Research Context

Research context compiled from published sources

How does Evening Primrose Oil work?

GLA is a precursor to anti-inflammatory prostaglandins (PGE1). Modulates inflammatory pathways and may influence prostaglandin balance in ways that affect cyclical breast pain and skin barrier function. Proposed effects on vasomotor symptoms may relate to prostaglandin-mediated thermoregulation.
