Red Raspberry Leaf – You may take this herb during the entire cycle as it strengthens the uterine lining, thus helping to lengthen the luteal phase. But do ask your healthcare provider about continuing red raspberry leaf once pregnancy occurs. Usually, it should only be taken in the last trimester of pregnancy, because it “tones” the uterus
For centuries, women who were likely to have miscarriages took an herbal preventive that is also associated with a well-known fruit. Red raspberry leaf has the reputation of helping to relax the uterus. In addition to helping to prevent miscarriages, it is also recommended for infertility. ?Raspberry works by helping the fertilized egg attach to the uterine lining and stay attached,? says Jennifer Brett, N.D., a naturopathic doctor at the Wilton Naturopathic Center in Stratford, Connecticut.
Raspberry also seems to have a toning effect that helps women?s reproductive systems function normally. Nowadays, herbalists capitalize on this benefit by recommending raspberry for a variety of women?s problems, such as morning sickness, menstrual cramps, and heavy menstrual bleeding.
