The architecture of this formula is complex, and the subject of scholarly debate. Essentially, warm and sweet it tonifies the qi of the middle jiao. Many of the herbs directly raise the qi (Huang Qi, Sheng Ma, Chai Hu) and directly address
the root of the patterns treated by this formula. The use of acrid and sweet Dang Gui is used to enhance blood circulation, which augments the qi. In addition, acrid, bitter, aromatic and warm: Chen Pi regulates qi and aids in the necessary digestion process of the tonifying herbs in the formula.
Though seemingly at odds, to treat intermittent fever with warm herbs, these symptoms are only the manifestation of the pattern, with middle jiao qi deficiency at the root. Note, however that the cool and cold constituents of this formula along with its sweetness help to safely drain
the Yin Fire. Created by Li Dong-Yuan, Bu Zhong Yi Qi Tang employs his strategy to eliminate heat with sweet and warming herbs, and to utilize the multitude of modifications as needed.
