Blackcurrant seed oil
Blackcurrant seed oil is derived from the seeds of Ribes nigrum. It contains an unusually high amount of omega-6 as well as a high amount of omega-3 fatty acids. It also contains linoleic acid as well as 2–4 percent stearidonic acid. There are some indications that blackcurrant seed oil is anti-inflammatory and cardioprotective. In European folk medicine, black currant once had a considerable reputation for controlling diarrhea, promoting urine output and reducing arthritic and rheumatic pains. It is primarily used medicinally and as a diet supplement.
