Sativa, its pharmacognostic characteristics, morphological characteristics, and mechanism of actions, doses and medicinal uses. Nigella sativa [N. Sativa] is greatest form of healing medicine. It is also known as Prophetic Medicine as its use has been mentioned in Prophetic Hadit, as natural remedy for all the diseases except death. It is recommended on daily basis in Tibb-e-Nabwi [Prophetic Medicine].

N. sativa claimed to have anti-inflammatory, analgesic, hepato-protective, neuro-protective, gastro-protective and other useful properties. Biological and pharmacological effects are attributed to its two important constituents Thymoquinone [TQ] and Nigella sativa oil [NSO]. TQ has interaction with human serum albumin. Seeds containing volatile oils mainly Melanthin showed toxicity at larger doses. This report is a reference for all pharmaceutical researchers, physicians and biologists researching on N.Sativa and will open a door towards novel agent
