Red raspberry leaf tea contains phyto-progesterone properties. This may help to increase the levels of progesterone, which may, in turn, enhance fertility. Additionally, red raspberry leaf has been shown to reduce inflammation and strengthen the uterine lining.
Red raspberry leaf is perhaps one of the most historically venerated herbal uterine tonics. It is used during pregnancy to strengthen the uterus, improve labor outcome, and prevent excessive bleeding after birth.
