Cajeput oil is a volatile oil obtained by steam distillation from the leaves of Melaleuca leucadendra. https://de.wikipedia.org/wiki/Cajeput%C3%B6l

„The majority of the oil is produced on the Indonesian island of Sulawesi. The name “cajeput” is derived from its Indonesian name, kayu putih (white wood).“ http://en.wikipedia.org/wiki/Cajuput_oil

„Commercial cajuput oil is mainly derived from M. cajuputi subsp.cajuputi. The oil of this taxon mostly, but not always, contains substantial amounts of 1,8-cineole (3–60%), and the sesquiterpene alcohols globulol (trace–9%), viridiflorol (trace–16%) and spathulenol (trace–30%). Other compounds present usually in significant quantities are limonene (trace–5%), ß-caryophyllene (trace–4%), humulene (trace–2%), viridiflorene (0.5–9%), α-terpineol (1–8%), a- and ß-selinene (each 0–3%) and caryophyllene oxide (trace–7%). This oil will hereafter be referred to as ‘type’ oil. The aromatic ether, cajeputol appears to be absent from the oil of this subspecies. Oil yield ranges from 0.4% to 1.2% (w/w%, fresh weight). The essential oil of M. cajuputi subsp. cumingiana is highly variable in character. The main components reported in oil from Indonesia, Malaysia, Thailand and Vietnam (non-or low-1,8-cineole forms) are γ-terpinene (0–19%), and terpinolene (0–22%)… The essential oils of M. cajuputi subsp.platyphylla occur in two chemotypes. Typically, the oils contain significant quantities of α-pinene (34–73%), with lesser amounts of 1,8-cineole (0.2–3%), γ-terpinene (trace–2%), p-cymene (trace–1%), terpinolene (trace–1%), ß-caryophyllene (2–14%), aromadendrene (1–9%), humulene (1–7%), viridiflorene (trace–3%), caryophyllene oxide (trace–2%), globulol (trace–6%), viridiflorol (trace–2%), spathulenol (trace–3%) with an absence of cajeputol.“

Cajeput oil is used in aromatherapy and as an antiseptic in nose drops.
