Scented oils linked to male breast growth
THE lavender and tea tree oils found in some soaps, shampoos, hair gels and body lotions can produce enlarged breasts in boys, researchers reported today.
These plant oils were linked to abnormal breast development in three boys, which was reversed when they stopped using them, Dr Clifford Bloch of Pediatric Endocrine Associates in Greenwood Village, Colorado, and colleagues reported.
They said their study, published in today's issue of the New England Journal of Medicine, suggested these oils could act in ways similar to the hormone estrogen.
