Raspberry Enjoy. Avoid during first trimester of pregnancy as may cause spontaneous miscarriage. Raspberry leaf and raspberry fruit can cause a softening of the pelvic muscles; improvement of uterine tone and blood supply can be seen. It can prevent postpartum hemorrhage. It is said to be useful the last trimester of pregnancy to facilitate an easier birth and shorter labor though research does not support this. Raspberry leaf tea is not recommended during the first trimester of pregnancy. It may facilitate a miscarriage.
ALERT if you are pregnant and prone to miscarriage avoid raspberries. Its mode of action is through relaxation of the pelvic muscles. I found raspberries very useful for pudendal nerve entrapment and vestibulitis.
