The goal of this clinical trial] is to compare the effect of compound E Jiao Jiang(cEJJ）combined with iron decoction on postpartum anemia.The main questions it aims to answer are:

To evaluate the effectiveness of compound E Jiao Jiang(cEJJ） in the treatment of postpartum anemia.

To evaluate the safety of compound E Jiao Jiang(cEJJ） in the treatment of postpartum anemia.

To explore the effect of compound ejiao decoction on improving anxiety, depression, sleep and fatigue in postpartum anemia patients.

Participants will be randomly assigned (like flipping a coin) to either the trial group or the control group (with a 50% chance of being assigned to either group), where the trial group will receive the compound E Jiao Jiang(cEJJ） + ferrous succinate tablet, and the control group will receive the compound E Jiao Jiang(cEJJ）placebo + ferrous succinate tablet. The compound E Jiao Jiang(cEJJ）placebo is the same/similar to the compound E Jiao Jiang(cEJJ） in terms of appearance, smell and taste, but has no therapeutic effect.And participants need to return to the research center on time for relevant examinations according to the protocol requirements.
