The answer is yes, blood-boosting drugs can significantly increase the amount of menstruation and prolong the duration of menstruation if used during menstruation, and sometimes lead to excessive menstrual bleeding and bleeding anemia and other symptoms, so blood-boosting drugs should be avoided during menstruation. The so-called blood-boosting drugs generally refer to the blood circulation, promote blood flow, dissipate bruises, also known as the blood-boosting drugs. The main function of these herbs in clinical practice is to dissolve the blood clots and promote blood circulation, which has a significant effect on the old blood accumulation formed by some bruises and injuries. In addition to invigorating the blood and promoting menstruation, they can also break the blood, abort fetuses and induce labor, so they are contraindicated or used with caution for women with excessive menstruation or pregnant women. At the same time, blood-activating drugs have the effect of significantly improving hemodynamics, dilating peripheral blood vessels, increasing the permeability of blood flow and capillary permeability, aggravating swelling and reducing inflammatory exudation, and improving microcirculation. Therefore, during menstruation, if too many blood-activating drugs are used, or if they are used inappropriately, the effects on menstruation are self-evident. On the one hand, it increases the amount of menstrual bleeding, and at the same time, it may lead to serious postmenstrual bleeding causing danger, so the blood-activating drugs should be used with caution or prohibited during the menstrual period.
