Since I discovered red raspberry leaf tea (RRL tea) with my 4th pregnancy, I have always drunk it diligently with the subsequent pregnancies. It has most certainly helped ME.
I wrote about it HERE and I have bought my stash of RRL Tea from Moms In Mind (it has since ceased operations) as well as from Brown Rice Paradise and SuperNature – the latter two are organic health food stores. You can find it at iHerb as well
However, I must say that you need to do your own research to determine if you would like to take it. Those with sensitive uterus may want to avoid it.
This time round, I started drinking just one cup of tea in the 1st trimester as I wanted to drink something other than water But that caused a lot of Braxton Hicks contractions (BH) which made me rather uncomfortable. So I had to stop drinking it. But I know some ladies who did not have any such reactions and they drank it from the start to the end of their pregnancies. So do your OWN research. I am just sharing what worked for me, a grand multipara!
