Watermelon cream can be used during menstruation. Watermelon cream can mainly treat mouth ulcers, pharyngitis or sore throat, and will not affect menstruation itself, so watermelon cream can be used during menstruation to give the appropriate treatment. Menstruation is a normal physiological phenomenon for women, but it is also a special period, so the medication and diet during menstruation should be paid attention to, for example, the blood-boosting drugs should not be eaten. In addition, hormonal drugs are recommended to be used only under the guidance of a doctor, and cold foods are not allowed during menstruation, such as seafood, watermelon, pear, barley, winter melon and other foods that may have a corresponding effect on menstruation or cause dysmenorrhea if eaten.
