About Acacia confusa Merr.
Scientific name: Acacia confusa Merr.
Introduction Acacia confusa is a perennial tree native to Southeast Asia. Its common names include ayangile, small Philippine acacia, Formosa acacia (Taiwan acacia), Philippine Wattle, and Formosan koa. It reaches a maximum height of 15 m. This tree has become very widespread across many tropical Pacific regions, including Hawaii, where it is classified as an invasive species.
Uses The wood of Acacia confusa has a density of approximately 0.75 g/cm³. Historically in Taiwan, this wood was used to make support beams for underground mines. Acacia confusa wood is difficult to work with, so in traditional Taiwanese practice it was most often burned as firewood or processed into charcoal. In later decades, the wood was exported from Taiwan to China to be manufactured into wood flooring intended for the American market. At the peak of this trade, Taiwan exported more than 1,000 containers of Taiwan acacia to China annually. More recently, the wood has been used domestically in Taiwan to produce high-value wood products such as musical instruments, furniture, and bathtubs. It is also still processed into charcoal for household use. The plant is used in traditional medicine and is sold in herbal medicine shops in Taiwan, though no clinical studies have been conducted to confirm its medicinal effectiveness.
