Kun Ning Oral Liquid may generally lead to stopping bleeding after taking it for 3-4 days. Kun Ning Oral Liquid contains Chinese herbal ingredients such as Yi Mu Cao, Angelica Sinensis and Dang Shen. It has the effect of activating blood circulation, stopping bleeding and regulating menstruation, and is used for the treatment of increased menstrual flow and prolonged menstruation caused by stagnation of blood and Qi. However, if a woman causes intrauterine bleeding, it is caused by unstable secretion of hormone levels, such as late withdrawal of progesterone, imbalance of estrogen secretion or suffering from endometrial polyps and uterine fibroids. Oral administration of Quinine oral solution alone is not effective. It should be effective to give estrogen and progesterone for cyclic treatment so that the endometrium can undergo cyclic exfoliation. For uterine fibroids that do not work well by hemostatic drugs, surgery should also be given in time for treatment.
