Atopic eczema unresponsive to evening primrose oil (linoleic and gamma-linolenic acids).

This study was designed to look at the effect of evening primrose oil (linoleic and gamma-linolenic acids) as an oral supplement for patients with atopic eczema. We used a double-blind, blocked crossover design with random assignment of patients to treatment groups. We used Wilcoxon's signed-ranks method of comparing changes during the trial. We observed no significant effect on erythema, scale, excoriation, lichenification, or overall severity in 123 patients with atopic eczema of average severity while they took oral doses of evening primrose oil (2 or 4 gm in children, 6 or 8 gm in adults).
