It was suggested to me yesterday that Aromatherapy (specifically, applying oils such as lavender to the skin) can impact human hormones. Whilst the term "aromatherapy" sets off quackery alarms in my brain, the lady was quite insistent that this was true. so I was a little unsure what to believe. I *guess* the biological mechanism is there, after all, you can poison yourself through the epidermis I believe. Having goggled scholarly articles/clinical studies, I came back with nothing I trusted, but lots of hippy sites with no references.
If someone could help educate me a little, I would appreciate it
