The wood is close grained and very hard with the sap wood whitish to pale brown, but with handsome, dark reddish brown or golden brown heartwood. It works well and takes a fine finish and is most suitable for quality furniture. It is extremely durable and makes good fencing posts.
An infusion of fresh bark is believed to relieve colic. An infusion of the leaves has also been used as an eye lotion for both humans and animals, while a decoction of the leaves provides a gargle for sore throats.
The plants are browsed by stock, but the leaves are said to be astringent. Although rather bitter, the fruit is edible and widely sought after.
