Menopause

Alfalfa has been used traditionally to address symptoms of menopause. In particular, it can help alleviate hot flashes and night sweats, according to the University of Michigan Health System 2. Alfalfa's therapeutic action may be due to its constituent phytoestrogens -- substances that are molecularly similar to estrogen. Phytoestrogens may help balance estrogen-related activities in the body, which can be beneficial in menopause.
