Respiratory Relief, accounting for roughly 45 % of sales, targets conditions such as cough, phlegm, and bronchial irritation, driving the largest share of formulation development and clinical validation. Digestive Regulation, representing about 30 % of the market, addresses dyspepsia, gastritis, and intestinal inflammation, influencing raw‑material sourcing toward mucosal‑protective herbs. Dermatological Care, with an estimated 15 % share, is applied to skin eruptions and eczema, prompting niche packaging for topical administration.
