Brown sugar water is neither to be drunk before nor after menstruation, but rather during menstruation. It is recommended to drink a bowl of hot brown sugar water every day during menstruation. The main effect is to make the menstrual blood flow more smoothly and to reduce the discomfort in the lower abdomen caused by menstruation. In addition, brown sugar water also has the effect of replenishing blood, and can also reduce the fatigue during menstruation, so it is recommended to drink brown sugar water when menstruation. If you have diabetes, you should not drink it, and you should also pay attention to keeping warm during your menstrual period. In addition, you must not drink frozen drinks or eat food from the refrigerator immediately to avoid lower abdominal pain or prolonged menstruation.
