Nigella
Nigella sativa
Easy · Beginner friendlyAbout Nigella
Nigella sativa, black cumin or black seed, is a fine-textured annual from the Mediterranean and West Asia, grown for its small matte-black seeds. The plant stands 20-45 cm tall with threadlike foliage, pale blue to white flowers, and inflated seed capsules that dry into ornamental pods. The seeds have a warm, peppery, onion-oregano flavor and season breads, cheeses, pickles, and spice blends across the Middle East, North Africa, and South Asia. It is related to love-in-a-mist, but this species belongs more to the spice cabinet than the flower border. Give it sun, light soil, and a dry finish so the capsules can mature cleanly for harvest.

History
Nigella sativa, commonly called black cumin, black seed, kalonji, or habba sawda, is an annual herb native to southwestern Asia and the eastern Mediterranean. The small black seeds have been used as spice and traditional medicine for more than 3000 years; a bottle was found in Tutankhamun's tomb, and the Old Testament Book of Isaiah refers to fitches harvested by threshing. Prophet Muhammad is quoted in hadith as describing black seed as a cure for everything except death, cementing its importance in Islamic medicine.
Modern pharmacological research has focused on thymoquinone, the active compound, for antimicrobial, anti-inflammatory, and chemopreventive effects. The seeds flavor naan, Turkish breads, pickles, curries, and Bengali panch phoron spice mixes.
Blue or white starry flowers adorn the plant before forming inflated seed capsules. Cultivated for over 3,000 years across Egypt, the Middle East, India, and North Africa. Recently popular in American medicinal herb gardens for its well-documented traditional uses.
