Why does Efamol use the Rigel® Evening Primrose Oil?
Seeds from wild varieties of Evening Primrose will vary from crop to crop in the quantity and quality of their active ingredient, Gamma-Linolenic Acid (GLA), an essential fatty acid. Hence, the wild plant can not be relied upon for a consistent quantity or quality of oil. There are over 2000 species of Evening Primrose. Efamol plant scientists have made great progress in breeding improved crop plants from wild varieties through standard agricultural selection techniques (not genetic modification). These give the best yield in seed and top quality oil with a consistent percentage of GLA. As a result of this research, the equivalent of plant “patents” has been granted to Efamol for six varieties of their Evening Primrose plants. The most recent of these being a variety called “Rigel” (Oenothera spp.). Efamol Pure Evening Primrose Oil manufactured from Rigel® seeds contains up to 33% more GLA than found in wild plants.
