When the leaves of the evening primrose fade, the seeds of the plant are harvested by hand. The harvest is cleaned and dried before being transported to the oil mill. The oil is extracted from the seed capsules by mechanical pressing and then undergoes a careful refining process to guarantee the highest quality. The final product is a high-quality raffinate, which has a minimum content of 9% gamma-linolenic acid (GLA) and undergoes final analysis in our DIN ISO 17025 accredited laboratory before it is released for sale. Our pressed and refined evening primrose oil with at least 9% GLA meets the high requirements of the European Pharmacopoeia and is subject to a specially developed test plan that continuously ensures the quality of our product. Its high purity and quality standards make it ideal for a wide range of applications in the cosmetics, pharmaceutical and food sectors.
