(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.
