Evening Primrose Oil: the latest clinical trials for atopic dermatitis, ‘dry eye’, and dyslexia
Evening Primrose Oil (EPO) is a mixture of omega-3 and other fatty acids extracted from the seeds of Oenothera biennis and related species. EPO was developed as a supplement in the 1980s and its significance increases with each passing year.
A list of recognized medical applications for this supplement includes:
- cardiovascular disease
- acute respiratory distress
- rheumatoid arthritis
- diabetic neuropathy
- chronic fatigue syndrome
- migraine headaches
- appetite control
- hemodialysis side effects
- osteoporosis
- breast cancer
- psoriasis, atopic dermatitis
- premenstrual syndrome
- cyclic breast pain
- immune deficiency
- dry eye syndrome
Medical research on EPO intensified into the 1990s and then tapered off as the subject became well understood. A number of
studies are still published each year, some of them exploring new applications, others refining our knowledge of existing
usages.
An article in the news at Easier.com discusses a new study of atopic dermatitis — the most common form of eczema. Sixty-five patients were randomly assigned to
take either EPO capsules or a sunflower oil placebo. After five months, 96% of the EPO users had improved, compared to only
32% of the placebo users.
Contact lens users who get Dry Eye problems might consider taking an Evening Primrose Oil supplement, according to a study
in the journal published by the British Contact Lens Association. In the study, 76 female soft contact lens wearers were treated
for 6 months with either an oral EPO supplement or an olive oil placebo. “The EPO group showed a significant improvement in
the specific symptom of ‘dryness’ at 3 and 6 months … and also a significant improvement in overall lens comfort…”
Even dyslexia has now fallen under the spell of Evening Primrose Oil. According to a study in the Journal of Medicinal Food, EPO taken for 5 months by 20 dyslexic children resulted in a 60% improvement in reading speed, and a 23% improvement in
‘motoric-perceptual’ velocity.
