The seeds of Nigella sativa have been used in folk medicine all over the world. The plant has been of interest due to its low degree of toxicity and beneficial pharmacological properties like antihypertensive, hypoglycemic, antifungal, anti-inflammatory, antihistaminic, antioxidant, along with significant anti-neuplastic activities. The present clinical study was undertaken to ascertain the adjuvant effect of Nigella seeds on various clinical and biochemical parameters of metabolic syndrome. After final diagnosis and considering inclusion and exclusion criteria, one hundred and fifty nine patients were enrolled in this study. Patients were divided into two groups. In Group I (standard group), patients were advised to take simvastatin 10 mg once a day, metformin 500 mg twice a day, Enalapril 10 mg once a day, Atenolol 50 mg once a day and clopidagrel 75 mg once a day for a period of six weeks. In Group II (Nigella seeds group), patients were advised the above standard medication plus Nigella seeds 250 mg twice daily for a period of six weeks. Blood sugar both fasting and postprandial, fasting lipid profile and different parameters of obesity were recorded before therapy and after completion of therapy. It was found that the addition of Nigella seeds provide beneficial effects in all the clinical and biochemical parameters for the adult’s treatment panel-III of metabolic disorders especially in fasting blood sugar, low density lipoproteins and high density lipoproteins. No sign of toxicity of the plant appeared in the Group II. Improvement in all other parameters like blood pressure, circumference of waist and serum triglyceride was also observed. Thus, Nigella seeds were found to be effective as an adjuvant therapy in patients of dyslipidemia and hyperglycemia.
