Oil's not well
This week’s New England Journal of Medicine carried a small, but alarming, report on those ever-so-calming substances lavender and tea tree oil.
The researchers noticed that three boys who were 4, 7 and 10 years old — so all prepubescent — developed gynecomastia. That’s jargon for enlarged breasts. Apparently, more than half of boys will show some signs of this during puberty but never before.
The first things doctors look for when something like this happens is exposure to the hormone estrogen. None of the boys had been exposed to any known estrogen source — no drugs, birth control pills or soy products. But two of the boys had been using products with lavender oil and one both lavender and tea tree oil. Once they stopped using the products, their breasts returned to normal.
Based on further experiments, the doctors are saying that these oils mimic the effects of estrogen and may be triggering hormone imbalances. Given the popularity of lavender-scented soap and skin lotions, shampoos and styling products, this seems to me to be big news. Okay, it’s three boys and some in vitro data, but it’s also published in a reputable journal and deserves investigation.
This seems to be just the beginning of a long and scary saga. What about women that may carry risk genes for estrogen-sensitive cancers? What about young girls? What about the rest of us? Should I throw away my lavender roller and tea tree oil body wash?

Comments
This is the silliest thing I have ever read.
Synthetic oestrogens are absolutely everywhere. You would have to go a damn long way (the moon) to avoid them nowadays. They're in so many water supplies that now wild fish are becoming intersexual. males everwhere are under threat. The contraceptive pill has been excreted into very sewage system, discharged into every river where there are humans, and to top it off the most commonly used garden chemical in the known universe is glyphosate, a you guessed it- synthetic oestrogen compound. Lavender oils my ----!
