Borage see oil is derived from the seeds of the Borago officinalis (borage). It is used medicinally as an anti-inflammatory, for treating arthritis, as well as certain skin conditions (e.g. atopic dermatitis) and respiratory inflammation. It has one of the highest amounts of gamma-linolenic acid (omega-6) of seed oils - higher than blackcurrant seed oil or evening primrose oil, to which it is considered similar. GLA makes up around 24% of the oil typically. A specific extraction process may offer purified products with 50%+ GLA content.
