Condition analysis: Due to menstrual blood loss, especially menorrhagia, the main components of blood, such as plasma protein, iron, potassium, calcium and magnesium, will be lost during each menstrual period. Therefore, protein, minerals and blood-enriching food should be supplemented within 5 days after menstruation is clean1-. Choose foods that are both cosmetic and blood-nourishing, such as milk, eggs, pigeon eggs, quail eggs, beef, mutton, pig's trotters, Gordon Euryale seeds, spinach, longan, carrot apples, lychee meat, cherries, etc.
