TEA TREE OIL
EFFICACY + SAFETY
The Proven Tea Tree Oil.
The most evidenced tea tree oil in the world.
100% Pure Australian
Tea Tree Oil.
Nearly all research has been conducted on 100% pure
Australian tea tree oil so therapeutic benefits are proven only
on this product.
Efficacy.
100% pure Australian tea tree oil is underpinned by its effectiveness in laboratory studies and human clinical trials to address a long list of health issues, as well as its use in personal care applications.
“Contemporary data clearly show that the broad-spectrum antimicrobial activity of tea tree oil includes antibacterial, antifungal, antiviral and anti-protozoal activity.” ^

Antibacterial.
Well-established for its broad spectrum (Gram positive and Gram negative)
antibacterial activity, including methicillin-resistant Streptococcus aureus (MRSA).*º

Antifungal.
Several yeasts are susceptible to tea tree oil, including yeasts from the genera
Candida, Malassezia and Trichosporon families.^

Anti-inflammatory.
Tea tree oil can inhibit the production of several inflammatory mediators (such as
interleukins) and so may reduce the inflammatory response.^

Anti-viral.
Tea tree oil may act against viruses in several ways, including lethal effects directly
on virus particles.^

Safety.
The safety of 100% pure Australian tea tree oil as a consumer product is well
documented.
In fact, all oil used in safety studies presented to REACH and the SCCS for tea
tree oil use in the European Union were carried out on Australian tea tree oil,
as are the literature reports used in the European Monograph.
“Most TTO is used topically. Anecdotal evidence from almost 80 years of use
suggests that topical use is safe, and that adverse events are minor and occasional.” ^

Oral Toxicity.
Tea tree oil can be toxic if ingested, and tea tree is categorised as a Schedule 6 poison in
Australia. The European Union is proposing classification changes, and ATTIA welcomes those
related to oral toxicity.
To this end, neat tea tree oil should be labelled that it must be kept out of the reach of children,
packaged with a childproof cap, and labelled “not to be taken internally”.^
If these safety features are not present on a consumer product, then you should not purchase
it.

Irritant Skin Reactions.
Irritant skin reactions are often dependent on the concentration of tea tree oil, how
it has been stored, and if the product has been kept beyond its expiry date.
Newly distilled tea tree oil has a relatively low sensitising capacity whereas
degraded oil that has been exposed to light, oxygen, warmth and moisture could
be a moderate-to-strong sensitiser.^
Contact allergy is rare but can also occur in some individuals.^
It’s important to store your oil correctly by ensuring it has been tightly capped and
not exposed to light and fluctuating heat conditions.

‘The evidence base for 100% pure Australian tea tree oil’s efficacy
and safety is unmatched.’
