Application‑based Qijudihuang Oral Liquid segmentation reveals three dominant use‑cases: Respiratory disorder management, Immune modulation, and Chronic fatigue mitigation. The respiratory disorder category, encompassing asthma, bronchitis, and post‑viral cough, commands the largest slice of demand, representing about 45% of sales, as clinicians prescribe the liquid for its mucolytic and anti‑inflammatory properties. Immune modulation, which includes prophylactic use in immunocompromised patients and adjunct therapy for viral infections, contributes roughly 35% of the market, reflecting heightened awareness of immune health in the post‑pandemic era. The chronic fatigue segment, targeting patients with prolonged malaise and post‑exertional fatigue, accounts for the remaining 20%, supported by emerging evidence of the formula’s adaptogenic effects. These application sub‑segments collectively determine product positioning, pricing elasticity, and R&D focus, thereby influencing the overall market valuation.
