Evening Primrose Oil Virgin 10%+ GLA (Oenothera Biennis)
The Greek name for this plant is Oinotheras and “biennis” is Latin for biennial…
The Evening Primrose originated in North America and was introduced to Europe in the early 1600s. Today it is common in the Mediterranean.
The Evening Primrose plant has golden-yellow flowers that burst into bloom during early evenings and soon die. This leads to the formation of pods that contain the tiny seeds we use to make Evening Primrose Oil.
All parts of the Evening Primrose plant are edible. Young Evening Primrose roots may be eaten hot or cold.
Expeller pressed from the seeds of the Evening Primrose, an herbaceous plant, this natural oil is high in gamma-lanolin acid and is very beneficial in the treatment of psoriasis, acne, PMS and cramps and has been known to lower blood pressure.
The therapeutic botanical properties of Evening Primrose Oil make it an excellent choice for a variety of medicinal and cosmetic purposes.
Described as an astringent, Evening Primrose Oil helps improve skin irritations, promotes healthy functioning of body tissue and hydrates skin. That’s primarily a result of the high amounts of gamma linoleic acid (GLA), an essential fatty acid, found in Evening Primrose Oil.
