Product Description: Attached to a short woody twig, the dried buds are ovate in shape, like the end of an artist's paint brush. They are 1–4 cm long, and 0.7–2 cm in diameter. The outer layer comprises 2 bracts in 2 layers, whose outer surface is covered with soft, long whitish brown hairs 5 mm in length, and whose inner surface is brown and smooth. The bracts can be removed to reveal 3 calyces, and 6–12 tightly wrapped brown petals, amidst which are numerous brownish yellow stamens and a brown pistil. The buds are brittle and break easily.
Quality: Best are dry unopened buds that are green in color and have no stalks.
Product Area: Hénán, Sìchuān, ānhuī, Shǎnxī (Shaanxi), and Húběi.
Etymology: The name xīn yí 辛夷 is interpreted as the homophone 辛荑, acrid bud,
reflecting both the choice of immature flower and its acrid quality.
