What the problem was. In 20071 a scientific paper suggested that two essential oils, lavender and tea tree, have estrogenic activity i.e. the ability to mimic the action of the human hormone estrogen. This was demonstrated by laboratory data and was supported by clinical data from patients. The idea was met with a mixture of agreement and dissent. Much debate ensued but in the absence of additional data, the idea took hold. The original paper saying lavender and tea tree oil are estrogenic1 has been cited 284 times (Google Scholar, accessed 6 Dec 2016) since it was published and the information is now in several endocrinology textbooks.
