The primary mechanism for a painful period is blood stasis. When the blood flow from the uterus is blocked or restricted by endometriosis, stenosis of the cervix, or abnormal uterine position, etc., it stimulates the uterus, thereby causing pain. This formula has an anti-coagulating effect, which decreases blood viscosity and thus improves blood flow. It inhibits and synchronizes the contraction of uterine muscles. In a laboratory test, it had a significant, antagonistic blocking effect on PGF2ƒÑƒn and pituitrin-induced intense contractions of isolated uteri. Clinically, its effective rate for membranous endometriosis and primary dysmenorrhea is around 87%. Among them, approximately 77% of cases do not have recurrence within a 3-19 month period. ACTIONS: Removes blood stasis, synchronizes uterine contraction and facilitates blood flow. RECOMMENDATIONS: Endometriosis or abdominal cramping during period. SUGGESTED USE: Take 3-4 pills three times daily with water as a food supplement, one week before period through the 4th day of the period. Repeat for at least 3 menstrual cycles.
