Women should not eat persimmons during menstruation because their digestive and immune functions are reduced during menstruation, so they should not eat foods or fruits that are too cold, spicy or salty. If a woman eats a lot of persimmons during her menstrual cycle, it can cause stagnation of menstrual blood in the body, poor discharge, and possibly dysmenorrhea. In addition, because women lose a lot of blood during menstruation, they need to replenish iron in time, and persimmons contain ellagic acid, which can easily bind with iron and prevent the body from absorbing it. This shows that female patients should not eat persimmons during menstruation, and if they accidentally eat a lot of persimmons, they may prolong their periods and also experience pain in the abdomen.
