By Mayo Clinic staffEvening primrose oil is a fatty acid (linoleic acid) supplement that's available over-the-counter. Some evidence suggests that evening primrose oil, taken alone or in combination with vitamin E, may help minimize cyclic breast pain that can be associated with breast cysts. Although the exact mechanism isn't clear, experts believe that women deficient in linoleic acid are more sensitive to hormonal fluctuations during the menstrual cycle, resulting in breast pain associated with breast cysts.
