Evening Primrose Oil Remedies


Evening Primrose Oil - Herbal Research
A WHO Organizational resource: Evening Primrose Oil - FULL REPORT


Medicinal uses supported by clinical data
 
Internally for symptomatic treatment of atopic eczema (2, 16-21), diabetic neuropathy (22, 23), and mastalgia (24-26). Clinical evidence for its use in the treatment of rheumatoid arthritis (27-30) is conflicting, as are the results of trials in women with premenstrual syndrome (31-35). Further well-designed clinical trials are needed to clarify these data. The results from clinical trials do not support the use of Oleum Oenotherae Biennis for the treatment of climacteric symptoms or psoriasis (36, 37).
 
Uses described in pharmacopoeias and in traditional systems of medicine
 
Topical use for the treatment of minor bruises and wounds (2).
 
Uses described in folk medicine, not supported by experimental or clinical data
 
Taken internally for the treatment of asthma, coughs, gastrointestinal disorders, pain and whooping cough (2, 9, 38).
