I drank the tea from about 30 weeks and took tablets from 34 or 35 weeks.

Not entirely sure how much it helped, (all of my labours were different) but I certainly had very efficient contractions, every 5 minutes right up until she was born. And I spent most of my labour on my back in bed

- ETA as an added bonus I believe it assists in milk production. I didn't take the tablets after Pie was born but I did drink the tea.
