Treatment duration: ① mild cases (no underlying issue): 1–2 months, ② chronic urinary issues with BPH: 3–6 months, ③ post-prostate-surgery: 6–12 months, ④ overactive bladder: 2–3 months. Many feel improvement within 4 weeks. Maintenance herbs after symptom resolution prevent recurrence. Combined with lifestyle (limit caffeine, evening fluids) for best results.
