Three young boys grew breast tissue after exposure to lotions and shampoos containing lavender or tea tree oil, researchers say.Well-meaning hippies: is there any force of nature more dangerous?
It is not uncommon for boys to develop breast tissue during puberty or just after, but the boys affected by the plant oils were aged four, seven and 10.
The natural oils may be “gender-bending” chemicals mimicking effects of the female hormone, oestrogen, the findings suggest. The boys were otherwise normal, and lost the breast tissue within months of discontinuing use of the products.
Researchers who identified the oils as the cause of the abnormalities in the three pre-pubertal boys have warned parents and doctors to beware of the effects of any toiletry products containing the oils.
