SYDNEY - PennZone -- A large epidemiological study in the USA, conducted by Franklin Health Research Centre, conclusively rules out any purported links between Tea Tree Oil and breast development in young boys, a medical condition called gynecomastia.

BACKGROUND
Studies by Henley & Korach (2007), Diaz (2016), and Ramsey & Korach (2018) purported a causal link between Tea Tree Oil, Lavender Oil and endocrine disruption in children. While studies were widely refuted, without solid epidemiological evidence, the sensationalist headlines remained.

RESULTS
The epidemiological evidence is now in hand, published in the International Journal of Pediatrics and Adolescent Medicine, by Hawkins et al., titled "Prevalence of Endocrine Disorders Among Children Exposed to Lavender Essential Oil and Tea Tree Essential Oils".

"This study provides evidence that lavender essential oil and tea tree essential oil are safe ingredients in formulations for personal care products used on children."

The authors concluded:

"The proposed links between these ingredients and endocrine disruption cannot be substantiated in epidemiological studies."

The cross-sectional, prospective study was designed to identify the lifetime prevalence of endocrine disruption among children exposed to Lavender and Tea Tree essential oils, compared with the general population. A study cohort of 556 children, aged 2 to 15 years old was enrolled to yield sufficient statistical power.

"This is great news as it once and for all clears up misinformation about Australian Tea Tree Oil, allowing parents to feel comfortable using products that contain this highly efficacious natural ingredient." Tony Larkman – CEO, ATTIA Ltd
