，后人以峻补之剂治劳复，则病变百出
矣。若有宿食者，纳大黄如博棋子大五、六枚。此指劳复之有宿食者，治食复之法，亦在其中矣。
可吐篇云∶宿食在上脘，当吐之。
按∶栀子汤加减七方，既不注定何经，亦不专治何误，总由汗吐下之后，正气已虚，尚有痰涎滞气，凝
结上焦，非汗下之所能除。《经》所云∶“在上者因而越之。”则不动经气而正不重伤，此为最便，乃不易之
法也。古方栀子皆生用，故入口即吐。后人作汤以栀子炒黑，不复作吐，全失用栀子之意，然服之于虚烦症，
亦有验，想其清肺除烦之性故在也。终当从古法生用为妙。
栀子（十五枚，掰开） 甘草（一两，炙烤） 黄柏（二两） 以上三味药，用水四升，煮取一升半，去掉药渣，分两次温服。
伤寒病出现身体发黄且发热的，用栀子柏皮汤主治。《本草》记载：柏皮散能清除脏腑积聚的热邪及黄疸。
枳实（三枚，炙烤） 栀子（十四枚，掰开） 豆豉（一升，用丝织品包裹） 以上三味药，用清浆水七升，先单独煮沸。另一种煮法是：浆水就是淘米的水，久存后味道变酸为佳。取四升，放入枳实、栀子，煮取二升，再加入豆豉，继续煮沸五六次，去掉药渣，分两次温服，服药后覆盖衣被使身体微微出汗。这种方法不是通过催吐，而是通过发汗来治疗。
大病初愈后因劳累而复发的，劳复是指病后残留的症状，不属于催吐法的适应证，所以采用微汗法。用枳实栀子豉汤主治。劳复是因为病后正气虚弱，邪气又结聚在上焦，症状表现不一，所以不具体描述病症形态，只要疏散上焦的邪气即可。后人用峻猛的补剂治疗劳复，会导致病情变化百出。如果有宿食停滞，加入如博棋子大小五到六枚的大黄。这是针对有宿食的劳复患者，其中也包含了治疗食复的方法。《可吐篇》说：宿食在上脘，应当用催吐法。
按语：栀子汤加减共有七方，既不固定针对某一经络，也不专门治疗某种误治，总归是汗、吐、下法之后，正气已经虚弱，仍有痰涎和滞气凝结在上焦，非发汗或攻下之法所能去除。《内经》所说：“病位在上者，因势利导使其涌越。”这样不扰动经络之气而正气不受重伤，这是最便捷的方法，也是不可更改的法度。古方中栀子皆生用，所以入口即引起呕吐。后人将栀子炒黑做汤剂，不再引起呕吐，完全失去了使用栀子的本意，然而服用于虚烦症，也有疗效，想是其清肺除烦的药性仍在。最终仍应遵循古法生用为妙。
Zhi Zi (15 pods, broken open) Gan Cao (1 liang, honey-fried) Huang Bo (2 liang) The above three herbs are decocted in 4 sheng of water to obtain 1.5 sheng. Strain the dregs and divide into two warm doses.
For Taiyang disease presenting with jaundice and fever, Zhi Zi Bai Pi Tang (Gardenia and Phellodendron Decoction) is the primary formula. *Ben Cao* records: Bai Pi San (Phellodendron Bark Powder) clears heat accumulation in the zang-fu organs and treats jaundice.
Zhi Shi (3 pieces, honey-fried) Zhi Zi (14 pods, broken open) Chi Xiao Dou (1 sheng, wrapped in silk) The above three herbs are decocted in 7 sheng of Qing Jiang Shui (clear fermented rice water), boiled first alone. Another method for preparing Qing Jiang Shui: it is the water from washing rice; it is best when stored for a long time until it becomes sour. Take 4 sheng, add Zhi Shi and Zhi Zi, boil to obtain 2 sheng, then add Chi Xiao Dou, boil for five or six more boils, strain the dregs, and divide into two warm doses. Cover the patient to induce a slight sweat. This method aims at inducing sweating rather than vomiting.
For relapse due to overexertion after a major illness (Lao Fu), which refers to residual symptoms after illness recovery and is not indicated for emesis, mild sweating is employed. Zhi Shi Zhi Zi Chi Tang (Immature Bitter Orange, Gardenia, and Fermented Soybean Decoction) is the primary formula. Lao Fu occurs because post-illness righteous qi is deficient, allowing pathogenic factors to accumulate in the upper jiao. Symptoms vary, so specific pathological forms are not detailed; dispersing pathogenic factors in the upper jiao suffices. Later practitioners who used potent tonifying agents to treat Lao Fu caused myriad complications. If there is retained food, add Da Huang (Rhubarb Root) in pieces the size of chess pieces, five or six pieces. This addresses Lao Fu with retained food, encompassing methods for treating Shi Fu (relapse due to improper diet). The "Chapter on Emesis" states: "If retained food is in the upper wan (upper stomach), emesis should be induced."
Note: There are seven variations of Zhi Zi Tang formulas. They do not target specific meridians nor exclusively treat specific misapplications of therapy. Generally, after sweating, vomiting, or purging, righteous qi is already deficient, while phlegm-fluids and stagnant qi remain condensed in the upper jiao, which cannot be removed by sweating or purging. As stated in the *Classic*: "For pathogens located above, use induction to cause upward expulsion (vomiting)." This approach does not disturb meridian qi and prevents further injury to righteous qi, making it the most convenient and unchangeable method. In ancient prescriptions, Zhi Zi was always used raw, causing immediate vomiting upon ingestion. Later practitioners stir-fried Zhi Zi black for decoctions, preventing vomiting, thereby completely losing the original intent of using Zhi Zi. However, it remains effective for deficiency-heat irritability, likely because its property of clearing lung heat and relieving irritability persists. Ultimately, following the ancient method of using it raw is superior.
