Borage or star flower oil is extracted from the blue star-shaped borage flower. The active component of borage oil is an essential fatty acid Gamma Linolenic Acid (GLA). Borage oil is now thoug ht to be a superior source of GLA. Star flower oil contains 22% GLA. This is far higher than the amount of GLA found in Evening Primrose Oil. GLA is an omega-6 fatty acid that is metabolised in the body to prostaglandins. Hormone-like substances which control many body processes.GLA has been shown to be particularly beneficial for female reproductive health. Breast-feeding mothers may also benefit from supplementing their diets with GLA. Breast milk is a very rich source of GLA and a considerable drain of GLA occurs from the motherÕs body when she breast-feeds. Star flower oil has also shown beneficial effects on the skin, due to its ability to help balance hormones.
