Black currants are high in antioxidants, including vitamin C. Along with the anthocyanins in black currants, these antioxidants can help to give your immune system a boost, allowing your body to fight infection and viruses more effectively. Black currants are rich in an omega-6 fatty acid called gamma-linoleic acid. Black currant is often recommended to those on a spiritual quest and for opening of the third eye to see the future for others as well as yourself.
