Folk medicinal uses

This tree, a native of Eastern Asia, is found occasionally in Jamaica in cultivation. The crushed leaves with proof rum are reported to make an excellent cooling application for headache. All parts of the tree yield an essential oil and some varieties also give solid camphor. It is primarily stimulant and diaphoretic and secondarily sedative and anodyne.
