Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Evening primrose oil (EPO) has been used traditionally to support the reproductive system, particularly for female health concerns such as premenstrual syndrome (PMS), breast pain (mastalgia), and symptoms associated with menopause. The oil is a rich source of gamma-linolenic acid (GLA), an omega-6 fatty acid thought to help regulate prostaglandin synthesis, which may, in theory, influence menstrual symptoms and inflammation. Historically, EPO has been used in herbal and folk medicine to alleviate menstrual discomfort and support hormonal balance. However, scientific evidence supporting these uses is limited and inconsistent. Several studies and systematic reviews have found little or no clinically meaningful benefit for PMS, mastalgia, or menopausal symptoms compared to placebo. A few small trials have reported subjective improvements, but these results have not been robustly replicated in larger, well-designed studies. Consequently, while EPO continues to be popular as a natural remedy in reproductive health, its efficacy remains largely supported by tradition and anecdotal reports rather than strong scientific validation.
