I did the clary sage oil, RLT, and EPO pessaries. All not the kicest things to do, I didn't think anyway...not sure if it help DS come, he came about 4days after his due date I think. I did have alot of prelabour though and by the time I got to hospital, I was 8cm dialated, so manybe it all helped me have an easier birth, but not actually bring it on, kwim??
RLT doesn't taste great, though I didn't find it totally repulsive either. I added a little honey to mine. I was drinking about 1ltr (at least) a day by your stage in pg! I used to make it, let it cool enough and just gulp it at once.
