1. Generally speaking, you can drink red bean and barley tea during menstruation. Red bean and barley tea has the function of eliminating moisture in human body, and drinking a small amount will not affect menstruation. However, during menstruation, you can't drink too much red bean barley tea, because barley is a cold food, and drinking it in large quantities may lead to increased cold in the body and blood stasis, thus causing dysmenorrhea.

2. In addition, women should pay attention to avoid eating cold food during menstruation, pay more attention to rest, keep the abdomen warm, avoid catching a cold, and pay attention to personal hygiene. Don't share the same room during menstruation to avoid infection.
