Tradition
Traditional ethnobotany

Native to the dry forests and plains of eastern Australia, Alstonia constricta — sometimes called "quinine bark" by settlers for its bitterness — was used by Aboriginal peoples and then by nineteenth-century Australian herbalists as a bitter tonic and febrifuge. Its gray, fissured bark, rich in alkaloids, holds a quiet but recognized place in the continent's traditional pharmacopoeia.

Traditional uses

Digestive

A bitter digestive tonic

The bark was traditionally used in small amounts to stimulate the appetite and support sluggish digestion, in the manner of the great bitter plants.

Fever & infections

Support during feverish states

Locally nicknamed "quinine bark," it was used as a substitute for cinchona to accompany bouts of fever, notably in colonial Australia.

Respiratory

Accompanying respiratory ailments

The bark decoction traditionally served to support the airways during catarrhal states or persistent coughing.

General tonic

A fortifier during convalescence

Used in small, repeated doses, the bark was reputed to restore strength after an illness or general weakening.

Precautions

Before you use it

A plant with active alkaloids (notably alstonine and reserpine-like compounds): never exceed the very low traditional doses, and seek the advice of a health professional before any use. Not advised during pregnancy and breastfeeding owing to a lack of safety data and the presence of potent alkaloids. Not suitable for children. Risk of interaction with cardiovascular or psychotropic treatments; to be avoided during ongoing medical treatment without prior medical advice.
