Traditional Chinese medicine (TCM) Yi-Fei-Jie-Du-Tang (YFJDT) has shown potential in lung cancer treatment. However, the mechanisms underlying the effects of YFJDT on lung cancer remain unclear. Bioinformatics analysis is conducted to identify potential targets of YFJDT. The impact of YFJDT on hypoxia-inducible factor 1 alpha (HIF1A), ferroptosis, and vasculogenic mimicry (VM) is investigated using xenograft tumor models and A549 cells. Additionally, A549 cells are stimulated with CoCl
