They differ significantly because of variations in zang-fu organs and meridians involved. Although the specific formulas are not detailed here, the principles are as follows: Different herbs such as Qianghuo, Fangfeng, Chuanxiong, Chaihu, Shengma, Ligusticum, and Xixin are used to promote circulation in respective meridians; different herbs such as Huangqin, Huanglian, Huangbai, Zhimu, Shigao, and Shengdihuang are used to clear fire from respective zang organs; Zexie and Fuling are used to guide dampness downward, allowing pathogens to descend from the heavens; Huangqi is used to tonify qi and promote qi movement. These modifications follow the principle of increasing or decreasing based on the disease condition and should not be rigidly adhered to.
