Description:This spectacular, and unexpectedly hardy shrub, bears dense spikes of flamboyant red bottle-brush flowers that appear in late spring and early summer. Narrow, sharply pointed leaves adorn this dazzling shrub that is possibly the hardiest of all bottle brushes.

The essential oil from the leaves of Callistemon rigidus R. Br., a traditional Chinese medicinal plant, has been analyzed and found to contain thirteen compounds. The oil was predominantly 1, 8-cineole (89.9%).
From stem bark of Callistemon rigidus (Myrtaceae), piceatannol and scirpusin B were isolated as components that exhibit inhibitory effects on alpha-amylase activity in isolated mouse plasma. In particular, scirpusin B also inhibited alpha-amylase in mouse gastrointestinal tract. Thus, we expect the depressive effect on the elevation of postprandial blood glucose may be a new medicinal use of this compound as well as the plant itself.
