Methods The experimental animals were randomly divided into 5 groups: normal group received no treatment, BMT control group, G-CSF group, Shengxue group, and Shengxue ＋G-CSF group. BMT mouse models were established. Shengxue group, Shengxue ＋G-CSF group were given Shengxuezengbai Decoction. On days 9, 14, 24 after BMT, mice were killed and peripheral blood cells, bone marrow nucleated cells were detected. Histologic
