From a product‑type perspective, the market is split among three delivery formats: powder, capsule, and liquid. Powder formulations, which include raw‑herb blends and granulated extracts, capture about 45 % of volume due to lower manufacturing costs and strong preference among traditional‑medicine practitioners for decoction preparation. Capsule formats, comprising standardized extracts and patented blends, hold roughly 35 % of the market; they offer dosage precision and enhanced patient compliance, factors that have accelerated adoption in urban pharmacies. Liquid preparations, encompassing decoctions and concentrated tinctures, account for the remaining 20 % and are favored in clinical settings where rapid absorption is required. The relative contributions of these types reflect both supply‑chain efficiencies and end‑user preferences, shaping the overall market taxonomy for Tongqiao Erlong Wan.
