Most of the drugs that activate blood circulation and remove blood stasis to contract the uterus can be taken orally if there is some residual tissue in the uterine cavity, or some fluid left in the uterine cavity after abortion, or after diagnostic scraping surgery, due to uneven shedding of the endothelial lining in the uterine cavity, and there is placenta residue after delivery. Generally, it can be divided into New Biochemistry Granules, including Hematopoietic Capsules, including Motherwort Combination, which can be taken orally at this time. If there is a lot of residual blood, you can also take mifepristone 25mg orally once a day for 7 days. However, if there is only a small amount of blood accumulation, it is better to use proprietary medication. After taking the oral medication, try to move around as much as possible, which will help the uterus to contract and help to expel the residual tissues and blood from the uterine cavity. Absolute bed rest is not recommended because it can affect the contraction of the uterus.
