I can assure you that raspberry leaf tea works. Not sure about the tabs, but I made the tea up myself, & you can also buy it as teabags. I drank it 4 times a day from being 6 month's pregnant (not supposed to take it under 3 month's as it can enhance contractions). My first labour was long and tiring (25 hour's), but the birth itself was easy. I needed no pain relief, and calmly held my partner's hand as it happened. I also needed no stitches, so I drank the tea throughout my 2nd pregnancy. The birth took 6 hours from start to finish, and it was wonderful. Yes - I'd advise the it!
