| The essential oil, obtained from the foliage and terminal branchlets by steam distillation, is used as antimicrobial and expectorant. [[http://en.wikipedia.org/wiki/Tea_tree_oil]] \\ | "As indicated by the title of the ISO standard, tea tree oil is rich in terpinen-4-ol, typically in the range of 35-42%. 1:8-cineole has also been noted as an important constituent, even though it rarely exceeds 5% in commercial oil. In the early days, 1:8-cineole was noted in order to distinguish the various chemotypes of tea tree oil available: low cineole (2-10%), high cineole (20-40%) and very high cineole (60%+). During the 1980s boom time, however, the cineole content of tea tree oil became an indicator of quality - the lower the better. Various reasons were given as to why cineole was supposedly detrimental to the oil, such as it being a skin irritant. This was despite much published information that cineole was not a skin irritant, including one report that named nearly all the components of tea tree oil other than cineole as being potential skin irritants. Slowly, the industry realised that terpinen-4-ol was the main indicator of antimicrobial activity, or at least up to levels of 40%. Interestingly, none of the individual components of tea tree oil, including |
| | terpinen-4-ol, are as widely active as the whole oil." \\ |
| | A typical gas chromatographic profile for Australian tea tree oil shows as components: α-pinene (1-6%), sabinene (trace-3.5%), α-terpinene (5-13%), limonene (0.5-4%), ρ-cymene (0.5-8%), 1,8-cineole (0-15%), γ-terpinene (10-28%), terpinolene (1.5-5%), terpinen-4-ol (30-48%), α-terpineol (1.5-8%), aromadendrene (trace-3%), ledene (trace-3%), δ-cadinene (trace-3%), globulol (trace-1%), viridiflorol (trace-1%). \\ |

| The essential oil (Melaleucae aetheroleum), obtained from the leaves by steam distillation, is widely used in ointments and creams to treat insect bites,wounds, abrasions, acne, skin infections, fungal infections (including athlete's foot and trush). "The monoterpenes interact with biomembranes and mebrane proteins, tus explaining the observed antibacterial, antifungal and antiviral acivities. A few clinical studies have shown positive results in the treatment of acne and fungal infections." \\ | The essential oil (Melaleucae aetheroleum), obtained from the leaves by steam distillation, is widely used in ointments and creams to treat insect bites,wounds, abrasions, acne, skin infections, fungal infections (including athlete's foot and trush).
