Duration depends on the condition: ① mild menstrual disorders: 1–2 months, ② chronic dysmenorrhea/PMS: 2–3 months, ③ infertility/menopause: 3–6 months, ④ postpartum care: 1–3 months, ⑤ recurrent cystitis/vaginitis: 1–2 months. Treatment effects are typically seen within the first 1–2 menstrual cycles. After symptom improvement, maintenance for 1 cycle prevents recurrence. Constitution-based prescription adjustments may be made monthly.
