柴胡 升麻 葛根 羌活 防风（以此五味，升阳达表，使离于阴，则外不寒） 知母 石膏
黄芩（以此三味，引阴下降，使离于阳，则内不热） 猪苓（以分理阴阳，使不得交并） 穿山甲（以引经） 甘草
（以和之） 按此方所指阴阳，俱以本身阴阳之气言，即《内经》阴气上入阳中则恶寒，
阳气下入阴中则恶热之说也。与疟疾寒热之理颇异，而意可相通，故分理而效。又
猪苓利湿降浊也，浊降则清升，亦有分理阴阳之义。
（对于体内有热且大便干结的患者，适宜使用此方。）
人参、柴胡、黄芩、甘草、大黄、当归、芍药，以上药材研为细末，每次服用三钱，加水一碗，生姜三片，煎煮至剩余七分药液，温服。
（对于兼夹痰湿及食物停滞的患者，适宜使用此方。）
柴胡、独活、前胡、黄芩、苍术、厚朴、半夏曲、白茯苓、藿香、甘草、陈皮，加生姜三片，用水煎煮。气虚者加入人参、白术；饮食不消化者加入神曲、山楂、麦芽。
（对于兼夹湿邪且小便不通利的患者，适宜使用此方。）
猪苓、茯苓、白术、泽泻、桂枝（此方名为五苓散），与小柴胡汤合用。
（对于有食积、湿痰的患者，适宜使用此方。）
苍术、厚朴、陈皮、甘草（此方名为平胃散），与小柴胡汤合用。
（对于妇女及血虚患者，适宜使用此方。）
当归、生地黄、白芍、川芎（此方名为四物汤），与小柴胡汤合用。
（对于阴阳错杂的患者，适宜使用此方。）
柴胡、升麻、葛根、羌活、防风（用这五味药，提升阳气达于体表，使阳气脱离阴分，则体表不寒冷）；知母、石膏、黄芩（用这三味药，引导阴气下降，使阴气脱离阳分，则体内不发热）；猪苓（用以分理阴阳，使阴阳不得交并）；穿山甲（用以引经报使）；甘草（用以调和诸药）。按此方所指的阴阳，都是指人体本身的阴阳之气，即《黄帝内经》中“阴气上入阳中则恶寒，阳气下入阴中则恶热”的说法。这与疟疾寒热往来的机理颇为不同，但意旨可以相通，所以通过分理阴阳而见效。另外，猪苓有利湿降浊的作用，浊气下降则清气上升，也有分理阴阳的含义。
（对于邪气陷入阴分的患者，适宜使用此方。）
使用前方中的前五味药（柴胡、升麻、葛根、羌活、防风）升举下陷的阳气，并使用桃仁、红花、四物汤引导这五味药进入血分，以提取阳气使其外出，同时用猪苓进行分隔。
(For patients with internal heat and constipation, this formula is suitable.)
Ren Shen (Ginseng Radix), Chai Hu (Bupleuri Radix), Huang Qin (Scutellariae Radix), Gan Cao (Glycyrrhizae Radix et Rhizoma), Da Huang (Rhei Radix et Rhizoma), Dang Gui (Angelicae Sinensis Radix), Shao Yao (Paeoniae Radix). The above herbs are ground into powder. Each dose is three qian (approx. 11.25g), boiled in one bowl of water with three slices of fresh ginger, until reduced to seven-tenths of the original volume, and taken warm.
(For patients complicated by phlegm-dampness and food stagnation, this formula is suitable.)
Chai Hu (Bupleuri Radix), Du Huo (Angelicae Pubescentis Radix), Qian Hu (Peucedani Radix), Huang Qin (Scutellariae Radix), Cang Zhu (Atractylodis Rhizoma), Hou Po (Magnoliae Officinalis Cortex), Ban Xia Qu (Pinelliae Fermentatum), Bai Fu Ling (Poria), Huo Xiang (Agastaches Herba), Gan Cao (Glycyrrhizae Radix et Rhizoma), Chen Pi (Citri Reticulatae Pericarpium). Add three slices of fresh ginger and decoct in water. For qi deficiency, add Ren Shen (Ginseng Radix) and Bai Zhu (Atractylodis Macrocephalae Rhizoma); for indigestion, add Shen Qu (Massa Medicata Fermentata), Shan Zha (Crataegi Fructus), and Mai Ya (Hordei Fructus Germinatus).
(For patients complicated by dampness and difficulty in urination, this formula is suitable.)
Zhu Ling (Polyporus), Fu Ling (Poria), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Ze Xie (Alismatis Rhizoma), Gui Zhi (Cinnamomi Ramulus) (This combination is named Wu Ling San [Five-Ingredient Powder with Poria]), combined with Xiao Chai Hu Tang (Minor Bupleurum Decoction).
(For patients with food accumulation and damp-phlegm, this formula is suitable.)
Cang Zhu (Atractylodis Rhizoma), Hou Po (Magnoliae Officinalis Cortex), Chen Pi (Citri Reticulatae Pericarpium), Gan Cao (Glycyrrhizae Radix et Rhizoma) (This combination is named Ping Wei San [Powder to Maintain Equilibrium]), combined with Xiao Chai Hu Tang (Minor Bupleurum Decoction).
(For women and patients with blood deficiency, this formula is suitable.)
Dang Gui (Angelicae Sinensis Radix), Sheng Di Huang (Rehmanniae Radix), Bai Shao (Paeoniae Radix Alba), Chuan Xiong (Ligustici Chuanxiong Rhizoma) (This combination is named Si Wu Tang [Four-Substance Decoction]), combined with Xiao Chai Hu Tang (Minor Bupleurum Decoction).
(For patients with mixed yin and yang patterns, this formula is suitable.)
Chai Hu (Bupleuri Radix), Sheng Ma (Cimicifugae Rhizoma), Ge Gen (Puerariae Lobatae Radix), Qiang Huo (Notopterygii Rhizoma et Radix), Fang Feng (Saposhnikoviae Radix) (These five herbs raise yang and reach the exterior, separating yang from yin, thus relieving chills on the exterior); Zhi Mu (Anemarrhenae Rhizoma), Shi Gao (Gypsum Fibrosum), Huang Qin (Scutellariae Radix) (These three herbs guide yin downward, separating yin from yang, thus relieving heat internally); Zhu Ling (Polyporus) (To differentiate and regulate yin and yang, preventing their mingling); Shan Jia Chuan (Manis Squama) (To guide the herbs to the affected channel); Gan Cao (Glycyrrhizae Radix et Rhizoma) (To harmonize). According to this formula, "yin" and "yang" refer to the body's own yin and yang qi, consistent with the *Huangdi Neijing* [Yellow Emperor's Inner Canon] statement: "When yin qi ascends into yang, there is aversion to cold; when yang qi descends into yin, there is aversion to heat." This differs somewhat from the mechanism of alternating chills and fever in malaria, but the intent is compatible, hence differentiation and regulation of yin and yang yield efficacy. Furthermore, Zhu Ling promotes diuresis and descends turbidity; as turbidity descends, clarity ascends, which also embodies the principle of differentiating yin and yang.
(For patients where pathogenic factors have sunk into the yin level, this formula is suitable.)
Use the first five herbs from the previous formula (Chai Hu, Sheng Ma, Ge Gen, Qiang Huo, Fang Feng) to raise the sunken yang, and use Tao Ren (Persicae Semen), Hong Hua (Carthami Flos), and Si Wu Tang [Four-Substance Decoction] to guide these five herbs into the blood level to extract yang and bring it out, while using Zhu Ling (Polyporus) to separate and regulate.
