Other Uses

A small quantity of essential oil is obtained from the leaves. Total quantity of the oil, and its composition, can vary widely from plant to plant, but we have reports that the fresh leaves contain around 0.2 - 1.6% (1.5 - 1.5% dry weight) essential oil. The main components include pinene, 1,8-cineole (up to 68% in some reports), cymene, trans-pinocarveol, globulol and limonene[
