Evening primrose is a plant native to North and South America. It also grows throughout Europe and parts of Asia. It has yellow flowers which open at sunset and close during the day. The oil from the seeds of evening primrose is most often used to make medicine.
Evening primrose oil contains “fatty acids.” Some women with breast pain might not have high enough levels of certain ”fatty acids.” Fatty acids also seem to help decrease inflammation related to conditions such as arthritis and eczema.
