Raspberry Leaf Tea has been used for ages to help tone the uterus to make it more effective when in labour. Generally it is advised to use from 32-33 weeks onwards starting gradually with one cup a day and then up to about 3 or 4 by week 38-39.
I got mine in Holland & Barratt (heath & heather brand) and doesnt taste too bad but then I found one made by clipper in tescos which has a higher concentration of Raspberry Leaf and tastes much better, even resembles raspberries!.
It can also be bought in tablet form if the tea isnt for you, again from Holland & Barratt.
