Indians used this indigenous plant for a variety of ailments. Native American women chewed seeds of evening primrose to relieve premenstrual syndrome (PMS). Research has shown that one active ingredient of the seed oil is gamma-linolenic acid (GLA), an essential fatty acid in the production of prostaglandins. Deficiency of GLA causes abnormal sensitivity to prolactin, which may contribute to PMS. This may prove to be a very important medicinal plant. Studies have shown some effectiveness of evening primrose in treating eczema, in decreasing use of NSAIDs in rheumatoid arthritis patients, and in delaying the development of diabetic neuropathy. Studies of its use in cancer, hypercholesterolemia, peptic ulcers, ADHD, and other conditions are underway. This herbal remedy should not be taken by patients with epilepsy.
