Borage Oil (Borago officialis)
Borage oil is derived from the seeds of the borage plant (Borago officinalis), also known as Starflower. Borage oil is a rich source of the polyunsaturated fatty acid gamma-linolenic acid (GLA).
Borage has long been grown in kitchen gardens, both for its uses as a herb and for the sake of its flowers, which yield excellent honey. Today, the plant is grown as a commercial crop and harvested for the seed, which is nature's richest source of the fatty acid GLA. Oil produced from Borage seed contains between 20 and 24% GLA.
It is used medicinally as an anti-inflammatory, for treating rheumatoid arthritis, diabetes-associated neuropathy, and respiratory inflammation. It has also been used for certain skin conditions, but the evidence for this use is weak. The possible health benefits of borage oil are attributed to GLA, an unusual fatty acid which is only found in a few other plants such as evening primrose, hemp and blackcurrent seeds.
