In a Nutshell:
* Dodonaea viscosa is a species of flowering plant in the soapberry family, Sapindaceae, that has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia.
* D. viscosa is a shrub growing to 1–3 m (3.3–9.8 ft) tall, rarely a small tree to 9 m (30 ft) tall.
* It is believed that D. viscosa flowers lack petals during evolution to increase exposure to the wind.
* The fruit is a capsule 1.5 cm (0.59 in) broad, red ripening brown, with two to four wings.
* The wood is extremely tough and durable. In New Zealand, where it is the heaviest of any native wood, the Māori have traditionally used it for making weapons, carved walking staves, axe-handles, and weights on drill shafts.
* Native Hawaiians made pou (house posts), laʻau melomelo (fishing lures), and ʻōʻō (digging sticks) from ʻaʻaliʻiwood and a red dye from the fruit.
* Dodonaea viscosa can be grown from seeds. However, pre-treatment of the seed in very hot water may be needed. more...
* The leaves are anodyne, astringent, diaphoretic, febrifuge (the var. angustissima is normally used), odontalgic and vulnerary. They are applied internally in the treatment of fevers. Externally, they are used to treat toothache, sore throats, wounds, skin rashes and stings. The leaves are apparently effective in the treatment of toothache if they are chewed without swallowing the juice. The bark is employed in astringent baths and poultices.
* Plants are very tolerant of pruning and make a good hedging plant for windy sites. more...
