If you have had a baby and the dew is not clean for more than 60 days, and if the dew persists and is discharged intermittently, you should first consider that the contraction of the uterus is not good or that there is residual material in the uterine cavity. If the contraction of the uterus is not good, but the amount of residue is not large, you can take conservative treatment, oral motherwort granules or new biochemical granules. This medication can promote uterine contraction, which can activate blood circulation, remove blood stasis and dredge meridians, and promote the discharge of residual material in the uterine cavity. If the quality of residue is high, timely treatment of uterine evacuation is needed. This phenomenon can be eliminated only after the uterine cavity is cleared manually and the residual material in the uterine cavity is removed and can be well improved.
