The flowers and seeds of the plant are used in the making of leis. The leaves are burned as an insect/mosquito repellent. Oils from the leaves show considerable mosquito repellent activity. The active principle has been identified as rotundinal, a cycloterpene aldehyde. The plant shows considerable potential as a botanical pesticide that may be applied both indoors and outdoors. The wood is used in light construction and for tools and axe handles. The wood is used for fuel. The plant is often used as a hedge, especially in Asia, although it may trigger various allergic reactions (sneezing, respiratory problems, dizziness, headache, nausea) to people trimming or pruning such hedges. The plant has been used to control erosion on sand dunes, which it does well within its native range. However, its ability to escape from cultivation, plus its negative effect upon some wildlife, makes it unsuitable for this purpose in other areas. The plant makes an excellent ground cover.
