This rhizome is cylindrical and branching. It is 5–12 cm in length and 1–2 cm in diameter. The exterior surface is a reddish-brown, with longitudinal wrinkles, and leaf scars forming pale wavy markings about 5 mm apart, encircling the rhizome. At the lower end are scars left by the fine roots. This rhizome is hard and breaks with difficulty to reveal an uneven fibrous orange-brown fracture. The decocting pieces are oblique or longitudinal slices 1–2 mm thick and irregular in shape. The cut edge reveals diffuse vascular bundles. The inner layers of skin and the central core of the wood are slightly darker in color.
