Does evening primrose oil improve eczema?

Eczema is a multifactorial condition, but it has been proposed that a deficiency in essential fatty acids (e.g., linoleic acid) or an impaired ability to convert linoleic acid to GLA could be a contributing factor. While EPO is a good source of both linoleic acid and GLA, research has been very inconsistent, and ultimately, EPO taken orally is not thought to have any significant effect on the symptoms of eczema.^[1]
