Menopause treatment duration depends on severity: ① mild symptoms (occasional hot flashes): 3–6 months, ② moderate (regular symptoms with sleep disturbance): 6–12 months, ③ severe (severe hot flashes, depression, insomnia): 1–2 years, ④ premature menopause (under 45): longer term care. Significant improvement often felt within 1–2 months. Maintenance herbal dose during seasonal transitions (spring/autumn) helps prevent recurrence.
