Chai Hu (Bupleuri Radix) four liang, Huang Qin (Scutellariae Radix) one liang five qian, Ren Shen (Ginseng Radix) one liang five qian, Ban Xia (Pinelliae Rhizoma) two he and a half (washed), Gan Cao (Glycyrrhizae Radix et Rhizoma) two liang (roasted), Gui Zhi (Cinnamomi Ramulus) one liang five qian. The above nine herbs are decocted with seven sheng of water until three sheng remain; the dregs are removed, and one sheng is taken warm.
Guizhi Tang (Cinnamon Twig Decoction) focuses on resolving the muscle layer, while Chai Hu Tang (Bupleurum Decoction) focuses on harmonizing the interior. Zhang Zhongjing used these two formulas most frequently; they can serve as a balance between exterior and interior conditions, applied flexibly according to circumstances, without any unsuitability.
Chai Hu (Bupleuri Radix) eight liang, Gui Zhi (Cinnamomi Ramulus) two liang (bark removed), Gan Jiang (Zingiberis Rhizoma) two liang, Huang Qin (Scutellariae Radix) three liang, Gua Lou Gen (Trichosanthis Radix) four liang, Mu Li (Ostreae Concha) two liang (calcined), Gan Cao (Glycyrrhizae Radix et Rhizoma) two liang (roasted). The above seven herbs are decocted with twelve sheng of water until six sheng remain; the dregs are removed, and it is boiled again until three sheng remain; one sheng is taken warm.
First, revealing the formula named after herbs from the Three Yang meridians: when the disease is in the Taiyang (Greater Yang) meridian and slightly involves the Jueyin (Terminal Yin) meridian, not only does the Shaoyang (Lesser Yang) pivot fail to transport outward, but also the Yangming (Yang Brightness) becomes obstructed and fails to descend.
Chai Hu (Bupleuri Radix) four liang, Da Huang (Rhei Radix et Rhizoma) two liang, Ren Shen (Ginseng Radix) one liang five qian, Ban Xia (Pinelliae Rhizoma) two he (washed), Sheng Jiang (Zingiberis Rhizoma Recens) one liang five qian (sliced), Da Zao (Jujubae Fructus) six pieces, Long Gu (Fossilia Ossis Mastodi) one liang five qian, Fu Ling (Poria) three liang. The above twelve herbs are decocted with eight sheng of water until four sheng remain; Da Huang (Rhei Radix et Rhizoma) is added, cut into chess-piece sizes, boiled for one or two more boils, the dregs are removed, and it is taken warm.
In formulas treating Foot Meridian diseases but applied to Hand Meridian diseases, Ren Shen (Ginseng Radix), Fu Ling (Poria), Long Gu (Fossilia Ossis Mastodi), Mu Li (Ostreae Concha), and Qian Dan (Lapis Martis) enter the Foot Meridians but can also circulate to the Hand Meridians. The Hand Shaoyin (Lesser Yin) Heart presents with vexation and palpitations...
Sheng Jiang (Zingiberis Rhizoma Recens) four liang (sliced), Gan Jiang (Zingiberis Rhizoma) one liang, Ban Xia (Pinelliae Rhizoma) half sheng (washed), Huang Qin (Scutellariae Radix) three liang, Huang Lian (Coptidis Rhizoma) one liang, Ren Shen (Ginseng Radix) three liang, Gan Cao (Glycyrrhizae Radix et Rhizoma) three liang, Da Zao (Jujubae Fructus) twelve pieces. The above eight herbs are decocted with ten sheng of water until six sheng remain; the dregs are removed, and it is boiled again until three sheng remain; one sheng is taken warm, three times a day.
There are five types of Xiexin Tang (Drain the Epigastrium Decoctions), all generally involving opening stagnation, conducting heat downward, and benefiting the stomach. However, whether deficiency or excess, presence or absence of pathogenic factors, the variations in prescription each have their subtleties.
