When should I take Wujibi Fengwan (Black Chicken and White Phoenix Pill)?

For women with irregular menstruation, the timing of taking Wuji Baifeng Pills should be flexibly adjusted according to individual menstrual cycles and physical conditions. Generally, treatment may start on the 5th day after menstruation ends, or on the 7th to 8th day, and continue until just before the next menstrual period begins, which can help regulate the menstrual cycle. If premenstrual syndrome symptoms are significant, treatment may also begin 7 to 10 days before the expected onset of menstruation and continue until the early phase of the menstrual period. However, specific administration timing and duration of treatment should be determined under a physician's guidance and according to medical advice. Additionally, maintaining healthy lifestyle habits and a positive mental state is also important for improving menstrual irregularities.
