Evening primrose oil is a fatty acid (linoleic acid) supplement that's available over-the-counter. Some small studies suggest that evening primrose oil may ease menstrual cycle breast pain, sometimes associated with breast cysts. But more research is needed as studies have been small and uncontrolled, and the evidence isn't conclusive. Although the exact mechanism isn't clear, some experts believe that women deficient in linoleic acid are more sensitive to hormonal fluctuations during the menstrual cycle, resulting in breast pain.

Let your doctor know if you're taking any vitamins, herbal remedies or other dietary supplements.
