LinkPosted as an interesting piece, this cannot be used in lieu of a proper hormone program as it will not alter the actual estrogen levels in the body.
Excerpt:
After Bloch discussed the cases with Korach, the NIEHS researchers conducted experiments using human cells to determine if the oils mimic the effects of estrogen, the female hormone that stimulates breast tissue growth, or inhibited the effects of androgen, the hormone known to control masculine characteristics and inhibit the growth of breast tissue. The researchers tested the ability of the oils to modulate or inhibit gene expression.
"The results of our laboratory studies confirm that pure lavender and tea tree oils can mimic the actions of estrogens and inhibit the effects of androgens," said Korach. "This combinatorial activity makes them somewhat unique as endocrine disruptors."
[...]
The oils did not alter the levels of the usual forms of circulating estrogens and androgens in the boys. "We do not anticipate any long term effects on hormonal levels," said Derek Henley, Ph.D., the lead NIEHS author on the study. It is unknown whether the oils have similar endocrine disrupting effects in prepubertal girls, adolescents or adults.

Best bet is for the younger ones to avoid these oils in their pure form until more research can be done as a big enough disruption can have very serious consequences. Please see a doctor if you have any medical questions concerning your use of any topical ointments or medications.
