Medicinal Uses:
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.

Other Uses:
Architectural, city courtyard garden, coastal/seaside suitable, container plant, cottage informal garden, drought resistant, flowering shrub, low maintenance, mediterranean, mixed shrub border and fragrance.
