The art of healing: five medicinal plants used by Aboriginal Australians

People have lived in Australia for at least 65,000 years. In all those generations the land provided original Australians with everything they needed for a healthy life.

At least half the food eaten by the first Australians came from plants, and it was the task of women to collect them. Fruits, seeds and greens were seasonal, but roots could usually be dug up all year round, because the earth acted as a natural storage cupboard.

The particular plants eaten or used as medicine varied in different parts of Australia. In Arnhem Land, North Queensland and the Kimberley, many tropical trees bear fruits and seeds, such as native figs (Ficus spp.), lilly-pillies (Acmena, Eugenia and Syzygium spp.) and macadamia nuts.

In Central Australia, where water is scarce, plants are spread thinly over the land. Here the people relied more on the seeds of native grasses and wattles such as mulga (Acacia aneura), wiry wattle (Acacia coriacea) and even the coolabah tree (Eucalyptus microtheca).

In the southern parts of Australia, roots (applying that word to all the underground parts of a plant) were the most important foods.

In terms of medicines, many different parts of plants were used. Native mints (Mentha spp.) were remedies for coughs and colds, while the gum from gum trees, which is rich in tannin, was used for burns. The green plum (Buchanania obovata) is enormously rich in vitamin C.

Here are five other plants that have medicinal uses:

1. Kangaroo apple (Solanum aviculare or Solanum laciniatum)

This is a great example of a food source and medicinal plant for many Victorian Aboriginal clan groups. This shrub varies in height. Its leaves resemble a kangaroo’s paw and it produces purple flowers.

The early fruits that form are at first yellow or green and highly poisonous, but can be eaten when they are at their ripest, turning a blood-orange colour. The fruit contains high levels of the alkaloid solanine, which can be infused from the leaves with hot water to create steroids.

Also known as bush apple, it has been farmed in several parts of the world to produce and manufacture oral contraceptives, using extracts from the young leaves and green fruits.

2. Wattles (Acacia spp.)

Australia has more than 1000 wattle species. The gum of some species (golden, silver and black wattles) was an important food as well as a useful cement. The seeds of other species are high in protein and carbohydrate and in arid areas were eaten both green and dry.

Wattle blossom was hung in people’s huts to promote sleep. In Victoria, the bark of blackwood (Acacia melanoxylon) was infused and used to bathe rheumatic joints, or ingested as a mild sedative for rheumatism or indigestion.

3. Old man’s weed (Centipeda cunninghamii)

Commonly found along the Murray River, as well as in other low-lying, swampy habitats, this plant is useful for treating many complaints, including eye infections, tuberculosis and skin complaints. It is administered as an extract in water, or sometimes rubbed onto the skin.

It’s usually used for colds and coughs and chest infections, but, being a natural restorative plant, it can help strengthen the immune system and mobility.

4. Drooping she-oak (Allocasuarina verticillata)

In Victoria, mature cones from this tree were ground up and applied to sores to treat rheumatism. Extracts from the bark and wood can also be used as a general medicine.

5. Hop bush (Dodonaea viscosa)

This plant grows across Australia. In Queensland the juice of the root was applied for toothache and cuts.

The chewed leaf and juice were put on stonefish and stingray stings and bound up for four or five days.
