I've used it (the tea). Tastes pretty average but I put a teaspoon of sugar in with it It's one of those things that you'll probably never know how different your labour was if you'd not taken it - but given all the info out there about it, I imagine it's true that it's good for you. Also good for after the birth as it helps your uterus shrink back down etc.

If anything, it's good for you psychologically as it gives you more confidence! In my case anyway!

You can also take it in tablet form if you hate the tea.
