Heavy menstrual flow is usually not taken with motherwort, because motherwort itself has the effect of nourishing and invigorating the blood, which may lead to more bleeding. However, there is an exception, if the heavy menstrual flow is accompanied by large blood clots, or similar to flesh film-like, it is actually shed endometrium. In this special case, motherwort can be taken to nourish the blood, invigorate the blood, dispel stasis and produce new blood, and only after the stasis is cleared, the blood can return to the menstruation, which will help to eliminate stasis and stop bleeding, so it must depend on the bleeding situation. For a normal menstrual cycle, the amount of menstruation is between 5-80mL. If it exceeds 80mL, it suggests that it is a heavy menstruation, and if it is not accompanied by blood clots, stop using motherwort. If there is blood clot or a lot of blood clots, you can add motherwort appropriately, it can play a role in removing blood stasis and stopping bleeding.
