Nigella Seed (Nigella sativa), or Black Cumin, is a revered pharmaceutical powerhouse whose seeds yield an oil rich in thymoquinone—a highly active crystalline compound with potent antihistaminic, anti-inflammatory, and immunomodulatory properties. Thymoquinone stabilizes mast cells to block histamine release, inhibits inflammatory pathways (COX and LOX), improves pancreatic beta-cell function, and promotes vasodilation.
