Do not drink dampness-removing tea during menstruation. During the menstrual period, women experience heavy bleeding and physical weakness. Dampness-removing tea contains large amounts of heat-clearing ingredients and is considered a cold beverage, which may easily lead to increased menstrual flow and symptoms such as dysmenorrhea; therefore, it should be avoided if possible. Furthermore, due to heavy blood loss during menstruation, blood viscosity increases and iron ion levels rise in the body. Dampness-removing tea contains high levels of tannic acid, which can readily form ferrous tannate, potentially causing iron-deficiency anemia in women.
