Of 179 patients with eczema, 111 showed improvement after several weeks' supplementation with 8 capsules a day of evening primrose oil. Medications were reduced in many cases.

An analysis of nine controlled trials of evening primrose oil (Epogam) against eczema found that Epogam was significantly more effective than placebo, particularly against itching.

In a double-blind multicentre study on 145 eczema patients randomly assigned to fish oil or corn oil supplements there was a 30% improvement in clinical score in the fish oil group and a 24% improvement in the corn oil group.

In a double-blind study for 12 weeks, fish oil supplementation resulted in improvements in scaling and itching. Bjorneboe A et al: Effect of dietary supplementation with eicosapentaenoic acid in the treatment of atopic dermatitis. Br J Dermatol 117(4):463-9, 1987.
