Clinical Summary
Maroon bush is a plant native to Australia where it is used in traditional medicine for colds, stomach ailments, and as a diuretic by the Aboriginal people. Flavonoids, tannins, alkaloids, anthraquinones, polysteroids, saponins, cardiac glycosides and phenolic compounds are among the constituents found in maroon bush (2)(3).
The plant extracts demonstrated antibacterial and antiviral properties in vitro without any toxic effects (1)(2). Infusions made from the leaves and branches are thought to have anticancer effects, leading to heightened interest in this plant as an alternative cancer treatment. But human studies have yet to be conducted.
