    History of Wild Evening Primrose Oil*


    Evening Primrose, a native American herb, is so called for its primrose yellow flowers that blossom in the evening. Evening Primrose Oil contains gamma-linolenic acid (GLA), an important precursor of the hormone-like prostaglandin E1 (PGE1), which plays active roles in regulating human physiological functions.

    Our Evening Primrose Oil is international Quality Assurance Certified. We use only the highest quality oil from North America extracted by a proprietary cold press technique, never exceeding 40°C. This gentle refining process, which does not use any harmful solvent, removes unwanted pesticides and heavy metals while retaining its natural potency.

    Our stringent quality control requirement for both raw material selection and finished product testing allows us to guarantee the highest quality and product stability anywhere. They clearly differentiate our product from any others currently available in the market.
