The seeds of the evening primrose (a US wildflower that looks like a giant buttercup) are especially rich in the essential fatty acid gamma-linolenic acid (GLA).
This has long been thought to help people with eczema who have trouble converting fats from foods into GLA. In 2014, a pilot study of people with eczema backed up this theory.
Between 500 and 1,000 mg daily is thought best for preventative health.
