EVENING PRIMROSE OIL CAPSULES contain 500 mg of pure, cold-pressed seed oil made from evening primrose (Oenothera biennis) and 12 mg of natural vitamin E. The capsules are made from starch and therefore suitable for vegetarians and vegans.
Evening primrose oil is high in essential, polyunsaturated omega-6 fatty acids, such as linoleic acid and gamma-linolenic acid. Gamma-linolenic acid, in particular, makes the capsules valuable.
Evening primrose is a wildflower originally indigenous to North America. Native Americans already knew about and made use of the plant for diverse applications in their traditional medicine.
