What is tea tree oil?

Tea tree oil is defined by the International Standard ISO 4730 (“Oil of Melaleuca, Terpinen-4-ol type”), which specifies levels of 15 components which are needed to define the oil as “tea tree oil.” The oil is extracted from the leaves of the tea tree via steam distillation. This essential oil possesses a sharp camphoraceous odor followed by a menthol-like cooling sensation. Most commonly an ingredient in topical products, it is used at a concentration of 5% to 10%. The oil has been described as having a fresh, camphor-like smell.

Tea tree oils have six types, oils with different chemical compositions. These include a terpinen-4-ol type, a terpinolene type, and four 1,8-cineole types. These various oil types contain over 98 compounds, with terpinen-4-ol the major component responsible for antimicrobial and anti-inflammatory properties.[9] A second component 1,8-cineole, is likely responsible for most allergies in TTO products. Adverse reactions to TTO diminish with minimization of 1,8-cineole content. In commercial production, TTO is prepared as a terpinen-4-ol type. (Wikipedia)

Here is some great research on the medicinal qualities of tea tree oil:

2004 Study: Herbal medicines for treatment of fungal infections: a systematic review of controlled clinical trials. “Tea tree oil preparations were tested in four randomized clinical trials and some positive outcomes were attributed to the intervention in all trials. Solanum species (two trials) and oil of bitter orange preparations (one trial) were compared with conventional treatments. In all cases encouraging results were reported. There are few controlled clinical trials of herbal antifungal medicines.”(1)

A 2004 NCCIH-funded review examined the ability of tea tree oil to kill bacteria and found that in vitro (in a test tube) studies may provide some preliminary evidence for the use of tea tree oil as an adjunctive (additional) treatment for wounds involving difficult-to-treat bacterial infections such as methicillin-resistant Staphylococcus aureus (MRSA).(2)

In a study in 2007 by by the National Institutes of Health, a randomized double-blind clinical trial performed in 60 patients with mild to moderate acne vulgaris. The people were randomly divided into two groups and were treated with tea tree oil gel (n=30) or placebo (n=30). They were followed every 15 days for a period of 45 days. Response to treatment was evaluated by the total acne lesions counting (TLC) and acne severity index (ASI). The data was analyzed statistically using t-test and by SPSS program.(3)

A 2011 study in PubMed: Tea tree oil might combat melanoma– “In this study we present new data from experiments focused on the antitumor activity of tea tree oil (TTO), an essential oil distilled from Melaleuca alternifolia. TTO proved to be capable of inhibiting the growth of melanoma cells and of overcoming multidrug resistance (MDR), as we reported in our previous study. Moreover, the survival role of the MDR-marker P-glycoprotein appears to be involved in the mechanism of invasion of melanoma cells. The results reported herein indicate that TTO and its main active component, terpinen-4-ol, can also interfere with the migration and invasion processes of drug-sensitive and drug-resistant melanoma cells. PMID:20560116.”(4)

A 2013 study on the effect of tea tree oil (Melaleuca alternifolia) on wound healing using a dressing model.– “Numerous studies have shown the promising antibacterial effects of Melaleuca alternifolia, or tea tree essential oil. The study detailed here replicates in humans a 2004 in vitro study that used a dressing model over Petri dishes to determine the antimicrobial effects of the fumes of tea tree essential oil. The current study used the same dressing model with patients who had wounds infected with Staphylococcus aureus.

Ten participants volunteered for the quasi-experimental study, and four of the 10 were used as matched participants to compare wound healing times between conventional treatment alone and conventional treatment plus fumes of tea tree essential oil. The results demonstrated decreased healing time in all but one of the participants treated with tea tree oil. The differences between the matched participants were striking. The results of this small investigational study indicate that additional study is warranted.” PMID:23848210 (5)

Where does tea tree oil come from?

Tea Tree, a name applied not only to the Thea bushes (see Tea), but to various species of Leptospermum and Melaleuca — myrtaceous shrubs found from China to Australia, New Zealand and Tasmania. The teatree forms a common and almost impenetrable scrub of Victoria, in moist situations. It is a shrub of varying height and dark-green color, the branches bushy and growing perpendicularly, the leaves resembling the needles of a fir.

The stems are straight, the wood hard and valuable for many bush purposes. Several of the tea-trees belonging to the genus Melaleuca furnish the aromatic, pungent cajeput oil (see Cajbput) of commerce. It is especially obtained from M. leucadendron, a tree reaching 30 feet in height, with terminal spikes of white flowers, and elliptical to lanceolate leaves, from which the oil is distilled. It has a crooked trunk, papery bark, employed in packing, and yields a wood which is white, close-grained, hard and durable, even under the ground. M. squarrosa or swamp tea-tree has a thin bark, and the thin, spongy cortex of M. axillaris can be used as a filter or blotting paper.

The New Zealand tea-tree or tea-scrub is Leptospermum scoparium, a heather or juniper-like shrub with leathery foliage, like needles, and many small white blossoms. The common name is said to have been derived from the use of the foliage of this shrub and that of L. laiiigerum by Captain Cook for tea, but the native name of the former is “ti.B The white tea-tree is L. ericoides, of New Zealand. Other tea-trees are the bottle-green Kunzea corifolia, and the broad-leaved Callistemon salignus, both of Australia and Tasmania; the Ceylon, Elwodendron glaucum, and the red scrub tea, Rhodamnia trinervia, several of which are myrtaceous and have hard, heavy close-grained wood.(6)
