Exposure to lavender essential oil may be linked to normal breast growth in girls according to a new study published in the Journal of Clinical Endocrinology & Metabolism.
This is the first study to report abnormal breast growth in adolescents in relation to lavender exposure although previous studies had associated breast growth in male boys with the use of lavender-containing fragrances.
According to the experiments conducted by the researchers behind this study, breast growth in both girls and boys was interrupted after the interruption of the use of perfumed products containing lavender. The researchers also determined that some components in essential oils may block the testosterone of boys or mimic estrogen in girls and this, according to the researchers, could explain the observed breast growth in the cases they analyzed.
The study was conducted by J. Tyler Ramsey, a second-year medical student at Campbell University as well as a researcher at the National Institute of Environmental Health Sciences (NIEHS).
Ramsey himself analyzes the results: “The public should be aware of these results and consider all the tests before deciding when to use essential oils. It is also important that physicians are aware that lavender and tea tree oils contain tea endocrine-disrupting chemicals and should be considered in assessing premature breast development in girls and boys and in children swelling of breast tissue in adult men.”
