The aim of this study was to evaluate differences in the effects of Ephedra sinica Stapf and Fructus Schisandrae Chinensis on angiogenesis in the treatment of bleomycin-induced rat idiopathic pulmonary fibrosis. The rat models were created using bleomycin. The animals were divided into six groups: model, control, Ephedra alone, Schisandrae alone, combination of Ephedra and Schisandrae, and hydrocortisone alone. The treatments were administered for 28 days. After 7 and 28 days, the rats were sacrificed for pathological morphology examination, microvascular density determination,
