The presence of blood clots during menstruation is not a detoxification phenomenon, but an abnormal one. Under normal circumstances, women’s menstruation is dark red blood without blood clots, but if there is a blood clot, the cause should be identified and corresponding treatment should be taken. It is possible that the blood clots are caused by the high volume of menstruation and the blood cannot be discharged in time to form clots. If a woman has a blood clot during her menstrual period and it is accompanied by dysmenorrhea, it is caused by cold in the uterus and requires warmth in the abdomen. The discharge of blood clots may also be a manifestation of Qi stagnation and blood stasis, when the patient should learn to self-regulate their emotions and maintain a good state of mind.
