clary sage oil

Hi girls. I posted on the June thread aswell!! Got the clary sage oil today. Can anyone tell me how many drops to use in the bath to get things moving?? And can you use it with bubble bath or do you have to use it on its own in the water? Has anyone found that it worked for them?? Thanks girls!

On DD I used to just put a few drops in the bath probably 3 or 4 and then also put a few drops on a tissue to be sniffed every now and then. I was still induced but I think it helps make labour quicker and it is powerful stuff, I bought a bottle already but will wait until at least week 38 to use it.
