Black cumin seed has cancer prevention agents and calming properties. Black cumin seeds are otherwise called dark caraway, dark cumin, kalonji, and dark onion seeds. They come from Nigella sativa, a small plant with pale purple, blue, or white flowers that grows in Eastern Europe, Western Asia, and the Middle East. Since it is calming, the black cumin seed oil is incredible when weakened with a transporter oil to relieve scalp conditions that cause aggravation, flakiness, and affectability. Black cumin seed favorably affects several parameters related to heart disease risk including lowering total and LDL cholesterol, reducing inflammation, lowering blood pressure, reducing plaque formation. As far as natural hair goes, black seed oil may help in regrowing certain thinning areas on your scalp. It also reduces blood glucose, as well as diabetic-associated complications such as neuropathy.
