Horny Goat Weed or epimedium, is traditional in Chinese medicine and has been used for centuries as a natural aid for both physical and mental vitality. Even though it has been used for men, women who take this supplement may experience increased sexual appetite. Epimedium appears to encourage blood flow, a key component to sexual desire, and also provides phytochemicals with similar actions as testosterone. This could be helpful for women experiencing hormonal fluctuations during PMS or menopause, balancing estrogen and estradiol levels in women. Studies have found that the chemical icariin in epimedium showed dynamic effects of bioactivity longer than a conventional menopause drug.
