Can evening primrose oil bring on a period after menopause?

No scientific evidence supports the claim that evening primrose oil can induce menstruation after menopause. Menopause is a natural stage in a woman's life when her menstrual periods cease due to hormonal changes and the ovaries stop releasing eggs. Once menopause has occurred, a woman will no longer experience menstrual periods, regardless of any supplements or herbal remedies she may take.
