If you have a large blood clot after delivery, it is important to look carefully at the clot to see if there is any flesh-like tissue in it. If there is flesh-like tissue, it is caused by incomplete fetal membranes. When the fetal membranes are incomplete, they may accumulate in the uterine cavity and cause localized bleeding, resulting in a large clot that is expelled from the body along with the fetal membranes. When the uterus is not contracting properly, the blood in the uterine cavity is not discharged in time, so it accumulates in the uterine cavity and forms a blood clot. When it is eliminated, clots are clinically found to be relatively large. In this case, it is recommended that oral treatment with motherwort capsules or new biochemical capsules be given to promote uterine contraction.
