Background & objectives: Stroke is third leading cause of death and disability in the most of human communities. The use of herbs and medicinal plants in different countries is increasing. Today, herbal medicine is used as alternative or complementary therapies with a fewer side effects. Nigella sativa has a rich medical and religious history. Oxidative stress has important role in the pathophysiology of stroke. As Nigella sativa has antioxidant effects, its administration may produce a protective effect against complications of this disease. We examined the effects of the treatment with Nigella sativa oil on the cerebral infarction and edema.

Methods: 48 Male Sprague-Dawley rats were divided into three groups, sham, control ischemic and Nigella sativa oil treated (2 ml/kg) ischemic groups. Transient focal cerebral ischemia was induced by 90-min-long occlusion of the left middle cerebral artery followed by 24-h-long reperfusion. Neurological deficit score was evaluated at the end of the reperfusion period. Thereafter, the animals were randomly selected and used for two projects: (i) Measurement of the infarct volumes and neurological outcome (ii) investigation of ischemic brain edema formation using a wet/dry method.

Results: Induction of cerebral ischemia in the control group produced considerable brain infarction in conjunction with impaired motor functions and severely brain edema. Treatment with Nigella sativa oil significantly reduced the infarct volume and improved the motor functions. The water content in the left (lesioned) hemisphere was considerably elevated in the control ischemic group. Administration of the Nigella sativa oil significantly lowered the water content in the ischemic lesioned hemisphere.

Conclusion: Treatment with Nigella sativa oil can noticeably decrease the ischemic brain injury, attenuate edema formation and improve motor disabilities.
