Nigella sativa (N. sativa) belongs to the botanical family of Ranunculaceae and commonly grows in the Eastern Europe, Middle East, and Western Asia. It is a small shrub with tapering green leaves and rosaceous white and purplish flowers. Its ripe fruit contains tiny seeds, dark black in color, known as “Habba Al-Sauda” or “Habba Al-Barakah” in Arabic and black seed in English. The seed and oil of N. sativa were frequently used in ancient remedies (Unani, Ayurveda, Chinese and Arabic) in Asian countries and in the middle east. Several uses of the N. sativa seed had been mentioned by Ibne-Sina (980–1037) in his famous book Al-Qanoon fi el-Tibb (El-Kadi and Kandil, 1986; Al-Jishi, 2000)
N. sativa and its ingredients have a wide range of pharmacological effects; immune-stimulatory, anti-inflammatory, hypoglycemic, antihypertensive, antiasthmatic, antimicrobial, antiparasitic, antioxidant and anticancer effects.
