Sorry, I know this has been done to death, at least I've found some post from a couple of years ago. But there doesn't seem to be a consensus.
So, just wondered, what's the latest advice? I'm using olbas oil (and now tea tree oil, since I ran out of olbas) every night because, well, I find it relaxes me! It started when I had a cold and now I'm a bit addicted, if I'm honest!
I'm assuming it's fine because I'm inhaling, not massaging it directly into my skin (although I use tea tree directly on my terrible hormonal spotty skin three-four times a day!) but would be good to know if anyone has had any advice that it's bad for unborn baby??
