Moutan Bark

Dried peony bark is mostly in the form of tubular or semi-tubular thin slices, 5–20 cm long, 0.5–1.2 cm in diameter, and 1–4 mm thick.

The outer surface is grayish-brown or yellowish-brown, with numerous transverse lenticel-like protrusions and fine root scars; the area where the cork has fallen off appears pinkish.
