"Prepubertal Gynecomastia Linked to Lavender and Tea Tree Oils"
http://www.nejm.org/doi/full/10.1056/NE ... #t=articleWe investigated possible causes of gynecomastia in three prepubertal boys who were otherwise healthy and had normal serum concentrations of endogenous steroids. In all three boys, gynecomastia coincided with the topical application of products that contained lavender and tea tree oils. Gynecomastia resolved in each patient shortly after the use of products containing these oils was discontinued. Furthermore, studies in human cell lines indicated that the two oils had estrogenic and antiandrogenic activities. We conclude that repeated topical exposure to lavender and tea tree oils probably caused prepubertal gynecomastia in these boys.
Nur drei Fälle, dafür aber nachweisbare östrogenartige und anti-androgene Reaktionen auf Zellebene. Die Details stehen im Paper.
- Hormonlevel im Blut alle normal
- anscheinend nur Brustwachstum
- reversibel nach Absetzen
