Range of Acacia confusa

Acacia confusa is a perennial tree native to South-East Asia. Some common names for it are Acacia Petit Feuille, Small Philippine Acacia, Formosa Acacia (Taiwan Acacia) and Formosan Koa. It grows to a height of 15 m. The tree has become very common in many tropical Pacific areas, including Hawaii, where the species is considered invasive.[3]


Its uses include chemical products, environmental management and food and drink. The bark may be ground into a powder and saturated into water to create a tea, or may be spread onto various foods as a spice and taste enhancer. The wood has a density of about 0.75 g/cm³.[4] In Taiwan, its wood is used to make support beams for underground mines. The wood is also converted to charcoal for family use. The plant is used in traditional medicine[5] and is available from herbal medicine shops (草藥店) in Taiwan, but there has been no clinical study to support its effectiveness. It is also frequently used as a durable flooring material.
