I have been drinking RRF tea since I found out I was preggers. I would definitly reccomend the loose herb rather than a tea already in tea bag form as usually the latter is a more inferior quality due to the processing. (I usually combine mine w/ nettles,oatstraw and spearmint btw) I have used traditional medicinals Pregnancy Tea as well but I think the loose herb is much more potent.
In alot of countries RRL is considered an abortificant btw, but it is my understanding it is the cultivated kind..I think this leads to the confusion over when you should start taking it (earlier vs. later). As with any herb though during PG if you feel crampy or whatnot after using it stop taking it!
I definitly reccommend Mountain Rose Herbs too, they have the best quality herbs!!!!
