bubble_chart Formula Principles

The impact on influenza viral pneumonia, as reported in "Journal of Traditional Chinese Medicine" 1986(2):58, involved the deconstruction and formulation of the Bupleurum decoction, along with experiments on the effects of each constituent herb on influenza viral pneumonia in mice. The results demonstrated that the complete formula was effective, with only Peony Root showing efficacy among the single herbs. Removing any single herb from the complete formula significantly weakened its overall effect. The relationships among the herbs in the formula are complex: combining two ineffective herbs can produce an effect, combining an ineffective herb with an effective one can enhance the effect, and an ineffective herb can also antagonize an effective one. This suggests connections with mutual reinforcement, mutual assistance, and mutual inhibition.
