I used RLT tablets from about 32 weeks for memory then bought the tea at 38+4 and drank a lot that night and went into labour the next morning!

I had a 9 hour labour which my OB and midwife said would have been a lot faster had DD not been posterior and then stuck. I dialated quickly - 9cm in 6 hours...when I had my epidural then things slowed down for a bit But I definitely believe the RLT helped me for sure.
