What properties does black cumin have? Black cumin ( Nigella sativa ), also called black cumin, is a prized herbal ingredient used for its health-promoting properties. It is also an oil plant. Its seeds yield valuable oil rich in omega-6-9 essential fatty acids, including linoleic acid and oleic acid. The Swanson ® brand formula uses black cumin seed oil, which is a source of linoleic acid (LA) and oleic acid. Linoleic acid (LA) helps maintain normal blood cholesterol levels.
