Black cumin is the common name for Nigella sativa, a flowering annual plant native to southern Asia.
It can grow to one foot in height and has thin leaves with delicate flowers.
The fruit of black cumin is a large capsule that contains many seeds, which is the most commercially important part of the plant.
Traditionally, black cumin has been used for immune-system support, well-being, digestive health, respiratory issues, kidney and liver support, and heart health.
In Asia and the Middle East, black cumin seeds have long been used to treat asthma, bronchitis, rheumatism and other inflammatory diseases.
