Red Raspberry As its name suggests, raspberry leaf is the leaf of the raspberry plant. It is somewhat well known for its benefits during pregnancy, but it is beneficial to women at all stages of life. It is naturally high in magnesium, potassium, and iron which makes it helpful for nausea, leg cramps, and improving sleep during pregnancy. The specific combination of nutrients in raspberry leaf makes it extremely beneficial for the female reproductive system: helping to eliminate/reduce fibroids. It strengthens the uterus and pelvic muscles which some midwives say leads to shorter and easier labor. It is good for overall uterine health.
