~cause prepubertal gynaecomastia
well this is interesting!
I wonder what prolonged mild exposure will do to the male hormonal profile over and during purberty?
Another reason for soyboy-ness?
Many people i know have some sort of lavender or tea tree product at home - I’ve got 3different types of TTshampoo in the shower alcove right now!
In laboratory tests, scientists at the US National Institute of Environmental Health Sciences (NIEHS) found that tea tree and lavender oil can mimic the action of the female hormone oestrogen.
They can also block male hormones that control both masculine characteristics and inhibit the growth of breast tissue.
But NIEHS researcher and co-author Dr Ken Korach is cautious about saying the essential oils cause the breasts to grow.
“Although we found an association between exposure to these essential oils and gynaecomastia, further research is needed to determine the prevalence of prepubertal gynaecomastia in boys using products containing lavender and tea tree oils,” Dr Korach says.
