How does evening primrose oil work?: Oenothera (Evening Primrose) is a natural herbal supplement derived from the seed of the evening primrose plant (there are about 145 different species in the genus Oenothera). Oenothera plants contain fatty acids that are metabolized to prostaglandins which have anti-inflammatory and pain relieving effects.
