Bai zhu

Seven species of rhizomatous perennials belong to this genus, which is E Asian in distribution. All seven species are used in traditional Chinese medicine, the most important being A. macrocephala, which was first recorded in CE659 in the Tang Materia Medica. It is not common in the wild and is now grown on a large scale to satisfy demand. Botanical gardens in China are also researching the cultivation requirements of other species used similarly, such as A. lancea. In addition to its tonic properties, A. macrocephala is reputed to calm a restless fetus. Atractylodes chinensis is also widely used, mainly as a digestive tonic, and for glaucoma and night blindness.

Erect perennial with thick warty rhizomes, branched, woody-based stems, and divided, pointed, toothed leaves. Purple thistle-like flowers, 3.5cm (1¼in) across, are produced in summer followed by bristly seeds.
